# Cassandra
|
||||
A Cassandra Chart for Kubernetes
|
||||
|
||||
## Install Chart
|
||||
To install the Cassandra Chart into your Kubernetes cluster (This Chart requires persistent volume by default, you may need to create a storage class before install chart. To create storage class, see [Persist data](#persist_data) section)
|
||||
|
||||
```bash
|
||||
helm install --namespace "cassandra" -n "cassandra" incubator/cassandra
|
||||
```
|
||||
|
||||
After installation succeeds, you can get a status of Chart
|
||||
|
||||
```bash
|
||||
helm status "cassandra"
|
||||
```
|
||||
|
||||
If you want to delete your Chart, use this command
|
||||
```bash
|
||||
helm delete --purge "cassandra"
|
||||
```
|
||||
|
||||
## Upgrading
|
||||
|
||||
To upgrade your Cassandra release, simply run
|
||||
|
||||
```bash
|
||||
helm upgrade "cassandra" incubator/cassandra
|
||||
```
|
||||
|
||||
### 0.12.0
|
||||
|
||||
This version fixes https://github.com/helm/charts/issues/7803 by removing mutable labels in `spec.VolumeClaimTemplate.metadata.labels` so that it is upgradable.
|
||||
|
||||
Until this version, in order to upgrade, you have to delete the Cassandra StatefulSet before upgrading:
|
||||
```bash
|
||||
$ kubectl delete statefulset --cascade=false my-cassandra-release
|
||||
```
|
||||
|
||||
|
||||
## Persist data
|
||||
You need to create `StorageClass` before able to persist data in persistent volume.
|
||||
To create a `StorageClass` on Google Cloud, run the following
|
||||
|
||||
```bash
|
||||
kubectl create -f sample/create-storage-gce.yaml
|
||||
```
|
||||
|
||||
And set the following values in `values.yaml`
|
||||
|
||||
```yaml
|
||||
persistence:
|
||||
enabled: true
|
||||
```
|
||||
|
||||
If you want to create a `StorageClass` on other platform, please see documentation here [https://kubernetes.io/docs/user-guide/persistent-volumes/](https://kubernetes.io/docs/user-guide/persistent-volumes/)
|
||||
|
||||
When running a cluster without persistence, the termination of a pod will first initiate a decommissioning of that pod.
|
||||
Depending on the amount of data stored inside the cluster this may take a while. In order to complete a graceful
|
||||
termination, pods need to get more time for it. Set the following values in `values.yaml`:
|
||||
|
||||
```yaml
|
||||
podSettings:
|
||||
terminationGracePeriodSeconds: 1800
|
||||
```
|
||||
|
||||
## Install Chart with specific cluster size
|
||||
By default, this Chart will create a cassandra with 3 nodes. If you want to change the cluster size during installation, you can use `--set config.cluster_size={value}` argument. Or edit `values.yaml`
|
||||
|
||||
For example:
|
||||
Set cluster size to 5
|
||||
|
||||
```bash
|
||||
helm install --namespace "cassandra" -n "cassandra" --set config.cluster_size=5 incubator/cassandra/
|
||||
```
|
||||
|
||||
## Install Chart with specific resource size
|
||||
By default, this Chart will create a cassandra with CPU 2 vCPU and 4Gi of memory which is suitable for development environment.
|
||||
If you want to use this Chart for production, I would recommend to update the CPU to 4 vCPU and 16Gi. Also increase size of `max_heap_size` and `heap_new_size`.
|
||||
To update the settings, edit `values.yaml`
|
||||
|
||||
## Install Chart with specific node
|
||||
Sometime you may need to deploy your cassandra to specific nodes to allocate resources. You can use node selector by edit `nodes.enabled=true` in `values.yaml`
|
||||
For example, you have 6 vms in node pools and you want to deploy cassandra to node which labeled as `cloud.google.com/gke-nodepool: pool-db`
|
||||
|
||||
Set the following values in `values.yaml`
|
||||
|
||||
```yaml
|
||||
nodes:
|
||||
enabled: true
|
||||
selector:
|
||||
nodeSelector:
|
||||
cloud.google.com/gke-nodepool: pool-db
|
||||
```
|
||||
|
||||

## Scale cassandra
|
||||
When you want to change the cluster size of your cassandra, you can use the helm upgrade command.
|
||||
|
||||
```bash
|
||||
helm upgrade --set config.cluster_size=5 cassandra incubator/cassandra
|
||||
```
|
||||
|
||||
## Get cassandra status
|
||||
You can get your cassandra cluster status by running the command
|
||||
|
||||
```bash
|
||||
kubectl exec -it --namespace cassandra $(kubectl get pods --namespace cassandra -l app=cassandra-cassandra -o jsonpath='{.items[0].metadata.name}') nodetool status
|
||||
```
|
||||
|
||||

|
||||
## Benchmark
|
||||
You can use [cassandra-stress](https://docs.datastax.com/en/cassandra/3.0/cassandra/tools/toolsCStress.html) tool to run the benchmark on the cluster by the following command
|
||||
|
||||
```bash
|
||||
kubectl exec -it --namespace cassandra $(kubectl get pods --namespace cassandra -l app=cassandra-cassandra -o jsonpath='{.items[0].metadata.name}') cassandra-stress
|
||||
```
|
||||
|
||||
Example of `cassandra-stress` argument
|
||||
- Run both read and write with ration 9:1
|
||||
- Operator total 1 million keys with uniform distribution
|
||||
- Use QUORUM for read/write
|
||||
- Generate 50 threads
|
||||
- Generate result in graph
|
||||
- Use NetworkTopologyStrategy with replica factor 2
|
||||
|
||||
```bash
|
||||
cassandra-stress mixed ratio\(write=1,read=9\) n=1000000 cl=QUORUM -pop dist=UNIFORM\(1..1000000\) -mode native cql3 -rate threads=50 -log file=~/mixed_autorate_r9w1_1M.log -graph file=test2.html title=test revision=test2 -schema "replication(strategy=NetworkTopologyStrategy, factor=2)"

|
||||
## Requirements
|
||||
|
||||
* Kubernetes >= 1.14
|
||||
* [Helm][] >= 2.17.0
|
||||
* Minimum cluster requirements include the following to run this chart with
|
||||
default settings. All of these settings are configurable.
|
||||
* Three Kubernetes nodes to respect the default "hard" affinity settings
|
||||
* 1GB of RAM for the JVM heap
|
||||
|
||||
See [supported configurations][] for more details.
|
||||
|
||||
## Installing
|
||||
|
||||
This chart is tested with the latest 7.17.3 version.
|
||||
|
||||
### Install released version using Helm repository
|
||||
|
||||
* Add the Elastic Helm charts repo:
|
||||
`helm repo add elastic https://helm.elastic.co`
|
||||
|
||||
* Install it:
|
||||
- with Helm 3: `helm install elasticsearch --version <version> elastic/elasticsearch`
|
||||
- with Helm 2 (deprecated): `helm install --name elasticsearch --version <version> elastic/elasticsearch`
|
||||
|
||||
### Install development version from a branch
|
||||
|
||||
* Clone the git repo: `git clone git@github.com:elastic/helm-charts.git`
|
||||
|
||||
* Checkout the branch : `git checkout 7.17`
|
||||
|
||||
* Install it:
|
||||
- with Helm 3: `helm install elasticsearch ./helm-charts/elasticsearch --set imageTag=7.17.3`
|
||||
- with Helm 2 (deprecated): `helm install --name elasticsearch ./helm-charts/elasticsearch --set imageTag=7.17.3`
|
||||
|
||||
|
||||
## Upgrading
|
||||
|
||||
Please always check [CHANGELOG.md][] and [BREAKING_CHANGES.md][] before
|
||||
upgrading to a new chart version.
|
||||
|
||||
|
||||
## Usage notes
|
||||
|
||||
* This repo includes a number of [examples][] configurations which can be used
|
||||
as a reference. They are also used in the automated testing of this chart.
|
||||
* Automated testing of this chart is currently only run against GKE (Google
|
||||
Kubernetes Engine).
|
||||
* The chart deploys a StatefulSet and by default will do an automated rolling
|
||||
update of your cluster. It does this by waiting for the cluster health to become
|
||||
green after each instance is updated. If you prefer to update manually you can
|
||||
set `OnDelete` [updateStrategy][].
|
||||
* It is important to verify that the JVM heap size in `esJavaOpts` and to set
|
||||
the CPU/Memory `resources` to something suitable for your cluster.
|
||||
* To simplify chart and maintenance each set of node groups is deployed as a
|
||||
separate Helm release. Take a look at the [multi][] example to get an idea for
|
||||
how this works. Without doing this it isn't possible to resize persistent
|
||||
volumes in a StatefulSet. By setting it up this way it makes it possible to add
|
||||
more nodes with a new storage size then drain the old ones. It also solves the
|
||||
problem of allowing the user to determine which node groups to update first when
|
||||
doing upgrades or changes.
|
||||
* We have designed this chart to be very un-opinionated about how to configure
|
||||
Elasticsearch. It exposes ways to set environment variables and mount secrets
|
||||
inside of the container. Doing this makes it much easier for this chart to
|
||||
support multiple versions with minimal changes.

|
||||
|------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------|
|
||||
| `antiAffinityTopologyKey` | The [anti-affinity][] topology key. By default this will prevent multiple Elasticsearch nodes from running on the same Kubernetes node | `kubernetes.io/hostname` |
|
||||

||||
| `clusterHealthCheckParams` | The [Elasticsearch cluster health status params][] that will be used by readiness [probe][] command | `wait_for_status=green&timeout=1s` |
|
||||
| `clusterName` | This will be used as the Elasticsearch [cluster.name][] and should be unique per cluster in the namespace | `elasticsearch` |
|
||||
| `clusterDeprecationIndexing` | Enable or disable deprecation logs to be indexed (should be disabled when deploying master only node groups) | `false` |
|
||||
| `enableServiceLinks` | Set to false to disabling service links, which can cause slow pod startup times when there are many services in the current namespace. | `true` |
|
||||
| `envFrom` | Templatable string to be passed to the [environment from variables][] which will be appended to the `envFrom:` definition for the container | `[]` |
|
||||
| `esConfig` | Allows you to add any config files in `/usr/share/elasticsearch/config/` such as `elasticsearch.yml` and `log4j2.properties`. See [values.yaml][] for an example of the formatting | `{}` |

|
||||
| `esJvmOptions` | [Java options][] for Elasticsearch. Override the default JVM options by adding custom options files . See [values.yaml][] for an example of the formatting | `{}` |
|
||||
| `esMajorVersion` | Deprecated. Instead, use the version of the chart corresponding to your ES minor version. Used to set major version specific configuration. If you are using a custom image and not running the default Elasticsearch version you will need to set this to the version you are running (e.g. `esMajorVersion: 6`) | `""` |
|
||||
| `extraContainers` | Templatable string of additional `containers` to be passed to the `tpl` function | `""` |
|
||||

|
||||
| `imagePullPolicy` | The Kubernetes [imagePullPolicy][] value | `IfNotPresent` |
|
||||
| `imagePullSecrets` | Configuration for [imagePullSecrets][] so that you can use a private registry for your image | `[]` |
|
||||
| `imageTag` | The Elasticsearch Docker image tag | `7.17.3` |
|
||||

||||
| `minimumMasterNodes` | The value for [discovery.zen.minimum_master_nodes][]. Should be set to `(master_eligible_nodes / 2) + 1`. Ignored in Elasticsearch versions >= 7 | `2` |
|
||||
| `nameOverride` | Overrides the `clusterName` when used in the naming of resources | `""` |

## FAQ
|
||||
|
||||
### How to deploy this chart on a specific K8S distribution?
|
||||
|
||||
This chart is designed to run on production scale Kubernetes clusters with
|
||||
multiple nodes, lots of memory and persistent storage. For that reason it can be
|
||||
a bit tricky to run them against local Kubernetes environments such as
|
||||
[Minikube][].
|
||||
|
||||
This chart is highly tested with [GKE][], but some K8S distribution also
|
||||
requires specific configurations.
|
||||
|
||||
We provide examples of configuration for the following K8S providers:
|
||||
|
||||
- [Docker for Mac][]
|
||||
- [KIND][]
|
||||
- [Minikube][]
|
||||
- [MicroK8S][]
|
||||
- [OpenShift][]
|
||||
|
||||
### How to deploy dedicated nodes types?
|
||||
|
||||
All the Elasticsearch pods deployed share the same configuration. If you need to
|
||||
deploy dedicated [nodes types][] (for example dedicated master and data nodes),
|
||||
you can deploy multiple releases of this chart with different configurations
|
||||
while they share the same `clusterName` value.
|
||||
|
||||
For each Helm release, the nodes types can then be defined using `roles` value.
|
||||
|
||||
An example of Elasticsearch cluster using 2 different Helm releases for master
|
||||
and data nodes can be found in [examples/multi][].
|
||||
|
||||
#### Clustering and Node Discovery
|
||||
|
||||
This chart facilitates Elasticsearch node discovery and services by creating two
|
||||
`Service` definitions in Kubernetes, one with the name `$clusterName-$nodeGroup`
|
||||
and another named `$clusterName-$nodeGroup-headless`.
|
||||
Only `Ready` pods are a part of the `$clusterName-$nodeGroup` service, while all
|
||||
pods ( `Ready` or not) are a part of `$clusterName-$nodeGroup-headless`.
|
||||
|
||||
If your group of master nodes has the default `nodeGroup: master` then you can
|
||||
just add new groups of nodes with a different `nodeGroup` and they will
|
||||
automatically discover the correct master. If your master nodes have a different
|
||||
`nodeGroup` name then you will need to set `masterService` to
|
||||
`$clusterName-$masterNodeGroup`.
|
||||
|
||||
The chart value for `masterService` is used to populate
|
||||
`discovery.zen.ping.unicast.hosts` , which Elasticsearch nodes will use to
|
||||
contact master nodes and form a cluster.
|
||||
Therefore, to add a group of nodes to an existing cluster, setting
|
||||
`masterService` to the desired `Service` name of the related cluster is
|
||||
sufficient.
|
||||
|
||||
### How to deploy clusters with security (authentication and TLS) enabled?
|
||||
|
||||
This Helm chart can use existing [Kubernetes secrets][] to setup
|
||||
credentials or certificates for examples. These secrets should be created
|
||||
outside of this chart and accessed using [environment variables][] and volumes.
|
||||
|
||||
An example of Elasticsearch cluster using security can be found in
|
||||
[examples/security][].
|
||||
|
||||
### How to migrate from helm/charts stable chart?
|
||||
|
||||
If you currently have a cluster deployed with the [helm/charts stable][] chart
|
||||
you can follow the [migration guide][].
|
||||
|
||||
### How to install plugins?
|
||||
|
||||
The recommended way to install plugins into our Docker images is to create a
|
||||
[custom Docker image][].
|
||||
|
||||
The Dockerfile would look something like:
|
||||
|
||||
```
|
||||
ARG elasticsearch_version
|
||||
FROM docker.elastic.co/elasticsearch/elasticsearch:${elasticsearch_version}
|
||||
|
||||
RUN bin/elasticsearch-plugin install --batch repository-gcs
|
||||
```
|
||||
|
||||
And then updating the `image` in values to point to your custom image.
|
||||
|
||||
There are a couple reasons we recommend this.
|
||||
|
||||
1. Tying the availability of Elasticsearch to the download service to install
|
||||
plugins is not a great idea or something that we recommend. Especially in
|
||||
Kubernetes where it is normal and expected for a container to be moved to
|
||||
another host at random times.
|
||||
2. Mutating the state of a running Docker image (by installing plugins) goes
|
||||
against best practices of containers and immutable infrastructure.
|
||||
|
||||
### How to use the keystore?
|
||||
|
||||
#### Basic example
|
||||
|
||||
Create the secret, the key name needs to be the keystore key path. In this
|
||||
example we will create a secret from a file and from a literal string.
|
||||
|
||||
```
|
||||
kubectl create secret generic encryption-key --from-file=xpack.watcher.encryption_key=./watcher_encryption_key
|
||||
kubectl create secret generic slack-hook --from-literal=xpack.notification.slack.account.monitoring.secure_url='https://hooks.slack.com/services/asdasdasd/asdasdas/asdasd'
|
||||
```
|
||||
|
||||
To add these secrets to the keystore:
|
||||
|
||||
```
|
||||
keystore:
|
||||
- secretName: encryption-key
|
||||
- secretName: slack-hook
|
||||
```
|
||||
|
||||
#### Multiple keys
|
||||
|
||||
All keys in the secret will be added to the keystore. To create the previous
|
||||
example in one secret you could also do:
|
||||
|
||||
```
|
||||
kubectl create secret generic keystore-secrets --from-file=xpack.watcher.encryption_key=./watcher_encryption_key --from-literal=xpack.notification.slack.account.monitoring.secure_url='https://hooks.slack.com/services/asdasdasd/asdasdas/asdasd'
|
||||
```
|
||||
|
||||
```
|
||||
keystore:
|
||||
- secretName: keystore-secrets
|
||||
```
|
||||
|
||||
#### Custom paths and keys
|
||||
|
||||
If you are using these secrets for other applications (besides the Elasticsearch
|
||||
keystore) then it is also possible to specify the keystore path and which keys
|
||||
you want to add. Everything specified under each `keystore` item will be passed
|
||||
through to the `volumeMounts` section for mounting the [secret][]. In this
|
||||
example we will only add the `slack_hook` key from a secret that also has other
|
||||
keys. Our secret looks like this:
|
||||
|
||||
```
|
||||
kubectl create secret generic slack-secrets --from-literal=slack_channel='#general' --from-literal=slack_hook='https://hooks.slack.com/services/asdasdasd/asdasdas/asdasd'
|
||||
```
|
||||
|
||||
We only want to add the `slack_hook` key to the keystore at path
|
||||
`xpack.notification.slack.account.monitoring.secure_url`:
|
||||
|
||||
```
|
||||
keystore:
|
||||
- secretName: slack-secrets
|
||||
items:
|
||||
- key: slack_hook
|
||||
path: xpack.notification.slack.account.monitoring.secure_url
|
||||
```
|
||||
|
||||
You can also take a look at the [config example][] which is used as part of the
|
||||
automated testing pipeline.
|
||||
|
||||
### How to enable snapshotting?
|
||||
|
||||
1. Install your [snapshot plugin][] into a custom Docker image following the
|
||||
[how to install plugins guide][].
|
||||
2. Add any required secrets or credentials into an Elasticsearch keystore
|
||||
following the [how to use the keystore][] guide.
|
||||
3. Configure the [snapshot repository][] as you normally would.
|
||||
4. To automate snapshots you can use [Snapshot Lifecycle Management][] or a tool
|
||||
like [curator][].
|
||||
|
||||
### How to configure templates post-deployment?
|
||||
|
||||
You can use `postStart` [lifecycle hooks][] to run code triggered after a
|
||||
container is created.
|
||||
|
||||
Here is an example of `postStart` hook to configure templates:
|
||||
|
||||
```yaml
|
||||
lifecycle:
|
||||
postStart:
|
||||
exec:
|
||||
command:
|
||||
- bash
|
||||
- -c
|
||||
- |
|
||||
#!/bin/bash
|
||||
# Add a template to adjust number of shards/replicas
|
||||
TEMPLATE_NAME=my_template
|
||||
INDEX_PATTERN="logstash-*"
|
||||
SHARD_COUNT=8
|
||||
REPLICA_COUNT=1
|
||||
ES_URL=http://localhost:9200
|
||||
while [[ "$(curl -s -o /dev/null -w '%{http_code}\n' $ES_URL)" != "200" ]]; do sleep 1; done
|
||||
curl -XPUT "$ES_URL/_template/$TEMPLATE_NAME" -H 'Content-Type: application/json' -d'{"index_patterns":['\""$INDEX_PATTERN"\"'],"settings":{"number_of_shards":'$SHARD_COUNT',"number_of_replicas":'$REPLICA_COUNT'}}'
|
||||
```

# Config
|
||||
|
||||
This example deploy a single node Elasticsearch 7.17.3 with authentication and
|
||||
custom [values][].
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
* Create the required secrets: `make secrets`
|
||||
|
||||
* Deploy Elasticsearch chart with the default values: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/config-master 9200
|
||||
curl -u elastic:changeme http://localhost:9200/_cat/indices
|
||||
```
|
||||
|
||||
|
||||

# KIND
|
||||
|
||||
This example deploy a 3 nodes Elasticsearch 7.17.3 cluster on [Kind][]
|
||||
using [custom values][].
|
||||
|
||||
Note that this configuration should be used for test only and isn't recommended
|
||||
for production.
|
||||
|
||||
Note that Kind < 0.7.0 are affected by a [kind issue][] with mount points
|
||||
created from PVCs not writable by non-root users. [kubernetes-sigs/kind#1157][]
|
||||
fix it in Kind 0.7.0.
|
||||
|
||||
The workaround for Kind < 0.7.0 is to install manually
|
||||
[Rancher Local Path Provisioner][] and use `local-path` storage class for
|
||||
Elasticsearch volumes (see [Makefile][] instructions).
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
* For Kind >= 0.7.0: Deploy Elasticsearch chart with the default values: `make install`
|
||||
* For Kind < 0.7.0: Deploy Elasticsearch chart with `local-path` storage class: `make install-local-path`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:

# Migration Guide from helm/charts
|
||||
|
||||
There are two viable options for migrating from the community Elasticsearch Helm
|
||||
chart from the [helm/charts][] repo.
|
||||
|
||||
1. Restoring from Snapshot to a fresh cluster
|
||||
2. Live migration by joining a new cluster to the existing cluster.
|
||||
|
||||
## Restoring from Snapshot
|
||||
|
||||
This is the recommended and preferred option. The downside is that it will
|
||||
involve a period of write downtime during the migration. If you have a way to
|
||||
temporarily stop writes to your cluster then this is the way to go. This is also
|
||||
a lot simpler as it just involves launching a fresh cluster and restoring a
|
||||
snapshot following the [restoring to a different cluster guide][].
|
||||
|
||||
## Live migration
|
||||
|
||||
If restoring from a snapshot is not possible due to the write downtime then a
|
||||
live migration is also possible. It is very important to first test this in a
|
||||
testing environment to make sure you are comfortable with the process and fully
|
||||
understand what is happening.
|
||||
|
||||
This process will involve joining a new set of master, data and client nodes to
|
||||
an existing cluster that has been deployed using the [helm/charts][] community
|
||||
chart. Nodes will then be replaced one by one in a controlled fashion to
|
||||
decommission the old cluster.
|
||||
|
||||
This example will be using the default values for the existing helm/charts
|
||||
release and for the Elastic helm-charts release. If you have changed any of the
|
||||
default values then you will need to first make sure that your values are
|
||||
configured in a compatible way before starting the migration.
|
||||
|
||||
The process will involve a re-sync and a rolling restart of all of your data
|
||||
nodes. Therefore it is important to disable shard allocation and perform a synced
|
||||
flush like you normally would during any other rolling upgrade. See the
|
||||
[rolling upgrades guide][] for more information.
|
||||
|
||||
* The default image for this chart is
|
||||
`docker.elastic.co/elasticsearch/elasticsearch` which contains the default
|
||||
distribution of Elasticsearch with a [basic license][]. Make sure to update the
|
||||
`image` and `imageTag` values to the correct Docker image and Elasticsearch
|
||||
version that you currently have deployed.
|
||||
|
||||
* Convert your current helm/charts configuration into something that is
|
||||
compatible with this chart.
|
||||
|
||||
* Take a fresh snapshot of your cluster. If something goes wrong you want to be
|
||||
able to restore your data no matter what.
|
||||
|
||||
* Check that your clusters health is green. If not abort and make sure your
|
||||
cluster is healthy before continuing:
|
||||
|
||||
```
|
||||
curl localhost:9200/_cluster/health
|
||||
```
|
||||
|
||||
* Deploy new data nodes which will join the existing cluster. Take a look at the
|
||||
configuration in [data.yaml][]:
|
||||
|
||||
```
|
||||
make data
|
||||
```
|
||||
|
||||
* Check that the new nodes have joined the cluster (run this and any other curl
|
||||
commands from within one of your pods):
|
||||
|
||||
```
|
||||
curl localhost:9200/_cat/nodes
|
||||
```
|
||||
|
||||
* Check that your cluster is still green. If so we can now start to scale down
|
||||
the existing data nodes. Assuming you have the default amount of data nodes (2)
|
||||
we now want to scale it down to 1:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-data --replicas=1
|
||||
```
|
||||
|
||||
* Wait for your cluster to become green again:
|
||||
|
||||
```
|
||||
watch 'curl -s localhost:9200/_cluster/health'
|
||||
```
|
||||
|
||||
* Once the cluster is green we can scale down again:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-data --replicas=0
|
||||
```
|
||||
|
||||
* Wait for the cluster to be green again.
|
||||
* OK. We now have all data nodes running in the new cluster. Time to replace the
|
||||
masters by firstly scaling down the masters from 3 to 2. Between each step make
|
||||
sure to wait for the cluster to become green again, and check with
|
||||
`curl localhost:9200/_cat/nodes` that you see the correct amount of master
|
||||
nodes. During this process we will always make sure to keep at least 2 master
|
||||
nodes as to not lose quorum:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-master --replicas=2
|
||||
```
|
||||
|
||||
* Now deploy a single new master so that we have 3 masters again. See
|
||||
[master.yaml][] for the configuration:
|
||||
|
||||
```
|
||||
make master
|
||||
```
|
||||
|
||||
* Scale down old masters to 1:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-master --replicas=1
|
||||
```
|
||||
|
||||
* Edit the masters in [masters.yaml][] to 2 and redeploy:
|
||||
|
||||
```
|
||||
make master
|
||||
```
|
||||
|
||||
* Scale down the old masters to 0:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-master --replicas=0
|
||||
```
|
||||
|
||||
* Edit the [masters.yaml][] to have 3 replicas and remove the
|
||||
`discovery.zen.ping.unicast.hosts` entry from `extraEnvs` then redeploy the
|
||||
masters. This will make sure all 3 masters are running in the new cluster and
|
||||
are pointing at each other for discovery:
|
||||
|
||||
```
|
||||
make master
|
||||
```
|
||||
|
||||
* Remove the `discovery.zen.ping.unicast.hosts` entry from `extraEnvs` then
|
||||
redeploy the data nodes to make sure they are pointing at the new masters:
|
||||
|
||||
```
|
||||
make data
|
||||
```
|
||||
|
||||
* Deploy the client nodes:
|
||||
|
||||
```
|
||||
make client
|
||||
```
|
||||
|
||||
* Update any processes that are talking to the existing client nodes and point
|
||||
them to the new client nodes. Once this is done you can scale down the old
|
||||
client nodes:
|
||||
|
||||
```
|
||||
kubectl scale deployment my-release-elasticsearch-client --replicas=0
|
||||
```
|
||||
|
||||
* The migration should now be complete. After verifying that everything is
|
||||
working correctly you can cleanup leftover resources from your old cluster.

# Minikube
|
||||
|
||||
This example deploy a 3 nodes Elasticsearch 7.17.3 cluster on [Minikube][]
|
||||
using [custom values][].
|
||||
|
||||
If helm or kubectl timeouts occur, you may consider creating a minikube VM with
|
||||
more CPU cores or memory allocated.
|
||||
|
||||
Note that this configuration should be used for test only and isn't recommended
|
||||
for production.
|
||||
|
||||
|
||||
## Requirements
|
||||
|
||||
In order to properly support the required persistent volume claims for the
|
||||
Elasticsearch StatefulSet, the `default-storageclass` and `storage-provisioner`
|
||||
minikube addons must be enabled.
|
||||
|
||||
```
|
||||
minikube addons enable default-storageclass
|
||||
minikube addons enable storage-provisioner
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
* Deploy Elasticsearch chart with the default values: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/elasticsearch-master 9200
|
||||
curl localhost:9200/_cat/indices
|
||||

# Multi
|
||||
|
||||
This example deploy an Elasticsearch 7.17.3 cluster composed of 3 different Helm
|
||||
releases:
|
||||
|
||||
- `helm-es-multi-master` for the 3 master nodes using [master values][]
|
||||
- `helm-es-multi-data` for the 3 data nodes using [data values][]
|
||||
- `helm-es-multi-client` for the 3 client nodes using [client values][]
|
||||
|
||||
## Usage
|
||||
|
||||
* Deploy the 3 Elasticsearch releases: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/multi-master 9200

||||
curl -u elastic:changeme http://localhost:9200/_cat/indices
|

# Security
|
||||
|
||||
This example deploy a 3 nodes Elasticsearch 7.17.3 with authentication and
|
||||
autogenerated certificates for TLS (see [values][]).
|
||||
|
||||
Note that this configuration should be used for test only. For a production
|
||||
deployment you should generate SSL certificates following the [official docs][].
|
||||
|
||||
## Usage
|
||||
|
||||
* Create the required secrets: `make secrets`
|
||||
|
||||
* Deploy Elasticsearch chart with the default values: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/security-master 9200
|
||||
curl -u elastic:changeme https://localhost:9200/_cat/indices
|
||||
```
|
||||
|

# Upgrade
|
||||
|
||||
This example will deploy a 3 node Elasticsearch cluster chart using an old chart
|
||||
version, then upgrade it.
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
* Deploy and upgrade Elasticsearch chart with the default values: `make install`
|
||||
|
||||
|
||||
## Testing
|
||||
|
||||
You can also run [goss integration tests][] using `make test`.

# Grafana Helm Chart
|
||||
|
||||
* Installs the web dashboarding system [Grafana](http://grafana.org/)
|
||||
|
||||
## Get Repo Info
|
||||
|
||||
```console
|
||||
helm repo add grafana https://grafana.github.io/helm-charts
|
||||
helm repo update
|
||||
```
|
||||
|
||||
_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`:
|
||||
|
||||
```console
|
||||
helm install my-release grafana/grafana
|
||||
```
|
||||
|
||||
## Uninstalling the Chart
|
||||
|
||||
To uninstall/delete the my-release deployment:
|
||||
|
||||
```console
|
||||
helm delete my-release
|
||||
```
|
||||
|
||||
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
||||
|
||||
## Upgrading an existing Release to a new major version
|
||||
|
||||
A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an
|
||||
incompatible breaking change needing manual actions.
|
||||
|
||||
### To 4.0.0 (And 3.12.1)
|
||||
|
||||
This version requires Helm >= 2.12.0.
|
||||
|
||||
### To 5.0.0
|
||||
|
||||
You have to add --force to your helm upgrade command as the labels of the chart have changed.
|
||||
|
||||
### To 6.0.0
|
||||
|
||||
This version requires Helm >= 3.1.0.
|
||||

### To 7.0.0
|
||||
|
||||
For consistency with other Helm charts, the `global.image.registry` parameter was renamed
|
||||
to `global.imageRegistry`. If you were not previously setting `global.image.registry`, no action
|
||||
is required on upgrade. If you were previously setting `global.image.registry`, you will
|
||||
need to instead set `global.imageRegistry`.

### Example ingress with path
|
||||
|
||||
With grafana 6.3 and above
|
||||
|
||||
```yaml
|
||||
grafana.ini:
|
||||
server:
|
||||
domain: monitoring.example.com
|
||||
root_url: "%(protocol)s://%(domain)s/grafana"
|
||||
serve_from_sub_path: true
|
||||
ingress:
|
||||
enabled: true
|
||||
hosts:
|
||||
- "monitoring.example.com"
|
||||
path: "/grafana"
|
||||
```
|
||||
|
||||
### Example of extraVolumeMounts and extraVolumes
|
||||
|
||||
Configure additional volumes with `extraVolumes` and volume mounts with `extraVolumeMounts`.
|
||||
|
||||
Example for `extraVolumeMounts` and corresponding `extraVolumes`:
|
||||
|
||||
```yaml
|
||||
extraVolumeMounts:
|
||||
- name: plugins
|
||||
mountPath: /var/lib/grafana/plugins
|
||||
subPath: configs/grafana/plugins
|
||||
readOnly: false
|
||||
- name: dashboards
|
||||
mountPath: /var/lib/grafana/dashboards
|
||||
hostPath: /usr/shared/grafana/dashboards
|
||||
readOnly: false
|
||||
|
||||
extraVolumes:
|
||||
- name: plugins
|
||||
existingClaim: existing-grafana-claim
|
||||
- name: dashboards
|
||||
hostPath: /usr/shared/grafana/dashboards
|
||||
```
|
||||
|
||||
Volumes default to `emptyDir`. Set to `persistentVolumeClaim`,
|
||||
`hostPath`, `csi`, or `configMap` for other types. For a
|
||||
`persistentVolumeClaim`, specify an existing claim name with
|
||||
`existingClaim`.
|
||||
|
||||
## Import dashboards
|
||||
|
||||
There are a few methods to import dashboards to Grafana. Below are some examples and explanations as to how to use each method:
|
||||
|
||||
```yaml
|
||||
dashboards:
|
||||
default:
|
||||
some-dashboard:
|
||||
json: |
|
||||
{
|
||||
"annotations":
|
||||
|
||||
...
|
||||
# Complete json file here
|
||||
...
|
||||
|
||||
"title": "Some Dashboard",
|
||||
"uid": "abcd1234",
|
||||
"version": 1
|
||||
}
|
||||
custom-dashboard:
|
||||
# This is a path to a file inside the dashboards directory inside the chart directory
|
||||
file: dashboards/custom-dashboard.json
|
||||
prometheus-stats:
|
||||
# Ref: https://grafana.com/dashboards/2
|
||||
gnetId: 2
|
||||
revision: 2
|
||||
datasource: Prometheus
|
||||
loki-dashboard-quick-search:
|
||||
gnetId: 12019
|
||||
revision: 2
|
||||
datasource:
|
||||
- name: DS_PROMETHEUS
|
||||
value: Prometheus
|
||||
- name: DS_LOKI
|
||||
value: Loki
|
||||
local-dashboard:
|
||||
url: https://raw.githubusercontent.com/user/repository/master/dashboards/dashboard.json
|
||||
```
|
||||
|
||||
## BASE64 dashboards
|
||||
|
||||
Dashboards could be stored on a server that does not return JSON directly and instead of it returns a Base64 encoded file (e.g. Gerrit)
|
||||
A new parameter has been added to the url use case so if you specify a b64content value equals to true after the url entry a Base64 decoding is applied before save the file to disk.
|
||||
If this entry is not set or is equals to false not decoding is applied to the file before saving it to disk.
|
||||
|
||||
### Gerrit use case
|
||||
|
||||
Gerrit API for download files has the following schema: <https://yourgerritserver/a/{project-name}/branches/{branch-id}/files/{file-id}/content> where {project-name} and
|
||||
{file-id} usually has '/' in their values and so they MUST be replaced by %2F so if project-name is user/repo, branch-id is master and file-id is equals to dir1/dir2/dashboard
|
||||
the url value is <https://yourgerritserver/a/user%2Frepo/branches/master/files/dir1%2Fdir2%2Fdashboard/content>
|
||||
|
||||
## Sidecar for dashboards
|
||||
|
||||
If the parameter `sidecar.dashboards.enabled` is set, a sidecar container is deployed in the grafana
|
||||
pod. This container watches all configmaps (or secrets) in the cluster and filters out the ones with
|
||||
a label as defined in `sidecar.dashboards.label`. The files defined in those configmaps are written
|
||||
to a folder and accessed by grafana. Changes to the configmaps are monitored and the imported
|
||||
dashboards are deleted/updated.
|
||||
|
||||
A recommendation is to use one configmap per dashboard, as a reduction of multiple dashboards inside
|
||||
one configmap is currently not properly mirrored in grafana.
|
||||
|
||||
Example dashboard config:
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: sample-grafana-dashboard
|
||||
labels:
|
||||
grafana_dashboard: "1"
|
||||
data:
|
||||
k8s-dashboard.json: |-
|
||||
[...]
|
||||
```
|
||||
|
||||
## Sidecar for datasources
|
||||
|
||||
If the parameter `sidecar.datasources.enabled` is set, an init container is deployed in the grafana
|
||||
pod. This container lists all secrets (or configmaps, though not recommended) in the cluster and
|
||||
filters out the ones with a label as defined in `sidecar.datasources.label`. The files defined in
|
||||
those secrets are written to a folder and accessed by grafana on startup. Using these yaml files,
|
||||
the data sources in grafana can be imported.
|
||||
|
||||
Should you aim for reloading datasources in Grafana each time the config is changed, set `sidecar.datasources.skipReload: false` and adjust `sidecar.datasources.reloadURL` to `http://<svc-name>.<namespace>.svc.cluster.local/api/admin/provisioning/datasources/reload`.
|
||||
|
||||
Secrets are recommended over configmaps for this usecase because datasources usually contain private
|
||||
data like usernames and passwords. Secrets are the more appropriate cluster resource to manage those.
|
||||
|
||||
Example values to add a postgres datasource as a kubernetes secret:
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: Secret
|
||||
metadata:
|
||||
name: grafana-datasources
|
||||
labels:
|
||||
grafana_datasource: 'true' # default value for: sidecar.datasources.label
|
||||
stringData:
|
||||
pg-db.yaml: |-
|
||||
apiVersion: 1
|
||||
datasources:
|
||||
- name: My pg db datasource
|
||||
type: postgres
|
||||
url: my-postgresql-db:5432
|
||||

|
||||
secureJsonData:
|
||||

|
||||
jsonData:
|
||||
database: my_datase
|
||||
sslmode: 'disable' # disable/require/verify-ca/verify-full
|
||||
maxOpenConns: 0 # Grafana v5.4+
|
||||
maxIdleConns: 2 # Grafana v5.4+
|
||||
connMaxLifetime: 14400 # Grafana v5.4+
|
||||
postgresVersion: 1000 # 903=9.3, 904=9.4, 905=9.5, 906=9.6, 1000=10
|
||||
timescaledb: false
|
||||
# <bool> allow users to edit datasources from the UI.
|
||||
editable: false
|
||||
```
|
||||
|
||||
Example values to add a datasource adapted from [Grafana](http://docs.grafana.org/administration/provisioning/#example-datasource-config-file):
|
||||
|
||||
```yaml
|
||||
datasources:
|
||||
datasources.yaml:
|
||||
apiVersion: 1
|
||||
datasources:
|
||||
# <string, required> name of the datasource. Required
|
||||
- name: Graphite
|
||||
# <string, required> datasource type. Required
|
||||
type: graphite
|
||||
# <string, required> access mode. proxy or direct (Server or Browser in the UI). Required
|

|
||||
# <string> url
|
||||

|
||||
# <string> database password, if used
|
||||
password:
|
||||
# <string> database user, if used
|
||||

|
||||
version: 1
|
||||
# <bool> allow users to edit datasources from the UI.
|
||||
editable: false
|
||||
```
|
||||
|
||||
## Sidecar for notifiers
|
||||
|
||||
If the parameter `sidecar.notifiers.enabled` is set, an init container is deployed in the grafana
|
||||
pod. This container lists all secrets (or configmaps, though not recommended) in the cluster and
|
||||
filters out the ones with a label as defined in `sidecar.notifiers.label`. The files defined in
|
||||
those secrets are written to a folder and accessed by grafana on startup. Using these yaml files,
|
||||
the notification channels in grafana can be imported. The secrets must be created before
|
||||
`helm install` so that the notifiers init container can list the secrets.
|
||||
|
||||
Secrets are recommended over configmaps for this usecase because alert notification channels usually contain
|
||||
private data like SMTP usernames and passwords. Secrets are the more appropriate cluster resource to manage those.
|
||||
|
||||
Example datasource config adapted from [Grafana](https://grafana.com/docs/grafana/latest/administration/provisioning/#alert-notification-channels):
|
||||
|
||||
```yaml
|
||||
notifiers:
|
||||
- name: notification-channel-1
|
||||
type: slack
|
||||
uid: notifier1
|
||||
# either
|
||||
org_id: 2
|
||||
# or
|
||||
org_name: Main Org.
|
||||
is_default: true
|
||||
send_reminder: true
|
||||
frequency: 1h
|
||||
disable_resolve_message: false
|
||||
# See `Supported Settings` section for settings supporter for each
|
||||
# alert notification type.
|
||||
settings:
|
||||
recipient: 'XXX'
|
||||
token: 'xoxb'
|
||||
uploadImage: true
|
||||
url: https://slack.com
|
||||
|
||||
delete_notifiers:
|
||||
- name: notification-channel-1
|
||||
uid: notifier1
|
||||
org_id: 2
|
||||
- name: notification-channel-2
|
||||
# default org_id: 1
|
||||
```
|
||||
|
||||
## Sidecar for alerting resources
|
||||
|
||||
If the parameter `sidecar.alerts.enabled` is set, a sidecar container is deployed in the grafana
|
||||
pod. This container watches all configmaps (or secrets) in the cluster (namespace defined by `sidecar.alerts.searchNamespace`) and filters out the ones with
|
||||
a label as defined in `sidecar.alerts.label` (default is `grafana_alert`). The files defined in those configmaps are written
|
||||
to a folder and accessed by grafana. Changes to the configmaps are monitored and the imported alerting resources are updated, however, deletions are a little more complicated (see below).
|
||||
|
||||
This sidecar can be used to provision alert rules, contact points, notification policies, notification templates and mute timings as shown in [Grafana Documentation](https://grafana.com/docs/grafana/next/alerting/set-up/provision-alerting-resources/file-provisioning/).
|
||||
|
||||
To fetch the alert config which will be provisioned, use the alert provisioning API ([Grafana Documentation](https://grafana.com/docs/grafana/next/developers/http_api/alerting_provisioning/)).
|
||||
You can use either JSON or YAML format.
|
||||
|
||||
Example config for an alert rule:
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: sample-grafana-alert
|
||||
labels:
|
||||
grafana_alert: "1"
|
||||
data:
|
||||
k8s-alert.yml: |-
|
||||
apiVersion: 1
|
||||
groups:
|
||||
- orgId: 1
|
||||
name: k8s-alert
|
||||
[...]
|
||||
```
|
||||
|
||||
To delete provisioned alert rules is a two step process, you need to delete the configmap which defined the alert rule
|
||||
and then create a configuration which deletes the alert rule.
|
||||
|
||||
Example deletion configuration:
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: delete-sample-grafana-alert
|
||||
namespace: monitoring
|
||||
labels:
|
||||
grafana_alert: "1"
|
||||
data:
|
||||
delete-k8s-alert.yml: |-
|
||||
apiVersion: 1
|
||||
deleteRules:
|
||||
- orgId: 1
|
||||
uid: 16624780-6564-45dc-825c-8bded4ad92d3
|
||||
```
|
||||
|
||||
## Statically provision alerting resources
|
||||
If you don't need to change alerting resources (alert rules, contact points, notification policies and notification templates) regularly you could use the `alerting` config option instead of the sidecar option above.
|
||||
This will grab the alerting config and apply it statically at build time for the helm file.
|
||||
|
||||
There are two methods to statically provision alerting configuration in Grafana. Below are some examples and explanations as to how to use each method:
|
||||
|
||||
```yaml
|
||||
alerting:
|
||||
team1-alert-rules.yaml:
|
||||
file: alerting/team1/rules.yaml
|
||||
team2-alert-rules.yaml:
|
||||
file: alerting/team2/rules.yaml
|
||||
team3-alert-rules.yaml:
|
||||
file: alerting/team3/rules.yaml
|
||||
notification-policies.yaml:
|
||||
file: alerting/shared/notification-policies.yaml
|
||||
notification-templates.yaml:
|
||||
file: alerting/shared/notification-templates.yaml
|
||||
contactpoints.yaml:
|
||||
apiVersion: 1
|
||||
contactPoints:
|
||||
- orgId: 1
|
||||
name: Slack channel
|
||||
receivers:
|
||||
- uid: default-receiver
|
||||
type: slack
|
||||
settings:
|
||||
# Webhook URL to be filled in
|
||||
url: ""
|
||||
# We need to escape double curly braces for the tpl function.
|
||||
text: '{{ `{{ template "default.message" . }}` }}'
|
||||
title: '{{ `{{ template "default.title" . }}` }}'
|
||||
```
|
||||
|
||||
The two possibilities for static alerting resource provisioning are:
|
||||
|
||||
* Inlining the file contents as shown for contact points in the above example.
|
||||
* Importing a file using a relative path starting from the chart root directory as shown for the alert rules in the above example.
|
||||
|
||||
### Important notes on file provisioning
|
||||
|
||||
* The format of the files is defined in the [Grafana documentation](https://grafana.com/docs/grafana/next/alerting/set-up/provision-alerting-resources/file-provisioning/) on file provisioning.
|
||||
* The chart supports importing YAML and JSON files.
|
||||
* The filename must be unique, otherwise one volume mount will overwrite the other.
|
||||
* In case of inlining, double curly braces that arise from the Grafana configuration format and are not intended as templates for the chart must be escaped.
|
||||
* The number of total files under `alerting:` is not limited. Each file will end up as a volume mount in the corresponding provisioning folder of the deployed Grafana instance.
|
||||
* The file size for each import is limited by what the function `.Files.Get` can handle, which suffices for most cases.
|
||||
|
||||
## How to serve Grafana with a path prefix (/grafana)
|
||||
|
||||
In order to serve Grafana with a prefix (e.g., <http://example.com/grafana>), add the following to your values.yaml.
|
||||
|
||||
```yaml
|
||||
ingress:
|
||||
enabled: true
|
||||
annotations:
|
||||
kubernetes.io/ingress.class: "nginx"
|
||||
nginx.ingress.kubernetes.io/rewrite-target: /$1
|
||||
nginx.ingress.kubernetes.io/use-regex: "true"
|
||||
|
||||
path: /grafana/?(.*)
|
||||
hosts:
|
||||
- k8s.example.dev
|
||||
|
||||
grafana.ini:
|
||||
server:
|
||||
root_url: http://localhost:3000/grafana # this host can be localhost
|
||||
```
|
||||
|
||||
## How to securely reference secrets in grafana.ini
|
||||
|
||||
This example uses Grafana [file providers](https://grafana.com/docs/grafana/latest/administration/configuration/#file-provider) for secret values and the `extraSecretMounts` configuration flag (Additional grafana server secret mounts) to mount the secrets.
|
||||
|
||||
In grafana.ini:
|
||||
|
||||
```yaml
|
||||
grafana.ini:
|
||||
[auth.generic_oauth]
|
||||
enabled = true
|
||||
client_id = $__file{/etc/secrets/auth_generic_oauth/client_id}
|
||||
client_secret = $__file{/etc/secrets/auth_generic_oauth/client_secret}
|
||||
```
|
||||
|
||||
Existing secret, or created along with helm:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: v1
|
||||
kind: Secret
|
||||
metadata:
|
||||
name: auth-generic-oauth-secret
|
||||
type: Opaque
|
||||
stringData:
|
||||
client_id: <value>
|
||||
client_secret: <value>
|
||||
```
|
||||
|
||||
Include in the `extraSecretMounts` configuration flag:
|
||||
|
||||
```yaml
|
||||
- extraSecretMounts:
|
||||
- name: auth-generic-oauth-secret-mount
|
||||
secretName: auth-generic-oauth-secret
|
||||
defaultMode: 0440
|
||||
mountPath: /etc/secrets/auth_generic_oauth
|
||||
readOnly: true
|
||||
```
|
||||
|
||||
### extraSecretMounts using a Container Storage Interface (CSI) provider
|
||||
|
||||
This example uses a CSI driver e.g. retrieving secrets using [Azure Key Vault Provider](https://github.com/Azure/secrets-store-csi-driver-provider-azure)
|
||||
|
||||
```yaml
|
||||
- extraSecretMounts:
|
||||
- name: secrets-store-inline
|
||||
mountPath: /run/secrets
|
||||
readOnly: true
|
||||
csi:
|
||||
driver: secrets-store.csi.k8s.io
|
||||
readOnly: true
|
||||
volumeAttributes:
|
||||
secretProviderClass: "my-provider"
|
||||
nodePublishSecretRef:
|
||||
name: akv-creds
|
||||
```
|
||||

This chart supports enabling [remote image rendering](https://github.com/grafana/grafana-image-renderer/blob/master/README.md#run-in-docker)
|
||||
|
||||
```yaml
|
||||
imageRenderer:
|
||||
enabled: true
|
||||
```
|
||||
|
||||
### Image Renderer NetworkPolicy
|
||||
|
||||
By default the image-renderer pods will have a network policy which only allows ingress traffic from the created grafana instance
|
||||
|
||||
### High Availability for unified alerting
|
||||
|
||||
If you want to run Grafana in a high availability cluster you need to enable
|
||||
the headless service by setting `headlessService: true` in your `values.yaml`
|
||||
file.
|
||||
|
||||
As next step you have to setup the `grafana.ini` in your `values.yaml` in a way
|
||||
that it will make use of the headless service to obtain all the IPs of the
|
||||
cluster. You should replace ``{{ Name }}`` with the name of your helm deployment.
|
||||
|
||||
```yaml
|
||||
grafana.ini:
|
||||
...
|
||||
unified_alerting:
|
||||
enabled: true
|
||||
ha_peers: {{ Name }}-headless:9094
|
||||
ha_listen_address: ${POD_IP}:9094
|
||||
ha_advertise_address: ${POD_IP}:9094
|
||||
|
||||
alerting:
|
||||
enabled: false
|
||||
```

1. Get your '{{ .Values.adminUser }}' user password by running:
|
||||
|
||||
kubectl get secret --namespace {{ include "grafana.namespace" . }} {{ .Values.admin.existingSecret | default (include "grafana.fullname" .) }} -o jsonpath="{.data.{{ .Values.admin.passwordKey | default "admin-password" }}}" | base64 --decode ; echo
|

2. The Grafana server can be accessed via port {{ .Values.service.port }} on the following DNS name from within your cluster:
|
||||
|
||||
{{ include "grafana.fullname" . }}.{{ include "grafana.namespace" . }}.svc.cluster.local
|
||||
{{ if .Values.ingress.enabled }}
|
||||
If you bind grafana to 80, please update values in values.yaml and reinstall:
|
||||
```
|
||||
securityContext:
|
||||
runAsUser: 0
|
||||
runAsGroup: 0
|

- "sh"
|

- "/run.sh"
|

```
|

Details refer to https://grafana.com/docs/installation/configuration/#http-port.
|

Or grafana would always crash.
|

Get the Grafana URL to visit by running these commands in the same shell:
|

{{- if contains "NodePort" .Values.service.type }}
|

echo http://$NODE_IP:$NODE_PORT
|

{{- else if contains "LoadBalancer" .Values.service.type }}
|

NOTE: It may take a few minutes for the LoadBalancer IP to be available.
