Infrastructure

Storage and registry infrastructure used by the devops-lib pipeline per environment. External service dependencies live in downstreams.md.

Note: devops-lib is a Jenkins Shared Library — it does not own databases, caches, or message queues. The infrastructure listed here is used transiently during pipeline execution (artifact storage, container registry, Docker daemon).

Artifact storage

Built JARs and other build outputs are stored in object storage before being referenced at deploy time.

Type	Environment	Bucket / Path
GCS	prd / int	gcs-infr-dvps-meesho-artifacts-prd / gcs-infr-dvps-meesho-artifacts-int
GCS	stg	gcs-infr-dvps-meesho-artifacts-stg
GCS	ftr	gcs-infr-dvps-meesho-artifacts-ftr
S3 (AWS prd)	prd / int	meesho-prod-artifacts (ap-southeast-1, account 847438129436)
S3 (AWS dev)	stg / ftr	meesho-stg-artifacts (ap-south-1, account 766380763301)

Set as env.objBucket by constructParam.run().

Container registry

Docker images are built and pushed here by all build stages.

Type	Registry URL	Used for
GAR (GCP)	asia-southeast1-docker.pkg.dev/meesho-devops-admin-0622	All GCP builds — push target
GAR admin repo	asia-southeast1-docker.pkg.dev/meesho-devops-admin-0622/admin	Build-time base images
ECR (AWS prd)	847438129436.dkr.ecr.ap-southeast-1.amazonaws.com	AWS prd / int
ECR (AWS dev)	766380763301.dkr.ecr.ap-south-1.amazonaws.com	AWS stg / ftr

Set as env.registry / env.buildRegistry by constructParam.run().

Docker daemon (dind)

Build stages connect to a remote Docker daemon rather than a local socket. The host is injected as env.DOCKER_HOST.

Environment	Docker host
prd	dind-prd-svc
int	dind-int-svc
stg / ftr	dind-dev-new-svc.jenkins-new.svc.cluster.local

Jenkins agent pods (GCP)

GCP builds run in Kubernetes pods defined in resources/org/meesho/. Pod specs are referenced by environment:

Environment	Pod spec file
prd	resources/org/meesho/prd-pod.yaml
int	resources/org/meesho/int-pod.yaml
stg	resources/org/meesho/stg-pod.yaml
ftr	resources/org/meesho/ftr-pod.yaml

The container('devops-tools') container inside these pods runs all pipeline stages.

GCP projects

Environment	GCP project
prd	meesho-{bu}-prd-0622
int	meesho-shared-int-0525
stg / ftr	meesho-{bu}-dev-0622

Set as env.GCPProject by constructParam.run().
