A standalone Ingress because Harbor's chart cannot express a second host: expose.ingress.hosts.core is a single scalar, with no extraHosts like argo-cd and no secondaryingress like jenkins. The chart's own Ingress is untouched and keeps serving the nip.io name with its private-CA certificate; both names reach the same backends. The path split is load-bearing and was copied from this cluster's own generated Ingress rather than written from memory: /api/, /service/, /v2/ and /c/ go to harbor-core, everything else to harbor-portal. harbor-core is the API, auth and registry backend; harbor-portal is only the web UI. Sending /v2/ to the portal breaks every image pull, and it fails looking like an authentication problem rather than a routing one. What this deliberately does not do is make the new name primary. Harbor still advertises the nip.io address: externalURL is a single value handed to docker clients in Harbor's own API responses, so the UI may redirect there and a docker login against this hostname is issued a token endpoint pointing at the old one. Both resolve, so it works. Moving externalURL means moving every image reference in the cluster at the same time — running deployments, the dockerconfigjson auths key, toolshed's registry settings and its stored connection — which is its own change, not a line in this one.

devops-infra-argo-config
GitOps control plane for infrastructure tooling across Meesho's Kubernetes fleet.
This repo manages ArgoCD Application resources for every infrastructure tool (Contour, VictoriaMetrics, Grafana, Kyverno, KEDA, external-secrets, Vault, etc.) deployed across ~19 clusters. It uses an App-of-Applications pattern: one parent Application per cluster renders child Applications from a appSpec[] list via a generic Helm chart.
Each environment tracks a dedicated branch — merging to that branch triggers immediate ArgoCD auto-sync with no staging gate:
| Environment | Branch |
|---|---|
| Production (prd) | main |
| Staging (stg) | develop |
| Integration (int) | pre-prod |
How it works
incubator/<env>/<cluster>.yaml ← Parent Application (one per cluster)
└── points at generic-argo-apps-chart/ + values/<env>/<cluster>-values.yaml
└── renders one child Application per appSpec[] entry
└── sources charts + overrides from devops-infra-helm-charts
