No longer needed now that anonymous pull works — pairs with devops-helm-charts#efc2c4f dropping the corresponding pullSecret reference from demo-go-app's values. app-of-secretstores has automated prune, so this deletion applies on its own on next sync.
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
