Review Change Stack

Walkthrough

Control-plane Helm jobs and scheduled jobs now support configurable, templated initContainers. The chart values include commented PostgreSQL readiness examples. Existing job commands and Helm conditionals remain unchanged.

The ClickHouse migration example points its readiness check at PostgreSQL instead of ClickHouse, so deployments copied from the example may wait on the wrong service and miss the intended readiness validation. The PR is mergeable with explicit owner follow-up to correct this example.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the readiness target in the ClickHouse example.

The clickhouseMigration example waits for {{ include "postgresql.fullname" . }}. The consuming Job uses CLICKHOUSE_DSN in helm/cosmo/charts/controlplane/templates/clickhouse-migration.yaml, Lines 47-51, and is ordered after ClickHouse. If copied, this example can block on an absent PostgreSQL service and still not verify ClickHouse readiness. Use {{ include "clickhouse.fullname" . }} instead.
