## What this PR does Adds TLS support to the Postgres managed service via the CNPG operator's built-in cert management. - Introduces a nullable `tls.enabled` field with tri-state semantics: when unset, defaults to the value of `external` (auto-on for externally published services, off for cluster-internal). Explicit `tls.enabled` always wins. - Uses CNPG's operator-managed TLS chain — the chart no longer renders its own cert-manager chain. The operator auto-generates a self-signed CA and signs server, client, and replication certs from it. The operator's default SAN list already covers the three built-in services (rw/r/ro) in four DNS forms each (bare, `.ns`, `.ns.svc`, `.ns.svc.<cluster-domain>`). - When `external: true` and TLS is on, the chart sets `spec.certificates.serverAltDNSNames` so the operator appends the external hostname `<release>.<tenant-host>` to the auto-generated leaf cert. In all other cases the chart leaves `spec.certificates` absent and the operator uses its default SAN set. - Trust anchor for clients: the operator-managed `<release>-ca` Opaque Secret (key `ca.crt`). Mount that key into client pods to verify TLS. Why operator-managed instead of a chart-side cert-manager chain: an earlier iteration that supplied `serverCASecret` and `serverTLSSecret` from a chart-rendered cert-manager chain failed the CNPG admission webhook with `missing ca.key secret data`. CNPG expects a `ca.key` field on `serverCASecret`, while cert-manager writes the private key under `tls.key`. Operator-managed mode avoids the schema fight entirely. Verified end-to-end on a sandbox cluster: cert chain is created by the operator within ~60 seconds, leaf cert's SAN list includes both the standard service forms and the external hostname, TLSv1.3 handshake via `openssl s_client -starttls postgres` against the rw service with the operator CA returns verify code 0. ### Release note ```release-note feat(postgres): add TLS support via CNPG operator-managed certificates with tri-state tls.enabled ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * TLS configuration added for PostgreSQL with a tri-state tls.enabled to control operator-managed certificate behavior and optional injection of the external hostname into server certificate SANs. * **Documentation** * Added TLS configuration guide, client CA retrieval and psql verification examples, and updated parameters reference. * **Tests** * Added integration tests covering tri-state TLS behavior and external-hostname injection scenarios. <!-- review_stack_entry_start --> [](https://app.coderabbit.ai/change-stack/cozystack/cozystack/pull/2686?utm_source=github_walkthrough&utm_medium=github&utm_campaign=change_stack) <!-- review_stack_entry_end --> <!-- end of auto-generated comment: release notes by coderabbit.ai -->
