Upgrades

The product version pins a tested component matrix. Upgrading means moving the whole platform to a new released version as one set — not drifting individual components. The exact images tested for a release are the ones that ship to you.

Who this is for

Platform engineers upgrading an existing installation to a newer product version.

One version, one tested set

Each product version (e.g. v1.8.0) pins the versions of every component beside it — Kubernetes baseline, the gateway, control plane, console, databases, identity, observability, and the built-in plugins. That set is tested together. Bumping the product version moves the whole set; you don't upgrade one plugin or one database in isolation.

You select the version through the chart and its image tags. See the Configuration reference for the image value structure and Release notes for what each version delivers.

Build-once, promote-by-retag

Behind a release, the exact image digest that was tested is the one that ships — images are promoted by retagging, not rebuilt between environments. So the artifact you run in production is bit-for-bit the one that passed testing. You don't need to reproduce a build; you pull the released tag.

Upgrade procedure

1. Read the release notes for the target version — note any new required values or behavior changes.

2. Back up the control-plane PostgreSQL first — see Backup & DR.

3. Update your image tags / chart version to the target release in your values.

4. Apply with helm upgrade:

   helm upgrade opsta-ai-gateway oci://ghcr.io/opsta/charts/opsta-ai-gateway \
     -n opsta-ai-gateway -f values.yaml -f secrets-values.yaml

5. Watch readiness. The control plane runs any new database migrations and a reconcile before reporting ready, so the gateway is never serving against a half-migrated state.

   kubectl -n opsta-ai-gateway rollout status deploy/control-plane

6. Smoke-test a request through the gateway and a console sign-in.

Rolling upgrades in HA

In high-availability mode, PodDisruptionBudgets and anti-affinity keep a quorum of each component up during the rollout, so the upgrade is non-disruptive to live traffic. Database failover is handled by CloudNativePG.

Config you changed by hand will be reconciled

Tenant data (consumers, budgets, providers, guardrails) is owned by the control plane and survives upgrades. The chart owns product-level config — anything you changed outside the chart can be reset on upgrade, so make changes through values, not by editing live resources.

Rolling back

helm rollback returns the chart to the previous release. Because PostgreSQL holds the source of truth, restore a database backup taken before the upgrade if a migration needs to be reversed. Test upgrades in a staging environment first.

Next steps

• Backup & DR — take a backup before every upgrade.
• Release notes — what changed between versions.
