Add optional ServiceAccount configuration for cloud IAM integration (AWS IRSA, GCP Workload Identity). Disabled by default to maintain backward compatibility. - Add serviceAccount section to values.yaml - Add serviceAccountName helper to _helpers.tpl - Create serviceaccount.yaml template - Attach serviceAccountName to all Deployments and Jobs - Add schema validation in values.schema.json Signed-off-by: ppippi-dev <wjdqlsdlsp@naver.com>
The original PR missed adding serviceAccountName to the pgbouncer deployment template. This adds it for consistency with all other deployments and jobs in the chart. Signed-off-by: Mihai Criveti <crivetimihai@gmail.com>
- Add CHANGELOG entry for ServiceAccount support feature - Add helm-docs comments to serviceAccount values for auto-generated docs - Document that automountServiceAccountToken only applies when create=true - Document that all pods share the same ServiceAccount - Regenerate README.md with helm-docs to include new values Signed-off-by: Mihai Criveti <crivetimihai@gmail.com>
