The Postgres Operator delivers an easy to run highly-available PostgreSQL clusters on Kubernetes (K8s) powered by Patroni. It is configured only through Postgres manifests (CRDs) to ease integration into automated CI/CD pipelines with no access to Kubernetes API directly, promoting infrastructure as code vs manual operations.
The Postgres Operator has been developed at Zalando and is being used in production for over three years.
If you are new to the operator, you can skip this and just start using the Postgres operator as is, Postgres 13 is ready to go.
The Postgres operator supports Postgres 13 with the new Spilo Image that includes also the recent Patroni version to support PG13 settings. More work on optimizing restarts and rolling upgrades is pending.
If you are already using the Postgres operator in older version with a Spilo 12 Docker image you need to be aware of the changes for the backup path. We introduce the major version into the backup path to smoothen the major version upgrade that is now supported manually.
The new operator configuration can set a compatibility flag enable_spilo_wal_path_compat to make Spilo look for wal segments in the current path but also old format paths. This comes at potential performance costs and should be disabled after a few days.
The new Spilo 13 image is: registry.opensource.zalan.do/acid/spilo-13:2.0-p2
The last Spilo 12 image is: registry.opensource.zalan.do/acid/spilo-12:1.6-p5
