* Introduce crds directory for compatibility with Helm v3 This commit introduce a crd directory for the helm chart which has all custom resource definitions. The files in the crd directory is plain YAML. The crds got the label `app.kubernetes.io/name: postgres-operator` and removes all the templating. Helm v3 ignores the objects from the `templates` directory which have a `crd-install` hook. This commit addes templates/crds.yaml which generates YAMLs for CRDs. The hooks from these CRDs are detected by Helm v2 as well as v3. Helm v2 executes the hook and Helm v3 ignores the hook (YAML files are not applied) The approach is inspired by the prometheus-operator chart helm/charts@89b233eef6
Postgres Operator
The Postgres Operator enables highly-available PostgreSQL clusters on Kubernetes (K8s) powered by Patroni. It is configured only through manifests to ease integration into automated CI/CD pipelines with no access to Kubernetes directly.
Operator features
- Rolling updates on Postgres cluster changes
- Volume resize without Pod restarts
- Cloning Postgres clusters
- Logical Backups to S3 Bucket
- Standby cluster from S3 WAL archive
- Configurable for non-cloud environments
- UI to create and edit Postgres cluster manifests
PostgreSQL features
- Supports PostgreSQL 9.6+
- Streaming replication cluster via Patroni
- Point-In-Time-Recovery with pg_basebackup / WAL-E via Spilo
- Preload libraries: bg_mon, pg_stat_statements, pgextwlist, pg_auth_mon
- Incl. popular Postgres extensions such as decoderbufs, hypopg, pg_cron, pg_partman, pg_stat_kcache, pgq, plpgsql_check, postgis, set_user and timescaledb
The Postgres Operator has been developed at Zalando and is being used in production for over two years.
