For optimization purposes operator was creating a cache map to remember if service accounts and role binding was deployed to a namespace. This could lead to a problem, when a namespace was deleted, since this cache was not synchronized. For the sake of correctness remove the cache, and check every time if required service account and rbac is present. In the normal case this introduces an overhead of two API calls per an event (one to get a service accounts, one to get a role binding), which should not be a problem, unless proven otherwise.
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.
