* Improving end 2 end tests, especially speed of execution and error, by implementing proper eventual asserts and timeouts. * Add documentation for running individual tests * Fixed String encoding in Patorni state check and error case * Printing config as multi log line entity, makes it readable and grepable on startup * Cosmetic changes to logs. Removed quotes from diff. Move all object diffs to text diff. Enabled padding for log level. * Mount script with tools for easy logaccess and watching objects. * Set proper update strategy for Postgres operator deployment. * Move long running test to end. Move pooler test to new functions. * Remove quote from valid K8s identifiers.
Postgres Operator
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.
Operator features
- Rolling updates on Postgres cluster changes, incl. quick minor version updates
- Live volume resize without pod restarts (AWS EBS, others pending)
- Database connection pooler with PGBouncer
- Restore and cloning Postgres clusters (incl. major version upgrade)
- Additionally logical backups to S3 bucket can be configured
- Standby cluster from S3 WAL archive
- Configurable for non-cloud environments
- Basic credential and user management on K8s, eases application deployments
- UI to create and edit Postgres cluster manifests
- Works well on Amazon AWS, Google Cloud, OpenShift and locally on Kind
PostgreSQL features
- Supports PostgreSQL 12, starting from 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.
