|
The Postgres Operator delivers an easy to run highly-available [PostgreSQL](https://www.postgresql.org/)
|
|
clusters on Kubernetes (K8s) powered by [Patroni](https://github.com/zalando/spilo).
|
|
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.
|
|
|
|

* Database connection pooler with PGBouncer
|
|
* Restore and cloning Postgres clusters (incl. major version upgrade)
