- HA using Patroni
- Full backups and restores are supported when using any S3-compatible storage
- TLS support (using “tls-certificates” operator)
- DB access outside of Juju using “data-integrator”
- Data import using standard tools e.g. “PostgreSQL Data Injector”
- Documentation:
| Charm | Version | Charm channel | Documentation | License |
|---|---|---|---|---|
| PostgreSQL K8s | 14.7 | 14/stable (r73) | Tutorial, Readme, Contributing | Apache 2.0 |
What is inside the charms:
- Charmed PostgreSQL K8s charm ships the latest PostgreSQL “14.7-0ubuntu0.22.04.1”
- K8s charms based on our ROCK OCI (Ubuntu LTS “22.04” - ubuntu:22.04-based)
- Principal charms supports the latest LTS series “22.04” only.
- Subordinate charms support LTS “22.04” and “20.04” only.
Technical notes:
Compatibility with legacy charms:
- New PostgreSQL charm is also a juju-interface compatible replacement for legacy PostgreSQL charms (using legacy interface “pgsql”, via endpoints “db” and “db-admin”). However, it is highly recommended to migrate to the modern interface “postgresql_client” (endpoint “database”).
Please contact us, see details below, if you are considering migrating from other “legacy” charms not mentioned above. Additionally:
- Tracks description:
- Charm PostgreSQL K8s charm follows the SNAP track “14” (through repackaed ROCK/OCI image).
- No “latest” track in use (no surprises in tracking “latest/stable”)!
- Charmed PostgreSQL K8s charms provide legacy charm through “latest/stable”.
- Charm lifecycle flowchart diagrams: PostgreSQL.
- Modern interfaces are well described in “Interfaces catalogue” and implemented by ‘data-platform-libs’.
- Known limitation: PostgreSQL extensions are not yet supported.
