Container Image RequirementsFeedback
The Cloud Native PostgreSQL operator for Kubernetes is designed to work with any compatible container image of PostgreSQL that complies with the following requirements:
- PostgreSQL 10+ executables that must be in the path:
- Barman Cloud executables that must be in the path:
- Sensible locale settings
No entry point and/or command is required in the image definition, as Cloud Native PostgreSQL overrides it with its instance manager.
Application Container Images will be used by Cloud Native PostgreSQL in a Primary with multiple/optional Hot Standby Servers Architecture only.
EnterpriseDB provides and supports public container images for Cloud Native PostgreSQL and publishes them on Quay.io.
While the image name can be anything valid for Docker, the Cloud Native PostgreSQL operator relies on the image tag to detect the Postgres major version carried out by the image.
The image tag must start with a valid PostgreSQL major version number (e.g. 9.6 or 12) optionally followed by a dot and the patch level.
The prefix can be followed by any valid character combination that is valid and accepted in a Docker tag, preceded by a dot, an underscore, or a minus sign.
Examples of accepted image tags:
latest is not considered a valid tag for the image.
