TimescaleDB Support

[sbyrne-teck]

Hi,

Is the timescaledb-ha image catalog option officially supported by CNPG as the recommended approach for using timescale?

The reason I ask is because it is not mentioned in the official docs and it is not mentioned in the README of the cluster chart. If not, is it recommended to use the cloudnativepg image as a base and add the timescale db extension in?

Thanks

Hi @sbyrne-teck! I'm Dosu and I’m helping the charts team.

The timescaledb-ha image catalog option is not officially supported or recommended by CloudNativePG. It's not mentioned in the official documentation or the cluster chart README, and the only officially maintained images are those published by the CloudNativePG community (like ghcr.io/cloudnative-pg/postgresql and PostGIS) source.

While some users have managed to use the timescaledb-ha image with CNPG via the ImageCatalog feature, this is considered a workaround and not an officially documented or supported path. There are known issues with image tag compliance and operational errors when using timescaledb-ha images in this way source.

The recommended approach is to build your own custom image based on the official CloudNativePG image and install the TimescaleDB extension yourself. This method is supported and aligns with community and maintainer guidance source. There are blog posts and documentation on how to create custom images for CNPG if you need a starting point source.

If you go this route, keep in mind that support boundaries are clear: the community supports the official images, but if you add custom extensions like TimescaleDB, you are responsible for maintaining and troubleshooting those additions source.

To reply, just mention @dosu.
