.env.example outdated
There are a couple of env vars that still target CKAN 2.10 (e.g SOLR_IMAGE_VERSION=2.10-solr9). These should be updated to 2.11.
CKAN_VERSION is also outdated but that doesn't look like it used, so maybe it can be removed.
CKAN___BEAKER__SESSION__SECRET should be replaced by SECRET_KEY
Would be good to do a quick review to see if something else needs to be updated
The CKAN value in .env has no effect n docker images, it is hardcoded and changes at every version: https://github.com/ckan/ckan-docker/blob/master/ckan/Dockerfile#L1
There is a lot of confusion regarding ckan-docker: not release nor branche or tag and ckan docker base image: The CKAN documentation recommends using XLoader instead of DataPusher for new deployments, but there are no official Docker images that ship with XLoader configured by default for 2.11. As a result, the official images still come with DataPusher, which is explicitly labeled as legacy and “the worst option” in the docs. This is confusing for new users who expect the recommended approach to be reflected in the official images.^^ https://github.com/ckan/ckan-docker-base/issues/134
