25.04.0 release is missing on docker hub

[thopp-tudelft]

Context

releases usually come with a published docker image on docker hub, this is mentioned in the release notes.
the release says to run: export DOCKER_TAG=="25.04.0" && ./start-docker.sh

• as a side note: this script doesn't exist, I'd replace it with a link to the documentation or export DOCKER_TAG=="25.04.0" && cd tools/hosting && docker compose up -d

Expected Behavior

docker pull scalableminds/webknossos:25.04.0 will pull the current release from docker hub

Current Behavior

instead we have an error: manifest for scalableminds/webknossos:25.04.0 not found: manifest unknown: manifest unknown
this is because the release does not exist and can't be found in the tags on docker hub: https://hub.docker.com/r/scalableminds/webknossos/tags?name=25.04

Steps to Reproduce the bug

• Cannot reproduce the bug anymore / needs deeper investigation.

1. docker pull scalableminds/webknossos:25.04.0

Your Environment for bug

• self hosted webknossos instance on docker

Thanks for notifying us about this! We recently switched from CircleCI to Github Actions and it looks like the image was not pushed properly with our adapted CI scripts. We’ll have a look!

which workflow is supposed to push on release? none of your workflow files have a "on:" "push:" "tags:" section.

This was added now in #8577 and the new release 25.05.0 seems to have been pushed to dockerhub properly. https://hub.docker.com/layers/scalableminds/webknossos/25.05.0/images/sha256-ba439d60881686742965a1b1d783cf7e1a91392a538cccfd426d39ffdbddaaa0
