Why does Docker have builds and not GitHub tags are pushed?

[williamdes]

@thomascube I noticed no new git tags are pushed but that the image gets updated.
What is the new process?

[thomascube]

The github actions are not set up to create tags. Previously, tagging (and thus releasing) was a manual process which triggered builds on Docker Hub. Because of the new automation with Github actions, tags are no longer needed. That saying, suggestions how to extend our actions to create tags again are welcome.

Okay, thanks
I think having tags is good to know from what was thrown the workflow

We could consider to create tags for each version again but some questions come to my mind:

• How to build new images if we make changes to the Dockerfile but the Roundcube version is unchanged?
  • Moving the Git tag?
  • Different versioning schema for Docker images?
• Same question for periodic updates of the base image (php) without Roundcube version changes.
• How to do auto-update as we currently do with the update.sh cron job?
  • Can github actions create tags?

Trigger the same tag once more ?

  * Moving the Git tag?

This one is for me a bad option, avoid moving git tags.

Using git tags is quite easy and will do the trick
You can automate all this
Look at how I derived GitHub caching to do this here: https://github.com/sudo-bot/docker-phpmyadmin-snapshots/blob/main/.github/workflows/cron.yml

And when a release is published, then it is built: https://github.com/sudo-bot/docker-phpmyadmin-snapshots/blob/main/.github/workflows/publish.yml#L8

I don't quite understand this issue. Roundcubemail uses git-tags only for releases, if I am not mistaken. And these releases are picked up by update.sh. And the images are tagged with the version numbers, too.

Can someone explain what's missing?
