Update docker container when new image is getting released

Question

Except watchtower what other tools we have in order to update containers when a new image is getting released?

Watchtower seems good but t does not support yet private registry other than docker hub, ie I would like to use gitlab registry.

Answer 1

This is discussed in watchover issue 3, with reference to PR 13 which allows for pulling private images (on Docker Hub though).

You need to apply PR 26 in order to fix support for private docker registry authentication. This is where the latest effort to support private images is being developed, as there is no other alternative project that I could find.
