Self-host alternative to Docker Hub?

I've successfully self-hosted everything until I realised I'm getting
billed £6 a month by Docker to allow me to automatically build images
based on pushed code to GitHub. I'd like to have a self-hosted version
of Docker Hub which allows me to automatically build images when code
is pushed to GitHub, view the progress of the build/logs, host the
image privately, be able to pull the image down via portainer.

​

I have seen Harbor but - correct me if I'm wrong - I do not think it
automatically builds images based on GitHub webhooks?

Github Action.

[https://github.com/docker/build-push-
action](https://github.com/docker/build-push-action)

[https://docs.docker.com/build/ci/github-
actions/](https://docs.docker.com/build/ci/github-actions/)

Doesn’t have a UI and I do not want to have to create an action
manually on each repository. I’d like a system (which is what I do on
Docker Hub) where I select a GitHub account and repository to use to
create an image out of.

I know I’m being picky - however if I’m going to replace Docker Hub -
I want to do it right.

Org Webhooks.

[https://docs.github.com/en/webhooks/types-of-
webhooks](https://docs.github.com/en/webhooks/types-of-webhooks)

Then, a master repo to have builder action to build and push docker
image when webhook triggers.

Also, r/devops would like to hear more about why CI/CD not being a
system...

How about a self hosted Docker Registry (the image is called registry)
and a Build Server like Jenkins?

Getting Jenkins to run in a Docker Container itself needs the Jenkins
and a DinD (Docker in Docker) Container. You will need to read a
little into it, but it is possible.

I did that some time ago but I switched to GH Actions by now. No need
to maintain a Build Server and if my server breaks the builds could
run immediately after getting the registry back up. So this is
definitely my recommendation.

Just as a side note: I think Sonatype Nexus has a Docker Registry too
but I didn't come around to try that yet.

That’s a really good idea actually thank you. I have used ‘registry’
in the past just obviously didn’t have the build part to the pipeline.

I’ll have a look at both! Thank you!
