CI action to add `kglab` to DockerHub

[ceteri]

Let's add a CI action in GitHub to update a container image in DockerHub

• contact me (@ceteri) to get @DerwenAI credentials/secrets set up as needed
• update the .github/workflows/ci.yml file, see https://docs.github.com/en/actions/publishing-packages/publishing-docker-images
• add a build for the docker/Dockerfile container

This will help people who want to run the our notebook-based tutorial from DockerHub, i.e., what we use for the conference workshops.

@ceteri i would like to do this

[ceteri]

Many thanks @RishiKumarRay, that's great!

We have an account: https://hub.docker.com/u/derwenai/

Please let me know what you need. For next steps, is it best for us to set up GitHub secrets for the DockerHub credentials? We haven't needed to before, but I can do that.

[RishiKumarRay]

@ceteri for next steps can you please add the secrets in the repo , like the username and token for dockerhub and tell me the names you used so that i can add them in the workflow.

[ceteri]

Just added two repo secrets:

• DOCKER_USERNAME
• DOCKER_PASSWORD

There is a repo https://hub.docker.com/r/derwenai/kglab although I haven't loaded any images yet.

@ceteri I tried testing the github actions by using my dockerhub credentials as from fork your credentials are not accessible. So i see there is a image pushed which confirms that github actions is working correctly. So i will just change the credentials name with yours and it will work on yours too. You can check the image here https://hub.docker.com/repository/docker/rishiray/kglab

also you can check the github actions that i have written and tested here https://github.com/RishiKumarRay/kglab/runs/5490986719?check_suite_focus=true

let me know what you think and we can proceed accordingly.

[ceteri]

That's great @RishiKumarRay !

Next, how about, do you want to do a PR with the credential names switched to DerwenAI's, with the docker.yml tasks added into .github/workflows/ci.yml ? Then a PR merge will test it.

[RishiKumarRay]

@ceteri yeah sure i will raise a PR and you can test that and i am there to help

[RishiKumarRay]

@ceteri should i add the tasks in ci.yml or should i create a new file? how you want the things?

[ceteri]

Good point.

Best to have that as a separate file, and trigger on a release published: https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#release since we want to build/push the DockerHub images on each new release.

[RishiKumarRay]

@ceteri then in that case , you might be needed a tag so that whenever you tag the release then that release tag should be the tag of the image pushed instead of latest ?

[RishiKumarRay]

@ceteri i have raised A PR doing all the changes , make sure the credentials you have entered is correct and in docker password you have kept the token with proper permissions so that it can login and push the image. Also you can try creating a release with the tag whatever you want and you will notice that, tag will be the docker image tag wich will be pushed to the repo. Let me know if there is any error , i will try to help.

[ceteri]

Fantastic, that's all in place now:

• https://github.com/DerwenAI/kglab/runs/5500712142?check_suite_focus=true
• https://hub.docker.com/layers/derwenai/kglab/v0.5.1/images/sha256-091d00d508064754a3ebab8e3fc1bb25d5553b256c0edfe8c3bc30ca9f0992d3?context=explore

Many thanks @RishiKumarRay !!
