How to add Dockerfile to a docker registry page?

Question

I successfully built a docker image starting from a different image and using a Dockerfile. I then did a docker push into my account in the docker registry, but I can't see the Dockerfile that I used in the registry page.

How do I add the Dockerfile I used to create the image into the registry page?

Answer 1

You'll need to do an automated build of your Docker image. Basically, you'll add the Dockerfile (and any related context) to a repo (GitHub, BitBucket, or your own), and Docker will build the image anytime it gets a webhook.

From the docs:

Automated Builds have several advantages:

• Users of your Automated Build can trust that the resulting image was built exactly as specified.

• The Dockerfile will be available to anyone with access to your repository on the Docker Hub registry.

• Because the process is automated, Automated Builds help to make sure that your repository is always up to date.
