Automate Docker Hub Builds with GitHub

Automating builds of docker containers on hub.docker.com is a fairly straightforward process, assuming you have a repository on GitHub containing a Dockerfile.

Here is an example repository.

Setting Up Automated Builds

First, on Docker Hub, choose the “Create” drop-down and select “Create an Automated Build”.

If you haven’t linked a GitHub or BitBucket account yet, you will be prompted to do so. Select “Link Accounts” and follow the prompts.

Select “Create an Automated Build with < Provider >”.

From there, it’s simply a matter of selecting your repository containing a Dockerfile.

Pulling the Container

Once the automated build is setup, pulling the container is as simple as executing:

docker pull <username>/<repository>

Any time you push changes to the linked GitHub repository, Docker Hub will automatically rebuild the container image.
