Container Images

In the previous section, the information about the container registry can be found. With the registry in place, we can now build and push the container images. The Example Voting App, consists of 5 container, from which 3 need to be built. The code can be found in the following folder:

• result-app
• vote-app
• worker

These three applications, come already with the Dockerfiles. The missing piece is to provide the GitHub Action scripts to build and push the images. These scripts can be found here:

• docker-build-result-app.yml
• docker-build-vote-app.yml
• docker-build-worker.yml

caution

Having three files, one for each image, isn't a good practice. This needs to be changed and combined into one file, with variables for each folder.
