This exercise is building up on exercise 1.4 (Github Actions).
The goal of this exercise is to push your previously built Docker image to the public Docker hub: hub.docker.com
Performing this step is absolutely necessary for most of the following exercises.
The goal of this exercise is to extend your your Github Actions to:
- Use the Github Action provided by Docker (see documentation here)
- Push your image with a unique tag to hub.docker.com (use the
GITHUB_SHA
environment variable)
