Amazing Cache Busting Trick

If you're building from GitHub repos that you want to trigger rebuilds upon any change by busting the Docker build cache you can put this in your Dockerfile:

# Cache Bust upon new commits
ADD https://api.github.com/repos/HariSekhon/DevOps-Bash-tools/git/refs/heads/master /.git-hashref

I used this in my HariSekhon/Dockerfiles repo for several of my major GitHub repos like DevOps-Bash-tools and DevOps-Python-tools.

Python - Create Smaller Docker Images Using the Builder Pattern

Use the Python builder pattern to make small Python docker images, see this Medium article.

The code for this is in the Dockerfile template above.
