Docker build images workflow in Python
Since docker hub stopped building images for free accounts, I’ve been looking for another way to do it. I could have used simple shell scripts, but that’s too simple and not fun. So I found a way to continue playing with Python by using a library I heard about a few weeks ago.
Using Spotify luigi and docker-py libraries to build docker images
Remember, it’s just a way to explore and use library like Spotify luigi or docker-py.
Docker images structure
[image]/[sub]/Dockerfile
Sub directory is optional.
[image]/Dockerfile
Run tasks command
Build PHP 8.1 image, and push it to Docker repository.
# Fpm image
python -m luigi --module task_php_image Push --version 8.1 --sub fpm --date '2021-12-18'
# Dev image
python -m luigi --module task_php_image Push --version 8.1 -sub dev --date '2021-12-18'
# Cli iaage
python -m luigi --module task_php_image Push --version 8.1 -sub cli --date '2021-12-18'
Build the Python 3.10 image, and push it to Docker repository.
python -m luigi --module task_python_image Push --version 3.10 --date '2021-12-18'
Push task has a dependency task, the Build task. Before running the Push task luigi executes the Push task.
