Base images for Python projects deployed on Divio Cloud.

Locally build an image

To locally build an image, run the following command:

./build.py --repo divio/base --tag 0.00-py3.6-alpine3.7 build

Check ./build.py --help for additional information.

Test all images

You can build and test all images locally by running:

ls -d py* | xargs -I '{}' ./build.py --repo divio/base --target=prod --tag test-{} build
ls -d py* | xargs -I '{}' ./build.py --repo divio/base --target=dev --tag test-{} build
ls -d py* | xargs -I '{}' ./build.py --repo divio/base --tag test-{} test

Release process

Tag commits with the desired Docker image tag, in the form:

git tag <version>-<flavour>

For your convenience, the release.py script can be used to streamline the tagging operations:

./release.py versions --next=minor py*

The command outputs the new tags which would be applied to the repository. Once asserted the result is correct, re-run the command with the --tag flag:

./release.py versions --next=minor --tag py*

Then push the tags to GitHub to trigger an automatic build on Docker Cloud:

git push --tags github

Please note that GitHub will not trigger webhooks when pushing more than 2 tags at the same time. When more than two images are updated, push using:

./release.py versions --push=github --last py*

Adding a new base image

Add a directory at the root containing an appropriate Dockerfile. The image will be tagged as `divio/base:<version>-<directory-name>.
