- [X] Have you signed the [CLA](http://www.ubuntu.com/legal/contributors/)? ----- Using the new `python3.11-venv` slice to reduce the image of the generated rock when base is `bare` using `flask-framework` and `django-framework` extensions. How to test: Install a build of rockcraft using this branch, you need to have `docker` installed too ```bash git pull https://github.com/canonical/sample-flask.git cd sample-flask rockcraft init --profile flask-framework # Edit the required fields in rockcraft.yaml # 1. We ensure that when using ubuntu@22.04 base it still works rockcraft pack rockcraft.skopeo copy --insecure-policy oci-archive:sample-flask_0.1_amd64.rock docker-daemon:sample-flask:ubuntu docker run -d --name flask-ubuntu -p 8000:8000 sample-flask:ubuntu curl localhost:8000 # Should return <h1>Hello</h1> docker exec -ti flask-ubuntu bash /bin/python3 --version # Should return "Python 3.10.12" exit docker stop flask-ubuntu # Edit rockcraft.yaml, change base to "bare" and add "build-base: ubuntu@22.04" rockcraft clean rockcraft pack rockcraft.skopeo copy --insecure-policy oci-archive:sample-flask_0.1_amd64.rock docker-daemon:sample-flask:bare docker run -d --name flask-bare -p 8000:8000 sample-flask:bare curl localhost:8000 # Should return <h1>Hello</h1> docker exec -ti flask-bare bash /bin/python3 --version # Should return "Python 3.10.12" exit docker stop flask-bare ``` You can also test using the tutorial (follow the chiseling part of the tutorial): https://documentation.ubuntu.com/rockcraft/en/latest/tutorials/getting-started-with-flask/
