Manage a 12-factor app charm¶
These guides walk you through all ways you can manage 12-factor app charms, from initialization to usage.
Extensions add customized elements to a charm for specific web app frameworks. While the overall basic logic is the same as managing a charm, the following guides are about the 12-factor app charm workflow.
Initialization¶
You will need a rock for your 12-factor app charm. Prepare a 12-factor app rock with Rockcraft.
Once you have a rock, use charmcraft init
and specify the relevant profile:
charmcraft init --profile django-framework
charmcraft init --profile expressjs-framework
charmcraft init --profile fastapi-framework
charmcraft init --profile flask-framework
charmcraft init --profile go-framework
Charmcraft automatically creates a charmcraft.yaml
project file, a
requirements.txt
file and source code for the charm in your current directory. You
will need to check the project file and README.md
to verify that the charm’s name
and description are correct.
Configuration¶
Once your 12-factor app charm has been set up, you can customize many aspects of it using Juju.
Integration¶
Once deployed, your 12-factor app can be integrated into nearly anything in the Juju ecosystem.
Usage¶
Now that you’ve initialized and configured your 12-factor app charm, you’re ready to use it.
