To set up a charm project, create a directory for your charm, enter it, then run charmcraft init with the --profile flag followed by a suitable profile name (for machine charms: machine; for Kubernetes charms: kubernetes, simple, or flask-framework); that will create all the necessary files and even prepopulate them with useful content.
charmcraft init --profile <profile>
See sample session
$ mkdir my-flask-app-k8s
$ cd my-flask-app-k8s/
$ charmcraft init --profile flask-framework
Charmed operator package file and directory tree initialised.
Now edit the following package files to provide fundamental charm metadata
and other information:
charmcraft.yaml
src/charm.py
README.md
$ ls -R
.:
charmcraft.yaml requirements.txt src
./src:
charm.py
The command also allows you to not specify any profile (in that case you get the simple profile – a Kubernetes profile with lots of scaffolding, suitable for beginners) and has flags that you can use to specify a different directory to operate in, a charm name different from the name of the root directory, etc.
