Charmcraft
Charmcraft is the command-line tool for initializing, packaging, and publishing charms, the software operators used by Juju. With Charmcraft, you can bypass the boilerplate steps of crafting a charm and focus on what matters — building scalable, configurable, and easy-to-deploy applications for Juju.
Basic usage
Charmcraft provides commands to streamline every step of the charm development process, from initializing your charm project to releasing it on Charmhub.
In your project's root directory, initialize your charm project with basic template content by running:
charmcraft init
Once you've configured your project to suit the needs of the application you're charming, build the charm by running:
charmcraft pack
If you're ready to distribute your charm, you can register its name on Charmhub with:
charmcraft register
Upload your charm and any subsequent revisions to Charmhub with:
charmcraft upload
Installation
Charmcraft is available on all major Linux distributions and macOS.
The recommended way to install Charmcraft on Linux systems is through its snap.
sudo snap install charmcraft --classic
