Once you have built your charm, you should publish it to Charmhub. This section will guide you through the process.
Build your charm
Before your charm can be published, it needs to be built. The build process will fetch any dependencies you’ve specified in your
requirements.txt and package them up with your charm code in a
$ charmcraft pack Done, charm left in 'hello-operator.charm'
.charm file is just a zip file, and can be unzipped and examined as such.
Register a name
Before you can interact with Charmhub using
charmcraft you’ll need to login:
$ charmcraft login Opening an authorization web page in your browser; if it does not open, please open this URL: https://api.staging.jujucharms.com/identity/login?did=<id> Login successful.
charmcraft session will expire automatically, but you’ll be prompted to re-authenticate automatically next time you try to access a feature that requires interaction with Charmhub
If you’re publishing your charm for the first time, you’ll need to register the name to your account:
$ charmcraft register my-awesome-charm Congrats! You are now the publisher of 'my-awesome-charm'
You can check the charm names registered to your account at any time:
$ charmcraft names Name Visibility Status # ... my-awesome-charm public registered # ...
Upload and Release
The charm is now ready to be uploaded, which is achieved by invoking
charmcraft upload and passing the filename of the built charm:
charmcraft upload my-awesome-charm.charm Revision 1 of my-awesome-charm created
Every time a new binary is uploaded for a charm, a new revision is created on Charmhub. We can verify its current status easily:
$ charmcraft revisions my-awesome-charm Revision Version Created at Status 1 0.1 2020-07-23 approved
Uploaded charms are not automatically released and made available for download. Once a charm is uploaded, it must be released into a channel before it can be consumed:
$ charmcraft release my-awesome-charm --revision=1 --channel=beta Revision 1 of charm 'my-awesome-charm' released to beta
Note that Charmhub uses information from the
stable channel to populate the information on a charm’s homepage by default.
Finally, we can see the overall status:
$ charmcraft status my-awesome-charm Track Channel Version Revision latest stable - - candidate - - beta 0.1 1 edge ↑ ↑
If your charm is designed to work on Kubernetes, or otherwise requires the use of Charm Resources, there are additional steps required to upload the resources and attach them to a release. Read more in the Publishing Resources section.
