Private charm registry for Juju and Charmcraft
Summary
Private charm registry for Juju and Charmcraft
Description
Charm Registry is a private charm registry compatible with stock Juju and Charmcraft workflows. It exposes Charmhub-compatible APIs and includes an embedded OCI registry for image resources.
Install and configure
sudo snap install spellbook
sudo snap set spellbook oci.secret-key="$(openssl rand -hex 32)"
sudo snap start spellbook
The snap defaults to standalone mode using SQLite and filesystem storage under /var/snap/spellbook/common/data/.
Useful commands
snap services spellbook
sudo snap logs spellbook.charm-registry
snap get spellbook
sudo snap restart spellbook
Configure public URLs
sudo snap set spellbook public-api-url=http://registry.example.com:8080
sudo snap set spellbook public-storage-url=http://registry.example.com:8080
sudo snap set spellbook public-registry-url=https://registry.example.com:5000
For production, configure OIDC, admin identities, TLS, and durable storage such as PostgreSQL and S3-compatible object storage.
By default a self-signed certificate is generated, when using the registry with charmcraft or juju you'll have to add this certificate to the trust store:
sudo cp /var/snap/charm-registry/common/certs/oci.crt /usr/local/share/ca-certificates/charm-registry-oci.crt
sudo update-ca-certificates
Admin CLI
spellbook.charm-registryctl --url https://registry.example.com:8080 --token "<admin-token>" sync list
