Publish a charm to charmhub#

Publishing to charmhub is straightforward: all you need to do is follow the register-upload-release workflow.

Note: in headless environments (e.g. multipass), use this:

dbus-run-session -- bash -c "echo password | gnome-keyring-daemon --unlock; charmcraft <args>"

Register a new charm's name under your account#

charmcraft names
charmcraft register karma-k8s

Pack and upload charm#

charmcraft pack
charmcraft upload karma-k8s_ubuntu-20.04-amd64.charm
charmcraft revisions karam-k8s

Upload resource (e.g. OCI image)#

charmcraft resources karma-k8s
charmcraft status karma-k8s

docker pull ghcr.io/prymitive/karma:v0.92
IMAGE_ID=$(docker images -q ghcr.io/prymitive/karma:v0.92)
charmcraft upload-resource karma-k8s karma-image --image=$IMAGE_ID
charmcraft resource-revisions karma-k8s karma-image

IMAGE="docker://ghcr.io/prymitive/karma:v0.114"
DIGEST=$(skopeo inspect $IMAGE | jq -r '.Digest')

CHARM="karma-k8s"
RESOURCE="karma-image"
charmcraft upload-resource $CHARM $RESOURCE --image=$DIGEST

charmcraft release karma-k8s --channel=edge --revision=1 --resource=karma-image:1
charmcraft status karma-k8s

charmcraft status lma-light

Publish a library#

charmcraft list-lib alertmanager-k8s
