Developing

Create and activate a virtualenv with the development requirements:

virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements-dev.txt

Code overview

Get familiarise with Charmed Operator Framework and Sunbeam documentation.

glance-k8s charm uses the ops_sunbeam library and extends OSBaseOperatorAPICharm from the library.

glance-k8s charm consumes database relation to connect to database, identity-service to register the service endpoints to keystone and ingress-internal/ingress-public relation to get exposed over internal and public networks.

Intended use case

glance-k8s charm deploys and configures OpenStack Image service on a kubernetes based environment. It should be possible to use local storage or ceph based storage as backend.

Testing

The Python operator framework includes a very nice harness for testing operator behaviour without full deployment. Run tests using command:

tox -e py3

Deployment

This project uses tox for building and managing. To build the charm run:

tox -e build

To deploy the local test instance:

juju deploy ./glance-k8s_ubuntu-20.04-amd64.charm --trust --resource glance-image=ghcr.io/canonical/glance-api:2023.2
