ovn-central-k8s

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.

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

ovn-central-k8s charm consumes certificates to get generated certificates from vault and provides ovsdb-cms relation to provide ovn-central endpoints for external services to connect to.

ovn-central-k8s starts northd, ovsdb-sb-server, ovsdb-nb-server services by creating separate pebble handlers for each service.

Intended use case

ovn-central-k8s charm deploys and configures OVN Central services on a kubernetes based environment.

Testing

The Python operator framework includes a very nice harness for testing operator behaviour without full deployment. Just run_tests:

./run_tests

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 ./ovn-central-k8s_ubuntu-20.04-amd64.charm --trust --resource ovn-northd-image=registry.jujucharms.com/charm/kau2b145zhaeuj5ly4w4m30qiq8qzspf93tnd/ovn-northd-image ovn-nb-db-server-image=registry.jujucharms.com/charm/kau2b145zhaeuj5ly4w4m30qiq8qzspf93tnd/ovn-nb-db-server-image ovn-sb-db-server-image=registry.jujucharms.com/charm/kau2b145zhaeuj5ly4w4m30qiq8qzspf93tnd/ovn-sb-db-server-image
