Development

Release

Push a tag with format vx.y.z, and let the CI build and publish

Testing

Manual testing can be done using docker compose, which will:

• Build the nodegraph-generator image
• Run a grafana server with anonymous / admin auth
• Provision grafana with the infinity datasource connected to nodegraph-generator's API
• Provision grafana with a service graph dashboard, and make it the home dashboard

For it to work, you need to port forward vmauth from the monitoring cluster

kubectl --context monitoring port-forward --namespace victoriametrics services/vmclusterlb-vmcluster 8427
