Helm installation |
grafana-operator for Kubernetes to manage Grafana instances and grafana resources.
This is a OCI helm chart, helm started support OCI in version 3.8.0.
helm upgrade -i grafana-operator oci://ghcr.io/grafana/helm-charts/grafana-operator --version v5.8.1Sadly helm OCI charts currently don't support searching for available versions of a helm oci registry.
Helm does not provide functionality to update custom resource definitions. This can result in the operator misbehaving when a release contains updates to the custom resource definitions. To avoid issues due to outdated or missing definitions, run the following command before updating an existing installation:
kubectl apply --server-side --force-conflicts -f https://github.com/grafana/grafana-operator/releases/download/v5.8.1/crds.yamlThe --server-side and --force-conflict flags are required to avoid running into issues with the kubectl.kubernetes.io/last-applied-configuration annotation.
By using server side apply, this annotation is not considered. --force-conflict allows kubectl to modify fields previously managed by helm.
For general and helm specific development instructions please read the CONTRIBUTING.md
The chart won't support any configuration of grafana instances or similar. It's only meant to be used to install the grafana-operator. Deployments of grafana instances using the CRs is supposed to be done outside of the chart.
Currently the plan is not to support networkpolicy. The operators support os diverse configuration that you have to support all options. It's easier to just manage this configuration outside of the operator.
