Helm chart for deploying Grafana rollout-operator to Kubernetes.

rollout-operator

Grafana rollout-operator

Requirements

Kubernetes: ^1.10.0-0

Installation

This section describes various use cases for installation, upgrade and migration from different systems and versions.

Preparation

These are the common tasks to perform before any of the use cases.

# Add the repository
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update

Installation of Grafana Rollout Operator

helm install  -n <namespace> <release> grafana/rollout-operator

The Grafana rollout-operator should be installed in the same namespace as the statefulsets it is operating upon. It is not a highly available application and runs as a single pod.

Upgrade of Grafana Rollout Operator

Starting with v0.33.0 of the rollout-operator chart, the rollout-operator webhooks are enabled. See https://github.com/grafana/rollout-operator/#webhooks.

Before upgrading to this version, make sure that the CustomResourceDefinitions (CRDs) in the crds directory are applied to your cluster.

Manually applying these CRDs is only required if upgrading from a chart <= v0.32.0.
