etcd cluster -configuration and management. - -__DISCLAIMER:__ While this chart has been well-tested, the etcd-operator is still currently in beta. -Current project status is available [here](https://github.com/coreos/etcd-operator). - -## Introduction - -This chart bootstraps an etcd-operator and allows the deployment of etcd-cluster(s). - -## Official Documentation - -Official project documentation found [here](https://github.com/coreos/etcd-operator) - -## Prerequisites - -- Kubernetes 1.4+ with Beta APIs enabled -- __Suggested:__ PV provisioner support in the underlying infrastructure to support backups - -## Installing the Chart - -To install the chart with the release name `my-release`: - -```bash -$ helm install stable/etcd-operator --name my-release -``` - -__Note__: If you set `cluster.enabled` on install, it will have no effect. -Before you create an etcd cluster, the TPR must be installed by the operator, so this option is ignored during helm installs, but can be used in upgrades. - -## Uninstalling the Chart - -To uninstall/delete the `my-release` deployment: - -```bash -$ helm delete my-release -``` - -The command removes all the Kubernetes components EXCEPT the persistent volume. - -## Updating -Updating the TPR resource will not result in the cluster being update until `kubectl apply` for -TPRs is fixed see [kubernetes/issues/29542](https://github.com/kubernetes/kubernetes/issues/29542) -Work around options are documented [here](https://github.com/coreos/etcd-operator#resize-an-etcd-cluster) - -##

To disable RBAC do the following: - -```console -$ helm install --name my-release stable/etcd-operator --set rbac.create=false -``` - -### Changing RBAC manifest apiVersion - -By default the RBAC resources are generated with the "v1beta1" apiVersion. To use "v1alpha1" do the following: - -```console -$ helm install --name my-release stable/etcd-operator --set rbac.install=true,rbac.apiVersion=v1alpha1 -``` |
