Release Notes

Update etcd-druid version in ref architectures

[kcp-ci-bot]

Hi @rose-krone. Thanks for your PR.

I'm waiting for a kcp-dev member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Thanks @rose-krone , did you test this? Are CRDs now auto-installed?

[rose-krone]

Yes I have installed the etcd druid chart in a empty cluster:

╰$ k get customresourcedefinitions.apiextensions.k8s.io | grep etcd

NOTES:
Etcd-Druid operator has been deployed to Namespace etcd-druid
Following resources has been deployed with name "etcd-druid":
 * Operator Deployment
 * Service
 * ServiceAccount
 * ClusterRole
 * ClusterRoleBinding

NOTE: Etcd cluster resource protection webhook has not been enabled. etcd-druid operator will
not be able to protect against any accidental deletion of resources that are created for an Etcd Cluster.
To read more about Etcd cluster resource protection see https://gardener.github.io/etcd-druid/deployment/configure-etcd-druid.html#etcd-components-webhook
To enable 'Etcd cluster resource protection webhook' you can set ".Values.operatorConfig.webhooks.etcdComponentProtection.enabled" (in 'charts/values.yaml' file) to true and re-install the chart.

Now that you have deployed etcd-druid operator you can create Etcd clusters by following the 'Getting Started Guide'.
See: https://gardener.github.io/etcd-druid/deployment/getting-started-locally/getting-started-locally.html#04-preparing-etcd-cr
