Uninstall Rancher Turtles

This gives an overview of Rancher Turtles uninstallation process.

caution

When installing Rancher Turtles in your Rancher environment, by default, Rancher Turtles enables the Cluster API Operator cleanup. This includes cleaning up Cluster API Operator specific webhooks and deployments that otherwise cause issues with Rancher provisioning.

To simplify uninstalling Rancher Turtles (via Rancher Manager or helm command), the official Rancher Turtles Helm chart includes a post-delete hook that applies these changes, making it transparent to the end user:

  • Delete the mutating-webhook-configuration and validating-webhook-configuration webhooks that are no longer needed.
  • Delete the CAPI deployments that are no longer needed.

To uninstall the Rancher Turtles Extension use the following helm command:

helm uninstall -n rancher-turtles-system rancher-turtles --cascade foreground --wait

This may take a few minutes to complete.

note

Remember that, if you use a different name for the installation or a different namespace, you may need to customize the command for your specific configuration.

Once uninstalled, Rancher's embedded-cluster-api feature must be re-enabled:

  1. Create a feature.yaml file, with embedded-cluster-api set to true:
feature.yaml
apiVersion: management.cattle.io/v3
kind: Feature
metadata:
  name: embedded-cluster-api
spec:
  value: true
  1. Use kubectl to apply the feature.yaml file to the cluster:
kubectl apply -f feature.yaml
