If the install procedure for Wallaroo goes awry, one option is to uninstall the incomplete Wallaroo installation and start again. The following procedure will remove Wallaroo from a Kubernetes cluster.

1. Use the following bash script or run the commands individually. Warning: If the selector is incorrect or missing from the kubectl command, the cluster could be damaged beyond repair.

   #!/bin/bash
   kubectl delete ns wallaroo && kubectl delete clusterroles,clusterrolebindings,storageclass --selector app.kubernetes.io/part-of=wallaroo
   

2. Clear any Wallaroo pipelines that were previously deployed and not undeployed via the following command. This will delete any namespaces created during the pipeline deployment process.

   kubectl delete ns -l wallaroo-managed=true
   

3. Once complete, the kubectl get namespaces will return only the default namespaces:

   ❯ kubectl get namespaces
   NAME              STATUS   AGE
   default           Active   3h47m
   kube-node-lease   Active   3h47m
   kube-public       Active   3h47m
   kube-system       Active   3h47m
   

Wallaroo can now be reinstalled into this environment.
