How to Uninstall Wallaroo

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. Remove all Kubernetes namespaces with the kubectl delete namespaces {list of namespaces}command except the following : default, kube* (any namespaces with kube before it).

   For example, in the following environment wallaroo, model1 and model2 would be deleted with the following:

     -> kubectl get namespaces
       NAME			    STATUS        AGE
       default		        Active        7d4h
       kube-node-lease	    Active		    7d4h
       kube-public		    Active		    7d4h
       model1               Active         4h23m
       model2               Active         4h23m
       wallaroo             Active         3d6h
   
       kubectl delete namespaces wallaroo model1 model2
   

2. Use the following bash script or run the commands individually:

   #!/bin/bash
   
   kubectl delete namespace minio-operator
   kubectl delete clusterrole/minio-operator-role
   kubectl delete clusterrole/console-sa-role
   kubectl delete clusterrolebinding/minio-operator-binding
   kubectl delete clusterrolebinding/console-sa-binding
   kubectl delete crd/modelconfigs.wallaroo.ai
   kubectl delete crd/tenants.minio.min.io
   

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.
