Uninstall Everest¶

You can run the commands below to remove all Everest resources including:

All Kubernetes objects created by Everest
All downloaded binaries and files like everestctl.

Warning

Uninstalling Everest will remove all database clusters and associated data from the Kubernetes cluster, including backups!

Before proceeding with Custom Resource Definitions (CRD) cleanup, check that any custom resources linked with CRDs are removed. This is a crucial step because deleting CRDs can potentially cause issues with any custom resources that depend on those definitions within the cluster.

To uninstall Everest:

Uninstall Everest:
```
everestctl uninstall
```

Remove ALL created database clusters:

kubectl delete db --all -n percona-everest

Remove ALL backups:

kubectl -n percona-everest delete job --all
kubectl -n percona-everest delete pxc-backup --all
kubectl -n percona-everest delete psmdb-backup --all
kubectl -n percona-everest delete pg-backup --all
kubectl -n percona-everest delete pod --all

Remove ALL PVCs:

kubectl delete pvc --all -n percona-everest

List CSVs and remove those with a “percona” and “everest” prefix, or remove ALL operators:

kubectl delete sub --all -n percona-everest
kubectl delete ip --all -n percona-everest
kubectl delete csv --all -n percona-everest

List ALL CRDs that will be removed using the following command. Keep in mind that this command will exclusively list CRDs linked to Everest and skip any CRDs associated with standalone Percona Operators. This distinction is crucial because if there are instances of standalone Percona Operators existing within any namespace in your Kubernetes environment, you should avoid inadvertently deleting their CRDs.

kubectl get crd -l="operators.coreos.com/percona-server-mongodb-operator.percona-everest" --ignore-not-found=true --no-headers | awk '{print $1}' &&  kubectl get crd -l="operators.coreos.com/percona-postgresql-operator.percona-everest" --ignore-not-found=true --no-headers | awk '{print $1}' && kubectl get crd -l="operators.coreos.com/percona-xtradb-cluster-operator.percona-everest" --ignore-not-found=true --no-headers | awk '{print $1}'

Remove ALL created CRD individually, or use:

 echo $(kubectl get crd -l="operators.coreos.com/percona-server-mongodb-operator.percona-everest" --ignore-not-found=true --no-headers | awk '{print $1}' &&  kubectl get crd -l="operators.coreos.com/percona-postgresql-operator.percona-everest" --ignore-not-found=true --no-headers | awk '{print $1}' && kubectl get crd -l="operators.coreos.com/percona-xtradb-cluster-operator.percona-everest" --ignore-not-found=true --no-headers | awk '{print $1}') | xargs  kubectl delete crd

Remove Everest OLM catalog:

kubectl delete -f https://raw.githubusercontent.com/percona/percona-everest-cli/v0.4.1/data/crds/olm/percona-dbaas-catalog.yaml

Remove OLM installation (Do not delete it if it was installed without Everest support):

kubectl delete -f https://raw.githubusercontent.com/percona/percona-everest-cli/v0.4.1/data/crds/olm/crds.yaml

kubectl delete -f https://raw.githubusercontent.com/percona/percona-everest-cli/v0.4.1/data/crds/olm/olm.yaml

Remove percona-everest namespace:
```
kubectl delete ns percona-everest
```
