Uninstall Everest¶

No matter why you need to uninstall Everest, you can run the commands below to remove all the Everest resources including:

All Kubernetes objects created by Everest
All Docker containers created by Everest
All downloaded binaries and files like everestctl, quickstart.yml.

Warning

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

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:

Warning

Follow these cleanup instructions after unprovisioning Everest via CLI.

Remove ALL created database clusters:

kubectl delete db --all -n percona-everest

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:

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/v0.3.0/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/v0.3.0/data/crds/olm/crds.yaml

kubectl delete -f https://raw.githubusercontent.com/percona/percona-everest-cli/v0.3.0/data/crds/olm/olm.yaml

```
docker compose -f quickstart.yml down
