Uninstall KubeDB

To uninstall KubeDB operator, run the following command:

$ curl -fsSL https://github.com/kubedb/installer/raw/v0.13.0-rc.0/deploy/kubedb.sh \
    | bash -s -- --uninstall [--namespace=NAMESPACE]

+ kubectl delete deployment -l app=kubedb -n kube-system
deployment "kubedb-operator" deleted
+ kubectl delete service -l app=kubedb -n kube-system
service "kubedb-operator" deleted
+ kubectl delete serviceaccount -l app=kubedb -n kube-system
No resources found
+ kubectl delete clusterrolebindings -l app=kubedb -n kube-system
No resources found
+ kubectl delete clusterrole -l app=kubedb -n kube-system
No resources found

The above command will leave the KubeDB crd objects as-is. If you wish to nuke all KubeDB crd objects, also pass the --purge flag. This will keep a copy of KubeDB crd objects in your current directory.

• Now, wait several seconds for KubeDB to stop running. To confirm that KubeDB operator pod(s) have stopped running, run:

  $ kubectl get pods --all-namespaces -l app=kubedb
  

• To keep a copy of your existing KubeDB objects, run:

  kubectl get postgres.kubedb.com --all-namespaces -o yaml > postgres.yaml
  kubectl get elasticsearch.kubedb.com --all-namespaces -o yaml > elasticsearch.yaml
  kubectl get memcached.kubedb.com --all-namespaces -o yaml > memcached.yaml
  kubectl get mongodb.kubedb.com --all-namespaces -o yaml > mongodb.yaml
  kubectl get mysql.kubedb.com --all-namespaces -o yaml > mysql.yaml
  kubectl get redis.kubedb.com --all-namespaces -o yaml > redis.yaml
  kubectl get snapshot.kubedb.com --all-namespaces -o yaml > snapshot.yaml
  kubectl get dormant-database.kubedb.com --all-namespaces -o yaml > data.yaml
  

• To delete existing KubeDB objects from all namespaces, run the following command in each namespace one by one.

  kubectl delete postgres.kubedb.com --all --cascade=false
  kubectl delete elasticsearch.kubedb.com --all --cascade=false
  kubectl delete memcached.kubedb.com --all --cascade=false
  kubectl delete mongodb.kubedb.com --all --cascade=false
  kubectl delete mysql.kubedb.com --all --cascade=false
  kubectl delete redis.kubedb.com --all --cascade=false
  kubectl delete snapshot.kubedb.com --all --cascade=false
  kubectl delete dormant-database.kubedb.com --all --cascade=false
  

• Delete the old CRD-registration.

  kubectl delete crd -l app=kubedb
