Destroy TiDB Clusters in Kubernetes
This document describes how to destroy TiDB clusters in Kubernetes.
Destroy a TiDB cluster managed by TidbCluster
To destroy a TiDB cluster managed by TidbCluster
, run the following command:
kubectl delete tc ${cluster_name} -n ${namespace}
If you deploy the monitor in the cluster using TidbMonitor
, run the following command to delete the monitor component:
kubectl delete tidbmonitor ${tidb_monitor_name} -n ${namespace}
Destroy a TiDB cluster managed by Helm
To destroy a TiDB cluster managed by Helm, run the following command:
helm uninstall ${cluster_name} -n ${namespace}
Delete data
The above commands that destroy the cluster only remove the running Pod, but the data is still retained. If you want to delete the data as well, use the following commands:
Warning
The following commands delete your data completely. Please be cautious.
To ensure data safety, do not delete PVs on any circumstances, unless you are familiar with the working principles of PVs.
kubectl delete pvc -n ${namespace} -l app.kubernetes.io/instance=${cluster_name},app.kubernetes.io/managed-by=tidb-operator
kubectl get pv -l app.kubernetes.io/namespace=${namespace},app.kubernetes.io/managed-by=tidb-operator,app.kubernetes.io/instance=${cluster_name} -o name | xargs -I {} kubectl patch {} -p '{"spec":{"persistentVolumeReclaimPolicy":"Delete"}}'
