Using WALs to provide durability is a common technique for applications that use consensus protocols to achieve a replicated state machine.\n\nUse the kubectl delete command to delete the zk StatefulSet.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl delete statefulset zk\n```\n\nBounded code example (external data; do not execute automatically):\n```text\nstatefulset.apps \"zk\" deleted\n```\n\nWatch the termination of the Pods in the StatefulSet.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get pods -w -l app=zk\n```\n\nWhen zk-0 if fully terminated, use CTRL-C to terminate kubectl.\n\nBounded code example (external data; do not execute automatically):\n```text\nzk-2      1/1       Terminating   0         9m\nzk-0      1/1       Terminating   0         11m\nzk-1      1/1       Terminating   0         10m\nzk-2      0/1       Terminating   0         9m\nzk-2      0/1       Terminating   0         9m\nzk-2      0/1       Terminating   0         9m\nzk-1      0/1       Terminating   0         10m\nzk-1      0/1       Terminating   0         10m\nzk-1      0/1       Terminating   0         10m\nzk-0      0/1       Terminating   0         11m\nzk-0      0/1       Terminating   0         11m\nzk-0      0/1       Terminating   0         11m\n```\n\nReapply the manifest in zookeeper.yaml.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl apply -f https://k8s.io/examples/application/zookeeper/zookeeper.yaml\n```\n\nThis creates the zk StatefulSet object, but the other API objects in the manifest are not modified because they already exist.\n\nWatch the StatefulSet controller recreate the StatefulSet's Pods.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get pods -w -l app=zk\n```\n\nOnce the zk-2 Pod is Running and Ready, use CTRL-C to terminate kubectl. …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
