Manager for Longhorn.
- Existing Kubernetes Cluster 1.8+
- Make sure
open-iscsihas been installed on the host.
- Make sure
curlhas been installed on the host, for the Longhorn Flexvolume Driver.
kubectl create -Rf deploy/install
It will deploy the following components in the
- Longhorn Manager
- Longhorn Flexvolume Driver for Kubernetes
- Longhorn UI
Longhorn CRD has finalizers in them, so user should delete the volumes and related resource first, give manager a chance to clean up after them.
To prevent damage to the Kubernetes cluster, we recommend deleting all Kubernetes workloads using Longhorn volumes (PersistentVolume, PersistentVolumeClaim, StorageClass, Deployment, StatefulSet, DaemonSet, etc).
- Create the uninstallation job to cleanly purge CRDs from the system and wait for success:
kubectl create -f deploy/uninstall/uninstall.yaml kubectl get job/longhorn-uninstall -w
$ kubectl create -f https://raw.githubusercontent.com/rancher/longhorn/master/uninstall/uninstall.yaml serviceaccount/longhorn-uninstall-service-account created clusterrole.rbac.authorization.k8s.io/longhorn-uninstall-role created clusterrolebinding.rbac.authorization.k8s.io/longhorn-uninstall-bind created job.batch/longhorn-uninstall created $ kubectl get job/longhorn-uninstall -w NAME COMPLETIONS DURATION AGE longhorn-uninstall 0/1 3s 3s longhorn-uninstall 1/1 20s 20s ^C
- Remove remaining components:
kubectl delete -Rf deploy/install kubectl delete -f deploy/uninstall/uninstall.yaml
Tip: If you try
kubectl delete -Rf deploy/install first and get stuck there,
Ctrl C then running
kubectl create -f deploy/uninstall/uninstall.yaml can also help you remove Longhorn. Finally, don't forget to cleanup remaining components by running
kubectl delete -f deploy/uninstall/uninstall.yaml.
Google Kubernetes Engine
You will need to create cluster-admin role binding for yourselves before creating the deployment, see here for details.
kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=<email@example.com>
Flexvolume Plugin Directory
By default we're using the default Flexvolume Plugin directory, which is
For GKE 1.8+, it should be at:
You may need to change
flexvolume-longhorn-mount location according to your own environment.
