RBD mounting steps for Kubernetes ceph

K8s Cluster Install the client on each of the above:

Ceph-deploy Install k8s IP address

Create a k8s action user :

Ceph auth Add client.k8s mon ' Allow rwx ' OSD ' Allow rwx '

Ceph auth get client.k8s-o/etc/ceph/ceph.client.k8s.keyring #导出新建用户的钥匙 to place the exported keys under the/etc/ceph/of each k8s

Ceph Auth List #查看权限

Creating a pool and mapping

1. Create a pool named K8spool

Ceph OSD Pool Create K8spool 2024

Ceph OSD Pool ls #查看池

2. Create a block map k8stest

RBD Create--size 1024x768 k8spool/k8stest

RBD ls--pool k8spool #查看建立的映射

3. Turn off options not supported by the CENTOS7 kernel

RBD feature Disable K8spool/k8stest exclusive-lock, Object-map, Fast-diff, Deep-flatten

K8s Operation:

1. Create the key:

grep key /etc/ceph/ceph.client.admin.keyring |awk ‘{printf "%s", $NF}‘|base64QVFBbW5SbFgyenJxRFJBQU9pdU9zMnNJSXRHaEFQNnRORGEzVmc9PQ==

2. Create K8S-PV

3. Create K8S-PVC

4. Create a test pod to see if you can mount Ceph

Successful view:

Kubectl describe Pod/ceph-rbd-pv-pod1 #查看是否成功
