kubernetes連接ceph rbd存儲

1. 爲kubernetes創建一個存儲池
   ceph osd pool create k8s 128

2.爲ceph添加一個kubernetes secret
[root@k8s-master1 ceph]# echo "$(ceph auth get-key client.admin)"|base64
QVFCTk9DZGNlWXM4TEJBQTJ4YTROcGh5WUhaN2FBWGNRV1VFVHc9PQo=

[root@k8s-master1 ceph]# cat ceph-secret.yaml
apiVersion: v1
kind: Secret
metadata:
name: ceph-secret
namespace: kube-system
type: "kubernetes.io/rbd"
data:
key: "QVFCTk9DZGNlWXM4TEJBQTJ4YTROcGh5WUhaN2FBWGNRV1VFVHc9PQo="

[root@k8s-master1 ceph]kubectl create -f ceph-secret.yaml

3. 創建一個StorageClass
   ceph-rbd-storageclass.yaml

[root@k8s-master1 ceph]# cat ceph-secret.yaml
apiVersion: v1
kind: Secret
metadata:
name: ceph-secret
namespace: kube-system
type: "kubernetes.io/rbd"
data:
key: "QVFCTk9DZGNlWXM4TEJBQTJ4YTROcGh5WUhaN2FBWGNRV1VFVHc9PQo="
[root@k8s-master1 ceph]# cat ceph-
ceph-pvc.json ceph-rbd-storageclass.yaml ceph-secret.yaml
[root@k8s-master1 ceph]# cat ceph-rbd-storageclass.yaml
apiVersion: storage.k8s.io/v1beta1
kind: StorageClass
metadata:
name: fast
provisioner: kubernetes.io/rbd
parameters:
monitors: 192.168.1.86:6789,192.168.1.87:6789,192.168.1.88:6789
adminId: admin
adminSecretName: ceph-secret
adminSecretNamespace: kube-system
pool: k8s
userId: admin
userSecretName: ceph-secret

[root@k8s-master1 ceph]kubectl create -f ceph-rbd-storageclass.yaml
[root@k8s-master1 ceph]kubectl get storageclass

4.測試
ceph-pvc.json
{
"kind": "PersistentVolumeClaim",
"apiVersion": "v1",
"metadata": {
"name": "claim1",
"annotations": {
"volume.beta.kubernetes.io/storage-class": "fast"
}
},
"spec": {
"accessModes": [
"ReadWriteOnce"
],
"resources": {
"requests": {
"storage": "3Gi"
}
}
}
}
