由于kubelet本身并不支持rbd的命令,所以需要添加一个kube系统插件:
下载插件 quay.io/external_storage/rbd-provisioner
下载地址:
https://quay.io/repository/external_storage/rbd-provisioner?tag=latest&tab=tags
在k8s集群的node上面下载 docker pull quay.io/external_storage/rbd-provisioner:latest
只安装插件本身会报错:需要安装kube的角色和权限 以下是下载地址:
https://github.com/kubernetes-incubator/external-storage
https://github.com/kubernetes-incubator/external-storage/tree/master/ceph/rbd/deploy/rbac #下载kube的role的yaml文件
下载rbac文件夹:
使用: kubectl apply -f rbac/
运行rbd-provisioner
如果报错:
报错因为rbd-provisioner的镜像中不能找到ceph的key和conf,需要把集群中key和conf拷贝进rbd-provisioner的镜像。
找到rbd-provisioner的镜像运行节点
docker cp /etc/ceph/ceph.client.admin.keyring <镜像名>:/etc/ceph/
docker cp /etc/ceph/ceph.conf <镜像名>:/etc/ceph/
如果又报错:
一直处于Pending,因为linux内核不支持 image format 1,所以我们要在sc中加入新建镜像时给他规定镜像的格式为2
在stroageclass中添加:
imageFormat: "2"
imageFeatures: "layering"
这样pvc就创建成功:
安装插件及角色(rbac):
#clusterrole.yaml kind: ClusterRole apiVersion: rbac.authorization.k8s.io/v1 metadata: name: rbd-provisioner rules: - apiGroups: [""] resources: ["persistentvolumes"] verbs: ["get", "list", "watch", "create", "delete"] - apiGroups: [""] resources: ["persistentvolumeclaims"] verbs: ["get", "list", "watch", "update"] - apiGroups: ["storage.k8s.io"] resources: ["storageclasses"] verbs: ["get", "list", "watch"] - apiGroups: [""] resources: ["events"] verbs: ["list", "watch", "create", "update", "patch"] - apiGroups: [""] resources: ["services"] resourceNames: ["kube-dns"] verbs: ["list", "get"] #clusterrolebinding.yaml kind: ClusterRoleBinding apiVersion: rbac.authorization.k8s.io/v1 metadata: name: rbd-provisioner subjects: - kind: ServiceAccount name: rbd-provisioner namespace: default roleRef: kind: ClusterRole name: rbd-provisioner apiGroup: rbac.authorization.k8s.io #deployment.yaml apiVersion: extensions/v1beta1 kind: Deployment metadata: name: rbd-provisioner spec: replicas: 1 strategy: type: Recreate template: metadata: labels: app: rbd-provisioner spec: containers: - name: rbd-provisioner image: "quay.io/external_storage/rbd-provisioner:latest" env: - name: PROVISIONER_NAME value: ceph.com/rbd #定义插件的名字 serviceAccount: rbd-provisioner #role.yaml apiVersion: rbac.authorization.k8s.io/v1 kind: Role metadata: name: rbd-provisioner rules: - apiGroups: [""] resources: ["secrets"] verbs: ["get"] #rolebinding.yaml apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: rbd-provisioner roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: rbd-provisioner subjects: - kind: ServiceAccount name: rbd-provisioner namespace: default #serviceaccount.yaml apiVersion: v1 kind: ServiceAccount metadata: name: rbd-provisioner
创建storageClass:
kind: StorageClass apiVersion: storage.k8s.io/v1 metadata: name: rbd provisioner: ceph.com/rbd #使用插件来生成sc parameters: monitors: 10.101.3.9:6789,10.101.3.11:6789,10.101.3.12:6789 adminId: admin adminSecretName: ceph-k-secret adminSecretNamespace: default #这里使用default 如果使用其他就要修改还要修改插件中的 pool: rbd userId: admin userSecretName: ceph-k-secret fsType: ext4 imageFormat: "2" imageFeatures: "layering"
创建PVC:
apiVersion: v1 kind: PersistentVolumeClaim metadata: name: ceph-rbd-dyn-pv-claim spec: accessModes: - ReadWriteOnce storageClassName: rbd resources: requests: storage: 1Gi
kubernetes ceph-rbd挂载步骤 类型storageClass
