（6）SUSE CaaS Platform 4 - 使用 Ceph RBD 作为持久存储（动态）
目前 CaaSP4 支持多种 Volume 类型，这里选择 Ceph RBD（Rados Block Device)，主要有如下好处：
1、搭建环境
2、虚拟化环境搭建和系统安装参考：
3、实验目的
配置 Pod 资源使用 RBD 存储卷
图1 环境架构
1、所有节点安装
# zypper -n in ceph-common
复制 ceph.conf 到 worker 节点上
# scp admin:/etc/ceph/ceph.conf /etc/ceph/
2、创建池 caasp4
# ceph osd pool create caasp4 128
3、创建 key ，并存储到 /etc/ceph/ 目录中
# ceph auth get-or-create client.caasp4 mon ‘allow r‘ osd ‘allow rwx pool=caasp4‘ -o /etc/ceph/caasp4.keyring
4、创建 RBD 镜像，2G
# rbd create caasp4/ceph-image-test -s 2048
5、查看 ceph 集群 key 信息，并生成基于 base64 编码的key
# ceph auth list
.......
client.admin
key: AQA9w4VdAAAAABAAHZr5bVwkALYo6aLVryt7YA==
caps: [mds] allow *
caps: [mgr] allow *
caps: [mon] allow *
caps: [osd] allow *
.......
client.caasp4
key: AQD1VJddM6QIJBAAlDbIWRT/eiGhG+aD8SB+5A==
caps: [mon] allow r
caps: [osd] allow rwx pool=caasp4
对 key 进行 base64 编码
# echo AQD1VJddM6QIJBAAlDbIWRT/eiGhG+aD8SB+5A== | base64
QVFEMVZKZGRNNlFJSkJBQWxEYklXUlQvZWlHaEcrYUQ4U0IrNUE9PQo=
6、Master 节点上，创建 secret 资源，插入 base64 key
# vi ceph-secret-test.yaml
apiVersion: v1
kind: Secret
metadata:
name: ceph-secret-test
data:
key: QVFEMVZKZGRNNlFJSkJBQWxEYklXUlQvZWlHaEcrYUQ4U0IrNUE9PQo=
# kubectl create -f ceph-secret-test.yaml
secret/ceph-secret-test created
# kubectl get secrets ceph-secret-test
NAME TYPE DATA AGE
ceph-secret-test Opaque 1 14s
7、创建 Pod，并使用存储卷
# mkdir /root/ceph_rbd_pod
# vim /root/ceph_rbd_pod/ceph-rbd-pod.yaml
apiVersion: v1
kind: Pod
metadata:
name: vol-rbd-pod
spec:
containers:
- name: ceph-busybox
image: busybox
command: ["sleep", "60000"]
volumeMounts:
- name: ceph-vol-test
mountPath: /usr/share/busybox
readOnly: false
volumes:
- name: ceph-vol-test
rbd:
monitors:
- 192.168.2.40:6789
- 192.168.2.41:6789
- 192.168.2.42:6789
pool: caasp4
image: ceph-image-test
user: caasp4
secretRef:
name: ceph-secret-test
fsType: ext4
readOnly: false
8、查看 Pod 状态和挂载
# kubectl get pods
NAME READY STATUS RESTARTS AGE
vol-rbd-pod 1/1 Running 0 22s
# kubectl get pods -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
vol-rbd-pod 1/1 Running 0 27s 10.244.2.59 worker02 <none> <none>
# kubectl describe pods vol-rbd-pod
Containers:
ceph-busybox:
.....
Mounts: # 挂载
/usr/share/busybox from ceph-vol-test (rw)
/var/run/secrets/kubernetes.io/serviceaccount from default-token-4hslq (ro)
.....
Volumes:
ceph-vol-test:
Type: RBD (a Rados Block Device mount on the host that shares a pod‘s lifetime)
CephMonitors: [192.168.2.40:6789 192.168.2.41:6789 192.168.2.42:6789]
RBDImage: ceph-image-test # RBD 镜像名
FSType: ext4 # 文件格式
RBDPool: caasp4 # 池
RadosUser: caasp4 # 用户
Keyring: /etc/ceph/keyring
SecretRef: &LocalObjectReference{Name:ceph-secret-test,}
ReadOnly: false
default-token-4hslq:
Type: Secret (a volume populated by a Secret)
SecretName: default-token-4hslq
Optional: false
.....
9、worker02节点上查看映射
worker02:~ # rbd showmapped
id pool namespace image snap device
0 caasp4 ceph-image-test - /dev/rbd0
SUSE CaaS Platform 4 - Ceph RBD 作为 Pod 存储卷
