ceph集群存储部署

参考文档：https://rook.github.io/docs/rook/v1.12/Getting-Started/quickstart/#prerequisites

1、下载部署文件

git clone --single-branch --branch v1.12.4 https://github.com/rook/rook.git

2、部署 Rook Operator

cd rook/deploy/examples
kubectl create -f crds.yaml -f common.yaml -f operator.yaml

3、创建 Ceph 集群

kubectl create -f cluster.yaml

4、安装Rook 工具箱

kubectl create -f toolbox.yaml

5、安装ceph控制台，控制台的访问不详说，可以参考上面的参考文档

kubectl create -f dashboard-external-https.yaml

6、查看rook-ceph是否正常运行

[root@h03 ~]# kubectl -n rook-ceph get pod

7、创建cephfs

kubectl create -f filesystem.yaml

8、配置存储

kubectl create -f csi/cephfs/storageclass.yaml

9、创建pvc示例

# 创建pvc的yaml文件
cat <<EOF > common-data-pvc.yml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: common-data-pvc
  namespace: huwang
spec:
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 1024Gi
  storageClassName: rook-cephfs
EOF

# 部署pvc
kubectl create -f common-data-pvc.yml
