## ceph側執行
1. ceph創建kubernetes存儲池
```shell
$ ceph osd pool create kubernetes 128 128
pool 'kubernetes' created
```
2. 初始化存儲池
```shell
$ rbd pool init kubernetes
```
3. 為 Kubernetes 和 ceph-csi 創建一個新用戶
```shell
sudo ceph auth get-or-create client.kubernetes mon 'profile rbd' osd 'profile rbd pool=kubernetes' mgr 'profile rbd pool=kubernetes' -o /etc/ceph/ceph.client.kubernetes.keyring
```
4. 獲取ceph相關信息
```shell
$ ceph mon dump
epoch 2
fsid b87d2535-406b-442d-8de2-49d86f7dc599
last_changed 2022-06-15T17:35:37.096336+0800

## k8s部署ceph-csi
> 本文章ceph-csi部署在 `kube-storage` 命名空間下
1. 創建命名空間
```shell
$ sudo mkdir -p /etc/kubernetes/addons/cephrbd && \
sudo chown -R ${USER}./etc/kubernetes/addons/cephrbd && \
cd /etc/kubernetes/addons/cephrbd
$ cat << EOF | tee 0.namespace.yml >> /dev/null
apiVersion: v1
kind: Namespace
metadata:
name: csi-system
EOF
$ kubectl apply -f 0.namespace.yml
namespace/kube-storage created
```
2. 生成類似于以下示例的 csi-config-map.yaml 文件，將 fsid 替換為“clusterID”，并將監視器地址替換為“monitors”：
```shell
$ cat << EOF | tee 1.csi-config-map.yml >> /dev/null
apiVersion: v1
kind: ConfigMap
data:
config.json: |-
[
{
"clusterID": "b87d2535-406b-442d-8de2-49d86f7dc599",
"monitors": [
"192.168.31.69:6789",
"192.168.31.102:6789",
"192.168.31.165:6789"
]
}
]
metadata:
name: ceph-csi-config
namespace: csi-system
EOF
$ kubectl apply -f 1.csi-config-map.yml
configmap/ceph-csi-config created
```
> 根據ceph側執行的返回結果來填寫內容
3. 創建csi的kvs配置文件
```shell
$ cat << EOF | tee 2.csi-kms-config-map.yml >> /dev/null
apiVersion: v1
kind: ConfigMap
data:
config.json: |-
{}
metadata:
name: ceph-csi-encryption-kms-config
namespace: csi-system
EOF
$ kubectl apply -f 2.csi-kms-config-map.yml
configmap/ceph-csi-encryption-kms-config createdv
```
4. 創建rbd的訪問權限
```shell
$ cat << EOF | tee 3.csi-rbd-secret.yml >> /dev/null
apiVersion: v1
kind: Secret
metadata:
name: csi-rbd-secret
namespace: csi-system
stringData:
userID: kubernetes
# ceph auth get-key client.kubernetes 獲取key，不需要base64。
userKey: AQCfkKpidBhVHBAAJTzhkRKlSMuWDDibrlbPDA==
EOF
$ kubectl apply -f 3.csi-rbd-secret.yml
secret/csi-rbd-secret created
```
5. 創建ceph配置文件以及密鑰文件
```shell
$ kubectl -n csi-system create configmap ceph-config --from-file=/etc/ceph/ceph.conf --from-file=keyring=/etc/ceph/ceph.client.kubernetes.keyring
configmap/ceph-config created
```
6. 創建相關的rbac權限
```shell
$ cat << EOF | tee 4.csi-provisioner-rbac.yaml >> /dev/null

如果kubelet數據目錄有做修改的話，請修改相關的配置。
例如，kubelet數據目錄在`/data/k8s/data/kubelet`目錄下。那么請執行 `sed -ri 's#/var/lib/kubelet#/data/k8s/data/kubelet#g' 7.csi-rbdplugin.yml` 來修改配置文件
> sed -ri 's@registry.k8s.io/sig-storage@172.139.20.170:5000/csi@g' 7.csi-rbdplugin.yml
> sed -ri 's@quay.io/cephcsi@172.139.20.170:5000/csi@g' 7.csi-rbdplugin.yml
9. 創建SC動態供應
```shell
$ cat << EOF | tee 8.csi-rbd-sc.yaml >> /dev/null
---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: csi-rbd-sc
provisioner: rbd.csi.ceph.com
parameters:
clusterID: b87d2535-406b-442d-8de2-49d86f7dc599
pool: kubernetes

csi.storage.k8s.io/controller-expand-secret-name: csi-rbd-secret
csi.storage.k8s.io/controller-expand-secret-namespace: csi-system
csi.storage.k8s.io/node-stage-secret-name: csi-rbd-secret
csi.storage.k8s.io/node-stage-secret-namespace: csi-system
reclaimPolicy: Delete
allowVolumeExpansion: true
mountOptions:
- discard
EOF
$ kubectl apply -f 8.csi-rbd-sc.yaml
storageclass.storage.k8s.io/csi-rbd-sc created
```
> 注意修改 `clusterID` 字段內容

## 驗證
創建一個1Gb的pvc
```shell
$ cat << EOF | tee 9.raw-block-pvc.yaml >> /dev/null
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: raw-block-pvc
spec:
accessModes:
- ReadWriteOnce
volumeMode: Block
resources:
requests:
storage: 1Gi
storageClassName: csi-rbd-sc
EOF
$ kubectl apply -f 9.raw-block-pvc.yaml
persistentvolumeclaim/raw-block-pvc created
$ kubectl get pvc raw-block-pvc
