+## 2023-10-8前使用该脚本在K8S部署consul的同学请注意.
+1. 完成第3步操作前不要删除consul的pod,也不要重启consul
+2. 使用kubectl进入conusl的容器`kubectl exec -i -t -n tensuns consul-0 -c consul -- sh -c "sh"`
+3. 备份consul的KV存储数据
+```
+consul kv export --http-addr=http://127.0.0.1:8500 -token=$(cat /consul/config/consul.hcl|grep agent|awk -F\" '{print $2}') '' > /consul/data/consul_kv_bak.json
+```
+4. 修改consul的Stateful Sets的yaml文件, 找到`image`字段下面, 增加`args`部分:
+```
+          args:
+            - agent
+```
+  - 增加完成后应该是如下效果:
+```
+...
+      containers:
+        - name: consul
+          image: swr.cn-south-1.myhuaweicloud.com/starsl.cn/consul:latest
+          args:
+            - agent
+          ports:
+            - name: http
+              containerPort: 8500
+              protocol: TCP
+...
+```
+5. 保存后重启consul的Stateful Sets
+6. 启动完成后再次使用第2步进入consul容器
+7. 恢复consul的KV存储数据
+```
+consul kv import --http-addr=http://127.0.0.1:8500 -token=$(cat /consul/config/consul.hcl|grep agent|awk -F\" '{print $2}') @/consul/data/consul_kv_bak.json
+```
+8. 完成,可再次重启consul后,验证consul kv数据是否丢失(能正常登录TenSunS说明KV数据正常).
