1、在 Rancher 的卷中，添加：/webtv:/data。如图1
2、查看容器的日志，报错：LOG_NAME: unbound variable。如图2
2020/8/3 下午4:40:16/config/init/cronlog.sh: line 5: LOG_NAME: unbound variable 2020/8/3 下午4:40:19sh: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) 2020/8/3 下午4:40:19bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) 2020/8/3 下午4:40:19/bin/sh: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
3、进入容器，查看 /data 下的目录列表，不符合预期。未挂载成功。如图3
[root@955ea658d009 data]# ls -l total 24 drwxr-xr-x 2 root root 4096 Apr 29 15:27 cmclogs drwx--x--x 2 root root 4096 Jun 28 11:31 conf drwxr-xr-x 2 root root 4096 Apr 21 16:13 log-static drwx--x--x 2 root root 4096 Jun 28 11:31 logs drwx--x--x 2 root root 4096 Jun 28 11:31 run drwxr-xr-x 6 root root 4096 Jun 28 12:42 wangjie
4、在 Rancher 的调度中，添加调度规则。如图4
5、再次升级后，进入容器，查看 /data 下的目录列表，符合预期。NAS 存储挂载成功。如图5

6、分析添加调度规则前后的区别。添加前，其主机为：lb。添加后，其主机为：wjdev02。如图6、图7
7、分别查看主机：lb、wjdev02 的存储，lb 上不存在 /webtv，wjdev02 上存在 /webtv。如图8、图9
