1. 我们要重启这个镜像，需要知道这个镜像ID，类似这个：
7079ff99e10ac326726a364348853c0e508cad8ce00ae970f3c800f172a40252
那么你可以跳过下面的这个步骤:
1. 我们先找到docker 的存放位置，默认的docker 镜像防止在/var/lib/docekr 位置,但是一般来说var的目录比较小，如果我们存的image镜像比较大的话，可能需要修改默认存储地址，这个在这里不讲. 我们采用 sudo docker info 来查询
sudo docker info

我们没有发现
Docker Root Dir:
这个字段，所以说明目录存储在/var/lib/docker 目录下，所以我们直接在这个目录下去寻找就可以了.
我们这里是因为修改了docker的默认的存储路径:
[root@localhost ~]# sudo docker info

所以这里去/data1/docker下面寻找：
[root@localhost ~]# ls /data1/docker/containers
7079ff99e10ac326726a364348853c0e508cad8ce00ae970f3c800f172a40252
[root@localhost ~]#
然后我们使用这个重启：
首先，查看我们的容器信息：
sudo docker inspect 7079ff99e10ac326726a364348853c0e508cad8ce00ae970f3c800f172a40252
启动你的容器
sudo docker start 7079ff99e10ac326726a364348853c0e508cad8ce00ae970f3c800f172a40252
然后使用sudo docker ps 查看容器状态：
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7079ff99e10a xxxxxxx.xxx.xxx "/usr/sbin/entrypo..." weeks ago Up minutes elated_ramanujan
这样我们的容器就恢复了. 然后我们进入容器，去重启应用服务吧.
[root@localhost ~]# sudo docker exec -it 7079ff99e10a bash
然后就去恢复应用吧.
