docker给已经启动容器添加挂载目录

docker添加挂载目录:先在docker容器里创建目录/import

1.关闭docker:/etc/init.d/docker stop
2.sudo su切换到root身份，cd /var/lib/docker/containers/容器id/，进入对应容器目录
3.vi hostconfig.json，修改如下，将容器目录/import绑定到主机/data目录:

"Binds": ["/data:/import"],

4.vi config.v2.json,修改如下，添加MountPoints:

"MountPoints": {

"/import": {
"Source": "/data",
"Destination": "/import",
"RW": true,
"Name": "",
"Driver": "",
"Type": "bind",
"Propagation": "rprivate",
"Spec": {
"Type": "bind",
"Source": "/data",
"Target": "/import"
},
"SkipMountpointCreation": false
}

},

5.启动docker:/etc/init.d/docker start

最后docker ecec -it 容器id /bin/bash进入ls -l /就可以看见import目录
