docker卷管理

这里使用

docker卷管理

server1 2

yum install nfs-utils -y

保证打开服务rpcbind

mkdir /mnt/nfs

server1

vim /etc/exports

/mnt/nfs *(rw,no_root_squash) 或者改为777权限 chmod 777 /mnt/nfs

exportfs -rv

systemctl start nfs

showmount -e 172.25.11.1

server2

mkdir /mnt/nfs

mount 172.25.11.1:/mnt/nfs /mnt/nfs

server 1 2都做

需要插件 convoy.tar.gz

tar zxf convoy.tar.gz

cp convoy/convoy* /usr/local/bin/

cd /etc/docker

mkdir plugins

convoy daemon --drivers vfs --driver-opts vfs.path=/mnt/nfs &> /dev/null &

这样没有日志输出

cat /var/run/convoy/convoy.sock

/etc/docker/plugins/convoy.spec

spec是用来构建rpm包的文件

\vi convoy.spec 即可

echo "unix:///var/run/convoy/convoy.sock" > /etc/docker/plugins/convoy.spec

创建卷

server1

convoy create vol1

convoy list

[[email protected] docker]# convoy list
{
   "vol1": {
       "Name": "vol1",
       "Driver": "vfs",
       "MountPoint": "",
       "CreatedTime": "Sun Mar 17 14:04:25 +0800 2019",
       "DriverInfo": {
           "Driver": "vfs",
           "MountPoint": "",
           "Path": "/mnt/nfs/vol1",
           "PrepareForVM": "false",
           "Size": "0",
           "VolumeCreatedAt": "Sun Mar 17 14:04:25 +0800 2019",
           "VolumeName": "vol1"
       },
       "Snapshots": {}
   }
}

server2

convoy list 会自动扫描到vol1

/mnt/nfs/vol1 为目录

使用卷

server1

docker run -it --name vm1 -v vol1:/data ubuntu

[[email protected] docker]# touch /mnt/nfs/vol1/{1..3}

server2

ll /mnt/nfs/vol1

docker run -it --name vm1 -v vol1:/data ubuntu

[email protected]:/data# ls
1 2 3

都是可以读写的共享

删除卷

docker rm vm1

convoy delete vol1
