ubuntu18.04 snap装的docker 修改daemo

比如说想添加insucure-registy,

修改daemson.json:
/var/snap/docker/current/config/daemon.json

{
    "insecure-registries" : [ "hostname.cloudapp.net:5000" ]
}

然后重启 sudo snap restart docker

ps -ef | grep dockerd
查看snap docker实际加载的是 /var/snap/docker/384/config/daemon.json 而不是current目录

我更改current目录之后384也自动修改了
