docker imageファイルの保存先

Posted at 2019-12-15

以下やろうと思ったけど symlinkだといろいろエラーになるのでやめた

do the trick:

/etc/docker/daemon.json

{
"graph": "/mnt",
"storage-driver": "overlay2"
}
Despite the method you have to reload configuration and restart Docker:

sudo systemctl daemon-reload
sudo systemctl restart docker
To confirm that Docker was reconfigured:

docker info|grep "loop file"
In recent version (17.03) different command is required:

docker info|grep "Docker Root Dir"
Docker Root Dir: /mnt/docker

sudo docker info
(snip)
Storage Driver: overlay2
