How do I change the Docker image installation directory?

Open Source Projects DockerEngine
18

Ob Ubuntu 16.04 Server (64bit) I could successfully change the path by editing the

/etc/systemd/system/docker.service.d

like this

[Service]
EnvironmentFile=-/etc/sysconfig/docker
EnvironmentFile=-/etc/sysconfig/docker-storage
EnvironmentFile=-/etc/sysconfig/docker-network
ExecStart=
ExecStart=/usr/bin/docker daemon -H 0.0.0.0:2376 -H unix:///var/run/docker.sock $OPTIONS \
          $DOCKER_STORAGE_OPTIONS \
          $DOCKER_NETWORK_OPTIONS \
          $BLOCK_REGISTRY \
          --tlsverify \
          --tlscacert=/etc/docker/cert/ca.pem \
          --tlscert=/etc/docker/cert/server-cert.pem \
          --tlskey=/etc/docker/cert/server-key.pem \
          -g /data/docker

Added the line with -g (and don’t forget the ’ ’ in the line before).
