This plugin is compatible with Docker 1.7.1 or later.
- To install new meter go to Settings->Installation or see instructions.
- To upgrade the meter to the latest version - see instructions.
Docker must run in deamon mode binded to a host and port. Follow the instructions below:
Edit /etc/default/docker and add DOCKER_OPTS="-H 127.0.0.1:2375" & restart the service
$ sudo service docker restart
Edit /etc/sysconfig/docker and add OPTIONS="-H 127.0.0.1:2375" & restart the service
$ sudo service docker restart
- Log into your host as a user with sudo or root privileges.
- Create the /etc/systemd/system/docker.service.d directory.
$ sudo mkdir /etc/systemd/system/docker.service.d
- Create a /etc/systemd/system/docker.service.d/docker.conf file.
- Open the file with your favorite editor.
$ sudo vi /etc/systemd/system/docker.service.d/docker.conf
- Override the ExecStart configuration from your docker.service file to customize the docker daemon. To modify the ExecStart configuration you have to specify an empty configuration followed by a new one as follows:
[Service]
ExecStart=
ExecStart=/usr/bin/docker daemon -H tcp://127.0.0.1:2375 -H unix:///var/run/docker.sock
- Save the changes
- Flush changes.
$ sudo systemctl daemon-reload
- Restart the docker daemon.
$ sudo systemctl restart docker
