Via Germain Wizard

Germain Workspace > Left Menu > Wizard > Docker

Enable Docker Engine API

1. Navigate to /lib/systemd/system in your terminal and open docker.service file

   CODE

   $ vi /lib/systemd/system/docker.service

2. Find the line which starts with ExecStart and adds -H=tcp://0.0.0.0:2375 to make it look like

   CODE

   ExecStart=/usr/bin/dockerd -H=fd:// -H=tcp://0.0.0.0:2375

3. Save the Modified File

4. Reload the docker daemon

   CODE

   $ sudo systemctl daemon-reload

5. Restart the docker service

   CODE

   $ sudo service docker restart

6. Test if it is working by using this command, if everything is fine below command should return a JSON

   CODE

   $ curl http://localhost:2375/images/json

7. To test remotely, use the PC name or IP address of Docker Host

Run Docker commands as a non-root user

To create the docker group and add your user:

1. Create the docker group.

   CODE

   $ sudo groupadd docker

2. Add your user to the docker group.

   CODE

   $ sudo usermod -aG docker $USER

3. Log out and log back in so that your group membership is re-evaluated.

   On Linux, you can also run the following command to activate the changes to groups:

   CODE

   $ newgrp docker 

4. Verify that you can run docker commands without sudo.

   CODE

   $ docker ps
