All steps are relevant for distributions with systemd<\/strong> (tested on CentOS 7<\/strong> and Ubuntu 18.04<\/strong>)<\/p>\n

We look at the Docker<\/strong> launch command:<\/p>\n

\r\ngrep "ExecStart" \/usr\/lib\/systemd\/system\/docker.service\r\n<\/pre>\n
Ubuntu 18.04<\/strong> has a different path, "\/lib\/systemd\/system\/docker.service<\/strong>"<\/p><\/blockquote>\n
 <\/p>\n
We get something similar:<\/p>\n
\r\nExecStart=\/usr\/bin\/dockerd\r\n<\/pre>\n
Now create the "override.conf<\/strong>" file, just enter:<\/p>\n
\r\nsystemctl edit docker\r\n<\/pre>\n
We insert the following there:<\/p>\n
\r\n[Service]\r\nExecStart=\r\nExecStart=\/usr\/bin\/dockerd -H tcp:\/\/0.0.0.0:2375\r\n<\/pre>\n
<\/p>\n
For Ubuntu 18.04<\/strong>:<\/p>\n
\r\n[Service]\r\nExecStart=\r\nExecStart=\/usr\/bin\/dockerd -H tcp:\/\/0.0.0.0:2375 -H unix:\/\/\/var\/run\/docker.sock\r\n<\/pre>\n
ExecStart<\/strong> should be two, the first with an empty value. In the previous step, we looked at the launch command, and added parameters for TCP<\/strong> to it.<\/p>\n
Reload the configuration of the daemon:<\/p>\n
\r\nsystemctl daemon-reload\r\n<\/pre>\n
Restart Docker<\/strong> and see its status:<\/p>\n
\r\nsystemctl restart docker\r\n<\/pre>\n
\r\nsystemctl status docker\r\n<\/pre>\n
If all is well, then you can still verify that Docker<\/strong> is listening on the port:<\/p>\n
\r\nnetstat -anp | grep ":2375"\r\n<\/pre>\n
Now you can remotely execute Docker<\/strong> commands, but you should consider that there is no authentication in this scheme.<\/p>\n","protected":false},"excerpt":{"rendered":"
