-====== Docker - Enable Docker Remote API ======
-Docker provides a nice remote REST API.
-Edit or create a systemd dropin file under: **/etc/systemd/system/docker.service.d/remote-api.conf**
-With the contents:
-<file bash /etc/systemd/system/docker.service.d/remote-api.conf>
-[Service]
-ExecStart=
-ExecStart=/usr/bin/dockerd -H tcp://127.0.0.1:1234 -H unix:///var/run/docker.sock
-</file>
-<WRAP info>
-**NOTE:**  The double ExecStart is necessary!
-The following can be used instead of the 2nd ExecStart above.  **<nowiki>-H fd://</nowiki>** can also be used to refer to systemd's socket activation feature /lib/systemd/system/docker.socket.
-<code bash>
-ExecStart=/usr/bin/dockerd -H fd:// -H tcp://127.0.0.1:1234
-</code>
-It is recommended binding on 127.0.0.1 instead of 0.0.0.0, unless you have a good reason!
-</WRAP>
-This will have Docker bind to port 1234 which will be used by the Docker Remote API.
-One you have saved your changes, you will need to restart the Docker process by running the following command:
-<code bash>
-sudo systemctl daemon-reload
-sudo systemctl restart docker
-</code>
-Check that the dockerd process listening on port 1234:
-<code bash>
-sudo ss -tulpn | grep 1234
-tcp6       0      0 :::1234                 :::*                    LISTEN      1836/dockerd
-</code>
-To test that the Docker Remote API has been properly enabled, we will list the Images currently in Docker:
-<code bash>
-sudo docker images
-</code>
-Test by performing a GET operation on the following URL: http://172.30.0.199:1234/images/json as described in the [[https://docs.docker.com/engine/api/|Docker Remote API]].
-You can also easily test this by using CURL on the command-line by running the following command:
-<code bash>
-curl -X GET http://172.30.0.199:1234/images/json
-</code>
