Help with connecting to docker socket proxy

[Sak]

Hi, I am trying to improve security on my unraid server as I have many exposed containers.
One of the way is to user docker socket proxy for any containers that requires access to docker socket.

 

some containers such as dozzle lets me set the socket endpoint through an environment variable.

but my sablier container does not have that option.

 

I found an example online where you can use the --host or -H command to set the daemon host.

In the compose.yml file you can set it easily through the "command" block

 command: -H tcp://socket-proxy:2375

 

How can I do the same with the unraid docker gui? I have tried adding it as an extra parameter but that did not work.

I've gotta similar question, so I'm invested in this one.
