Run Docker image on a different host - docker

Question

Is it possible to run docker image on other host than localhost?
Ports 80 and 443 are always occupied by other applications, so I was wondering if it's possible to run it on, e.g. 192.168.0.100, and then set up the /etc/hosts file to assign a name for that IP address.
I was trying to set up extra_hosts option, but I'm not sure if it's meant for that. Either way, I did not succeed with setting it up as there was some issue with Value should be a mapping, not an array.
I guess it's worth mentioning that I'm on macOS using docker-compose to run everything. Thank you in advance.

}

Why not use a different port when running your image? (unless you have to use port 80/443)
So, for example, if you are running a webserver image like Apache httpd, which normally runs on port 80 use:
docker run -p 127.0.0.1:8080:80/tcp httpd
Then you can just use port 8080 on localhost.
For docker-compose add a ports section to the docker-compose.yaml file. E.g.
image: <image>
ports:
- "8080:80"
The actual ports/image would depend on which image you are using.
See https://docs.docker.com/compose/compose-file/#ports for details.
