I'm sure this question has been answered before, but I cannot find a simple solution anywhere. I have multiple docker-compose projects running on a single host, with unique host port mappings.
I'd like to access a Flask API from outside the server, but cannot work out how to do this. There seems to be an option when running docker-compose run -p, but I was of the understanding that docker-compose up -d is the preferred and robust way to run compose.
I tried changing network_mode: "bridge" to network_mode: "host", but this didn't help.
Let's say the IP of the host is 123.23.23.111, I would like to access the api service externally via something like http://123.23.23.111:5004, as well as the Flower monitor via http://123.23.23.111:5559.
It's all running on a private network, and I would like another server on the private network to access the API, but no internet access is needed. https will be added later.
