Unable to connect to Docker container from browser on host

Asked 2 years ago, Updated 2 years ago, 124 views

How do I connect to a Docker container port from a browser on my host?
The Dockerfile, docker-compose.yml below allows the host to connect to port 1344, but even if you access localhost:1344 in the host browser, you will not be able to establish a connection to the server

On port 1344, I run the bottle (waf of python) application

Docker version:Docker 1.12.0-rc4-beta19

This is probably because there is no description of CMD (or ENTRYPOINT) in the Dockerfile.

I'm not familiar with Python, so I can't give you a specific example, but I think I should write a command to run the bottle.

Also, if you try docker run and check the process with the ps command, it may not work.
