How to assign as static port to a container?
docker, port
Solution
Per the docker.io documentation: https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/
$ sudo docker run -p 80:80 <image> <cmd>
Default port redirects can be built into a container with the EXPOSE build command.
Problem
I want to assign a container a port, so that it gets the same port after every restart of the container. Example: I have a container, which has an Apache in it. The Apache runs on port 80 inside the container. Now, after starting the container, docker assigns a host port to the container port, for example: 49154 -> 80. But the host port changes after restart, depending on the number of running containers. I tried to specify the port in the config.json file of the container, but it gets overwritten. Is it possible to specify the host port manually? Thanks in advance and best regards, Chris
