I have been trying to connect to a docker container via ip, but reamins unsuccessful. When I used "docker inspect container-id" I get this result.

Can someone help me resolving this issue?

When running docker, you can specify which port(s) you'd like to be accessible to the outside world. Basic syntax is:
docker run -p hostPort:containerPort imageName or just
docker run -p hostPort imageName In the first case, externally, hostPort will be used, but inside the container: containerPort will be used. In the second instance, you'd just be using that port both inside and outside your container.
You can also create an image with ports exposed by using the EXPOSE command in a Dockerfile.

I commit the container, stopped it, and then run the latest image by using docker run -p 2375 imageName, but still no result...

Does
docker inspect new_container_id show the same thing?

Here you are specifying the image name, what if we have a container with modification and data in the database, and we want to expose a certain port on that container.
You need to perform port forwarding or just simply expose port.
Port Forwarding:
docker run -p 2022:22 -p 2375:2375
Expose Port:
docker run -p 22 -p 2375
-p <port number>parameter to make that port available (or useexposein the Dockerfile)?
