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.
My virtual box settings are by default:
Can someone help me resolving this issue?
回答1:
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.

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
