Docker Tricks

1. Accessing Container via IP Address

When using docker, the common usage is to use port forwarding via -p option. Accessing containers via it's IP address is only possible in linux. On Mac and Windows, docker container runs inside a some kind of virtual box.

To access container via IP on Mac, one can utilize sshuttle which require to run an ssh-server container.

docker run --rm --name sshdocker -p 2222:22 -d rastasheep/ubuntu-sshd:14.04
sshuttle -r [email protected]:2222 -N 172.17.0.0/24

Normally, container's IP is on 172.17.0.*. You can check it using docker container inspect [container_name] | grep IPAddress The default root password for rastasheep/ubuntu-sshd:14.04 is root.

Note: I haven't been able to run sshuttle against alpine-based ssh server. That's why ubuntu-based sshd is used.
