SSH remote Docker host

January 10, 2019

Let’s attempt to use SSH port forwarding to tunnel a remote Docker host to out local machine, granting us access to resources as if they are running locally.

First tunnel remote socket to a port on local machine.

ssh -nNT -L localhost:2345:/var/run/docker.sock [email protected]

Flag n prevents reading from stdin, N does not execute any command and T will not allocate a PTY.

Next open a new terminal and export DOCKER_HOST.

export DOCKER_HOST="localhost:2345"

While using this terminal, local docker commands are executed on remote server.
