Docker Context

How to manage another docker instance e.g. deploy/manage docker compose files on a Raspberry Pi

Resources

Prerequisites

You should set up passwordless ssh access between your machines.

Adding a Remote Context

  1. Create the context: docker context create dietpi1 --docker "host=ssh://root@192.168.1.11"

  2. View the new context using: docker context ls 

    /c/Windows/System32 ❯ docker context ls
NAME              DESCRIPTION                               DOCKER ENDPOINT                             ERROR
default           Current DOCKER_HOST based configuration   npipe:////./pipe/docker_engine
desktop-linux *   Docker Desktop                            npipe:////./pipe/dockerDesktopLinuxEngine
dietpi1                                                     ssh://root@192.168.1.11

  3. If you need to update the context: docker context update --description "RaspberryPi 3b; DietPi" --docker "host=ssh://root@192.168.1.11" dietpi1

Deploying a Container to the Remote

Simply create your docker compose file and run: docker-compose --context dietpi1 up -d
