Docker in docker
One way to enable a docker container to use docker, is to pass the socket for the docker daemon to the container. To make it work you need to:
1. use a container that has the docker cli installed. A dockerfile for that
FROM debian
RUN apt-get update && apt-get install wget -y
RUN wget https://get.docker.io/builds/Linux/x86_64/docker-latest -O /bin/docker
RUN chmod +x /bin/docker
2. mount the docker daemon socket when the container is started docker

The status and remaining time is pulled in from octoprint by the client. An image is taken from a webcam and added as background for the widget.

Add to your dashboard

  <div data-id="octoprint" data-view="Octoprint" data-title="3D printer"></div>
</li>
