rh02/rpi-python repository overview

⁠RPi3-python

Docker container with python Environment for raspberry-pi3

⁠Install Stable Docker Community Edition

For RaspberryPi3: https://www.raspberrypi.org/blog/docker-comes-to-raspberry-pi/⁠

⁠Running container for the first time

First run docker pull rh01/rpi-python to pull the latest version of image. Run using docker run -it --name pythonenv1 rh01/rpi-python. This command downloads the prepared image from a public hub, and starts a bash for you.

⁠Stopping and starting the container

This "stop and start" scenario is useful when you want to take a break and turn off your host machine.

⁠Stopping the container

Save your work inside the container, then run docker stop pythonenv1 in different terminal window to stop a running container. You will be able to start it later.

⁠Starting container after stopping

Run docker start -a pythonenv1 to run previously stopped container and attach to its stdout. You can continue to work where you left off.

⁠Container checkpoints

You might want to make a checkpoint of your work so that you can return to it later. Think of it as a backup or commit in version control system.

⁠Saving container state

You will first have to stop the container following instructions above. Now you need to save the container state so that you can return to it later: docker commit pythonenv1 pythonenv1-snap. You can make sure that it's saved by running docker images.

⁠Creating new container from previous checkpoint

If you want to continue working from a particular checkpoint, you should run a new container from your saved image by executing docker run -it --name pythonenv2 pythonenv1-snap. Notice that we incremented index in the container name, because we created a new container.
