Docker image scripts for ev3dev

Ev3dev Docker Library

This repository is used to create the official ev3dev docker images.

Image Variants

There are many images. Here's how to sort them out.

• The image names follow the pattern ev3dev-<dist>-<hardware>-<variant>.
  • <dist> is the Debian distribution it is based on, e.g. jessie, stretch...
  • <hardware> is the hardware platform, e.g. ev3 for LEGO MINDSTORMS EV3, bone for BeagleBone, rpi for Raspberry Pi 0/1 and rpi2 for Raspberry Pi 2/3.
  • <variant> describes which extra packages are installed. base is a minimal system. generic is what is used for the official image releases.

Using the Images

• First, you will need to install Docker Engine on your system.

• Then grab an ev3dev image:

    docker pull ev3dev/ev3dev-jessie-ev3-base
  

• Make a shorter name for the image:

    docker tag ev3dev/ev3dev-jessie-ev3-base ev3
  

• You can start a shell as the robot user in the image:

    docker run --rm -it ev3 su -l robot
  

• But, the main purpose of these Docker images is to create bootable SD card images using the brickstrap tool.

    brickstrap create-tar ev3dev/ev3dev-jessie-ev3-generic ev3dev.tar
    brickstrap create-image ev3dev.tar ev3dev.img
  

Tips

• You can use a specific version of an image by adding a "tag" to the name:

    ev3dev/ev3dev-jessie-ev3-base:2016-08-11
