I wrote this gist to record the steps I followed to get docker running in my Raspberry Pi 3. The ARM ported debian version (Jessie) comes with an old version of docker. It is so old that the docker hub it tries to interact with doesn't work anymore :)
Hopefully this gist will help someone else to get docker running in their Raspberry Pi 3.
From original instructions at http://blog.hypriot.com/post/run-docker-rpi3-with-wifi/
sudo apt-get install -y apt-transport-https
wget -q https://packagecloud.io/gpg.key -O - | sudo apt-key add -
echo 'deb https://packagecloud.io/Hypriot/Schatzkiste/debian/ wheezy main' | sudo tee /etc/apt/sources.list.d/hypriot.list
sudo apt-get update
sudo apt-get install -y docker-hypriot
sudo systemctl enable docker
Verifying your docker installation
Once installed run the following verifications.
Confirm that we have the newest version of docker
pi@raspberrypi:~ $ docker version
Client: Version: 1.10.3 API version: 1.22 Go version: go1.4.3 Git commit: 20f81dd Built: Thu Mar 10 22:23:48 2016 OS/Arch: linux/arm Cannot connect to the Docker daemon. Is the docker daemon running on this host?
Remove the error about the docker deamon by adding the current user (pi) to the docker group
pi@raspberrypi:~ $ sudo usermod -aG docker pi
NOTE: After this command, log out and log in as the pi user to refresh your session.
Run ARM version of docker hello-world
pi@raspberrypi:~ $ docker run armhf/hello-world
Unable to find image 'armhf/hello-world:latest' locally latest: Pulling from armhf/hello-world 8c4f258b5966: Pull complete Digest: sha256:bd9444c789932e7525c1f2a78ad2cf261fa4056048fc1ce24adde3b26835a089 Status: Downloaded newer image for armhf/hello-world:latest Hello from Docker. This message shows that your installation appears to be working correctly. To generate this message Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client which sent it to your terminal. To try something more ambitious you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images automate workflows and more with a free Docker Hub account: https://hub.docker.com For more examples and ideas visit: https://docs.docker.com/engine/userguide/
Run an example application and confirm your Pi 3 docker instances are accessible from anywhere in the network.
pi@raspberrypi:~ $ docker run -d -p 8081:8081 resin/rpi-google-coder
Once the container is pulled and started, confirm that it's running
pi@raspberrypi:~ $ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3a163325ba16 resin/rpi-google-coder "/opt/node/bin/node s" 11 minutes ago Up 10 minutes 0.0.0.0:8081->8081/tcp sick_hugle
If you see the above output, our resin/rpi-google-coder container is runing. The app inside is a Node.js application, bound to port 8081 in our Raspberry Pi 3 host via port forwarding.
Now open a browser inside any computer on your network and go to ...
https://<rpi ip address here>:8081
Your browser should load the Coder Node.js application above. You might get an SSL certificate warning, since the URL is HTTPS and the certificate is self signed.
Accessing USB ports from your docker container
If you are like me, and want access to your Arduino from docker containers, run your container with elevated privileges as below.
pi@raspberrypi:~ $ docker run -dti --privileged tyrell/control-things-from-the-internet:rpi-latest
In the above instance, I'm running a container from my repository named tyrell/control-things-from-the-internet. rpi-0.1 is the TAG I used while commiting my docker image to the repository.
TIP: If you are testing a Dockerfile in your mac, before deploying to your RPi, follow https://medium.com/google-cloud/developing-for-arduino-with-docker-and-johnny-five-on-osx-cc6813ae6e9d#.gfuupc8mr to give VirtualBox access to USB ports.
