3. Agenda
- Why the IOT Needs Docker?
- How to setup Docker Swarm Cluster on
Raspberry Pi
- Docker Container for Raspberry Pi to Blink
an LED
- Questions?

4. Why the IoT Needs Docker?
- Minimal hardware resources.
- Geographic distribution.
- Limited or sporadic network access
- Widely varying device environments.

5. How to setup Docker Swarm
Cluster on Raspberry Pi?

6. Docker Container for
Raspberry Pi to Blink an LED
- Install Docker on Raspberry pi
sudo apt-get update && sudo apt-get upgrade
curl -sSL https://get.docker.com | sh
sudo usermod -aG docker your-username

7. Prepare the Circuit:

8. Clone repo
Git clone https://github.com/sangam14/Docker-IOT-rpi.git
$ cd Docker-IOT-rpi
Docker-IOT-rpi $ ls
Dockerfile ledblinker.py readme.md

9. ledblinker.py

10. Dockerfile
# Python Base Image from https://hub.docker.com/r/arm32v7/python/
FROM arm32v7/python:2.7.13-jessie
# Copy the Python Script to blink LED
COPY led_blinker.py ./
# Intall the rpi.gpio python module
RUN pip install --no-cache-dir rpi.gpio
# Trigger Python script
CMD ["python", "./led_blinker.py"]

11. docker-build

12. Run Container
pi@raspberrypi:~/docker-ledblink $ docker container run --
device /dev/gpiomem -d docker_blinker:v1
OR
docker container run --privileged -d docker_blinker:v1

13. Demo

14. You should see it
successfully Running
Cheers !
Stop container :-
docker stop $(docker ps -a -q)
