3. Why RPi + Docker
1st credit card-sized PC
HW/SW split….
Rapidly develop IoT Apps
Portable WYSIWYR
ARM is Rising!!!

4. GPIO in Docker
Control LED Blinking

5. The Martix of Hell

6. Docker is not Virtual Machine
Operating-system-level virtualization
Chroot + Cgroup + github
Golang
Container engine
Support LXC, Windows container soon

13. Use case
● Databox - Volume container
● Development or Runtime env - Onbuild
● Computing - GPU, GPIO
● Cross-compilers, build container
● Installation container - Cmd, GUI
● CI/CD Service compontents***
● VM style - bad idea

18. FAQ
1. How to build base image? Scratch, Github
2. How to use Boot2Docker? Just use Linux
3. Why Windows support Docker?
4. Why IoT developer must learn Docker?
Device & Cloud use the same SW process
IT careers all need Docker…...
