❖ Comparison between Docker and VM
❖ Docker Architect
❖ Some examples
❖ Limitations
❖ How to use docker in our daily work
❖ Q&A

8. Docker Architecture

9. Docker
Dockerfile
Docker
Image
containerbuild run
download image
update

10. Some examples
❖ Run docker for launch server in second.
❖ Run docker for compiling modules
❖ Build docker image and run container

11. Example 1: Establish a LAMP in second
docker run -d -p 49001:80 dockerfiles/centos-lamp

12. Example 1.5: Run second LAMP in the same computer
❖ How much time do we need to launch second LAMP
server in VM?
❖ How much time do we need to launch second LAMP
server in Docker?

13. Example 1.5: Run second LAMP in the same computer

14. Run VM for compiling modules
PHP 5
Python2
Python3
GCC 4.8
GCC 5.2
PHP 7
Original way in VM

15. Run docker for compiling modules
New way in Docker
gcc 5.2gcc 4.8
resultresult

16. Run docker for compiling modules
New way in Docker
Ubuntu 15.01 g++ cmake
mount volume
Windows 10

17. Build docker image and run container
Dockfiles Image Container

18. Build docker image and run container (ex: Linux App)
write Dockfiles
run image as Container
build docker Image

19. Build docker image and run container (ex: Linux App)
run sh in Docker Container

20. Limitations
❖ No Windows/Mac Image and Container for now
❖ Run on Windows/Mac will launch another ubuntu VM
which still limited its memory and CPU

21. How to use docker in our daily work
❖ Using dockerfile to store image in Gitlab for CI
❖ Ensure your computer (Host) stay in clean stage
❖ It is very easy to deliver build environment to another
college/vendor by passing dockerfile.

22. Example: Ensure isolate host environment
gcc 5.2gcc 4.8 gcc + Android NDK Go 1.5
Ubuntu 15.01 + Only install Docker

23. Example: Use docker in JNI C++ Library
Original way
Ubuntu 15.01
Android NDK
Cmake
g++

24. Example: Use docker in JNI C++ Library
Ubuntu 15.01 + Android NDK
Ubuntu 15.01 + cmake + g++
New way in Docker

25. Example: Use docker in JNI C++ Library (Dockerfile)
Dockerfile: Ubuntu 15.01 + cmake + g++
