2 likes448 views
This document discusses Docker, an open-source containerization platform. It begins with a comparison of Docker containers to virtual machines, then describes the Docker architecture including Dockerfiles, images, and containers. Several examples are provided of using Docker to quickly launch servers, compile modules, and build Linux applications. Limitations of Docker on Windows and Mac are noted. The document concludes with recommendations on using Docker for continuous integration, keeping host environments clean, and sharing build environments between colleagues using Dockerfiles.

- 1. Introduction Docker for Hardware Company Evan Lin
- 2. Agenda ❖ Comparison between Docker and VM ❖ Docker Architect ❖ Some examples ❖ Limitations ❖ How to use docker in our daily work ❖ Q&A
- 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 http://evan:49002 http://evan:49001 49002:8049001:80 < 1 Second !
- 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.
