The slide introduces what problem the Docker solves in higher level view. Not the step by step tutorial.

1. Introduction to Docker @brownylin
2. Dilemma 1
3. Not works on my machine Works on my machine Works yesterday Did you change something?
4. Reproducible matters!!
5. Dilemma 2
6. 開發者(Developer) Build once...run anywhere 運營者(Operator) Config once...run anything
7. The Boss ? Fix it, and ASAP 給我搞定, 而且愈快愈好
8. Server = Development + Operation = DevOps
9. Separate of Concern matters!!
10. Dilemma 3
11. Performance matters!!
13. The Docker Is A reproducible, separation of concern and well performed Abstraction for Developers & Operators

18. Docker compile(Car car) Docker compile(Piano piano) ... transportByTruck(Docker car) transportByShip(Docker car) …
19. 開發者煩惱 app 怎麼在 docker 內運行 運營者煩惱 docker 如何跟 host 溝通
20. Interface Docker { void dependency(); // for Developer void runtime(); // for Operator } The Docker Is nice interface
22. How does Docker work 1. Dockerfile (Infrastructure as Code) 1-1. Describe the composition of environment 1-2. Describe the service it provides 2. Docker daemon (receive the Docker cli, client- server arch.) 3. Docker command line
23. Conclusion 1. Docker is not only for deployment, it is also a working- style 2. Run successfully once here, run successfully anytime/anywhere 3. Infrastructure as code, and it could be version controlled 4. Easier to scale out
