3. WHAT IS DOCKER

4. Build, Ship, Run
An open platform for distributed applications for developers and sysadmins
Docker uses resource isolation features of the Linux kernel.
Docker allows you to package an application with all of its dependencies into a standardized unit for
software development
Lightweight
Open
Security

5. How to work with Linux Kernal

6. Different from VM
Containers have similar resource isolation and allocation benefits as virtual machines but a different
architectural approach allows them to be much more portable and efficient.

7. Dockerfile
Docker can build images automatically by reading the instructions from a Dockerfile.
A Dockerfile is a text document that contains all the commands a user could call on the command line to
assemble an image.
Using docker build users can create an automated build that executes several command-line instructions in
succession.

8. Docker Hub
The Docker Hub is a cloud-based registry service for building and shipping application or service containers.
https://hub.docker.com/

12. WHAT CAN DOCKER DO

13. Docker User Cases

14. Benefits from Docker
Accelerate Developer Onboarding
Empower Developer Creativity
Eliminate Environment Inconsistencies
Easily Share and Collaborate on Applications
Ship More Software Faster
Quickly Scale
Easily Remediate Issues

15. Scenario : New Comer on Board(Now)
Install VS
Prepare development environment
Install DB(MSSQL, Oracle)
Install IIS feature
Install Redis, MongoDB
Install Jenkins
Install Task runner(Grunt/Gulp)
Install other(NodeJS, Nginx, Elastic Search, etc…)
Start domain training

16. It is Annoying…

17. Scaenario : New Comer on Board(Docker)
Install VS
Docker Install & Run
Start domain training
Faster and more Simple

18. Scenario : Continuous Integration (Now)
Commit code to DEV SVN
Build DEV SVN
Test in DEV SVN
But Broken another function or some urgent issue interrupted development

19. WTF…

20. Scenario : Continuous Integration (Docker)
Develop in Local
Build in Local
Test in Local
Consistent the
tools and environments

23. Docker on Windows
Windows Server 2016 and System Center 2016 support
Windows Server Container
Boot2Docker(for Windows & Mac)
Lightweight Linux distribution based on Tiny Core Linux made
specifically to run Dockercontainers.
RAM, weighs ~27MB
Boots in ~5s

24. Docker Toolbox
Required
Enable Virtualization Technology on Bios
Install Git(Docker Toolbox including it)
Download Docker Toolbox
Docker terminal
Kitematic(GUI tool)
First launch Docker terminal or Kitematic have problem please remove default VM and create a new one
1. docker-machine rm default
2. docker-machine --native-ssh create -d virtualbox

25. Play with Docker Toolbox - Docker terminal
1. Create a Docker container from Dockerfile
2. Build Instance
docker build -t <your username>/redis .
3. Run the service
docker run --name redis -d <your username>/redis
Docker terminal

26. Play with Docker Toolbox - Kitematic
1. Open Kitematic(Docker GUI tool)
2. Download service for Docker Hub
3. Run the service
4. Enjoy it
Kitematic
