5. WHAT IS DOCKER?

6. PACKAGE YOUR APPLICATION INTO A
STANDARDIZED UNIT FOR SOFTWARE
DEVELOPMENT
Docker containers wrap a piece of software in a complete filesystem
that contains everything needed to run: code, runtime, system tools,
system libraries – anything that can be installed on a server. This
guarantees that the software will always run the same, regardless of its
environment.

7. - Lightweight
- Open
- Secure by default
ADVANTAGES OF DOCKER

8. COMPARING
CONTAINERS AND
VIRTUAL MACHINES

9. VIRTUAL MACHINES
Virtual machines include the
application, the necessary
binaries and libraries, and an
entire guest operating system --
all of which can amount to tens
of GBs.

10. DOCKER (CONTAINERS)
Containers include the application
and all of its dependencies --but
share the kernel with other
containers, running as isolated
processes in user space on the
host operating system. Docker
containers are not tied to any
specific infrastructure: they run on
any computer, on any
infrastructure, and in any cloud.

15. 2. DOCKER TOOLBOX

16. WHAT’S IN THE TOOLBOX
- Docker Engine
- Docker Compose
- Docker Machine
- Kitematic

17. KITEMATIC
- Docker GUI
- Fast and Easy Setup
- Docker Hub Integration
- Seamless Experience Between
CLI and GUI

18. 3. DOCKER FOR MAC/WINDOWS

19. WHAT’S IN DOCKER FOR MAC/WINDOWS
- Docker Engine
- Docker CLI Client
- Docker Compose
- Docker Machine

20. HOW TO DOCKERIZE
WORDPRESS?
For development only (without Docker Compose)

21. DOCKERFILE, DOCKER IMAGE,
AND DOCKER CONTAINER
- Write Dockerfiles
- Build Docker images from Dockerfiles
- Run Docker containers from Docker images

22. WHAT DO WE NEED IN DOCKER IMAGES
- Web server
- PHP
- MySQL
- WordPress Core
- WP-CLI (recommended)

23. BEST PRACTICES FOR WRITING DOCKERFILES
- Containers should be ephemeral
- Use a .dockerignore file
- Avoid installing unnecessary packages
- Run only one process per container
- Minimize the number of layers
- Sort multi-line arguments
- Build cache

24. FROM A DOCKERFILE
https://github.com/wckr/wordpress-dockerfile
$ docker build https://github.com/wckr/wordpress-dockerfile.git

25. FROM DOCKER HUB

26. DOCKER HUB
Docker Hub is a cloud hosted
service from Docker that provides
registry capabilities for public and
private content.

27. USING DOCKER CLI
$ docker pull wocker/wordpress

28. FROM KITEMATIC
