HOW MANY PEOPLE

HAVE USED DOCKER?

WHAT IS DOCKER?

PACKAGE YOUR APPLICATION INTO A

STANDARDIZED UNIT FOR SOFTWARE

DEVELOPMENTDocker 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.

- Lightweight- Open- Secure by default

ADVANTAGES OF DOCKER

COMPARING

CONTAINERS AND

VIRTUAL MACHINES

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

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.

2. DOCKER TOOLBOX

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

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

CLI and GUI

3. DOCKER FOR MAC/WINDOWS

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

HOW TO DOCKERIZE

WORDPRESS?For development only (without Docker Compose)

DOCKERFILE, DOCKER IMAGE,

AND DOCKER CONTAINER- Write Dockerfiles- Build Docker images from Dockerfiles- Run Docker containers from Docker images

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

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

FROM A DOCKERFILE
