L3 Why use Docker?

# This is at its core what Docker is trying to fix

# on Web servers as well, or any cloud based computing platform

# Install a piece of software called Redis (in memory data store)

# one signle command

L4. What is Docker?

# e.g, I use Docker on my project, they might be reference to Docker client or Docker Server

Again, these are all projects, tools, pieces of software come together to form a platform or ecosystem around creating and running something called containers

What is containers?

# docker run redis ( examine that entire series of actions very closely over time）

 -> Reach docker Hub

 -> Download a single file called an image ( in your hard drive)

# The container is a program with its own isolated set of hardware resources ( kinds of has its own little set or its own little space of memory / hard drive / networking technology)

Two terminology

# docker image

# container

L5. Docker for Mac / Window

# Docker client itself doesn't actually do anything with container or images

# a tool help us interact with another piece of software (Docker server)

# Docker Server - tool that responsible for creating container's image, maintaining container, uploading images and doing just about everything you can possibly imagine around the world of Docker

L6. Installing Docker on MacOs
