Topics

1. Docker?

   • What is Container?

   • Language Flexibility

     service A(jdk8), service B(jdk7), service C(go1.9)

   • Isolation Without Overhead

     light weight

   • Developer Efficiency

     Isolating Dependencies(libs, configuration)

   • Reproducibility

     Containers make it easier to reproduce your application environment.

2. Getting Start

   • Install Docker and Editor

     1. get-docker
     2. install windows home
        WSL2 must be installed before you can install and use Docker.
     3. Install VSCode & Docker Plugin

   • Hello World Docker

     docker run hello-world

   • Docker run: behind the scenes

     • Docker looks for the image on this computer
     • Is it installed
     • Docker searches Docker Hub for the image.
     • Is it on Docker Hub
     • Docker downloads the image
     • The image layers are installed on the computer
     • Docker create a new container and starts the program.
     • The container is running.

3. Docker Commands
