Learn Docker 🐳

• Hands-on repository to learn about Docker

Getting Started

Run on Playground

• No installation need, just use the sandbox!

Local Development

WSL Installation

• Before you can setup Docker on your local machine, you need to setup Windows Subsystem for Linux (WSL) in order to install Docker. See WSL installation guide

Docker Installation

• Install Docker See Docker installation guide

Let's Dock!

1. Git clone this repository in Docker Sandbox.

2. cd into /learn_docker.

3. Build Docker image with the following command

   docker build -t hello-docker .
   

   Don't forget to put the period at the end of the command! Wait a couple of seconds before the image is completely build.

4. Check whether the image has been build with

   docker image ls
   

   The following output should shown

   REPOSITORY     TAG       IMAGE ID       CREATED          SIZE
   hello_docker   latest    5c8a423dfed9   16 minutes ago   222MB
   

5. Spin the new container from the image with

   docker run hello_docker 
   

6. The following output should shown

   hello wei
   hello wei
   hello wei
   

7. Show all container with command

   docker ps -a
   

   Output will show the existing container

   CONTAINER ID   IMAGE          COMMAND                  CREATED
   8a203ca5aa3d   hello_docker   "/bin/sh -c 'python …"   5 seconds 
   

8. To delete the container, run command

   docker rm 8a203ca5aa3d
   

   docker rm <container_id>

9. After than you can delete the image with

   docker rmi 5c8a423dfed9
   

   docker rmi <image_id>

NOTE: To delete image, you need to delete the container first (due to container is the runnable instance of image)

10. Congratulation you has successfully build with Docker! 🐳🎉
