A Simple Docker Demo

Docker

Hey, guys.

I'm Ricky, a college student majoring in Computer Science. 🧑🏻‍💻

Recently, I have been learning Docker and I came across Docker Crash Course for Absolute Beginners on YouTube. I found this tutorial to be an excellent resource for anyone who is just starting out with Docker.

I really appreciate the way TechWorldwithNana teaches in the video. So I decide to share it with you. 😊

In this repository, I have listed the learning resources I use and my personal notes about it .

I hope this will be helpful for your understanding of Docker. 😄

Notes

• Basic Concepts of Docker
  • Image
  • Container
  • Registry
• Basic Docker Command Line
  • Image
    • docker build -t [image_name] [directory_of_dockerfile]
      • build dockerfile to image
    • docker images
      • show all the images you have on your local machine
    • docker pull [image_name]:[version]
      • pull a image from registry
  • Container
    • docker ps && docker ps -a
      • show all the containers you have on your local machine
    • docker run --name [container_name] -d -p [host port]:[container port] image_name
      • create a container based on a image ( -d → run it in background; -p → port binding)
      • 🍉 PS: Every time you use docker run, it will create a container. So if you want to re-run the existed containers, use docker start instead
    • docker logs [container_id / name]
      • logs about container
    • docker stop [container id / name]
      • stop running this container
    • docker start [container id / name]
      • start running this container
• Hands-on Demo
  • Clone the demo repository (Crash Course Repo)
  • Test this code using Docker
    • Learning how to write Dockerfile
    • Use docker build -t [image_name] . to build Dockerfile to Docker image
    • Create a container based on that image
    • Open localhost:3000 on web browser to check if the container is working properly
