for some reason im just having a moment trying to understand docker.

I understand the difference between
Dockerfile: Instructions on how to create an image
Image: an immutable "state" of the initial application
Container: a running version of an image
Volume: a shared storage module that can be used by running containers

Questions

  • How does a docker compose work?
  • How do i setup a devcontainer in vscode?
  • How does the file system work in a devcontainer: does it use a docker volume, or does it attach to my exisiting windows file system?

Main Goal

1.) Get a Dockerfile pushed to the github repo, so my friend can use docker compose up to spin up a running version of the application in a container
2.) Setup a devcontainer that is also stored in the github repo, and creates a consistent development environment for both of us. This environment includes:

  • Certain extensions in the container (ex. eslint, prettier)
  • Certain vscode settings (nothing personal, ex. eslint.fixAll on save)
    3.) The ability to debug properly, using vscode breakpoints, watchers, etc, while inside the devcontainer

Notes

  • This will be stored in the cloud on github
  • I will be collaborating with another individual on this project

In terms of my main goal, how would i setup my Dockerfile, docker-compose, and devcontainer in my file system, so that i can push it to github and we can share the same environments
