Learning Docker
Docker is a tool that lets you package an application and everything it needs (code, libraries, dependencies, settings) into a single unit called a container.
A container can run on any computer that has Docker installed, so your app will work the same everywhere — no “it works on my machine” problem. In short: Docker = box for your app + all its stuff → runs anywhere the same way.
Docker Images : Executable files -> Instructions To Build Containers
Docker Hub : Somewhat like Github but for Docker -> Collection of docker images
We can create multiple containers from one docker image .
Command to See All our images : docker images
docker pull image_name
docker run image_name -> converts image to container
