🚀 TL;DR - Docker
Wow, you don’t know yet what is Docker? Well, let me introduce you this beautiful containerization tool.
- Container ~= virtual machine
A container is like a virtual machine that runs in background on your computer. It simulates a whole system in the same way.
- Container > virtual machnie
But, a container is faster, better
and stronger than a classical VM. Because it is meant to be fast and light-weight.
Docker uses images to run containers. In short an image is a base container, which will be used by your container – like said – as a base. For example, I want to run an Ubuntu container, my Docker image will be something like:
This file is called a Dockerfile, because it produces the corresponding Docker container when built.
When ran, this image will use the latest Ubuntu image in Docker’s database, amd update it.
You can do so much in a Docker image!
Build & run
Once you made your Dockerfile, you will use it to build your Docker image:
-t my-image: the tag (or name if you want) to give to your image
.: the directory where you put your
You now want to run it!
And, voila! Your container is running!
docker ps: list all running containers
docker inspect: get information about a given container
docker kill: kill a running container
docker images: list all stored Docker images
