Docker Containerization

Learn how to containerize your applications using Docker. This tutorial covers the fundamentals of Docker, including images, containers, Dockerfiles, and Docker Compose. You'll understand how to build, run, and manage isolated environments for your applications, making deployment easier and more consistent.

Key topics include:

• Docker installation and setup
• Creating Dockerfiles
• Managing Docker images and containers
• Orchestration with Docker Compose

What is a Container?

A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container is a lightweight, standalone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries and settings.

Basic Docker Commands

Here are some fundamental Docker commands you'll use regularly:

docker pull ubuntu:latest      # Pull an Ubuntu image
docker run -it ubuntu bash     # Run a container from the image
docker ps                      # List running containers
docker stop [container_id]     # Stop a container
docker rm [container_id]       # Remove a container
docker images                  # List all images

Mastering Docker will significantly streamline your development and deployment workflows!
