Ahoy, Developers! 🌟

Ever found yourself juggling with the orchestration of multiple Docker containers? Fear not, for today we embark on an exhilarating journey into the magical realm of Docker Compose! 🎉 Brace yourselves as we simplify the complex and spice it up with a hands-on adventure.

Unleashing Docker Compose Magic

Imagine a tool that could define and manage your entire app stack with just a single command. Enter Docker Compose! 🚀 Armed with a simple YAML file - docker-compose.yml - we wield the power to control our containerized world effortlessly.

Crafting our Docker Symphony 🎶

Let’s dive right into it. Create a file named docker-compose.yml and sprinkle it with the following magic:

version: '3'
services:
  web:
    image: nginx:latest
    ports:
      - "8080:80"
  db:
    image: postgres:latest
    environment:
      POSTGRES_PASSWORD: example

Two services, web and db, dance together. The web service, donned in the latest Nginx attire, grooves on port 8080, inviting you to the party. Meanwhile, the db service, a PostgreSQL virtuoso, guards its secrets with a sly password.

Get Your Hands Dirty! 🛠️

Task-1: Enviro-Magic Setup

Time to get hands-on! Use docker-compose.yml to set up an environment that'll make Houdini jealous. Create links between containers, weave networks, and let environment variables do the talking.

Task-2: Docker Dance Moves

1. Pulling the Image: Channel your inner magician; pull a Docker image from the mystical Docker Hub using the spellbinding docker pull command.

2. Non-root Wizardry: Run the container as a non-root wizard. Grant permissions with the mighty usermod command, and reboot the instance for the magic to take hold.

3. Inspecting the Invisible: Peer into the unseen! Use docker inspect to reveal the container's hidden processes and exposed ports.

4. Log Book of Spells: Open the log book with docker logs and decipher the mystical messages from within the container.

5. Start, Stop, and Poof! 💨 Play with the container's life force. Command it to halt (docker stop) and rise again (docker start). Finally, bid it farewell with a docker rm spell.

No More sudo Sorcery

Tired of the sudo sorcery dance? Liberate yourself! Ensure Docker is installed, let the system update its charms, and recite:

sudo usermod -a -G docker $USER
# Reboot the machine
