Day 18 Task: Orchestrating Containers with Docker Compose 🚢

Hey, fellow DevOps enthusiasts! Today's #90daysofdevops task had me harnessing the power of Docker Compose. It's all about connecting the dots, or rather, containers. 🐳💡

The Lowdown on Docker Compose 📜

Docker Compose is like the conductor of an orchestra, ensuring all containers work in harmony.

Compose Your Symphony: With a docker-compose.yml file, I defined my multi-container setup like crafting a musical score.
The YAML Maestro: The .yml file format is the sheet music Docker Compose reads from – clean, structured, and intuitive.

What's YAML? 🤔

YAML (either "Yet Another Markup Language" or "YAML Ain't Markup Language") is the go-to for config files:

User-Friendly: It's easy on the eyes and simple to understand.
Versatile: .yml or .yaml, it's all about structured data that's a breeze to read and write.

Task-1: Setting the Stage with `docker-compose.yml` 🎭

Dove into docker-compose.yml, where I specified my Django app services.
Configured my web service, linked it to a database, and set environment variables without exposing them.
Here's a snippet:
With a single docker-compose up, my app danced to life.

Task-2: Running Containers Like a Pro 🏃‍♂️

Pulled an image from Docker Hub and ran it locally, making sure to use a non-root user for security.
Played detective with docker inspect to understand my container's inner workings.
Listened to the heartbeat of my container using docker logs.
Practiced my container start/stop routine with docker stop/start.
And finally, bid farewell to my container with docker rm.

Bonus: Dropping the `sudo` 🛑

Learnt that adding my user to the docker group lets me run Docker commands without the sudo prefix. It felt like unlocking a new level in a game!

sudo usermod -aG docker $USER
Just remember to reboot your machine after this change.

Wrapping Up Day 18 🌟

Today, Docker Compose lifted the veil on container orchestration, revealing a world where everything clicks into place with ease.
