Docker Compose Explained | Run Multi-Container Apps with One Command (Episode 7)
на канале: Enhancerworx IT Tutorials
In this video, you’ll learn how to use Docker Compose to manage multi-container applications efficiently.
As your apps grow, running multiple containers manually becomes messy and error-prone. Docker Compose solves this by letting you define your entire application in a single YAML file — and run everything with one command.
We’ll cover:
Why Docker Compose is essential
The problem with managing multiple containers manually
Structure of a docker-compose.yml file
Understanding services, volumes, and networks
Running a real-world app (Flask + Postgres + Redis)
Using depends_on to control startup order
Automatic networking (service name = hostname)
Persisting data with volumes in Compose
Essential commands you’ll use daily:
docker compose up -d
docker compose logs -f
docker compose down
docker compose up --build
By the end of this video, you’ll be able to run complex multi-container applications with a single command.
