I develop web apps, digital tools and full projects — from design to deployment.
The docker-compose.yml file defines every container in a local project — database, cache, backend — and how they connect to each other. Writing it by hand usually means digging through each image's docs for the required environment variables, exposed ports and data paths. This generator ships the most common services already configured with their correct values: pick a preset, tweak what you need (name, ports, vars, restart policy) and declare dependencies between containers to control startup order. Named volumes are declared on their own in the final YAML's volumes section.
Features
- ✓PostgreSQL, MySQL, MariaDB, Redis, MongoDB and Nginx presets
- ✓Ports, volumes and env vars per service
- ✓depends_on by selecting services
- ✓Named volumes declared automatically
- ✓Ready-to-copy YAML
How to generate a docker-compose.yml?
- 1
Add your services
Start with a database or cache preset and add what you need.
- 2
Tune each service
Name, image, ports, volumes, env vars and restart policy.
- 3
Declare dependencies
Check depends_on so the database starts before your app.
- 4
Save and run
Copy the content into docker-compose.yml and run "docker compose up -d".
Frequently asked questions
Do I need the version: key in my compose file?
No. The current Compose specification has deprecated version: for years; modern files start directly with services:. If you run a very old version you'll get a warning anyway.
How do the containers talk to each other?
Compose creates a shared network where each service resolves by name: if your database is named db, your app can use host db with the internal port (5432), even without publishing that port externally.
Is everything generated in my browser?
Yes, the YAML is composed locally. No configuration is uploaded.
