How do I add more than one service?

Click Add service to append another service block, configure its name, image, ports, and other fields, and it appears in the YAML immediately. You can remove any service (when more than one exists) with its trash button, and reorder your stack by editing the blocks.

Can I use a custom image instead of a preset?

Yes. The Image dropdown offers common images grouped by category plus a "Custom image…" option. You can also leave the image blank and provide a build context path instead, which generates a build: entry so Compose builds the image from your Dockerfile.

How are multi-line fields like ports and environment handled?

Fields such as Ports, Volumes, Environment variables, Depends on, and Networks accept one value per line — for example "3000:3000" then "8080:80" for ports, or "NODE_ENV=production" then "PORT=3000" for env vars. Each non-empty line becomes a separate list entry under that service in the YAML.

What do the top-level volumes and networks fields do?

They declare named volumes and networks at the root of the Compose file (one per line). Named volumes give you persistent storage that survives container restarts, and defining networks lets you group and isolate which services can talk to each other.

Is the configuration saved between sessions?

Yes. The entire Compose configuration — version, services, volumes, and networks — is stored in your browser’s local storage and restored when you return. Use Reset to clear it, and copy or download the output as docker-compose.yml when finished.

Generate Docker Compose configurations for multi-container applications with common stacks and services

About this ToolHow it works, benefits & use cases

Define a multi-container stack service by service and this tool emits a valid docker-compose.yml as you go. Set the global Compose version and declare top-level named volumes and networks, then add as many services as you need. Each service has a name and either a pre-set image (chosen from common images grouped by category) or a custom image, plus a build context, restart policy (no, always, on-failure, unless-stopped), and multi-line fields for ports, volumes, environment variables, depends_on entries, networks, and a command override. Quick-start templates seed common stacks so you are not starting from a blank file, and the YAML preview rebuilds live as you edit. Add and remove services freely, and the whole configuration persists in your browser between visits. When the stack looks right, copy it or download it directly as docker-compose.yml.

How to Use

1Optionally pick a quick-start template to seed a common stack, then set the Compose version.
2Declare any top-level named volumes and networks in the Global configuration fields.
3For each service, set its name and image (or a custom image / build context) and a restart policy.
4Fill in the multi-line Ports, Volumes, Environment, Depends on, and Networks fields, plus an optional command override.
5Use Add service for more containers, then copy or download the generated docker-compose.yml.

Key Benefits

Builds docker-compose.yml for multi-container stacks one service at a time
Quick-start templates seed common stacks instead of a blank file
Common images grouped by category, or supply your own custom image
Per-service ports, volumes, env vars, depends_on, networks, and command override
Restart-policy selector (no, always, on-failure, unless-stopped) per service
Top-level named volumes and networks for persistence and isolation
Live YAML preview, local persistence, and one-click download

Common Use Cases

Standing up an app-plus-database stack (e.g. web service with PostgreSQL and Redis)
Generating a Compose file for local development from a curated template
Wiring service startup order with depends_on and isolating traffic via networks
Adding persistent named volumes for databases and caches
Sharing a reproducible multi-service environment as a downloadable docker-compose.yml

Quick start templates

Service 1: app

Service name

Image

Build context (optional)

Restart policy

Ports (one per line)

Updates live as you edit the configuration above

version: '3.8'

services:
  app:
    image: node:20-alpine
    container_name: app
    restart: unless-stopped
    ports:
      - "3000:3000"

Docker Compose best practices

Use named volumes for persistent data
Define networks to isolate services
Use environment variables via .env files
Set proper restart policies for production
Use depends_on to control startup order
Add healthchecks for critical services
