Docker Compose Service Generator
Every local development stack needs the same backing services, and setting them up identically for every teammate means writing the same compose block over and over. The wrong environment variable name or a missing volume means the container starts but the app cannot connect. This generator produces a correct service block for four common dependencies. One input controls the output: the Service dropdown — PostgreSQL, MySQL, Redis, or MongoDB. Each block includes a pinned image version, the correct environment variables for that image, a published port on the service's standard port, and a named volume so data persists across container restarts. Paste the block into your docker-compose.yml, change the placeholder password, and run docker compose up. Generate multiple blocks and place them under one services heading — they share a default network.

Detailed instructions
- Pick the backing service you need.
- Click Generate to produce the compose block.
- Paste it into your docker-compose.yml.
- Change the password and run docker compose up.
Use Cases
- •Spinning up a database for local development
- •Giving every teammate an identical local stack
- •Remembering the environment keys an image expects
- •Adding a cache or queue to a compose file
- •Running integration tests against a real service
Tips
- →Move passwords to an .env file referenced by the compose file.
- →Add a healthcheck so dependent services wait for readiness.
- →Pin image tags so every machine runs the same version.
- →Use depends_on to order app startup after the database.
FAQ
which services does the generator support
Four: PostgreSQL (postgres:16-alpine), MySQL (mysql:8), Redis (redis:7-alpine), and MongoDB (mongo:7). Each block includes the correct image, environment keys, published port, and a named volume declaration.
why does the block include a named volume
A named volume stores data outside the container filesystem, so stopping or recreating the container does not wipe the database. Without it, every docker compose down would start the service from an empty store.
are the credentials safe for production
No. The passwords are placeholder values for local development only. For any environment beyond your own machine, inject credentials from a secrets manager or env file and never commit real passwords to source control.
can I combine multiple service blocks into one file
Yes. Generate each service block and paste them under a single services: key in one docker-compose.yml, with all named volumes together under a top-level volumes: key. Services in the same compose file share a default network and reach each other by service name.
