Docker Compose and .env Workflow for Local Development

Local stacks are easier to maintain when docker-compose.yml describes services and .env.example documents configuration without real secrets.

Workflow

  1. Choose the closest starter stack and generate docker-compose.yml.
  2. Generate a matching .env.example with placeholders for app, database and API settings.
  3. Keep real .env files out of Git and commit only sanitized examples.
  4. Run docker compose up -d, then inspect logs before debugging application code.
  5. Document any port, volume or service-name changes in the repository README.

Checks before production

  • Do not reuse starter database passwords in production.
  • Use persistent volumes for databases that should survive container restarts.
  • Avoid exposing internal services directly to the public network.
  • Keep service names stable so app connection strings stay predictable.

FAQ

Should .env be committed?

Real .env files should not be committed. Commit .env.example with placeholders instead.

Is generated Compose production ready?

No. Treat it as a local development starter and review it before production.
