Context

docker-compose.yml embeds postgres:postgres credentials in plain text. This is a security risk — credentials should never be committed to version control.

Task

  • Create a .env.example file with placeholder values for POSTGRES_USER, POSTGRES_PASSWORD, DATABASE_URL, and other sensitive variables
  • Update docker-compose.yml to reference these variables using ${POSTGRES_USER} syntax instead of hardcoded values
  • Add .env to .gitignore if not already present
  • Update README or developer docs with setup instructions

Acceptance Criteria

  • docker-compose.yml contains no plaintext passwords
  • .env.example exists with all required variable names and placeholder values
  • .env is in .gitignore
  • docker compose up still works correctly when a .env file is present

Already implemented on main. docker-compose.yml uses ${POSTGRES_USER}, ${POSTGRES_PASSWORD}, ${POSTGRES_DB} variable substitution -- no plaintext credentials. .env.example exists with placeholder values. .env is in .gitignore. All acceptance criteria met. Closing.
