Docker Compose for Local Multi-Service Development

<p>Follow Priya Deshmukh, a backend engineer at feedback-analytics startup Wrenfield Analytics, as she replaces a fragile, hand-run onboarding process with a single docker-compose.yml. Across three lessons she wires a web API to a health-checked Postgres database, builds a live-reload local workflow with bind mounts and an override file while adding a Redis cache, and brings the stack in line with production through matched environment variable names, a .env file, and diagnosing a real service-to-service networking bug.</p>
