What is this?
Docker Compose defines multi-container apps in YAML for local and simple deployments.
Why should you care?
CloudVerse developers run API + Redis + DB together with one command.
See it live — copy this example
Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.
services:
api:
image: cloudverse/api:1.0.0
ports: ["8080:8080"]
environment:
ConnectionStrings__Redis: redis:6379
depends_on: [redis]
redis:
image: redis:7-alpineWhat happened?
- Compose is for local/dev and small hosts — not a substitute for Kubernetes at scale.
- Keep secrets out of git.
Practice next
- Write compose.yml.
- docker compose up.
- Hit API and redis ping.
- Add a db service.
- Use .env for local secrets.
Remember
Multi-service YAML. One command up. Dev ≠ prod orchestrator.
CloudVerse local stack
API+Redis via Compose.
Outcome: Devs share the same lab setup.
