Cloud Operations Playbook #5
This lesson focuses on improve incident response speed for a payments processing pipeline environment. You will run commands: git checkout -b feature/ci | docker run -p 3000:3000 app:dev | ls -la. The content is designed for practical DevOps and Cloud execution, not generic examples.
Code Example
version: "3.9"
services:
api:
image: app:latest
ports:
- "3000:3000"
environment:
NODE_ENV: production
APP_SCENARIO: "payments processing pipeline"
healthcheck:
test: ["CMD", "curl", "-f", "http://localhost:3000/health"]
interval: 10s
timeout: 2s
retries: 5
# run: ls -laCommands & References
- git checkout -b feature/ci
- docker run -p 3000:3000 app:dev
- ls -la
Lab Steps
- Prepare tooling and environment with: git checkout -b feature/ci
- Apply infrastructure or deployment change in a safe test environment.
- Validate rollout/health/metrics and document observations.
- Propose one reliability or security improvement for production.
Exercises
- Add one guardrail to prevent faulty deployments.
- Implement one observability signal for faster incident debugging.
- Write a rollback checklist for this scenario.
