Deployments

Concept & How It Works

    Why Does It Exist?

    Local demos ≠ production. Deployment covers env vars, secrets, health checks, rollbacks, and zero-downtime updates.

    Real-World Analogy

    Deployment is moving from cooking at home to opening a restaurant — same recipe, but health inspections, staff, and supply chains matter.

    What is Deployments?

    Example

    Scenario

    Merge to main triggers GitHub Actions: test → build image → deploy to staging → run eval suite → promote to prod.

    Solution

    In Production Agent Engineering, apply Deployments to this scenario: Merge to main triggers GitHub Actions: test → build image → deploy to staging → run eval suite → promote to prod. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.

    Practice Task

    Do this before moving to the next module — reading alone is not enough.

    Open the Code Walkthrough below and run it locally. Change one parameter related to Deployments (e.g. model, temperature, top_k, or tool name), observe the difference in output, and write 2–3 sentences explaining what changed.

    Commands to Remember

    Commands to Remember

    • pip install fastapi uvicorn # serve agent APIs
    • docker build -t agent-api . # containerize for production
    • kubectl apply -f deployment.yaml # deploy to Kubernetes

    Common Mistakes

    • Treating Deployments as a black box without evaluation
    • Ignoring cost and latency in production
    • Skipping error handling for deployments
