Practice Task

Scaffold a Service Template

A golden path starts as a template repository: everything a new service needs, pre-wired. Scaffold one — structure, Dockerfile, CI workflow — exactly like a platform team would ship it.

TOPIC 02

Service Catalog

If it isn't in the catalog, it doesn't exist.

Guided Task

Register a Service in the Catalog

Backstage-style catalogs read a catalog-info.yaml from each repository. Write one for the service you templated — ownership, domain and component type.

TOPIC 03

GitOps with ArgoCD

Git as the single source of truth for what runs.

What you'll practice

Declare a GitOps Application — guided · intermediate

A command you'll meet

mkdir ~/gitops

Guided Task

Declare a GitOps Application

GitOps means the cluster syncs itself from Git. Write the ArgoCD Application manifest that tells the controller to watch a repo and apply everything in it.

TOPIC 04

Policy & Guardrails

Guardrails that make violations impossible, not forbidden.

What you'll practice

Write an Admission Policy — practice · intermediate

A command you'll meet

mkdir ~/policies

Practice Task

Write an Admission Policy

Platform teams enforce policy at admission time — the cluster simply rejects workloads that break the rules. Write a Kyverno-style policy banning privileged containers.
