Problem

Non-production environments often run continuously even when nobody is using them. The challenge is not simply switching infrastructure off: dependencies must stop in a safe order and return with their previous state intact.

Architecture

Engineering decisions

• Suspend reconciliation before scaling application workloads.
• Persist previous replica counts rather than assuming defaults.
• Make stop/start actions idempotent and retry-safe.
• Expose manual status, start and stop operations for recovery.
• Treat infrastructure dependencies explicitly instead of relying on timing delays.

Selected code

def scale_workload(apps, namespace, name, replicas):
    body = {"spec": {"replicas": replicas}}

    return apps.patch_namespaced_deployment_scale(
        name=name,
        namespace=namespace,
        body=body,
    )

Keep snippets short. The surrounding explanation should communicate why the code exists and which failure mode it addresses.
