Kubernetes / Advanced: extensibility, resilience, and lifecycle

Kubernetes β€” Advanced: extensibility, resilience, and lifecycle

Reason about controllers, disruption, tenants, scaling, upgrades, and incident ownership under explicit assumptions.

6 lessons Β· No account required

What you will learn

  • Design repeat-safe reconciliation and recovery ownership.
  • Evaluate security, availability, and capacity as layered contracts.
  • Plan compatibility and incident decisions with verifiable evidence.

  1. Controllers, custom resources, and Operators

    Design convergent control loops with explicit schema, ownership, status, and cleanup rather than treating an Operator as automatic application expertise.

    Start learning

  2. Availability and disruption budgets

    Combine replica placement, voluntary disruption controls, termination, and application recovery into a realistic availability contract.

    Start learning

  3. Workload security and multi-tenancy

    Combine authorization, admission, runtime restrictions, network controls, and operational ownership for an explicit tenant threat model.

    Start learning

  4. Autoscaling and capacity limits

    Relate workload metrics, replica decisions, scheduling, and dependency budgets without expecting autoscaling to create immediate unlimited capacity.

    Start learning

  5. Cluster upgrades and API lifecycle

    Plan version, API, plugin, and data compatibility together without treating an upgrade or rollback as one universal command.

    Start learning

  6. GitOps ownership and incident diagnosis

    Coordinate declarative automation and human response while preserving evidence, scoped authority, and application recovery.
