Kubernetes β€” Basic: objects and execution boundaries

Understand architecture, identity, Pods, discovery, configuration, and storage as separate operational contracts.

What you will learn

  • Trace intent from API acceptance to useful workload behavior.
  • Read selectors, scopes, discovery, credential, and data lifecycles.
  • Distinguish platform mechanisms from application guarantees.

  1. Architecture and declarative reconciliation

    Trace desired state through API storage, controllers, scheduling, and node execution without mistaking acceptance for a working service.

    Start learning

  2. Objects, labels, and namespaces

    Read object identity and desired-state fields, use selectors deliberately, and understand the limits of namespace separation.

    Start learning

  3. Pods and workload controllers

    Choose a workload model from process lifetime, identity, completion, and replacement requirements rather than treating every task as a bare Pod.

    Start learning

  4. Services, endpoint selection, and DNS

    Trace service discovery from a DNS name through a Service and ready endpoints to the intended application port.

    Start learning

  5. Configuration, Secrets, and workload identity

    Separate nonsecret settings, credential references, and workload identity while understanding how consumers receive updates.

  6. Storage claims and data lifecycle

    Distinguish ephemeral data, persistent claims, storage provisioning, and recovery guarantees before choosing a workload storage contract.
