VMware vSphere with Tanzu: Deploy and Manage [V7] — Lesson 3: Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment

Learning Objectives

• Break down the prerequisites, components, roles, and decision points involved in Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment.
• Complete a controlled activity for Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment and capture cluster deployment trace and application connectivity test.
• Challenge the result with image pulls failing because the namespace cannot reach the registry endpoint, then justify the corrective action.

Detailed Topics

• Tanzu Kubernetes clusters
• Manifests
• Kubectl access
• Services
• Ingress
• Registries
• Persistent volumes
• Secrets
• Scaling
• Updates
• And workload deployment
• Decision ownership, prerequisites, and acceptance evidence for Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The demonstration traces Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment from requirement through execution and review. Learners see where evidence should be collected, how cluster deployment trace and application connectivity test supports validation, and which warning signs require investigation.

Hands-On Exercise

Work through a role-based scenario involving Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment. Validate the expected path, test “image pulls failing because the namespace cannot reach the registry endpoint,” choose the safest corrective action, and capture the reasoning and outcome in cluster deployment trace and application connectivity test.

1. Record the starting state, assumptions, identities, topology, and expected outcome.
2. Execute the planned workflow and collect evidence at each material checkpoint.
3. Test one valid path, one boundary condition, and the stated failure scenario.
4. Document the correction, retest result, rollback option, and follow-up owner.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how cluster deployment trace and application connectivity test should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

When Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment produces an unexpected result, reproduce the issue with the same scope, identity, workload, and time context. Inspect cluster deployment trace and application connectivity test, test whether “image pulls failing because the namespace cannot reach the registry endpoint” explains the evidence, apply the smallest reversible correction, and retest an unaffected path for regression.

Validation Checklist

• Configuration and source state used for Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment are versioned or otherwise traceable.
• Cluster deployment trace and application connectivity test shows both baseline and accepted result.
• Security, performance, dependency, and resilience side effects are considered where relevant.
• Recovery steps and handover notes are usable by an operations practitioner.

Lesson Outcome

Learners can apply Tanzu Kubernetes clusters, manifests, kubectl access, services, ingress, registries, persistent volumes, secrets, scaling, updates, and workload deployment, explain the decisions made, and defend the result with cluster deployment trace and application connectivity test.
