Advanced DevOps – Puppet, Terraform and Kubernetes — Lesson 4: Deploying Kubernetes Workloads and Operating the Full Automation Chain

Technical Scope

• Kubernetes manifests, Helm, configuration, and secrets
• Namespaces, policies, services, ingress, and scaling
• Pipeline orchestration across all three tools
• Observability, upgrades, rollback, and incident evidence

Instructor Demonstration

Deploy an application after infrastructure and node configuration checks pass.

Applied Workshop

Add a gated upgrade path with health checks and rollback conditions.

1. Translate the scenario into configuration, access, state, pipeline, or module decisions.
2. Implement the change in a controlled workspace or repository.
3. Capture the plan, logs, outputs, policy results, and post-change checks.
4. Explain one safer or more maintainable alternative and its trade-off.

Validation Standard

Application rollout depends on verified infrastructure and node readiness, with traceable evidence.

• The intended target, identity, environment, and state boundary are confirmed.
• The plan or execution evidence contains no unexplained destructive action.
• Security, reliability, maintainability, and operational ownership are reviewed.
• The final result can be reproduced from version-controlled inputs.

Failure Analysis

Diagnose failed pods, configuration mismatch, network exposure, upgrade regression, and cross-layer drift.

Learners isolate the smallest verified cause, correct it, rerun the relevant validation step, and record the preventive action in the course improvement log.
