Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop — Lesson 2: Functions, Containers, Registry, OKE, and Application Deployment

Learning Objectives

• Explain the purpose and operating context of OCI Functions applications, triggers, dependencies, and execution context.
• Apply container images, OCI Registry, scanning, tags, and lifecycle and OKE workloads, services, ingress, config maps, secrets, and scaling in a controlled environment.
• Validate outcomes and troubleshoot risks involving deployment validation, rollback, health probes, and environment promotion.

Detailed Topics

• OCI Functions applications, triggers, dependencies, and execution context
• container images, OCI Registry, scanning, tags, and lifecycle
• OKE workloads, services, ingress, config maps, secrets, and scaling
• deployment validation, rollback, health probes, and environment promotion

Instructor Demonstration

Demonstrate OCI Functions applications, triggers, dependencies, and execution context for an event-driven order application implemented and deployed through OCI developer services; capture the exact configuration, code, command, transaction, query, dashboard, model, schedule, or report evidence that proves the expected result.

Hands-On Exercise

Complete a controlled Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop exercise covering container images, OCI Registry, scanning, tags, and lifecycle and OKE workloads, services, ingress, config maps, secrets, and scaling; introduce an exception involving deployment validation, rollback, health probes, and environment promotion, diagnose it from evidence, apply the smallest reversible correction, and rerun acceptance checks.

1. Confirm scope, prerequisites, identities, dependencies, data, risks, and expected outcome.
2. Perform the course-specific configuration, development, administration, analysis, or business-process workflow.
3. Capture commands, settings, records, logs, screenshots, reports, metrics, or test results.
4. Compare the observed result with acceptance criteria and document corrective or preventive action.

Scenario Analysis

• Identify the technical or business decision and the stakeholders affected by it.
• Compare security, performance, reliability, compliance, cost, usability, and support trade-offs.
• Define rollback, recovery, communication, evidence, ownership, and escalation requirements.

Troubleshooting Guidance

Diagnose issues involving OCI Functions applications, triggers, dependencies, and execution context, container images, OCI Registry, scanning, tags, and lifecycle, OKE workloads, services, ingress, config maps, secrets, and scaling, deployment validation, rollback, health probes, and environment promotion without making an unverified production change. Separate symptoms from causes, gather time-correlated evidence, test a reversible hypothesis, validate the correction, and record recurrence controls.

Validation Checklist

• The requirement, environment, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by product-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, support actions, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply Functions, Containers, Registry, OKE, and Application Deployment in a realistic Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop scenario and defend the result with documented evidence.
