Containerization & OCIR: Building and Managing Docker ImagesHands-on workshop covering Dockerfile best practices, multi-stage builds, image optimization, tagging strategies, and pushing/pulling images to Oracle Cloud Infrastructure Registry (OCIR). Lab: containerize a sample microservice and publish two versions to OCIR.2. Deploying Applications on OKE: Clusters, Node Pools & kubectlCreate and configure OKE clusters and node pools, generate kubeconfig, deploy manifests (Deployments, Services, Ingress), and use kubectl to manage rollouts and troubleshooting. Lab: deploy a two-service app behind an ingress controller and perform a controlled rollback.3. Traffic Control & Security with OCI Service MeshUnderstand Istio/Service Mesh concepts as implemented by OCI Service Mesh: virtual services, routing rules, canary releases, mutual TLS, policy enforcement and observability integration. Lab: implement a 10% canary, enable mTLS, and use mesh telemetry to trace requests.4. Serverless Development: Oracle Functions & API GatewayBuild, test and deploy serverless functions (Fn + OCI Functions), package dependencies, and wire functions to API Gateway endpoints and OCI Events. Lab: implement a REST endpoint backed by a function that persists data to a serverless datastore or object storage.5. Eventing and Messaging: OCI Streaming & OCI Queue PatternsLearn when to use Streaming vs Queue, working with partitions, retention, producers/consumers, SDK examples, and common patterns (pub/sub, fan-out, event sourcing). Lab: implement a producer that streams user events and a consumer that processes and stores results.6. Secrets & Access Management with OCI Vault and IAMSecure application secrets at runtime using OCI Vault (keys and secrets), integrate Vault access with functions and Kubernetes pods, and author least-privilege IAM policies. Lab: store API keys in Vault and access them from a function and an OKE pod (without hard-coding).7. Testing & Resilience: Unit, Integration, Contract and Chaos TestsBest practices for test pyramids in cloud-native apps: unit tests, integration tests, consumer-provider contract tests, and simple chaos tests (latency/error injection). Lab: add unit + integration tests to a microservice and run them in CI (sample pipeline).8. Observability: Monitoring, Logging, Tracing, Alerts & DashboardsInstrument apps with structured logging and distributed tracing; create metric queries, alarms, log groups and dashboard visualizations in OCI Monitoring and Logging. Lab: create an alert that fires on elevated 5xx rate and drill into traces to find the root cause.Prerequisites (short checklist)Basic programming in Python/Java/Node.js/Go; comfort with a CLI; Git basics; Docker basics; OCI account with Cloud Shell. (Full checklist and install checks included in pre-course materials.)
