Getting started with OpenShift for Developers (featuring odo)

There are differences between Red Hat OpenShift and "vanilla Kubernetes," and Red Hat OpenShift helps developers build, instrument, and manage containerized solutions that can be run more securely on any infrastructure.

In this breakout session, we'll:

Highlight a few unique developer-focused features that have been included in Red Hat's Cloud Native Computing Foundation-certified (CNCF-certified) distribution of Kubernetes.
See live demos showing how to quickly build, test, and iterate on Java-based solutions via IDE or via command-line.
Show you how to iterate at top speed using the odo command line tool while taking advantage of deep platform insights made available through the newly redesigned "developer perspective" web interface.

Distributions by Red Hat • RHEL 8 for Enterprise Productivity • RHEL CoreOS for Container Hosts • Fedora for reliable access to early upstream bits • Universal Base Images for Containerized Workloads • Fedora IoT for Edge Enablement ➜ OpenShift is a complete Cloud Platform built around Kubernetes

13. Developer Productivity in Scope A distributable cloud platform - consistently deliverable to any hardware environment, including bare metal Kubernetes OpenShift Developer Productivity Out of scope Developer Perspective (app-centric topology view, live terminals, logs, and stats), Routes (easy hostname records), Developer Catalog (Operator-backed, Admin configurable) Inner Loop Out of scope CodeReady Workspaces (hosted IDE w/ VScode plugin support), odo (“cf push” style code promotion between commits) Builds, Pipelines Out of scope Tekton pipelines, Buildah (runs builds on cluster, producing container images that do not require root privs) Container Registry Out of scope Quay w/ Clair for static image analysis (on-cluster) Logging Out of scope Prometheus (on-cluster, Developer Perspective dashboard includes PromQL and live data) Service Mesh Out of scope Istio 1.4.6, Kiali 1.12.7, Jaeger 1.17.1 (on-cluster) Serverless Out of scope Knative (on-cluster, Developer Perspective dashboard integration) Advanced Workloads & Marketplace CRDs (v1.12+ recommended) Dashboard support for CRDs, Disk storage (volumes and claims), Operator Marketplace (on-cluster), Helm3, KubeVirt (VMs), GPUs

24. kubectl oc odo Community standard command line tool for interacting with Kubernetes API resources ✅ Support for kubectl plugins and CustomResourceDefinitions for extended functionality ✅ ✅ A drop-in replacement for kubectl that includes support for OpenShift-specific resources types ✅ Credentials management and cluster login support via oc login ✅ ✅ Enhanced support for Kubernetes namespaces ✅ ✅ Automatically sync code changes into a cluster: oc rsync, odo watch ✅ ✅ Ability to preview code changes on the cluster: odo push (comparable to cf push) ✅ Enhanced support for application components and label management. Quickly adopt best-practices while you work ✅ Command Line Options Choose the right tool for the job
25. Odo usage examples
26. odo create <component_type> [component_name] [--local] [local_path] Command Syntax: Use local files and artifacts to preview changes while odo provides enhanced support for application-component labels and context management odo create nodejs frontend --local ./frontend odo create java:11 backend --binary ./target/myapp.war Examples: Application Components
27. Iterative development with odo • Decouple pushes from commits to increase commit accuracy • Push local sources to initiate hosted builds and deployments • Push local binary build artifacts into remote containers odo push
28. Inner loop development with odo • Watch local sources and/or binary artifacts for updates, then replicate changes into a hosted container • Synchronize HTML, CSS, and interpreted language sources to achieve tighter loops with production-grade instrumentation • Minimal feedback latency odo watch
29. Results in Perspective ✅ via command-line ✅ via IDE integrations ✅ via the Developer Perspective Iterative feedback available:
