This skill provides expert guidance for Azure Redhat Openshift. Covers troubleshooting, best practices, decision making, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.
Manages Kubernetes and OpenShift clusters: operations (upgrades, backups, scaling), troubleshooting (pods, networking, storage), manifests (Deployments, Services, RBAC), security (audits, scans), GitOps (ArgoCD, Flux, Helm).
Plans, creates, and configures production-ready Azure Kubernetes Service (AKS) clusters including Day-0 checklists, SKU selection, networking, security, and autoscaling.
Provides expert guidance on Kubernetes, OpenShift, and OLM: debugging resources like pods/deployments, operator development/troubleshooting, manifest/CRD reviews, and cluster investigations.
