Skill UI

An expert guide for designing, implementing, and optimizing large-scale, secure, and highly available cloud-native infrastructure using Kubernetes. Covers advanced topics including GitOps workflows (ArgoCD/Flux), service mesh architecture (Istio), multi-cluster management, Policy as Code (OPA), and infrastructure automation with Terraform. Ideal for platform engineers building enterprise-grade container orchestration solutions.

OPA Gatekeeper is a powerful Kubernetes admission controller that enforces policies using Rego rules. It utilizes ConstraintTemplates and Constraints to validate, mutate, or deny API requests at the cluster admission stage. This tool is essential for implementing policy-as-code practices, ensuring that Kubernetes deployments adhere to organizational security standards, compliance requirements, and best practices, such as mandating labels or blocking privileged containers.

KubeEye is a comprehensive cluster inspection tool designed for Kubernetes environments, particularly within KubeSphere. It systematically detects issues across workloads, nodes, and configurations by integrating multiple policy engines, including OPA/Rego, PromQL, file integrity checks, kernel parameter validation, and systemd health checks. Users can define custom inspection rules (InspectRule), schedule checks (InspectPlan), and retrieve detailed reports (InspectResult) to ensure cluster compliance and stability.
