CKA题目分享-第七篇-Gateway API与Pod Admission

运维栈记2025-12-16 8:32

Gateway API 是 Kubernetes 网络 SIG（Special Interest Group）孵化的一个项目，旨在提供一个更强大、更灵活、更具表现力的标准 API，用于管理集群的南北向（Ingress）和东西向（Service Mesh）流量。它被设计为 Ingress API 的继承者和替代方案，解决了 Ingress API 在复杂场景下的一些痛点。

题目说Controller已经安装，不用配置"GatewayClass"对象。先配置"Gateway"

复制代码

apiVersion: gateway.networking.k8s.io/v1
kind: Gateway
metadata:
  name: web-gateway
  namespace: default
spec:
  gatewayClassName: example-gw-class
  listeners:
    - name: http
      protocol: HTTP
      port: 80
      hostname: "web.example.com"
      allowedRoutes:
        namespaces:
          from: Same

接着配置"HTTPRoute"，

复制代码

apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
  name: web-route
  namespace: default
spec:
  parentRefs:
    - name: web-gateway
      sectionName: http
  hostnames:
    - "web.example.com"
  rules:
    - matches:
        - path:
            type: PathPrefix
            value: /
      backendRefs:
        - name: web-service
          port: 80

配置"LimitRange"，

复制代码

apiVersion: v1
kind: LimitRange
metadata:
  name: pod-resource-limits
  namespace: limit-test
spec:
  limits:
    - type: Container
      default:
        cpu: 200m
        memory: 100Mi
      defaultRequest:
        cpu: 100m
        memory: 50Mi
      max:
        memory: 500Mi
