admissionWebhook配置
Nginx Ingress Controller支持admissionWebhook配置，通过设置controller.admissionWebhook参数，可以对Ingress对象进行有效性校验，避免因配置错误导致ingress-controller不断重新加载资源，导致业务中断。 
使用admissionWebhook特性时，APIServer需要开启webhook相关配置，必须包含MutatingAdmissionWebhook与ValidatingAdmissionWebhook特性开关为 --admission-control=MutatingAdmissionWebhook,ValidatingAdmissionWebhook 如未开启，需要提交工单申请开启。 开启admissionWebhook特性后，如需卸载重装Nginx Ingress Controller，会有Secret残留，需要手动清理。开启admissionWebhook的value.yaml配置文件如下： controller: image: repository: swr.cn-east-3.myhuaweicloud.com/hwofficial/nginx-ingress #controller镜像地址，请根据集群所在区域进行替换 registry: "" image: "" tag: "v1.5.1" #controller版本 digest: "" ingressClassResource: name: ccedemo #同一个集群中不同套Ingress Controller名称必须唯一，且不能设置为nginx和cce controllerValue: "k8s.io/ingress-nginx-demo" #同一个集群中不同套Ingress Controller的监听标识必须唯一，且不能设置为k8s.io/ingress-nginx ingressClass: ccedemo #同一个集群中不同套Ingress Controller名称必须唯一，且不能设置为nginx和cce service: annotations: kubernetes.io/elb.id: 5083f225-9bf8-48fa-9c8b-67bd9693c4c0 #ELB ID kubernetes.io/elb.class: performance #仅独享型ELB需要添加此注解 config: keep-alive-requests: 100 extraVolumeMounts: # 挂载节点上的/etc/localtime文件，进行时区同步 - name: localtime mountPath: /etc/localtime readOnly: true extraVolumes: - name: localtime type: Hostpath hostPath: path: /etc/localtime admissionWebhooks: annotations: {} enabled: true extraEnvs: [] failurePolicy: Fail port: 8443 certificate: "/usr/local/certificates/cert" key: "/usr/local/certificates/key" namespaceSelector: {} objectSelector: {} labels: {} existingPsp: "" networkPolicyEnabled: false service: annotations: {} externalIPs: [] loadBalancerSourceRanges: [] servicePort: 443 type: ClusterIP createSecretJob: resources: #注释{} limits: cpu: 20m memory: 40Mi requests: cpu: 10m memory: 20Mi patchWebhookJob: resources: {} patch: enabled: true image: registry: registry.k8s.io #registry.k8s.io为webhook官网镜像仓库，需要替换成自己镜像所在仓库地址 image: ingress-nginx/kube-webhook-certgen #webhook镜像 tag: v1.1.1 digest: "" pullPolicy: IfNotPresent priorityClassName: "" podAnnotations: {} nodeSelector: kubernetes.io/os: linux tolerations: [] labels: {} securityContext: runAsNonRoot: true runAsUser: 2000 fsGroup: 2000 resources: # 设定controller的资源限制，可根据需求自定义 requests: cpu: 200m memory: 200Mi defaultBackend: # 设置defaultBackend enabled: true image: repository: swr.cn-east-3.myhuaweicloud.com/hwofficial/defaultbackend #defaultBackend镜像地址，请根据集群所在区域进行替换 registry: "" image: "" tag: "1.5" digest: ""验证Ingress配置错误annotation场景下，admissionWebhook是否会进行校验。 例如，为Ingress配置以下错误的annotation： ... annotations: nginx.ingress.kubernetes.io/auth-tls-pass-certificate-to-upstream: "false" nginx.ingress.kubernetes.io/auth-tls-verify-client: optional nginx.ingress.kubernetes.io/auth-tls-verify-depth: "1" ...创建此Ingress服务，将会出现以下拦截信息：
