作为cert-manager的核心扩展组件,本镜像的主要用途包括:
本镜像适用于以下场景:
通常需通过Kubernetes资源清单部署,示例Deployment配置片段:
yamlapiVersion: apps/v1 kind: Deployment metadata: name: cert-manager-webhook namespace: cert-manager spec: replicas: 1 selector: matchLabels: app: cert-manager-webhook template: metadata: labels: app: cert-manager-webhook spec: containers: - name: webhook image: [本镜像地址] ports: - containerPort: 443 volumeMounts: - name: webhook-tls mountPath: /tls readOnly: true args: - --tls-cert-file=/tls/tls.crt - --tls-private-key-file=/tls/tls.key volumes: - name: webhook-tls secret: secretName: cert-manager-webhook-tls
部署时需重点配置以下内容:
yamlapiVersion: v1 kind: Service metadata: name: cert-manager-webhook namespace: cert-manager spec: selector: app: cert-manager-webhook ports: - port: 443 targetPort: 443
yamlapiVersion: cert-manager.io/v1 kind: ClusterIssuer metadata: name: custom-ca-issuer spec: webhook: groupName: example.com solver: webhook: config: apiVersion: webhook.example.com/v1alpha1 kind: WebhookConfiguration url: [***]
