# ClusterIssuer 配置示例
kubectl apply -f - <<EOF

    server: https://acme-v02.api.letsencrypt.org/directory
    email: admin@example.com
    privateKeySecretRef:
      name: letsencrypt-alidns-key
    solvers:
      - dns01:
          webhook:
            groupName: acme.alidns.com
            solverName: alidns
