NoServerCertificateVerificationPortLevel
消息名称 | NoServerCertificateVerificationPortLevel |
消息代码 | IST0129 |
描述 | No caCertificates are set in DestinationRule, this results in no verification of presented server certificate for traffic to a given port. |
等级 | Warning |
当流量策略需要 caCertificates
时,但目标规则(Destination Rule)中没有设置相关信息时会出现该错误。
示例
当您的集群中具有以下目标规则(Destination Rule)时:
apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
name: db-tls
spec:
host: mydbserver.prod.svc.cluster.local
trafficPolicy:
portLevelSettings:
- port:
number: 443
tls:
mode: SIMPLE
clientCertificate: /etc/certs/myclientcert.pem
privateKey: /etc/certs/client_private_key.pem
sni: my-nginx.mesh-external.svc.cluster.local
# caCertificates not set
您将会收到以下信息:
Error [IST0129] (DestinationRule db-tls.default) DestinationRule default/db-tls in namespace default has TLS mode set to SIMPLE but no caCertificates are set to validate server identity for host: mydbserver.prod.svc.cluster.local at port number:443
在这个示例中,目标规则 db-tls
被指定为 TLS ,但是没有提供相关 CA 证书。
解决方案
- 提供 CA 证书的文件名
- 修改流量策略为不需要证书的类型
