NoServerCertificateVerificationDestinationLevel
消息名称 | NoServerCertificateVerificationDestinationLevel |
消息代码 | IST0128 |
描述 | No caCertificates are set in DestinationRule, this results in no verification of presented server certificate. |
等级 | Error |
如果流量策略需要 caCertificates
,但是在目标规则(Destination Rule)中没有相关信息,会出现该问题。
示例
当您的集群中包含以下目标规则时(Destination Rule):
apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
name: db-tls
spec:
host: mydbserver.prod.svc.cluster.local
trafficPolicy:
tls:
mode: SIMPLE
clientCertificate: /etc/certs/myclientcert.pem
privateKey: /etc/certs/client_private_key.pem
# caCertificates not set
您将会收到以下信息:
Error [IST0128] (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
在这个示例中,目标规则(Destination Rule)db-tls
被明确为 TLS,但是没有设置 CA 文件信息。
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
