我已经在GKE群集上部署了2个istio启用的服务。
istio的版本为1.1.5，GKE位于v1.15.9-gke.24
istio已与global.mtls.enabled=true一起安装
serviceA能够正确通信
serviceB显然存在与TLS相关的问题。
我启动了一个非istio启用的部署，仅用于测试，然后执行到此curl这两个服务端点的测试包中。
/ # curl -v serviceA

进入有问题的服务的envoy代理并打开跟踪级别日志记录后，我看到此错误

两个容器的特使边车，在调试其证书时显示类似的信息。
我通过在两个istio容器中执行，cd-/etc/certs/..data并运行
openssl x509 -in root-cert.pem -noout -text
两个root-cert.pem是相同的！
由于这2个istio代理在证书方面具有完全相同的tls配置，为什么在serviceB上出现这种神秘的SSL错误？
FWIW serviceB与未启用istio的postgres服务进行通信。
那是造成问题的原因吗？
curling serviceB的容器容器本身会返回健康的响应。
