在 Istio 中指定 TLS 流量时,对等方重置连接

问题描述 投票:0回答:1

我有一个分布式数据库(Consul),我想在 Kubernetes 上的 Istio 中运行它。对等点之间的通信使用 mTLS 进行加密和验证。我正在使用无头服务来允许对等点相互联系:

apiVersion: v1
kind: Service
metadata:
  name: cluster
  namespace: consul
spec:
  clusterIP: None
  publishNotReadyAddresses: true
  selector:
    app: consul
  ports:
  - name: tcp-server
    port: 8300
    targetPort: 8300
  - name: tcp-serflan
    protocol: TCP
    port: 8301
    targetPort: tcp-serflan
  - name: udp-serflan
    protocol: UDP
    port: 8301
    targetPort: udp-serflan

但是,当我在无头服务

tcp-server
上命名
tls-server
端口时,我看到了大量连接重置错误:

Istio/Envoy 如何处理可能导致此问题的 TLS 流量?流量是 TLS 流量(我正在做this),因此似乎有必要假装流量是 TCP。

  • 领事版本:
    1.6.2
  • Istio 版本:
    1.4.4
istio consul envoyproxy

在尝试在使用相互 TLS 保护的 istio 网格中公开 HTTPS 端口时,我遇到了同样的问题

我最终在我的服务上禁用了 TLS,因为 istio 无论如何都会加密流量
