当我在 Kubernetes 集群中运行客户端时，与 redis 的连接正常，但在 istio 网格中运行时出现“管道损坏”错误

我相信它需要给更多的连接时间但不确定，在此先感谢。
最佳答案
好吧，Istio 阻止了与 redis 的连接，因此创建了一个服务条目并且它起作用了! https://istio.io/blog/2018/egress-tcp/#mesh-external-service-entry-for-an-external-mysql-instance
关于在 istio 网格中运行时出现 Redis 断管错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52305324/
