One of the things I ran into that has been painful was configuring a listener to use SSL/TLS. Envoy proxy can be configured to do the SSL termination and require a client certificate by setting the Downstream TLS Context on the listener and setting require_client_certificate to true. For context, here's a high-level diagram of Zuul 2's architecture: The Netty handlers on the front and back of the filters are mainly responsible for handling the network protocol, web server, connection management and proxying work. type Cluster_CommonLbConfig struct { HealthyPanicThreshold *_type. There is considerable interest within the Kafka community in the possibility of leveraging more Istio features via out-of-the-box tracing, and mTLS through protocol filters, though these features have different requirements as reflected in Envoy, Istio. Support is sufficient for Envoy to perform standard edge proxy duties for modern web services as well as to initiate connections with external services that have advanced TLS requirements (TLS1. 这用于上游主机提供给客户端的tls证书。 private_key_file (optional, string) 与证书文件链相对应的私钥。 ca_cert_file (optional, string) 包含证书颁发机构的证书文件,用于验证服务器提供的证书。.
