The proposal is to add support of adding a new proxy_set_header entry to the nginx config using an annotation. For example I need to add proxy_set_header X-Request-Start "t=${msec}”; in order to report request queuing in New Relic. from:...
Kubernetes uses kube-proxy to expose Services and provide load balancing. The implementation is at the transport layer. When it comes to Internet applications, where a bu
实现此行为的一种方法是滥用金丝雀特性。对于您的backend-service，创建一个普通的Ingress，e. g的。
nginx.ingress.kubernetes.io/canary-by-header-pattern This rule is similar to canary-by-header-value. The only difference is that this annotation uses a regular expression, not a fixed value, to match the value of the request header. If this annotation and canary-by-header-value exist at the...
