port: 80 protocol: TCP targetPort: 8080 selector: app: my-nginx 总结 本文主要讲了 kubernetes 中 service 的原理、实现以及使用方式,service 目前主要有 5 种服务暴露方式,service 的容器发现是通过 endpoints 来实现的,其服务发现主要是通过 DNS 实现的,其负载均衡以及流量转发是通过 kube-proxy 实现的。在...

However, the exact port is specified when the endpoint is created. Protocol Layers Service Broker takes a layered approach to communication. Each layer builds on the underlying layer to help ensure reliable delivery. This approach allows an application to operate without knowledge of the location of...
