为什么需要动态更新呢?因为在一个kubernetes集群里service的endpoints可能会频率变动,如果都静态写进nginx.conf配置文件就意味着每次endpoints变动都要nginx -s reload 重新加载配置文件,在高并发下可能会导致某些请求时延变长,所以就需要借助lua-nginx-module使用lua来动态更新upstream上游节点。
1.ingress controller通过和kubernetes api交互,动态的去感知集群中ingress规则变化, 2.然后读取它,按照自定义的规则,规则就是写明了哪个域名对应哪个service,生成一段nginx配置, 3.再写到nginx-ingress-control的pod里,这个Ingress controller的pod里运行着一个Nginx服务,控制器会把生成的nginx配置写入/etc/nginx.conf...

Nginx Ingress Controller通过API Server获取Ingress资源的变化,动态地生成Load Balancer(例如Nginx)所需的配置文件(例如nginx.conf),然后重新加载Load Balancer(例如执行nginx -s reload重新加载Nginx)来生成新的路由转发规则。 诊断流程 按照以下步骤,检查是否是由于Ingress所导致的问题,确保Ingress Controller的配置正确。
Nginx Ingress 注解使用在 Ingress 资源实例中,用以设置当前 Ingress 资源实例中 Nginx 虚拟主机的相关配置,对应配置的是 Nginx 当前虚拟主机的 server 指令域内容。在与 Nginx Ingress 配置映射具有相同功能配置时,将按照所在指令域层级遵循 Nginx 配置规则覆盖。
controllers that can do this job, it’s important to choose the right one for the type of traffic and load coming into your Kubernetes cluster. In this post, we will discuss how to use an NGINX ingress controller on Amazon EKS, and how to front-face it with a Network Load Balancer (...
