对我来说，它的外观，就像你的请求没有达到Nginx容器本身。所以尝试下面提到的选项。
由于Nginx入口作为守护程序集运行，因此Nginx容器端口80和443Map到主机的80和443端口。因此您可以使用http：//{node-IP}连接到Nginx容器。您可以使用3个节点中的任何一个node-IP。一旦请求到达Nginx容器，则在检查您创建的资源规则后，它将被路由到后端容器。因此您可以使用http//{node-ip}/jenkins连接到jenkins容器。
要使用curl客户端进行测试，可以使用主机名欺骗。curl -H“主机：jenkins.company.com“http：//{主机IP}/Jenkins
