转发端口时出现以下错误。谁能帮忙?
mjafary$ sudo kubectl port-forward sa-frontend 88:82
Forwarding from 127.0.0.1:88 -> 82

错误日志:

这里是吊舱的描述。我的期望是,当我在浏览器中命中localhost:88时,请求应转发到jafary / sentiment-analysis-frontend容器,并且应加载应用程序页面

拒绝连接的原因是,没有进程在端口82上进行监听。用于创建nginx映像的dockerfile公开了端口80,在您的pod规范中,您还公开了端口82。但是,nginx配置为监听在端口80上。
这意味着您的Pod有两个公开的端口:80和82。但是,nginx应用程序正在主动侦听端口80,因此仅对端口80的请求有效。
要使用端口82进行设置,您需要更改nginx配置文件,以便它监听端口82而不是端口80。您可以通过使用镜像中内置的更改创建自己的Docker镜像来执行此操作,或者您可以使用configMap将默认的配置文件替换为所需的设置]
