Question

我在AKS服务上有Nginx开源。一切都很好，但无法提供诸如index.html或favicon.ico之类的静态内容。

当我打开http：//时，默认情况下不提供index.html [我得到404]，如果尝试打开任何静态内容，我将得到404错误。

nginx配置是作为ConfigMap传递的，下面是有关提供静态内容的配置文件。

server {
listen 80;
server_name localhost;
root /opt/abc/html; #also tried root /opt/abc/html/

location / {
root /opt/abc/html; #also tried root /opt/abc/html/
index index.html;
try_files $uri $uri/ /index.html?$args;

...
...
..

proxy_pass http://tomcat;
}
}

设置： AKS上的Kubernetes Nginx开源[没有入口] configMaps挂载config.d 静态内容（/ opt / abc / html）通过kubernetes cp命令传递到了pod中。 [这行吗？]

下面是从ConfigMap挂载nginx.conf的示例

并确保您在更新ConfigMap之后kubectl rollout restart deployment echoserver。 Pod仅在创建时克隆ConfigMap。它不会同步或自动更新。
