Question

为了在minikube中的k8s上运行php-fpm应用，我在这里缺少一些kubernetes ingress-nginx配置。

k8s配置文件：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /

在以前的docker开发环境的docker nginx映像上使用的工作配置文件（nginx在docker中是与php容器分开的容器）：

server {

    listen 443 default_server ssl;

    root   /opt/app/public;
    index  index.php;

    ...

    location / {
       try_files $uri $uri/ /index.php$is_args$args;
    }

    location /healthcheck {
        return 200 'ok';
        add_header Content-Type text/plain;
    }

    error_page 404 /index.php;

    location ~ ^/(index)\.php(/|$) {

        fastcgi_pass php:9000;
        fastcgi_index index.php;

        include fastcgi_params;
    }
}

在浏览器上访问minikube ip时出现502错误。

我已安装 ingress-nginx 并运行以下命令（如其installation guide中所述）

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml
$ minikube addons enable ingress
$ make dev-env

我假设我需要以某种方式将根（nginx conf）映射到/ opt / app / public，并以某种方式在ingress-nginx中配置fastcgi_pass，老实说，我仍然对所有的工作方式有些迷惑。

这可能是以下问题之一。您的进入似乎很好。

您是要在与php容器相同的pod中运行nginx容器吗？在同一容器中运行nginx之后，您必须将fastci_pass中的“ php”替换为“ 127.0.0.1”。
检查您的pod日志，如果您收到connection refused，则说明您的php容器有问题，它没有正确暴露端口。尝试对您的php pod进行port-forward ing操作，看看是否可以通过localhost访问5000。
我看到您在php：9000上有fastcgi_pass，应该是5000吗？
