最近,我已经将我的PHP网站从基本VM迁移到了Google Cloud上具有NGINX入口的Kubernetes。我注意到一个奇怪的问题,偶尔会返回502错误(来自openresty / 1.15.8.2)。对于以前使用过该应用程序并通过清除网站的所有缓存和cookie来解决该问题的人来说,这似乎尤其如此。网站本身完全没有改变。

最奇怪的是,它仅偶尔发生(每天从日志中几次),因此yml文件之间的引用没有问题。

ingress.yml:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: example-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/ssl-redirect: "true"
    cert-manager.io/acme-challenge-type: http01
    cert-manager.io/cluster-issuer: letsencrypt

spec:
  rules:
    - host: "example.app"
      http:
        paths:
        - path: /
          backend:
            serviceName: example-service
            servicePort: 80
  tls:
    - hosts:
        - "example.app"
      secretName: example.app-tls

configmap.yml:

kind: ConfigMap
apiVersion: v1
metadata:
  name: nginx-config
data:
  nginx.conf: |
    events {
    }

    http {
      server {
        listen 80;
        listen [::]:80;

        root /app/public;
        index index.php index.html index.htm;
        server_name example.app;

        location / {
          try_files $uri $uri/ /index.php?$query_string;
        }

        location ~ \.css {
          add_header Content-Type text/css;
          try_files $uri $uri/ /index.php?$query_string;
        }

        location ~ \.php$ {
          include fastcgi_params;
          fastcgi_param REQUEST_METHOD $request_method;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
          fastcgi_pass 127.0.0.1:9000;
        }

        proxy_connect_timeout 180s;
        proxy_send_timeout 180s;
        proxy_read_timeout 180s;
        send_timeout 180s;

        fastcgi_read_timeout 180s;
      }
    }

如果认为相关,我可以提供更多yml文件。
