How to proxy php-fpm program in Docker with Nginx installed outside of Docker-CodePudding

Assume I have a php-fpm program inside a Docker container (for example bitnami/bitnami-docker-php-fpm), and I don't want to use a Nginx container, how can I proxy it with Nginx installed outside of Docker?

CodePudding user response：

For example, if you are running the Nginx ingress controller or one specific container of Nginx

POD

apiVersion: v1
kind: Pod
metadata:
  name: example-app
labels:
  app: example-app
spec:
  containers:
  - name: example-app
    image: example-app:1.0
    ports:
    - containerPort: 9000
      name: fastcgi

Serivce

apiVersion: v1
kind: Service
metadata:
  name: example-service
spec:
  selector:
    app: example-app
  ports:
  - port: 9000
    targetPort: 9000
    name: fastcgi

ingress

apiVersion: v1
kind: ConfigMap
metadata:
  name: example-cm
data:
  SCRIPT_FILENAME: "/example/index.php"

If your Nginx running outside of docker you can use the host machine IP

server {
    listen  80;

    server_name localhost;
    root /var/www/test;

    error_log /var/log/nginx/localhost.error.log;
    access_log /var/log/nginx/localhost.access.log;

    location / {
        # try to serve file directly, fallback to app.php
        try_files $uri /index.php$is_args$args;
    }

    location ~ ^/. \.php(/|$) {
        fastcgi_pass 192.168.59.103:9000;
        fastcgi_split_path_info ^(. \.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param HTTPS off;
    }
}
