phpMyAdmin as PHP-FPM container

Question

I've these two containers:

  nginx:
    image: nginx:1.17.4-alpine
    container_name: nginx
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - './certs:/etc/nginx/certs'
      - './site.conf:/etc/nginx/conf.d/site.conf'
  pma:
    image: phpmyadmin/phpmyadmin:4.9-fpm
    container_name: pma
    environment:
      - PMA_ARBITRARY=1
      - 'PMA_ABSOLUTE_URI=https://pma.local/'

In site.conf, how can I "pass" requests to PhpMyAdmin on port 9000? I've tried:

server {
    listen 443 ssl;
    server_name pma.local;
    ssl_certificate /etc/nginx/certs/pma.local.crt;
    ssl_certificate_key /etc/nginx/certs/pma.local.key;

    location / {
        proxy_pass https://pma.local:9000;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param SCRIPT_NAME $fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

But this is clearly not working...could you please point me in the right direction? Thanks.

What is the error you are getting, is it nginx error or the app itself not working or is it docker error? can help in pointing out the issue — ROOT, Jan 18 '20 at 19:13
You might want to ask this on [Server Fault](//serverfault.com) as this is more about configuring nginx — Machavity, Jan 18 '20 at 19:25

When using docker-compose it automatically creates a network for all containers so they can communicate with each other. Each container can be resolved using it's name in the docker-compose file, the following names are used in your file: nginx and pma.

This means pma should be used when searching for the fpm(fastcgi_pass):

 location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass pma:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param SCRIPT_NAME $fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
