[Question] Will there be a php-fpm-nginx image?

[bkuhl]

Currently there's an fpm variant that includes apache. I'd really like to see an nginx variant of this as well. Running nginx/fpm in separate containers leads to nginx dns caching issues when the fpm container is redeployed.

Are there plans to add an nginx variant and/or a reason why we shouldn't?

[tianon]

There are no plans to add an nginx variant, since we'd then have to start both NGINX and FPM in the same container, and manage/monitor both their lifecycles directly (since NGINX does not, to my knowledge, have a way to directly invoke and manage the FPM processes in a simple well-supported way).

The Apache variant does NOT use FPM -- it uses mod_php. 👍

This setup has proven to be simple and reliable for me:

supervisord.conf

[supervisord]
nodaemon = true
logfile = /dev/null
logfile_maxbytes = 0

[program:php-fpm]
command = /usr/local/sbin/php-fpm
stdout_logfile = /dev/stdout
stdout_logfile_maxbytes = 0
stderr_logfile = /dev/stderr
stderr_logfile_maxbytes = 0

[program:nginx]
command = /usr/sbin/nginx -g "daemon off;"
stdout_logfile = /dev/stdout
stdout_logfile_maxbytes = 0
stderr_logfile = /dev/stderr
stderr_logfile_maxbytes = 0

nginx.conf

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
    worker_connections 1024;
}

http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';

    access_log /var/log/nginx/access.log main;

    server {
        listen 80;
        server_name _;
        root /var/www/html;

        index index.php index.html;

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

        location ~ \.php$ {
            try_files $uri =404;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_pass localhost:9000;
        }
    }
}

Actually, this past weekend I started using https://github.com/bkuhl/fpm-nginx/ in production. It's the same concept, but using S6 Overlay instead of Supervisor.
