Lately I’m playing with Docker and as exercise I tried to setup full installation of WordPress using docker.
The most simple is to use official wordpress repository. The problem was that wordpress container doesn’t support sending mails. The easiest way to provide such functionality is to install ssmtp. So I created a container for that purpose defragmentator/wordpress_ssmtp
Sources are published on my GitHub.
That container enables user to easy configure outgoing email account with environment variables. If someone prefer to use config file on volume (/etc/ssmtp/ssmtp.conf) it is also possible.

config.yml:

version: '3'

services:
   db:
     image: mysql:5.7
     volumes:
       - /home/docker/wordpress/db:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: mysql
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   wordpress:
     depends_on:
       - db
     volumes:
       - /home/docker/wordpress/html:/var/www/html
     image: defragmentator/wordpress_ssmtp:fpm
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
       SSMTP_ROOT: [email protected]
       SSMTP_MAILHUB: smtp.gmail.com:587
       SSMTP_USETLS:  'YES'
       SSMTP_USESTARTTLS:  'YES'
       SSMTP_FROMLINEOVERRIDE: 'YES'
       SSMTP_AUTHUSER: [email protected]
       SSMTP_AUTHPASS: password


   web:
        image: nginx:latest
        restart: always
        ports:
            - "80:80"
        volumes:
            - /home/docker/wordpress/log:/var/log/nginx
            - /home/docker/wordpress/html:/var/www/html
            - /home/docker/wordpress/nginx/default.conf:/etc/nginx/conf.d/default.conf

Having properly edited config.yml deployment can be done with command:

sudo docker stack deploy -c config.yml wordpresssite

My repository contains of two branches: apache and fpm. I prefere fpm with nginx, bacause it was much simpler to deploy with CloudFlare. To get real IPs of users I added some lines to default.conf:

set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 104.16.0.0/12;

set_real_ip_from 141.101.64.0/18;
set_real_ip_from 162.158.0.0/15;
set_real_ip_from 172.64.0.0/13;
