PrestaShop, Docker, SSL, Nginx Reverse Proxy

This is a common problem for Prestashop as viewed on the https://github.com/PrestaShop/docker and Prestashop forums. Here’s some configurations I found necessary to handle this. I was able to get it working. First off, there are a few files you need to keep in mind: The DB has two tables: ps_shop_url, ps_ssl_enabled, which must be edited manually. The nginx.conf must have the right settings (they can be the same as a wordpress reverse proxy, so start there). And it was necessary to set $_SERVER[‘HTTPS’] = ‘on’; in the prestashop_root/config/ folder under one of the defines. I used defines_custom.inc.php. I understand this is not best practice, but I got it to work. Interested users should research where it’s best to put custom edits for Prestashop. Here’s quickly some more notes:

nginx.conf:
# shopping site redirect
server {
#server tokens hides the nginx identifying itself
server_tokens off;
server_name shop.mysite.com;
listen 80;

location ^~ /.well-known {
alias /var/www/html/.well-known/;
#autoindex on;
}
location / {
##** nginx redirect ALL http requests to https ** ##
return 301 https://$server_name$request_uri;
#from gist mentioned below
#rewrite ^ https://$host$request_uri? permanent;}
}server {
#server tokens hides the nginx identifying itself
server_tokens off;
server_name shop.mysite.com;
#listen 80;
listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/mysite.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/mysite.com/privkey.pem;location / {
proxy_redirect off;
proxy_pass http://prestashop;#these were from wp, but not usable here, according to:
#https://gist.github.com/chroriginal/8d8ea7d284bcc42055a6ba18c04aeccf
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;#this was from gist, but doesn't work.
#proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#proxy_set_header Host $http_host;
#proxy_set_header X-Forwarded-Proto https;
#from git issues tracker
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
send_timeout 300;}}

Here is the docker-compose.yml:

version: '3'


services:
  nginx:
    image: nginx:latest
    container_name: production_nginx
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf
      - /etc/letsencrypt/:/etc/letsencrypt/
      - ./webroot/:/var/www/html/
    ports:
#be careful with these. Port 80 on container side must match nginx listen port. the host side port, is only for the docker proxy.
      - 80:80
      - 443:443

    restart: always
#    command: [nginx-debug, '-g', 'daemon off;']

  db_prestashop:
    image: mysql:5.7
    environment:
      - MYSQL_ROOT_PASSWORD=xxxxxx
      - MYSQL_USER=xxxxxx
      - MYSQL_PASSWORD=xxxxxx
      - MYSQL_DATABASE=prestashop
    volumes:
      - ./db_data_presta:/var/lib/mysql
      - ./db_conf_presta:/etc/mysql/
    restart: always

  prestashop:
    depends_on:
        - db_prestashop
    image: 'prestashop/prestashop'
    volumes:
       - ./presta_root:/var/www/html/
    environment:
      - DB_SERVER=db_prestashop
      - ADMIN_MAIL=xxxxxx
      - ADMIN_PASSWD=xxxxxx
      - VIRTUAL_HOST=https://URLHERE
      - VIRTUAL_PORT=80
      - PS_DOMAIN=https://URLHERE
      - DB_NAME=prestashop
      - DB_USER=xxxxxx
      - DB_PASSWD=xxxxxx
      restart=always

I don’t believe the DB_NAME or DB_USER variable is used in docker for prestashop. DB config is done at installation. Virtual host likewise, may not be necessary.

use prestashop
SELECT NAME, VALUE FROM ps_configuration WHERE NAME IN ('PS_SSL_ENABLED', 'PS_SSL_ENABLED_EVERYWHERE');
UPDATE ps_configuration SET VALUE = '1' WHERE NAME IN ('PS_SSL_ENABLED', 'PS_SSL_ENABLED_EVERYWHERE');
SELECT NAME, VALUE FROM ps_configuration WHERE NAME IN ('PS_SSL_ENABLED', 'PS_SSL_ENABLED_EVERYWHERE');

Also, one other change on the DB. You should ensure that your shop URL is set to be something like URL.com
You do NOT want https://URL.com in either domain or domain\_ssl in ps\_shop\_url

mysql> select * from ps_shop_url;
+-------------+---------+--------------------------+--------------------------+--------------+-------------+------+--------+
| id_shop_url | id_shop | domain                   | domain_ssl               | physical_uri | virtual_uri | main | active |
+-------------+---------+--------------------------+--------------------------+--------------+-------------+------+--------+
|           1 |       1 | shop.steaky.com | shop.steaky.com | /            |             |    1 |      1 |
