1. Output of caddy version:

2. How I run Caddy:
I use docker compose for running caddy along with another compose for running wordpress.
For the wordpress, I have the following docker-compose:
a. System environment:
OS: Debian 11
Docker version: Docker version 20.10.17, build 100c701
Docker compose: Docker Compose version v2.6.0
b. Command:
docker compose up -d

d. My complete Caddy config:
{
email redacted@example.com
}
import /etc/caddy/Caddyfile.d/*.Caddyfile
Relevant caddy file for wordpress (wordpress.Caddyfile):
{$PROJECT_DOMAIN} {
root * /wordpress
# List of disallowed paths
@disallowed {
path /xmlrpc.php
path *.sql
path /wp-content/uploads/*.php
}
rewrite @disallowed '/index.php'
# Don't allow uploading of .php files to Uploads
respond /uploads/*.php 404
php_fastcgi wordpress:9000
encode gzip
file_server
log {
output file /data/wordpress.log {
roll_size 100
roll_local_time
roll_keep 5
roll_keep_for 720h
}
}
}
www.{$PROJECT_DOMAIN} {
redir https://{$PROJECT_DOMAIN}{uri}
}
3. The problem I’m having:
The folder where the Wordpress code resides is binded to /wordpress in the Caddy docker-compose. But in the Wordpress it is in /var/www/html. When I use the shared configuration, entering the wordpress domain gets me “File not found.” page. This is because it looks at /wordpress instead of /var/www/html. However, If I modify the line - /var/www/docker-wordpress/http:/wordpress in the Caddy’s docker-compose to - /var/www/docker-wordpress/http:/var/www/html and the root to the same folder in the Caddyfile, then it works fine.
I want to do it this way because I will have multiple wordpress sites in different containers. So in the Caddy container there would be /wordpress1, /wordpress2. How coul I route the fastcgi to the root of the container? Is there a way to do this without binding the folders in Caddy’s container?

5. What I already tried:
Binding it to /var/www/html in the Caddy container makes it work fine. But I don’t want this as I can’t have multiple wordpress because internally they all point to /var/www/html and I need to differentiate them.
I also can’t and don’t want to modify the Dockerfile for the wordpress image to change the internal route.
