Thanks to VonC's answer I managed to get it working but I slightly changed my architecture, resulting in 3 containers instead of only 1.
I have one container for each Apache / PHP version, and one container with Nginx as reverse proxy. I think you can easily adapt this to install Nginx on the host and change it's configuration to match the architecture I described in my question.
Note that as I'm new to Docker, and a noob regarding Linux system administration, there's probably some mistakes and things that don't make any sense in the following scripts, but it's working for me. Feel free to improve it :)
Nginx Reverse Proxy image
The Dockerfile :
FROM debian:jessie
MAINTAINER AntoineB version: 0.1
RUN apt-get update &&
apt-get install -y --force-yes
nginx
nano
EXPOSE 80
EXPOSE 443
ADD ./proxy.conf /etc/nginx/conf.d/proxy.conf
CMD ["nginx"]
Here's the referenced proxy.conf
file :
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
client_header_buffer_size 64k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 16k;
proxy_buffers 32 16k;
proxy_busy_buffers_size 64k;
And I run it using the following bash script :
docker run -ti -d -p 80:80 -v /home/antoineb/Docker/images/nginxproxy/virtualhosts:/etc/nginx/sites-enabled --name nginxproxy nginxproxy /bin/bash
I have a /home/antoineb/Docker/images/nginxproxy/virtualhosts
folder on my host that contains the following default
file :
server {
listen 80;
server_name siteZ.com;
location / {
proxy_pass http://apache22php53:80;
}
}
server {
listen 80;
server_name siteA.com;
location / {
proxy_pass http://apache24php56:80;
}
}
server {
listen 80;
server_name siteB.com;
location / {
proxy_pass http://apache24php56:80;
}
}
Apache 2.2 + PHP 5.3 image

EXPOSE 80
EXPOSE 443
CMD /usr/sbin/apache2ctl -D FOREGROUND
I'm launching it using the following script :
docker run -ti -d -p 2253:80 -v /home:/home -v /home/antoineb/Docker/images/apache22php53/virtualhosts:/etc/apache2/sites-enabled --name apache22php53 apache22php53 /bin/bash
My websites are stored in /home/website.com/www, and my apache virtualhosts are stored on the host in /home/antoineb/Docker/images/apache22php53/virtualhosts
.
Apache 2.4 + PHP 5.6.9 image

FROM debian:jessie
MAINTAINER AntoineB version: 0.1
