[qemu-web PATCH] include Dockerfile used to proxy qemu.org to gitlab.io

[Paolo Bonzini]

The server configuration used to actually publish qemu-web.git
to qemu.org together with the sphinx documentation, right now,
is hidden in the machine that runs qemu.org.

Include it in the qemu-web.git website for documentation purpose,
in the format of a Dockerfile that you can use to run your own
qemu.org website.

Note: this container is not yet in use, but it is already live
and can be tested by adding

20.218.253.93   qemu.org www.qemu.org git.qemu.org qemu-project.org 
www.qemu-project.org git.qemu-project.org

to your /etc/hosts file.

+This is a Dockerfile for a container that serves the following hosts:
+
+- qemu.org, www.qemu.org: a proxy server that "hides" the fact that
+  the QEMU web pages are actually hosted as GitLab pages under either
+  qemu-project.gitlab.io/qemu (the documentation) or
+  qemu-project.gitlab.io/qemu-web (the main website)
+
+- git.qemu.org: a simple redirect to gitlab.com/qemu-project for
+  both web browsers and git's smart HTTP backend
+
+
+A sample systemd service that publishes the website on port 8082
+is as follows:
+
+```
+[Unit]
+Description=Podman instance control service for Apache proxy server
+Requires=network.target
+After=network.target
+StartLimitIntervalSec=0
+
+[Service]
+Restart=always
+ExecStartPre=-podman stop qemu-web ; -podman rm qemu-web
+ExecStart=podman run --name qemu-web --publish=8082:80 qemu:qemu-web
+ExecStop=podman stop -t 10 qemu-web
+RestartSec=60
+
+[Install]
+WantedBy=default.target
