+ABOUT
+=====
+Docker container for HA-Proxy.
+
+
+AUTHOR
+======
+Jens Kleineheismann <heinzel@heinzelwelt.de>
+
+
+DESCRIPTION
+===========
+This docker image is derivated from the official Fedora image
+(https://hub.docker.com/_/fedora).
+
+It will contain and run
+
+- haproxy
+
+
+BUILD
+=====
+- ``make``
+- ``make test``
+
+or alternatively the *long* way:
+
+- ``docker build -t haproxy .``
+- ``dgoss run haproxy``
+
+
+USAGE
+=====
+- ``docker run -d -p 80:80 haproxy``
+
+The httpd process is listening on port 80/tcp.
+
+The httpd error log will be written to stderr, so it can be
+obtained with ``docker logs``
+
+
+CONFIGURATION
+=============
+The following **environment variables** are supported and
+can be set with the -e option of the ``docker run`` command:
+
+- LOG_LEVEL (default: error)
+  -- to set the httpd LogLevel directive
+
