+# apache-git-http-backend
+
+The apache-git-http-backend docker image serves as receiver in git replication
+from a Gerrit to a Gerrit replica.
+
+## Content
+
+* base image
+* Apache webserver
+* Apache configurations for http
+* git (via base image) and git-deamon for git-http-backend
+* `tools/project_admin.sh`: cgi script to enable remote creation/deletion/HEAD update
+  of git repositories. Compatible with replication plugin.
+* `tools/start`: start script, configures and starts Apache
+ webserver
+
+## Setup and Configuration
+
+* install Apache webserver, additional Apache tools and git daemon
+* configure Apache
+* install cgi scripts
+* map volumes
+
+## Start
+
+* start Apache git-http backend via start script `/var/tools/start`

+# This is the main Apache HTTP server configuration file.  It contains the

+# In particular, see
+# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>

+# Do NOT simply read the instructions in here without understanding

+# consult the online docs. You have been warned.
+#
+# Configuration and logfile names: If the filenames you specify for many
+# of the server's control files begin with "/" (or "drive:/" for Win32), the
+# server will use that explicit path.  If the filenames do *not* begin
+# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
+# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
+# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"
+# will be interpreted as '/logs/access_log'.
+
+#
+# ServerTokens
+# This directive configures what you return as the Server HTTP response
+# Header. The default is 'Full' which sends information about the OS-Type
+# and compiled in modules.
+# Set to one of:  Full | OS | Minor | Minimal | Major | Prod
+# where Full conveys the most information, and Prod the least.
+#
+ServerTokens OS
+
+#
+# ServerRoot: The top of the directory tree under which the server's
+# configuration, error, and log files are kept.
+#
+# Do not add a slash at the end of the directory path.  If you point
+# ServerRoot at a non-local disk, be sure to specify a local disk on the
+# Mutex directive, if file-based mutexes are used.  If you wish to share the
+# same ServerRoot for multiple httpd daemons, you will need to change at
+# least PidFile.
+#
+ServerRoot /var/www
+
+#
+# Mutex: Allows you to set the mutex mechanism and mutex file directory
+# for individual mutexes, or change the global defaults
+#
+# Uncomment and change the directory if mutexes are file-based and the default
+# mutex file directory is not on a local disk or is not appropriate for some
+# other reason.

+# Listen: Allows you to bind Apache to specific IP addresses and/or
