A tool to interact with HAProxy via stats socket
.. haproxytool .. README.rst
haproxytool
*A tool to manage HAProxy via stats socket.*
It uses haproxyadmin <https://github.com/unixsurfer/haproxyadmin>_
Python library to interact with HAProxy and run all commands.
One of the main feature is that can work with HAProxy in multi-process mode (nbproc > 1)
.. contents::
Examples
Usage
The command line interface tries to be friendly and compatible with the rest of
the tools available in the Linux land. The `docopt Python module
<https://pypi.python.org/pypi/docopt>`_ is used to build the CLI interface.
Here is the basic syntax to start with::
% haproxytool
Usage: haproxytool [-v | -h] <command> [<args>...]
% haproxytool -h
A tool to manage HAProxy via the stats socket.
Usage: haproxytool [-v | -h] <command> [<args>...]
Options:
-h, --help show this screen.
-v, --version show version.
Available haproxytool commands are:
haproxy HAProxy operations
frontend Frontend operations
backend Backend operations
server Server operations
dump Dumps all informations
map Manage MAPs
acl Manage ACLs
See 'haproxytool help <command>' for more information on a specific command.
Keep reading for more details about each command.

git tag -s 0.1.3 -m 'bump release'
#. Create the source distribution archive (the archive will be placed in the
**dist** directory)::
python setup.py sdist
#. pbr updates ChangeLog file and we want to squeeze this change to the
previous commit, thus run::
git commit -av --amend
#. Move current tag to the last commit::
git tag -fs 0.1.3 -m 'bump release'
#. Push changes::
git push;git push --tags
Installation
------------
