supervisor-haproxy 1.1.0

Configuration

When the egg supervisor-haproxy is installed, the supervisor event listener is created as console script supervisor-haproxy. It needs to be configured in the supervisor configuration and requires the haproxy stats socket and the program infos in order to work correctly.

The program infos have the form supervisorProgram:HaProxyBackend/HaProxyServer, for example instance2:plone04/plone0402 and tell the event listener which program in supervisor is which backend server in haproxy.

First configure a stats socket in the haproxy config:

global
    stats socket ipv4@127.0.0.1:8801 level admin

then configure the supervisor haproxy event listener in the supervisor config:

[eventlistener:HaProxy]
command = .../bin/supervisor-haproxy tcp://localhost:8801 instance1:plone01/plone0101 instance2:plone01/plone0102
events = PROCESS_STATE
process_name=HaProxy

Example using buildout for configuring supervisor:

[supervisor]
plugins +=
    supervisor-haproxy
eventlisteners +=
    HaProxy PROCESS_STATE ${buildout:bin-directory}/supervisor-haproxy [tcp://localhost:8801 instance1:plone01/plone0101 instance2:plone01/plone0102]

Development / Tests

For development and running tests you need to install:

• tox in order to run the tests.

• docker so that the tests can set up a haproxy for testing against.

After installing tox and docker you can clone the repository and run the tests with the tox command:

$ git clone git@github.com:4teamwork/supervisor-haproxy.git
$ cd supervisor-haproxy
$ tox

While running the tests, the haproxy in docker will be bound to the port 9902, so you need to make sure that this port is available.
