Simple tool to generate a haproxy config file based on etcd and gracefully reload haproxy.

Objective is to dynamically update haproxy.cfg with new servers on each backend (when registred with etcd) and reload haproxy.

Simply run:

$ pip install .

To use it:

$ haproxy-etcd --help

Important: Services are expected to be registred at /keys/services; For each service instance, the expected value is formatted as [HOST|IP]:PORT

e.g. for a service named api, a GET from /keys/services/api could return the following instances/nodes:

{
    "action": "get",
    "node": {
    "key": "/services/api",
    "dir": true,
    "nodes": [
        {
        "key": "/services/api/172.10.0.1",
        "value": "172.10.0.1:80",
        "modifiedIndex": 4,
        "createdIndex": 4
        },
        {
        "key": "/services/api/172.10.0.2",
        "value": "172.10.0.2:80",
        "modifiedIndex": 5,
        "createdIndex": 5
        }
    ],
    "modifiedIndex": 4,
    "createdIndex": 4
    }
}
