Python client for Consul Service Discovery API

Project description

Consul Service Discovery API

This module provides a simple way to work with the Consul Service Discovery API from python.

Examples

Usage examples:

import consul
service = consul.Client()
service.register(id='flexlm1', name='flexlm',
            address='10.112.0.211', port=28518,
            tags=('flexlm1', light', 'v1'),
            check={'id': 'flexlm', 'name': 'flexlm on port 28518',
                   'tcp': '10.112.0.211:28518',
                   'Interval': '30s', 'timeout': '2s'})
service.deregister(id='flexlm1')
service.list()
service.info(name='flexlm')

The registration/deregistration is done using the consul agent API:

http://localhost:8500
PUT /v1/agent/service/register
DELETE /v1/agent/service/deregister/<serviceId>

To query the information the catalog API is used:

http://localhost:8500
GET /v1/catalog/services
GET /v1/catalog/service/bigdata
GET /v1/catalog/nodes
GET /v1/catalog/node/c13-9

The payload for the registration request has the following format:

{
  "ID": "flexlm1",
  "Name": "flexlm",
  "Tags": ["flexlm1", light", "v1"],
  "Address": "10.112.0.211",
  "Port": 28518,
  "Check": {
    "id": "flexlm",
    "name": "flexlm on port 28518",
    "tcp": "10.112.0.211:28518",
    "Interval": "30s",
    "timeout": "2s"
  }
}
