py-consul 1.7.1

Python client for Consul (http://www.consul.io/)

py-consul

Status

This project is maintained and actively developed by Criteo. We aim at converging towards a full compatibility with the official Consul API.

We're currently supporting consul 1.20 up to 1.22. Due to quite a few changes since our development started (see section "A bit of history"), some endpoints are still partially handled.

Therefore, we are open to contributions and suggestions.

Example

    import consul

    c = consul.Consul()

    # poll a key for updates
    index = None
    while True:
        index, data = c.kv.get('foo', index=index)
        print data['Value']

    # in another process
    c.kv.put('foo', 'bar')

Installation

    pip install py-consul

Note: When using py-consul library in environment with proxy server, setting of http_proxy, https_proxy and no_proxy environment variables can be required for proper functionality.

A bit of history

The origin project python-consul is not maintained since 2018. As we were not able to get in touch with the maintainer (cablehead) to merge and release our PRs, we've forked the project in order to continue the maintenance of the project. We also renamed the project to be able to upload on pypi; see PyPI

Following some major changes, we decided to detach this fork from the original project and move from criteo fork space to criteo space.

Contributing

Please reach out if you're interested in being a maintainer as well. Otherwise, open a PR or Issue we'll try and respond as quickly as possible.

When you create a PR please ensure:

• To add tests for your new features, if applicable
• To add docstrings for new API features you may add
