Nessy CLI

Simple command line interface to the Nessy locking system.

Installation

It is simplest to install via PyPI using:

pip install nessy-cli

Usage

For convenience, you should set the nessy server claims URL in your environment:

export NESSY_CLAIMS_URL=http://nessy.example.com/v1/claims

If NESSY_CLAIMS_URL or GENOME_NESSY_SERVER are set in your environment, then those will be used; otherwise, you will need to specify the URL on the command line with the --url option.

To list active claims:

nessy list --status active

To revoke claims matching a filter:

nessy revoke --status active --min-active-duration 100000

To avoid a race condition while trying to revoke a specific claim on a resource, you should add a filter on the active duration:

nessy revoke --status active --min-active-duration 100000 --resource <RESOURCE>
