Simple command line interface to the Nessy locking system.
It is simplest to install via PyPI using:
pip install nessy-cli
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>
