Chronos CLI

A Command-line Interface for Chronos v3.

Installation

Directly from GitHub:

# latest version (use @version for specific version)
$ pip install git+ssh://[email protected]/aparenton/chronos-cli.git

Or, install from the sources after cloning:

$ python setup.py install

Configuration

Chronos CLI supports both YAML and JSON (see config):

stage:
  url: YOUR_CHRONOS_STAGE_URL
  username: YOUR_CHRONOS_STAGE_USERNAME
  password: YOUR_CHRONOS_STAGE_PASSWORD
prod:
  url: YOUR_CHRONOS_PROD_URL
  username: YOUR_CHRONOS_PROD_USERNAME
  password: YOUR_CHRONOS_PROD_PASSWORD

By default, Chronos CLI will read from:

  • ~/.config/chronos/config.json or
  • ~/.config/chronos/config.yaml or
  • ~/.config/chronos/config.yml

But you can choose a specific configuration file with --config my-config.yaml.

Chronos artifact

A simple Chronos artifact (see examples for more detailed samples):

{
  "schedule":"R/2015-11-09T00:00:00Z/PT24H",
  "name":"test-1",
  "epsilon":"PT30M",
  "command":"echo test1 && sleep 60",
  "owner":"[email protected]",
  "async":false
}

Note: see Chronos documentation for ISO 8601 format for scheduling the job.

    "code": 204
}
