What is krakenctl?

https://github.com/kraken-hpc/krakenctl

krakenctl is a command-line tool for viewing and manipulating running kraken instances.

Running

krakenctl is Python3 based. It requires Python >= 3.7.

  1. Verify python version (must be >= 3.7):
    $ python3 --version
    Python 3.9.2
    
  2. Install dependencies:
    $ pip3 install pyyaml requests rich
    ...
    
  3. Run
    ./krakenctl.py -h
    usage: krakenctl.py [-h] [-v] [-d] [-i IP_ADDRESS] action ...
       
    positional arguments:
      action                Desired action to perform
        node                Get node details and manipulate node config
        sme                 Control the kraken SME
        runtime             Change kraken runtime settings
       
    optional arguments:
      -h, --help            show this help message and exit
      -v, --verbose         Provides more details (default: False)
      -d, --debug           Provides details of what krakenctl is doing (default: False)
      -i IP_ADDRESS, --ip IP_ADDRESS
                            IP address of Kraken instance (default: 127.0.0.1:3141)
    

Running with podman (or docker)

Note: instructions are for podman, but should work for docker as well.

  1. Make sure podman is installed and functional.

  2. podman pull docker.io/krakenhpc/krakenctl:latest

  3. alias krakenctl="podman run --rm -it --network=host krakenctl -i 127.0.0.1:3141"

    Replace 127.0.0.1:3141 with the IP/port for your kraken restapi if it’s not running on localhost.

  4. Now run it!

       $ krakenctl -h
    usage: krakenctl.py [-h] [-v] [-d] [-i IP_ADDRESS] action ...
    
    positional arguments:
      action                Desired action to perform
        node                Get node details and manipulate node config
        sme                 Control the kraken SME
        runtime             Change kraken runtime settings
    
    optional arguments:
      -h, --help            show this help message and exit
      -v, --verbose         Provides more details (default: False)
      -d, --debug           Provides details of what krakenctl is doing (default: False)
      -i IP_ADDRESS, --ip IP_ADDRESS
                            IP address of Kraken instance (default: 127.0.0.1:3141)
