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)
