A simple Python script to assist with parsing various aspects of the istioctl bug-report output.
Currently, this script can parse custom resources and nodes.
To parse CRs, this script depends on the standard input of a list of CRs under the heading 'items'. If this is not found, the script will fail.
Make sure you have Python3 enabled in your path.
You will need to pip install pyyaml.
python3 ibrp.py <operation> <path-to-your-crd-file>
Operation will be either 'crparse' or 'nodeparse'.
Output will go to the crs directory as a child of the current directory. Each type of custom resource will be created in a directory named by the type of CR.
Note that for production workloads, parsing can take a few minutes. The script will provide output on progress.
Nodes will be parsed to capture the name, roles and cpus. Output will be sent to stdout.
