CRD Extractor

The CRD Extractor is a Python script that enables you to extract Custom Resource Definitions (CRDs) from a rendered YAML file and save them as a concatenated YAML file. It also separates non-CRD objects into another file.

Prerequisites

  • Python 3.x
  • PyYAML library (pip3 install pyyaml)

Usage

  1. Make sure you have Python 3.x installed on your system.
  2. Install the required PyYAML library by running the following command:
$ pip3 install -r requirements.txt
  1. Run the script by executing the following command:
$ python3 main.py --file <rendered_yaml_file> --path <output_dir>`

Notes

  • The script uses the PyYAML library to load and dump YAML data. Make sure you have installed it before running the script.
  • The script identifies CRDs by checking the kind attribute of each object. Objects with kind set to 'CustomResourceDefinition' are considered as CRDs.
  • The extracted CRDs will be saved in a single file with each CRD separated by --- delimiters.
  • Non-CRD objects will be saved in a separate file with the same --- delimiters.
  • The script will display the paths of the generated files after completion.

Test

$ python3 -m unittest tests.test_extract_crd
