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

3. 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
