Ever see a massive customized values.yaml and only want to see how it differs from upstream?

Helm plugin installation

helm plugin install https://github.com/jessesimpson36/yamldifftool.git

Then you may access the cli by using the command

helm yamldiff

instead of python3 yamldifftool.py ...

Installation

To run the application, you need python3 installed and to run

pip install -r requirements.txt

Info

Format:

python3 yamldifftool.py <base_values.yaml>  <customized_values.yaml> --output <output_filename>

python3 yamldifftool.py test/default_values.yaml test/ugly.yaml --output test/output.yaml

A new file will be written named test/output.yaml (or you can specify your own filename with -o)

The new file will only contain entries without the defaults.

In this case, compare the contents of test/ugly.yaml with the defaults to produce the following output.
