This tool allows you to compare a customized values.yaml file against the upstream defaults, highlighting the differences.

Table of Contents

Installation

Helm Plugin Installation

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

Then you may access the cli by using the command

helm yamldiff

Manual Installation

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

pip install -r requirements.txt

Usage

Command line interface

Format:

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

Examples

python3 yamldifftool.py test/default_values.yaml test/large_copied_values.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/large_copied_values.yaml with the defaults to produce the following output.

global:
  badOption:
    jesse:
    - hi
    - there
  image:
    tag: 8.2.2
  ingress:
    annotations:
      nginx.ingress.kubernetes.io/ssl-redirect: brrr
  elasticsearch:
    prefix: zeebe-re
  zeebePort: 265
  identity:
    auth:
      webModeler:
        redirectUrl: http:ost:8084
