Patch YAML inside YAML

This github action patches YAML file properties at a given path. It is also able to patch properties of stringified YAML inside YAML files like this:

level1:
  primitive: "primitive value"
  level2:
    yamlInsideYaml: |
      backend:
        image:
          tag: "1.0.0"
    yamlInsideYamlArray: |
      apps:
        - app: service_a
          tag: "1.0.0"
        - app: frontend
          tag: "1.0.0"
  array:
    - app: service_b
      tag: "1.0.0"
    - app: service_c
      anotherYamlInsideYaml: |
        service_d:
          image:
            tag: "1.0.0"
    - app: service_e
      anotherYamlInsideYamlArray: |
        apps:
          - app: service_f
            tag: "1.0.0"
          - app: service_g
            tag: "1.0.0"
    

Usage

Input params

Input	Type	Required	Description
documentFile	string	yes	The path to the YAML file to be patched
yamlPath	string	yes	The YAML path of the property to be patched, for example: level1.level2.yamlInsideYaml
yamlInsideYamlPath	string	no	The optional YAML path of the property to be patched inside the stringified YAML at yamlPath, for example: backend.image.tag
newValue	any	yes	The new value

Example:

jobs:
  deployToProduction:
    steps:
      - run: git clone https://argo-cd.example.com/orchestration.git
      - name: Patch ArgoCD application manifest
        uses: rkretzschmar/patch-yaml-inside-yaml@v2
        with:
          documentFile: ./production/application.yaml
          yamlPath: spec.source.helm.values
          yamlInsideYamlPath: image.tag
          newValue: 1.12.0

With arrays

        with:
          documentFile: ./production/application.yaml
          yamlPath: level1.array[?(@.app=='service_e')].anotherYamlInsideYamlArray
          yamlInsideYamlPath: apps.[?(@.app=='service_f')].tag
          newValue: 1.12.0
