Render yml/yaml files action

This action retrieves secrets and variables from the GitHub context and replaces with values in file(s) (yml/yaml extensions) stated in target parameter if it finds a string with ENV_ prefix that is ENV_<variable/secret name>. If file parameter is given true then it processes single file provided in target, if not it processes files in folder given in target parameter.

variables-context

The variables context which has environment variables in it. (${{ toJson(vars) }})

Outputs

Example usage

uses: ftasbasi/renderfile@v1.9
with:
  secrets-context: ${{ toJson(secrets) }}
  variables-context: ${{ toJson(vars) }}
  target: foldername/filename
  file: true # default false
env:
  VAR1: "sample value" # for changing ENV_VAR1 in files

Let's say we provide ENVIRONMENT_NAME=test-env and STORAGE_SIZE=20Gi as env parameter or a GitHub environment variable directly, here is the sample output:

Before:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  namespace: ENV_ENVIRONMENT_NAME
  name: postgresql-ENV_ENVIRONMENT_NAME
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: manual
  resources:
    requests:
      storage: ENV_STORAGE_SIZE

After:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  namespace: test-env
  name: postgresql-test-env
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: manual
  resources:
    requests:
      storage: 20Gi
