A Github Action to create a .env file with Github Secrets. This is useful when you are creating artifacts that need to contain secrets stored in Github Secrets. This creates a file with variables that are defined in the Action config.

The Action looks for environment variables that start with envkey_ and creates an envfile with them. These are defined in the with section of the Action config. Here is an example of it in use:

name: Create envfile

on: [push]

jobs:

  create-envfile:
 
    runs-on: ubuntu-18.04
 
    steps:
    - name: Make envfile
      uses: creatrip/create-envfile@v2
      with:
        envkey_DEBUG: false
        envkey_SOME_API_KEY: "123456abcdef"
        envkey_SECRET_KEY: ${{ secrets.SECRET_KEY }}
        some_other_variable: foobar
        directory: <directory_name>
        file_name: .env

In the example above, there are several key/value pairs that will be added to the envfile:

Assuming that the Github Secret that was used is password123, the .env file that is created from the config above would contain:

DEBUG: false
SOME_API_KEY: "123456abcdef"
SECRET_KEY: password123

When the Action runs, it will show Warning: Unexpected input(s) .... This is because Github is expecing all the potential input variables to be defined by the Action's definition.
