Github Action to create a dotenv file

The action looks for environment variables that start with INPUT_ENVKEY_ and creates an envfile with them. To add a key to the envfile, add a key/pair to the with: section. It must begin with ENVKEY.

with:
  envkey_DEBUG: false
  envkey_SOME_API_KEY: "123456abcdef"
  envkey_SECRET_KEY: ${{ secrets.SECRET_KEY }}

  some_other_variable: foobar # Won't be used

  directory: <directory_name>
  file_name: .env

In this example, there are 6 keys:

envkey_DEBUG, envkey_SOME_API_KEY - String values

envkey_SECRET_KEY - A secret stored in the repository's Github Secrets

some_other_variable - Won't be used because it doesn't start with envkey_

directory(Optional) - This key will set the directory in which you want to create env file. (Action will fail if the specified directory doesn't exist.)

file_name(Optional) - Set the name of the output envfile. Defaults to .env
