Overwrite Env File

This GitHub Action allows you to overwrite the contents of an environment file with the contents of another file. It is useful when you want to promote/stage environment variables from one environment to another (for example, from a .env.development file to a .env.production file) automatically in your workflows.

Usage

- name: Overwrite production env file with development env file
  uses: dev-five-git/overwrite-env-file-action@v1
  with:
    input: .env.development
    output: .env.production

Inputs

Name	Description	Required	Default
input	The file to read from	true	.env.development
output	The file to overwrite to	true	.env.production

  push:
    branches: [main, dev]
