Setup workflow files

production.yml

# This is a basic workflow to help you get started with Actions

name: CD

# Controls when the action will run. Triggers the workflow on push or pull request
# events but only for the master branch
on:
  push:
    branches: [master]
  pull_request:
    branches: [master]

# A map of environment variables that are available to all jobs and steps in the workflow
env:
  AWS_ENVIRONMENT_NAME: nest-production
  AWS_DEFAULT_REGION: ap-northeast-1

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  build:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it

Replace AWS_ENVIRONMENT_NAME with your environment of the elastic beanstalk application. Replace AWS_DEFAULT_REGION with the region where you created your elastic beanstalk application.

Add AWS secrets to Github

Push code to Github then Github Action will deploy your app to aws automatically
