pc에서 제작한 코드를 github로 push 한후에 

push 된 소스코드를 master로 병합하면 

개발서버로 병합한 소스코드가 적용되게 하는 스크립트입니다. 

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

name: CH GROUP 개발서버 CI

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

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  # This workflow contains a single job called "build"
  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

이렇게 작성을 해서 실행하면

ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

오류가 납니다. 

어떻게 해결해야 할까요?
