Github Action + Unity

1. Github Action 

- 사용 이유 : Jenkins를 시도해보기 전에 Github에서 무료로 바로 쓸 수 있는 Action으로 테스트

- Jenkins대비 장점 : Jenkins는 Cloud 환경이나, Local환경을 따로 구축해야하지만 따로 구축 없이 사용 가능하고, Github와 연동 용이

- 단점 : output 으로 만들어지는 Artifact 기준 누적 billing이여서 게임 빌드시 쉽게 Free 용량 초과

- Billing (https://docs.github.com/en/billing/managing-billing-for-github-actions/about-billing-for-github-actions)

About billing for GitHub Actions

2. 구축

- 사전 준비 : Unity Project가 올라간 Github Repo

 

2-1 Github Actions 탭에서  set up a workflow yourself를 누르면 `.github/workflows/`에 yml 파일을 만들어 셋팅할 수 있다. 

 Console창이 아닌 Project commit 시에 해당 위치에 파일 추가시 Action workflow가 생성된다.

Github Actions

workflows .yml file

2-2 GameCi Action 을 활용 (https://game.ci/docs/github/getting-started)
Activation.yml을 만들어 Unity License를 얻는다

## .github/workflows/activation.yml

name: Acquire activation file
on:
  push: { branches: [release] }
jobs:
  activation:
    name: Request manual activation file 🔑
    runs-on: ubuntu-latest
    steps:
      # Request manual activation file
      - name: Request manual activation file
        id: getManualLicenseFile
        uses: game-ci/unity-request-activation-file@v2
        with: 
          unityVersion: "2021.2.1f1"
      # Upload artifact (Unity_v20XX.X.XXXX.alf)
      - name: Expose as artifact
        uses: actions/upload-artifact@v2
        with:
          name: ${{ steps.getManualLicenseFile.outputs.filePath }}
          path: ${{ steps.getManualLicenseFile.outputs.filePath }}

workflow를 돌린후 나온 alf파일을

license.unity3d.com 에서 ulf파일로 변환하여 받은후

Github > <Your repository> > Settings > Secrets. 에서 UNITY_LICENSE 로 키값을 추가한다.
