AWS Examples

Complete workflow examples for running Unity builds on AWS Fargate via Orchestrator.

Minimal AWS Build​

The simplest AWS workflow. Uses default CPU and memory.

name: Build with Orchestrator (AWS)

on:
  push:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          lfs: true

      - name: Configure AWS Credentials
        uses: aws-actions/configure-aws-credentials@v4
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: eu-west-2

      - uses: game-ci/orchestrator@v1.0.0
        with:
          providerStrategy: aws
          targetPlatform: StandaloneLinux64
          gitPrivateToken: ${{ secrets.GITHUB_TOKEN }}

Multi-Platform Matrix Build​

Build for multiple platforms in parallel. Each platform runs as a separate Fargate task.

name: Orchestrator  -  AWS Multi-Platform

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

jobs:
  build:
    name: Build (${{ matrix.targetPlatform }})
    runs-on: ubuntu-latest
    strategy:
      fail-fast: false
      matrix:
        targetPlatform:
          - StandaloneLinux64
          - StandaloneWindows64
          - StandaloneOSX
          - iOS
          - Android
          - WebGL
    steps:
      - uses: actions/checkout@v4
        with:
          lfs: true

      - name: Configure AWS Credentials
        uses: aws-actions/configure-aws-credentials@v4
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: eu-west-2

      - uses: game-ci/orchestrator@v1.0.0
        id: build
        with:
          providerStrategy: aws
          targetPlatform: ${{ matrix.targetPlatform }}
          gitPrivateToken: ${{ secrets.GITHUB_TOKEN }}
          unityVersion: 2022.3.0f1
          containerCpu: 2048
          containerMemory: 8192
          containerHookFiles: aws-s3-upload-build
          githubCheck: true

Custom Resources and S3 Artifacts​

Specify CPU/memory and export build artifacts to S3.

- uses: game-ci/orchestrator@v1.0.0
  id: aws-build
  with:
    providerStrategy: aws
    versioning: None
    projectPath: path/to/your/project
    unityVersion: 2022.3.0f1
    targetPlatform: ${{ matrix.targetPlatform }}
    gitPrivateToken: ${{ secrets.GITHUB_TOKEN }}
    containerCpu: 2048
    containerMemory: 8192
    # Export builds to S3:
    containerHookFiles: aws-s3-upload-build

Valid CPU/Memory Combinations​

AWS Fargate only accepts specific combinations (1024 = 1 vCPU, memory in MB):

CPU (containerCpu)Memory (containerMemory)
256 (0.25 vCPU)512, 1024, 2048
512 (0.5 vCPU)1024 – 4096
1024 (1 vCPU)2048 – 8192
2048 (2 vCPU)4096 – 16384
4096 (4 vCPU)8192 – 30720

Async Mode​

For long builds, use async mode so the GitHub Action returns immediately. Monitor via GitHub Checks.

- uses: game-ci/orchestrator@v1.0.0
  with:
    providerStrategy: aws
    targetPlatform: StandaloneLinux64
    gitPrivateToken: ${{ secrets.GITHUB_TOKEN }}
    asyncOrchestrator: true
    githubCheck: true

Retained Workspaces​

Keep the entire project cached between builds for dramatically faster rebuilds.

- uses: game-ci/orchestrator@v1.0.0
  with:
    providerStrategy: aws
    targetPlatform: StandaloneLinux64
    gitPrivateToken: ${{ secrets.GITHUB_TOKEN }}
    maxRetainedWorkspaces: 3
    containerCpu: 2048
    containerMemory: 8192

S3 Upload + Steam Deploy​

Chain container hooks to export to S3 and deploy to Steam in one step.

- uses: game-ci/orchestrator@v1.0.0
  with:
    providerStrategy: aws
    targetPlatform: StandaloneLinux64
    gitPrivateToken: ${{ secrets.GITHUB_TOKEN }}
    containerHookFiles: aws-s3-upload-build,steam-deploy-client
  env:
    STEAM_USERNAME: ${{ secrets.STEAM_USERNAME }}
    STEAM_PASSWORD: ${{ secrets.STEAM_PASSWORD }}
    STEAM_APPID: ${{ secrets.STEAM_APPID }}

Scheduled Garbage Collection​

Clean up stale CloudFormation stacks and Fargate tasks.

name: Orchestrator  -  Garbage Collect

on:
  schedule:
    - cron: '0 4 * * *' # Daily at 4 AM UTC

jobs:
  cleanup:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Configure AWS Credentials
        uses: aws-actions/configure-aws-credentials@v4
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: eu-west-2

      - uses: game-ci/orchestrator@v1.0.0
        with:
          providerStrategy: aws
          mode: garbage-collect
          garbageMaxAge: 24
          gitPrivateToken: ${{ secrets.GITHUB_TOKEN }}
