「GitHub Actions を使用して継続的インテグレーション (CI) ワークフローを作成する」オンライントレーニングを受講してみた

name: Data Sharing Example

on:
  push:
    branches: [ main ]

jobs:
  example-job:
    runs-on: ubuntu-latest
    steps:
      - name: Step 1 - Set and export variable
        # このステップ内でexportした変数は、このステップ内でのみ有効
        run: |
          export STEP1_MESSAGE="Hello from Step 1"         # 環境変数に値をセット
          echo "STEP1_MESSAGE is set to: $STEP1_MESSAGE"   # 同じステップ内では変数の値を表示可能

      - name: Step 2 - Try to access exported variable
        # 異なるステップ間では環境変数は共有されないため、STEP1_MESSAGEは空
        run: |
          echo "Trying to access STEP1_MESSAGE: $STEP1_MESSAGE"  # 出力結果は空になる
          echo "As you can see, STEP1_MESSAGE is not accessible in this step"

      - name: Step 3 - Share data using GITHUB_OUTPUT
        # GITHUB_OUTPUTを使用することで、他のステップでこの値を参照可能になる
        id: share  # このステップにIDを設定し、後で参照できるようにする
        env:
          STEP1_MESSAGE: "Hello from Step 1"  # 環境変数を再度設定
        run: |
          echo "step1_value=$STEP1_MESSAGE" >> $GITHUB_OUTPUT  # GITHUB_OUTPUTを使用してデータを共有
          echo "Data shared using GITHUB_OUTPUT"

      - name: Step 4 - Access shared data
        # 前のステップ（Step 3）で共有された値を参照する
        run: |
          echo "Accessing shared data: ${{ steps.share.outputs.step1_value }}" # steps.{step_id}.outputs.{output_name}の形式で参照できる

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

name: CI

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

  # 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
      - uses: actions/checkout@v4

      # Add Step 2
      - name: Run markdown lint
        run: |
          npm install remark-cli remark-preset-lint-consistent
          npx remark . --use remark-preset-lint-consistent --frail

      # Add Step 3
      - uses: actions/upload-artifact@v4
        with:
          name: remark-lint-report
          path: remark-lint-report.json
