configure-argocd-automerge（配置 argocd 自动合并）

/configure:argocd-automerge

Configure GitHub Actions workflow to automatically create and merge PRs from ArgoCD Image Updater branches.

When to Use This Skill

Context

• Workflows dir:!find. -maxdepth 1 -type d -name \'.github/workflows\'
• Existing automerge workflow:!find.github/workflows -maxdepth 1 \(-name '*argocd*automerge*' -o -name '*automerge*argocd*' \)
• Image updater branches:!git branch -r --list 'origin/image-updater-*'
• Auto-merge workflow:!find.github/workflows -maxdepth 1 -name 'argocd-automerge.yml'

Parameters

Parse from command arguments:

• --check-only: Report status without offering fixes
• --fix: Create or update workflow automatically

Execution

Execute this ArgoCD auto-merge workflow configuration:

Step 1: Detect existing workflow

1. Check for .github/workflows/ directory
2. Search for existing ArgoCD auto-merge workflow files
3. Check for image-updater-** branch pattern handling in any workflow

Step 2: Check compliance

Validate the workflow against these standards:

Step 3: Report results

Print a status report:

ArgoCD Auto-merge Workflow Status
======================================
Workflow: .github/workflows/argocd-automerge.yml

Status:
  Workflow exists     [PASS|FAIL]
  checkout action     [version]         [PASS|WARN]
  Permissions         [explicit|missing] [PASS|FAIL]
  Branch pattern      [pattern]         [PASS|WARN]
  Auto-merge          [strategy]        [PASS|INFO]

Overall: [PASS|FAIL|WARN]

If --check-only, stop here.

Step 4: Configure workflow (if requested)

If --fix flag is set or user confirms, create or update .github/workflows/argocd-automerge.yml with the standard template:

name: Auto-merge ArgoCD Image Updater branches

on:
  push:
    branches:
      - 'image-updater-**'

permissions:
  contents: write
  pull-requests: write

jobs:
  create-and-merge:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Create Pull Request
        id: create-pr
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: |
          PR_URL=$(gh pr create \
            --base main \
            --head "${{ github.ref_name }}" \
            --title "chore(deps): update container image" \
            --body "Automated image update by argocd-image-updater.

          Branch: \`${{ github.ref_name }}\`" \
            2>&1) || true

          # Check if PR already exists
          if echo "$PR_URL" | grep -q "already exists"; then
            PR_URL=$(gh pr view "${{ github.ref_name }}" --json url -q .url)
          fi

          echo "pr_url=$PR_URL" >> "$GITHUB_OUTPUT"
          echo "Created/found PR: $PR_URL"

      - name: Approve PR
        env:
          GH_TOKEN: ${{ secrets.AUTO_MERGE_PAT || secrets.GITHUB_TOKEN }}
        run: gh pr review --approve "${{ github.ref_name }}"
        continue-on-error: true

      - name: Enable auto-merge
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: gh pr merge --auto --squash "${{ github.ref_name }}"

Configuration Notes

Self-Approval

GitHub prevents workflows from approving their own PRs with GITHUB_TOKEN. Options:

Branch Protection

Ensure branch protection allows:

• Auto-merge when checks pass
• Bypass for the workflow (if using CODEOWNERS)
