🚀 Setup Docker Buildx (Advanced)

Stop wasting CI minutes.
Make Docker builds 2–5x faster with built-in caching and production-grade defaults.

---

✨ Features

• ✅ GHA Cache (zero-config, fastest for CI)
• 📦 Registry Cache (shared across teams)
• 💾 Local Cache (perfect for self-hosted runners)
• ⚙️ Built-in QEMU (multi-arch out of the box)
• 🔁 Idempotent builder creation (safe for reruns)
• 🌍 Remote builder support (k8s / TCP ready)
• 🧠 Smart defaults (works even with minimal inputs)

---

🔥 Why this exists

Most Buildx setups:

• Require multiple actions
• Have fragile caching
• Break on reruns

This action is designed for real-world pipelines:

Faster builds. Fewer failures. More control.

📦 Basic Usage

- name: Setup Buildx
  uses: anantacloud-actions/setup-buildx-action@v1

⚡ With Multi-Arch Support

  uses: anantacloud-actions/setup-buildx-action@v1
  with:
    platforms: linux/amd64,linux/arm64

🔁 Caching Strategies

🧠 GHA Cache (Recommended)

  with:
    cache-type: gha

📦 Registry Cache (Team Sharing)

  with:
    cache-type: registry
    cache-image: myrepo/buildx-cache:latest

💾 Local Cache (Self-hosted runners)

  with:
    cache-type: local
    cache-dir: /tmp/.buildx-cache

🏗️ Build Example (with cache)

- name: Build Image
  run: |
    docker buildx build \
      --cache-from "$BUILDX_CACHE_FROM" \
      --cache-to "$BUILDX_CACHE_TO" \
      --platform linux/amd64,linux/arm64 \
      -t myapp:latest .

📈 Performance Impact

Typical improvements:

• ⏱ 60–90% faster builds
• 💰 Reduced CI costs
• 🔁 Reliable reruns (no flaky builders)
