  run: ./scripts/deployment/production/build-and-push.sh

Issues: - Only built for linux/amd64 - No ARM64 support (Apple Silicon, ARM servers) - Script-based build prone to errors - No build caching - No image metadata/labels

After (New Process)

# Multi-architecture build with QEMU
- name: Set up QEMU
  uses: docker/setup-qemu-action@v3
  with:
    platforms: linux/amd64,linux/arm64

- name: Set up Docker Buildx
  uses: docker/setup-buildx-action@v3
  with:
    platforms: linux/amd64,linux/arm64

- name: Build and push backend image (multi-arch)
  uses: docker/build-push-action@v5
  with:
    platforms: linux/amd64,linux/arm64
    cache-from: type=registry,ref=...:buildcache
    cache-to: type=registry,ref=...:buildcache,mode=max
    labels: |

After (New Process)

VERSION file at repository root:
  0.0.3-beta

Automatically updated by release script:

  release:
    types: [published]
  workflow_dispatch:  # Manual trigger!
    inputs:
      tag:
        description: 'Version tag'
        required: true

# Rich steps with metadata
- Set IMAGE_TAG and metadata (version, date, commit)
