Update for Container Deployment (Important)
Heroku has recently updated their container deployment process. While the multi-architecture images you built in the last lesson are valuable for general Docker knowledge and will work across different platforms, we'll actually rebuild the images specifically for Heroku deployment in the final lesson using their updated requirements.
Keep your multi-architecture images in your Docker Hub repository as a reference and accomplishment - they demonstrate important containerization concepts. The Heroku-specific build process in the deployment lesson will ensure optimal compatibility with their current platform.
