Docker Multi Architecture Image

Scenario:

You have a Dockerfile at /home/interview/Dockerfile that needs to be built for multiple architectures to support different hardware platforms. Currently, building with docker build only creates images for the host architecture.

Task:

Configure Docker Buildx instance named multiarch with buildx create to build the image for both amd64 and arm64 architectures using Push the multi-arch manifest to localhost:5000/myapp:multi.

Example:

Building for linux/amd64 only

Building for linux/amd64, linux/arm64
Pushing manifest list to localhost:5000/myapp:multi
