How to build the Multi-Architecture images

Method 1:

Build an image for each architecture

docker build -t kribakarans/ubuntu:amd64 .
docker build -t kribakarans/ubuntu:arm64 .

Push all images to docker hub repository

docker push kribakarans/ubuntu:amd64
docker push kribakarans/ubuntu:arm64

Create a multi-architecture image

docker manifest create kribakarans/ubuntu:latest kribakarans/ubuntu:amd64 kribakarans/ubuntu:arm64

Push the multi-architecture image

docker manifest push kribakarans/ubuntu:latest

The image is now ready to be pulled regardless of architecture

docker pull kribakarans/ubuntu:latest

Login to the Ubuntu shell

docker run -it kribakarans/ubuntu:latest bash

Method 2: With Buildx tool

docker buildx build --push \
                    --platform linux/amd64,linux/arm64 \
                    --tag kribakarans/ubuntu:latest
