The image is stored on Docker Hub at the docker/welcome-to-docker repo.
For the latest tag, we are using the small-image branch to make the first walkthrough user experience optimal. Any changes in main should be merged into small-image also.
To push a change to the welcome-to-docker Hub image:
git checkout small-image
docker buildx create --name mybuilder --use --bootstrap # only if not created before
docker buildx build --push --platform linux/amd64,linux/arm64 --tag docker/welcome-to-docker .
