This is to allow podman to automatically pull images from dockerhub without explicitly indicating docker.io
eg: podman pull ubuntu will pull ubuntu image from dockerhub

This is to allow docker to login or pull from insecure registries (without https) or when then local system does not have a SSL certificate trust with destination registry

}
