If I pull latest tag of the image I can get its sha digest
# docker pull mysql:latest
...
Digest: sha256:c93ba1bafd65888947f5cd8bd45deb7b996885ec2a16c574c530c389335e9169
Status: Downloaded newer image for mysql:latest
docker.io/library/mysql:latest
But if I go to the dockerhub there is something different
