Try summ for three hours
summ is a container registry.
Sign in with GitHub to get a private one of your own at
<name>.cloud.summcr.com: log in, push and pull with
docker, and browse it in summ's web UI.
Each trial has 5 GB of storage. After 3 hours, the registry and any images you've pushed are deleted.
Signing in reads only your public GitHub profile.
