looking for the image amazon/dynamodb-local.
I can find it on hub.docker.com with no issues.
If I go to index.docker.io I can search for it:
But if I click on the link https ://index.docker.io/r/amazon/dynamodb-local I get 404.
Same thing happened to me when I was trying to setup plantuml/plantuml-server image.
Its there in hub.docker.com but not in index.docker.io.
It happened to me in Azure app Service which defaults the registry to index. docker Finally I had to change the registry of Azure App Service
