I can't quite grok the image
[registry-url]/[namespace]/[image]:[tag] URL for a Docker Hub image of mine for AWS ECS.
With the Docker client it's just
docker run -it hendry/count.
So what would Docker Hub's URL for the image?
The registry url is … blank. Just the same as the docker command line, if you give ECS an image with no repository url:
it will pull it from dockerhub.
(This surprised me too. I spend half an hour searching the interwebs for a url for dockerhub before trying this).
You're looking in the wrong place. Go to the repositories view. From there, it should be very clear what the URL for your image is.
