I pushed my docker images to my private registry and was able to list the pushed images using below commands: (i am running my private Docker registry on 5005 port using command => sudo docker run -d -p 5005:5000 --name my-registry registry:2)
sudo docker tag redis localhost:5005/redis
sudo docker push localhost:5005/redis
curl localhost:5005/v2/_catalog
Output from above 3rd catalog command
{“repositories”:[“nginx”,“redis”]}
