Unable to Push image to docker container registry

Question

I have configured docker container registry and frontend as described here

Container registry (port 9001) and frontend (port 8080) are working without any error, but when I try to push the image after tagging it I am getting error (mentioned below)

$ sudo docker tag nginx:1.17.0 localhost:9001/nginx:reg

$ sudo docker push localhost:9001/nginx:reg

The push refers to repository [localhost:9001/nginx]
Get http://localhost:9001/v2/: read tcp 127.0.0.1:39514->127.0.0.1:9001: read: connection reset by peer

Answer 1

Finally found the issue I was running the container registry on Ports 9001:9001 (host port: registry port) which was wrong, container registry expose services at port 5000 . So I re-ran container registry on Ports 5000:5000 and the issue was resolved
