docker push to private registry - An image does not exist locally with the tag: localhost:5000/xxxx

I have running private registry

sudo docker run -d -p 5000:5000 --restart always --name registry registry:2
sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1707fb042a43 registry:2 "/entrypoint.sh /etc…" 4 days ago Up 2 hours 0.0.0.0:5000->5000/tcp, :::5000->5000/tcp registry

I have image need to push to my private registry

sudo docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
coinbase latest 7bfb7cc3d51c 11 months ago 781MB

When I try to push my image to my private registry

sudo docker push localhost:5000/coinbase:latest

docker answer me:

The push refers to repository [localhost:5000/coinbase]
An image does not exist locally with the tag: localhost:5000/coinbase

Why? It looks as don't understanding that localhost:5000 is URL of my private registry. Where is mistake?

You need to tag your image with registry host included

docker image tag coinbase:latest localhost:5000/coinbase:latest

Check docker push documentation for details and examples.
