Docker how to change repository name or rename image?

Question

I\'m trying to change repository name of the image:

REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
server               


        

Answer 1

As a shorthand you can run:

docker tag d58 myname/server:latest

Where d58 represents the first 3 characters of the IMAGE ID,in this case, that's all you need.

Finally, you can remove the old image as follows:

docker rmi server

Answer 2

docker run -it --name NEW_NAME Existing_name

To change the existing image name.
