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              latest              d583c3ac45fd        26 minutes ago      685.5 MB

Hence I want to change the name server to something like myname/server:

REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
myname/server       latest              d583c3ac45fd        26 minutes ago      685.5 MB

How can I do this?

Answer 1

docker tag server:latest myname/server:latest

or

docker tag d583c3ac45fd myname/server:latest

Tags are just human-readable aliases for the full image name (d583c3ac45fd...).

So you can have as many of them associated with the same image as you like. If you don't like the old name you can remove it after you've retagged it:

docker rmi server

That will just remove the alias/tag. Since d583c3ac45fd has other names, the actual image won't be deleted.

Answer 2

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 3

docker tag CURRENT_IMAGE_NAME DESIRED_IMAGE_NAME

Answer 4

Recently I had to migrate some images from Docker registry (docker.mycompany.com) to Artifactory (docker.artifactory.mycompany.com)

docker pull docker.mycompany.com/something/redis:4.0.10
docker tag docker.mycompany.com/something/redis:4.0.10 docker.artifactory.mycompany.com/something/redis:4.0.10
docker push docker.artifactory.mycompany.com/something/redis:4.0.10

Answer 5

docker run -it --name NEW_NAME Existing_name

To change the existing image name.
