The accepted answer is great for single renames, but here is a way to rename multiple images that have the same repository all at once (and remove the old images).

If you have old images of the form:

$ docker images
REPOSITORY               TAG                 IMAGE ID            CREATED             SIZE
old_name/image_name_1    latest              abcdefghijk1        5 minutes ago      1.00GB
old_name/image_name_2    latest              abcdefghijk2        5 minutes ago      1.00GB

And you want:

new_name/image_name_1
new_name/image_name_2

Then you can use this (subbing in OLD_REPONAME, NEW_REPONAME, and TAG as appropriate):

OLD_REPONAME='old_name'
NEW_REPONAME='new_name'
TAG='latest'

# extract image name, e.g. "old_name/image_name_1"
for image in $(docker images | awk '{ if( FNR>1 ) { print $1 } }' | grep $OLD_REPONAME)
do \
  OLD_NAME="${image}:${TAG}" && \
  NEW_NAME="${NEW_REPONAME}${image:${#OLD_REPONAME}:${#image}}:${TAG}" && \
  docker image tag $OLD_NAME $NEW_NAME && \
  docker rmi $image:${TAG}  # omit this line if you want to keep the old image
done

docker image tag server latest myname server latest   or  docker image 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

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

To rename an image  you give it a new tag  and then remove the old tag using the    rmi    command     docker tag     docker rmi   This second step is scary  as    rmi    means    remove image     However  docker won   t actually remove the image if it has any other tags  That is  if you were to immediately follow this with  docker rmi   then it would actually remove the image  assuming there are no other tags assigned to the image
