create multiple tag docker image

Question

How can several tags be attached to one Docker image? Is it possible to create multiple tags using one Dockerfile?

It is possible, somehow; for example docker pull ubuntu will get several images, some of which have multiple tags:

Since 1.10 release, you can now add multiple tags at once on build:

docker build -t name1:tag1 -t name1:tag2 -t name2 .
