Docker how to commit images with name on repository and tag

I've made the images of Ubuntu 14:04, on my local laptop. Then I want to commit images,

I run this command to commit

 $ sudo Docker commit 2a1aef6a0547

However, there is no name on the repository and TAG

Like this, check images

 $ sudo docker images

The results

 REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
 <none>              <none>              87ab1f8aeb2f        12 minutes ago      5.34 GB
 ubuntu              14.04               e9ae3c220b23        2 weeks ago         187.9 MB

Name repository and tag is <none>

To be able to give a name, use syntax like??

To answer your question following is the syntax:

docker commit -a "Author Name" -m "Commit message" container-id/container-name new-image-name

where -a & -m are optional and / denotes an or condition so it is container id or container name.

example for the same is:

docker commit -a "Some Name Here" -m "Simple nginx hosted on 8080" hello-nginx-container hello-nginx-yj

Now to be able to push this image to docker hub the new-image-name must be prefixed with YOUR_DOCKERHUB_USERNAME/.

I have created an example Docker project, it includes more details about this exact same question in the documentation.

All the links mentioned above are my own github repo links.

Check the docker commit usage parameters:

Usage: docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]

In fact, the example presented there shows how to do this:

$ docker commit c3f279d17e0a  SvenDowideit/testimage:version3
f5283438590d

$ docker images    
REPOSITORY                        TAG                 ID                  CREATED             VIRTUAL SIZE
SvenDowideit/testimage            version3            f5283438590d

Depending on what you are trying to do though - you may wish to start building images from a(n) (existing) Dockerfile instead.
