Define 'latest' tag for docker images

[fangohr]

This doesn't work:

docker run -ti virtualmicromagnetics/lite /bin/bash -l
fangohr$ docker run -ti virtualmicromagnetics/lite /bin/bash -l

Unable to find image 'virtualmicromagnetics/lite:latest' locally
Pulling repository docker.io/virtualmicromagnetics/lite
docker: Tag latest not found in repository docker.io/virtualmicromagnetics/lite.

On the other hand, this is okay:

docker run -ti virtualmicromagnetics/lite:1.1.0 /bin/bash -l

Should "latest" point to the most recent release, to the most recent development build, or to the most recent feature build? I would prefer to change the name of the default container pulled by docker, as "latest" is ambiguous in its functionality.

[fangohr]

Maybe the most recent release?

But in any case it seems to be important that there is some image defined with the tag 'latest' if this is the tag that docker searchers for automatically if the user doesn't specify a particular tag (see error above).
