Thanks for the fix @Kunnik!

This will break existing user's tags right? I think we should call this out in the readme as well. @srebhan thoughts?

[srebhan]

@powersj I think it will filter out some instances that were output before. If you for example had two containers something/a and a it will now only output a and omits something/a. At least this is my understanding...

Yeap, as was said in the issue I posted in the summary, docker sometimes report more container names for the one container in weird format "/container1/container2". At least in our case, there is always correct container name next to this complicated names in the array.
