Never use Packer.Io for Docker Only

Lasttime i see more often people using from my bro mitchell for building only DOCKER.IO Containers but thats a totally wrong thing

The Only Usefull Reason for Using Packer.Io is and will always be to deploy a Application to more then one service where docker is not running on all Machines. Or Probally for Testing on Diffrent Machines a Application.

But if you use it to build a docker container u slow down your container building by more then 100% all it does is create a docker file run a container and execute the provisioners. with a .sh file for example but that not save at all.

You should always build docker containers with a Dockerfile or by Hand.
