$ cd alpine && docker build -t blacklabelops/alpine .
$ docker run -it --rm blacklabelops/alpine bash
$ cd centos && docker build -t blacklabelops/centos .
$ docker run -it --rm blacklabelops/centos bash
$ cd ubuntu && docker build -t blacklabelops/ubuntu .
$ docker run -it --rm blacklabelops/ubuntu bash
