Lightweight Linux workground with docker containers

# !/bin/bash -x

# run alpine linux in a temporary container, where we can play with any commands
# save as "docker-run-alpine.sh"
docker run -it --rm "$@" alpine:3.4 sh --login -i

Example of use:

# docker-run-alpine.sh --net=host                     (in host)
+ docker run -it --rm --net=host alpine:3.4 sh --login -i
#                                                     (in a temporary container)
