# DinD: a wrapper script which allows docker to be run inside a docker container.
|
|
# Original version by Jerome Petazzoni <jerome@docker.com>
|
|
# See the blog post: https://blog.docker.com/2013/09/docker-can-now-run-within-docker/
|
|
#
|
|
# This script should be executed inside a docker container in privileged mode
|
|
# ('docker run --privileged', introduced in docker 0.6).
|
|
|
|
# Usage: dind CMD [ARG...]
|
|
|
|
# apparmor sucks and Docker needs to know that it's in a container (c) @tianon
