We want to be able to use container without the PID namespace. We basically want containers that can manage the host os, which I call Super Privileged Containers. We eventually would like to get to the point where the only namespace we use is the MNT namespace to bring the Apps userspace with it. By eliminating the PID namespace we can get better communication between the host and the clients and potentially tools like strace and gdb become easier to use. We also see tools like libvirtd running within a container telling systemd to place a VM in a particular cgroup, we need to have communications of the PID. I don't see us needing to share PID namespaces between containers, since this is really what docker exec does. So currently I see us just needing docker run --pid=host Docker-DCO-1.1-Signed-off-by: Dan Walsh <dwalsh@redhat.com> (github: rhatdan) Upstream-commit: 23feaaa240853c0e7f9817f8c2d272dd1c93ac3f Component: engine
Docker Documentation
This directory contains the Docker user manual in the Markdown format. Do not edit the man pages in the man1 directory. Instead, amend the Markdown (*.md) files.

Generating man pages from the Markdown files
The recommended approach for generating the man pages is via a Docker
container using the supplied Dockerfile to create an image with the correct
environment. This uses go-md2man, a pure Go Markdown to man page generator.
Building the md2man image
There is a Dockerfile provided in the docker/docs/man directory.
Using this Dockerfile, create a Docker image tagged docker/md2man:
docker build -t docker/md2man .
Utilizing the image
Once the image is built, run a container using the image with volumes:
docker run -v /<path-to-git-dir>/docker/docs/man:/docs:rw \
-w /docs -i docker/md2man /docs/md2man-all.sh
The md2man Docker container will process the Markdown files and generate
the man pages inside the docker/docs/man/man1 directory using
Docker volumes. For more information on Docker volumes see the man page for
docker run and also look at the article [Sharing Directories via Volumes]
(http://docs.docker.com/use/working_with_volumes/).
