Add a --pid=host feature to expose the host PID space to the container 

Docker 1.5.0+ introduces a --pid=host feature which allows sharing of PID
namespaces between baremetal and containers.  This is useful for atomic
upgrades, atomic rollbacks, and monitoring.

For more details of a real-life use case, check out:

pid: "host"

Sets the PID mode to the host PID mode. This turns on sharing between
container and the host operating system the PID address space. Containers
launched with this flag will be able to access and manipulate other
containers in the bare-metal machine's namespace and vise-versa.
