Stan Lagun 8738324d9c Restores SIGPIPE on script processes 
There is an issue https://bugs.python.org/issue1652
in Python 2.7 which was resolved in Py3.

By default Python sets SIGPIPE to SIG_IGN on startup, because
it prefers to check every write and raise an IOError exception rather
than taking SIGPIPE. This is all well and good for Python itself.
However, non-Python Unix subprocesses generally expect to have
SIGPIPE set to the default action, since that's what will happen if
they're started from a normal shell.

As a result scripts with piping that is terminated in reverse chain
order are never exit.

Murano Agent

Murano Agent is a VM-side guest agent that accepts commands from Murano engine and executes them.

Image building using DiskImage-Builder

Folder, named contrib/elements contains diskimage-builder elements to build an image which contains the Murano Agent required to use Murano.

Ubuntu based image containing the agent can be built and uploaded to Glance with the following commands:

$ git clone https://git.openstack.org/openstack/diskimage-builder.git
$ git clone https://git.openstack.org/openstack/murano-agent.git
$ export ELEMENTS_PATH=murano-agent/contrib/elements
$ diskimage-builder/bin/disk-image-create vm ubuntu \
  murano-agent -o ubuntu-murano-agent.qcow2
$ glance image-create --disk-format qcow2 --container-format bare \
  --name ubuntu-murano --file ubuntu-murano.qcow2 \
  --property murano_image_info='{"title": "Ubuntu for Murano", "type": "linux"}'
