Clear Containers in Zun
|
|
=======================
|
|
|
|
Zun now supports running Clear Containers with regular Docker containers.
|
|
Clear containers run containers as very lightweight virtual machines
|
|
which boot up really fast and has low memory footprints. It provides
|
|
security to the containers with an isolated environment. You can read
|
|
more about Clear Containers `here <https://github.com/clearcontainers/runtime/wiki>`_.
|
|
|
|

|
==========================
|
|
It is possible to run Clear Containers with Zun. Follow the
|
|
:doc:`/contributor/quickstart` to download DevStack, Zun code and copy the
|
|
local.conf file. Now perform the following steps to install Clear Containers
|
|
with DevStack::
|
|
|
|

|
|
