# Integrating with Kolla
This guide describes how to integrate with Kolla. The main integration path is
via docker-compose using docker-compose YML files. Each container set has
a common YML and associated `openstack.env`. The `openstack.env` file
describes the command line environment to pass to the docker-compose yml files.
## Why integrate with Kolla?
Integrating with Kolla takes a hard part of managing an OpenStack system,
specifically managing the container images, and places the burden on a third
party project. We strive to do an excellent job of providing world-class
OpenStack containers at least as a reference architecture, and possibly as what
may be desirable to deploy into live production.
## Docker Command Line Arguments
Every container set YML file includes the necessary docker CLI operations
needed to launch the container in a tidy YML file. Instead of guessing which
set of command line operations are needed per container, the docker-compose
YML file can be used directly and will pass the appropriate command line
values to the container on container start.
The parameterized docker features used by kolla are:
* --pid=host
* --net=host
* -v host:container
* --privileged
These parameterized features are not exposed to the user. Instead they are
executed via docker-compose.
## Environment Variables
Rather then document which individual containers require specific configuration
variables, Kolla integration requires passing all configuration variables to
all containers. This allows a simple method of ensuring every type of node
(controller, storage, compute) receives the same configuration.

## Launching a container set
Pick out a simple container set and launch it as follows:
$ docker-compose -f compose/rabbitmq.yml up -d
The third party deployment engine should launch the appropriate containers for
the appropriate nodes. Note the `rabbitmq.yml` used in the example above
expects an `openstack.env` file present in the current working directory. This
file will be passed as environment data to the container and configure the
container appropriately.
# Conclusion
Integrating with Kolla is as sample as creating an `openstack.env` file, having
a deployment tool write the `openstack.env` file and .yml files to the nodes are
targeted for deployment, and running docker-compose as described in the above
documentation.
