===============================
Welcome to Zun's documentation!
===============================

What is Zun?
=============

Zun is an OpenStack Container service. It aims to provide an API service for
running application containers without the need to manage servers or clusters.

It requires the following additional OpenStack services for basic function:

* `Keystone <https://docs.openstack.org/keystone/latest/>`__
* `Neutron <https://docs.openstack.org/neutron/latest/>`__
* `Kuryr-libnetwork <https://docs.openstack.org/kuryr-libnetwork/latest/>`__

It can also integrate with other services to include:

* `Cinder <https://docs.openstack.org/cinder/latest/>`__
* `Heat <https://docs.openstack.org/heat/latest/>`__
* `Glance <https://docs.openstack.org/glance/latest/>`__

For End Users
=============

As an end user of Zun, you'll use Zun to create and manage containerized
workload with either tools or the API directly.
All end user (and some administrative) features of Zun are exposed via a REST
API, which can be consumed directly. The following resources will help you get
started with consuming the API directly.

* `API Reference <https://docs.openstack.org/api-ref/application-container/>`_

Alternatively, end users can consume the REST API via various tools or SDKs.
These tools are collected below.

* `Horizon
  <https://docs.openstack.org/zun-ui/latest/>`_: The
  official web UI for the OpenStack Project.
* `OpenStack Client
  <https://docs.openstack.org/python-openstackclient/latest/>`_: The official
  CLI for OpenStack Projects.
* `Zun Client
  <https://docs.openstack.org/python-zunclient/latest/>`_: The Python client
  for consuming the Zun's API.
