Install via Openstack-helm
==========================

Overview
--------

This document specifies procedure for installing tacker service with
OpenStack-helm. The goal of OpenStack-helm is to provide a collection
of Helm charts that simply, resiliently, and flexibly deploy OpenStack
and related services on Kubernetes.

Pre-Requisites for Tacker installation with openstack-helm
----------------------------------------------------------

Pre-requisite for tacker installation are below:

#. Clone OpenStack-helm and openstack-helm-infra code in home directory.

   .. code-block:: console

       $ git clone https://opendev.org/openstack/openstack-helm.git
       $ git clone https://opendev.org/openstack/openstack-helm-infra.git
       $ cd openstack-helm

#. Setup Kubernetes.

   Please refer to install dependencies of Kubernetes Installation [1]_.

#. Create namespace with name openstack and provide label to node.

   .. code-block:: console

       $ kubectl create ns openstack
       $ kubectl label node <node-name> openstack-control-plane=enabled

#. Setup OpenStack.

   Please refer to install following dependencies of OpenStack Installation:

   * Deploy ingress controller [2]_.

   * Deploy OpenStack backend [3]_.

   * Deploy OpenStack [4]_.

   Here you can see how to install OpenStack and it's dependencies using
   openstack-helm.

.. note::

  Barbican must be installed. Although not documented in Deploy OpenStack [4]_,
  you must install Barbican using similar procedure. Execute the following
  script to install Barbican.

  .. code-block:: console

      $ cd ~/openstack-helm
      $ ./tools/deployment/component/barbican/barbican.sh

Install Tacker
--------------

#. Tacker installation with OpenStack-helm will use script tacker.sh.

   Use script tacker.sh to install tacker.

   .. code-block:: console

       $ cd ~/openstack-helm
       $ ./tools/deployment/component/tacker/tacker.sh

#. Validate tacker-conductor and tacker-server pods are running and
   deployment status of helm release is deployed.

   .. code-block:: console

       $ kubectl get pods -A | grep tacker
