Software Installation and Deployment
------------------------------------
.. <DESCRIBE THE FULL PROCEDURES FOR THE INSTALLATION OF THE O-RAN COMPONENT INSTALLATION AND DEPLOYMENT>

Tacker Installation
~~~~~~~~~~~~~~~~~~~
This section describes the installation of the Tacker installation on the reference hardware.

* Installation Using Install Script

  The install script can be retrieved from smo-o2 repository::

      $ git clone https://gerrit.o-ran-sc.org/r/smo/o2

  Usage::

      $ cd o2/tacker/scripts
      $ ./install.sh <HOST_IP>

      <HOST_IP>: You should set host IP for API endpoint of Tacker.

  This script installs the Tacker via Devstack (Standalone mode).
  It uses the latest repositories (Devstack and Tacker).

  If you want to use other version, you have to change the URL.

  e.g.::

      git clone https://opendev.org/openstack-dev/devstack -b stable/yoga
      wget https://opendev.org/openstack/tacker/raw/branch/stable/yoga/devstack/local.conf.standalone
