===================
Manual Installation
===================

This document describes how to install and run Tacker manually on the
controller node.

Pre-requisites
==============

1). Ensure that OpenStack components Keystone, Glance, Nova, Neutron, Heat and
Horizon are installed. Refer http://docs.openstack.org/ for installation of
OpenStack on different Operating Systems.

2). Create client environment scripts "admin-openrc.sh" and "demo-openrc.sh"
for the admin and demo projects. Sample instructions for Ubuntu can be found
at link below:
http://docs.openstack.org/liberty/install-guide-ubuntu/keystone-openrc.html#creating-the-scripts

3).Ensure that the below required packages are installed on the system.

.. code-block:: console

    sudo apt-get install python-pip git

..

4). Ensure entry for extensions drivers in ml2_conf.ini. Restart neutron
services after the below entry has been added.

.. code-block:: console

    [ml2]
    extension_drivers = port_security

..

5). Modify heat's policy.json file under /etc/heat/policy.json file to allow
 users in non-admin projects with 'admin' roles to create flavors.

.. code-block:: ini

   "resource_types:OS::Nova::Flavor": "role:admin"
..

Installing Tacker server
========================

1). Create MySQL database and user.

.. code-block:: console

    mysql -uroot -p
    CREATE DATABASE tacker;
    GRANT ALL PRIVILEGES ON tacker.* TO 'tacker'@'localhost' \
        IDENTIFIED BY '<TACKERDB_PASSWORD>';
    GRANT ALL PRIVILEGES ON tacker.* TO 'tacker'@'%' \
        IDENTIFIED BY '<TACKERDB_PASSWORD>';
    exit;
..

2). Create users, roles and endpoints.

a). Source the admin credentials to gain access to admin-only CLI commands:

.. code-block:: console

    source admin-openrc.sh
..

b). Create tacker user with admin privileges.

.. note::

        Project_name can be "service" or "services" depending on your
        OpenStack distribution.
..

.. code-block:: console

    openstack user create --password <PASSWORD> tacker
    openstack role add --project services --user tacker admin
..

c). Create tacker service.

.. code-block:: console

    openstack service create --name tacker \
        --description "Tacker Project" nfv-orchestration
..

d). Provide an endpoint to tacker service.

.. code-block:: console

    openstack endpoint create --region RegionOne \
        --publicurl 'http://<TACKER_NODE_IP>:9890/' \
        --adminurl 'http://<TACKER_NODE_IP>:9890/' \
        --internalurl 'http://<TACKER_NODE_IP>:9890/' <SERVICE-ID>
..


3). Clone tacker repository.

.. code-block:: console

    git clone https://github.com/openstack/tacker
..

4). Install all requirements.

.. code-block:: console

    cd tacker
    sudo  pip install -r requirements.txt

..

.. note::

        If OpenStack components mentioned in pre-requisites section have been
        installed, the below command would be sufficient.

.. code-block:: console

    cd tacker
    sudo  pip install tosca-parser

..


5). Install tacker.

.. code-block:: console

    sudo python setup.py install
..

..

6). Create 'tacker' directory in '/var/log'.

.. note::

        The above referenced path '/var/log' is for Ubuntu and may be
        different for other Operating Systems.

.. code-block:: console

    sudo mkdir /var/log/tacker

..

7). Generate the tacker.conf.sample using tools/generate_config_file_sample.sh
    or 'tox -e config-gen' command and rename it to tacker.conf. Then edit it
    to ensure the below entries:

.. note::

        In Ubuntu 14.04, the tacker.conf is located at /usr/local/etc/tacker/
        and below ini sample is for Ubuntu and directory paths referred in
        ini may be different for other Operating Systems.

.. note::

        Project_name can be "service" or "services" depending on your
        OpenStack distribution in the keystone_authtoken section.
..
.. code-block:: ini

    [DEFAULT]
    auth_strategy = keystone
    policy_file = /usr/local/etc/tacker/policy.json
    debug = True
    use_syslog = False
    state_path = /var/lib/tacker
    ...
    [keystone_authtoken]
    project_name = service
    password = <TACKER_SERVICE_USER_PASSWORD>
    auth_url = http://<KEYSTONE_IP>:35357
    #identity_uri = http://<KEYSTONE_IP>:5000
    auth_uri = http://<KEYSTONE_IP>:5000
    ...
    [agent]
    root_helper = sudo /usr/local/bin/tacker-rootwrap /usr/local/etc/tacker/rootwrap.conf
    ...
    [DATABASE]
    connection = mysql://tacker:<TACKERDB_PASSWORD>@<MYSQL_IP>:3306/tacker?charset=utf8
    ...
    [tacker_heat]
    heat_uri = http://<HEAT_IP>:8004/v1
..

8). Populate Tacker database:

.. note::

       The below command is for Ubuntu Operating System.

.. code-block:: console

    /usr/local/bin/tacker-db-manage --config-file /etc/tacker/tacker.conf upgrade head

..


Install Tacker client
=====================

1). Clone tacker-client repository.

.. code-block:: console

    cd ~/
    git clone https://github.com/openstack/python-tackerclient
..

2). Install tacker-client.

.. code-block:: console

    cd python-tackerclient
    sudo python setup.py install
..

Install Tacker horizon
======================


1). Clone tacker-horizon repository.

.. code-block:: console

    cd ~/
    git clone https://github.com/openstack/tacker-horizon
..

2). Install horizon module.

.. code-block:: console

    cd tacker-horizon
    sudo python setup.py install
..

3). Enable tacker horizon in dashboard.

.. note::

        The below destination path referred is for Ubuntu 14.04 and may
        change for other Operating Systems.

.. code-block:: console

    sudo cp openstack_dashboard_extensions/* \
        /usr/share/openstack-dashboard/openstack_dashboard/enabled/
..

4). Restart Apache server.

.. code-block:: console

    sudo service apache2 restart
..

Starting Tacker server
======================

1).Open a new console and launch tacker-server. A separate terminal is
required because the console will be locked by a running process.

.. note::
        Ensure that ml2_conf.ini as per Step 4 from the pre-requisites
        section has been configured.

.. code-block:: console

    sudo python /usr/local/bin/tacker-server \
        --config-file /usr/local/etc/tacker/tacker.conf \
        --log-file /var/log/tacker/tacker.log
..

Registering default VIM
=======================
Register the VIM that will be used as a default VIM for VNF deployments.
This will be required when the optional argument --vim-id is not provided by
the user during vnf-create.

.. code-block:: console

    tacker vim-register --is-default --config-file config.yaml \
    --description <Default VIM description> <Default VIM Name>

config.yaml will contain VIM specific parameters as below:

.. code-block:: ini

    auth_url: http://<keystone_public_endpoint_url>:5000
    username: <username>
    password: <password>
    project_name: <project_name>

Add following parameters to config.yaml if VIM is using keystone v3:

.. code-block:: ini

    project_domain_name: <domain>
    user_domain_name: <domain>

.. note::
   Here username must point to the user having 'admin' and 'advsvc' role on the
   project that will be used for deploying VNFs.
3). Restart tacker server.
