Manual Installation

This document describes how to install and run Tacker manually.

Note

This installation guide contents are specific to Ubuntu distro. Some steps in this installation guide may be invalid for other distributions. For example, you should replace /usr/local/bin/ with /usr/bin/ on CentOS.

Pre-requisites

1. Install required components.

   Ensure that all required OpenStack components i.e. Keystone, Barbican and Horizon are installed. Refer the list below for installation of these OpenStack components on different Operating Systems.

   • https://docs.openstack.org/keystone/latest/install/index.html

   • https://docs.openstack.org/barbican/latest/install/install.html

   • https://docs.openstack.org/horizon/latest/install/index.html

2. Create admin-openrc.sh for environment variables.

   export OS_PROJECT_DOMAIN_NAME=Default
   export OS_USER_DOMAIN_NAME=Default
   export OS_PROJECT_NAME=admin
   export OS_TENANT_NAME=admin
   export OS_USERNAME=admin
   export OS_PASSWORD=KTskN5eUMTpeHLKorRcZBBbH0AM96wdvgQhwENxY
   export OS_AUTH_URL=http://localhost:5000/identity
   export OS_INTERFACE=internal
   export OS_IDENTITY_API_VERSION=3
   export OS_REGION_NAME=RegionOne
   

Installing Tacker Server

Note

Make sure to replace the <branch_name> in command examples with specific branch name, such as stable/2023.1.

Note

From Tacker Antelope, PostgreSQL is available as a Tacker DB. If you would like to use PostgreSQL, please see Install via Devstack document.

1. Create MySQL database and user.

   $ mysql -uroot -p
   

   Create database tacker and grant privileges to tacker user with password <TACKERDB_PASSWORD> on all tables.

   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 OpenStack user, role and endpoint.

   1. Set admin credentials to gain access to admin-only CLI commands.

      $ . admin-openrc.sh
      

   2. Create tacker user with admin privileges.

      $ openstack user create --domain default --password <PASSWORD> tacker
      $ openstack role add --project service --user tacker admin
      

      Note

      Project name can be service or services depending on your OpenStack distribution.

   3. Create tacker service.

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

   4. Provide an endpoint to tacker service.

      For keystone v3:

      $ openstack endpoint create --region RegionOne nfv-orchestration \
                 public http://<TACKER_NODE_IP>:9890/
      $ openstack endpoint create --region RegionOne nfv-orchestration \
                 internal http://<TACKER_NODE_IP>:9890/
      $ openstack endpoint create --region RegionOne nfv-orchestration \
                 admin http://<TACKER_NODE_IP>:9890/
      

      For keystone v2:

      $ 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.

   You can use -b for specific release, optionally.

   $ cd ${HOME}
   $ git clone https://opendev.org/openstack/tacker.git -b <branch_name>
   

4. Install required packages and tacker itself.

   $ cd ${HOME}/tacker
   $ sudo pip3 install -r requirements.txt
   $ sudo python3 setup.py install
   

5. Create directories for tacker.

   Directories for storing logs, vnf packages and csar files are required.

   $ sudo mkdir -p /var/log/tacker \
       /var/lib/tacker/vnfpackages \
       /var/lib/tacker/csar_files
   

   Note

   In case of multi node deployment, we recommend to configure /var/lib/tacker/csar_files on a shared storage.

6. Generate the tacker.conf.sample using tools/generate_config_file_sample.sh or tox -e config-gen command. Rename the tacker.conf.sample file at etc/tacker/ to tacker.conf. Then edit it to ensure the below entries:

   Note

   Ignore any warnings generated while using the “generate_config_file_sample.sh”.

   Note

   project_name can be “service” or “services” depending on your OpenStack distribution in the keystone_authtoken section.

   Note

   The path of tacker-rootwrap varies according to the operating system, e.g. it is /usr/bin/tacker-rootwrap for CentOS, therefore the configuration for [agent] should be like:

   [agent]
   root_helper = sudo /usr/bin/tacker-rootwrap /etc/tacker/rootwrap.conf
   

   [DEFAULT]
   auth_strategy = keystone
   policy_file = /etc/tacker/policy.yaml
   debug = True
   use_syslog = False
   bind_host = <TACKER_NODE_IP>
   bind_port = 9890
   service_plugins = nfvo,vnfm
   
   state_path = /var/lib/tacker
   transport_url = rabbit://<RABBIT_USERID>:<RABBIT_PASSWORD>@<TACKER_NODE_IP>:5672/
   ...
   
   [nfvo_vim]
   vim_drivers = openstack
   
   [keystone_authtoken]
   memcached_servers = <TACKER_NODE_IP>:11211
   region_name = RegionOne
   auth_type = password
   project_domain_name = <DOMAIN_NAME>
   user_domain_name = <DOMAIN_NAME>
   username = <TACKER_USER_NAME>
   project_name = service
   password = <TACKER_SERVICE_USER_PASSWORD>
   auth_url = http://<KEYSTONE_IP>:5000
   www_authenticate_uri = http://<KEYSTONE_IP>:5000
   ...
   
   [agent]
   root_helper = sudo /usr/local/bin/tacker-rootwrap /etc/tacker/rootwrap.conf
   ...
   
   [database]
   connection = mysql+pymysql://tacker:<TACKERDB_PASSWORD>@<MYSQL_IP>:3306/tacker?charset=utf8
   ...
   
   [tacker]
   monitor_driver = ping,http_ping
   

7. Copy the tacker.conf to /etc/tacker/ directory.

   $ sudo cp etc/tacker/tacker.conf /etc/tacker/
   

8. Populate Tacker database.

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

9. To make tacker be controlled from systemd, copy tacker.service and tacker-conductor.service file to /etc/systemd/system/ directory, and restart systemctl daemon.

   $ sudo cp etc/systemd/system/tacker.service /etc/systemd/system/
   $ sudo cp etc/systemd/system/tacker-conductor.service /etc/systemd/system/
   $ sudo systemctl daemon-reload
   

Install Tacker Client

1. Clone tacker-client repository.

   You can use -b for specific release, optionally.

   $ cd ~/
   $ git clone https://opendev.org/openstack/python-tackerclient.git -b <branch_name>
   

2. Install tacker-client.

   $ cd ${HOME}/python-tackerclient
   $ sudo python3 setup.py install
   

Install Tacker horizon

1. Clone tacker-horizon repository.

   You can use -b for specific release, optionally.

   $ cd ~/
   $ git clone https://opendev.org/openstack/tacker-horizon.git -b <branch_name>
   

2. Install horizon module.

   $ cd ${HOME}/tacker-horizon
   $ sudo python3 setup.py install
   

3. Enable tacker horizon in dashboard.

   $ sudo cp tacker_horizon/enabled/* \
       /usr/share/openstack-dashboard/openstack_dashboard/enabled/
   

4. Restart Apache server.

   $ sudo service apache2 restart
   

Starting Tacker server

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

$ sudo systemctl start tacker.service

Starting Tacker conductor

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

$ sudo systemctl start tacker-conductor.service
