Install via Kolla Ansible


This installation guide is explaining about Tacker. Other components, such as nova or neutron, are not covered here.


This installation guide is just a bit old, and explained for Redhat distro.

Please refer to Install dependencies of kolla ansible installation1 to set up the docker environment that is used by kolla ansible.

To install via Kolla Ansible, the version of Kolla Ansible should be consistent with the target Tacker system. For example, stable/pike branch of Kolla Ansible should be used to install stable/pike branch of Tacker. Here the stable/pike branch version will be used to show how to install Tacker with Kolla Ansible.

Kolla can be used to install multiple nodes system, but Tacker server is not ready for multiple nodes deployment yet, so only an all-in-one Tacker is installed in this document.

Install Kolla Ansible

  1. Get the stable/pike version of kolla ansible:

    $ git clone https://github.com/openstack/kolla-ansible.git -b stable/pike
    $ cd kolla-ansible
    $ sudo yum install python-devel libffi-devel gcc openssl-devel libselinux-python
    $ sudo pip install -r requirements.txt
    $ sudo python setup.py install

    If the needed version has already been published at pypi site 'https://pypi.org/project/kolla-ansible', the command below can be used:

    $ sudo pip install "kolla-ansible==5.0.0"

Install Tacker

  1. Edit kolla ansible's configuration file /etc/kolla/globals.yml:

    kolla_install_type: "source"
    # openstack_release can be determined by version of kolla-ansible tool.
    # But if needed, it can be specified.
    #openstack_release: 5.0.0
    kolla_internal_vip_address: <one IP address of local nic interface>
    # The Public address used to communicate with OpenStack as set in the
    # public_url for the endpoints that will be created. This DNS name
    # should map to kolla_external_vip_address.
    #kolla_external_fqdn: "{{ kolla_external_vip_address }}"
    # define your own registry if needed
    #docker_registry: ""
    # If needed OpenStack kolla images are published, docker_namespace should be
    # kolla
    #docker_namespace: "kolla"
    docker_namespace: "gongysh"
    enable_glance: "no"
    enable_haproxy: "no"
    enable_keystone: "yes"
    enable_mariadb: "yes"
    enable_memcached: "yes"
    enable_neutron: "no"
    enable_nova: "no"
    enable_barbican: "yes"
    enable_mistral: "yes"
    enable_tacker: "yes"
    enable_heat: "no"
    enable_openvswitch: "no"
    enable_horizon: "yes"
    enable_horizon_tacker: "{{ enable_tacker | bool }}"


    To determine version of kolla-ansible, the following commandline can be used:

    $ python -c \
      "import pbr.version; print(pbr.version.VersionInfo('kolla-ansible'))"
  2. Run kolla-genpwd to generate system passwords:

    $ sudo cp etc/kolla/passwords.yml /etc/kolla/passwords.yml
    $ sudo kolla-genpwd


    If the pypi version is used to install kolla-ansible the skeleton passwords file maybe under /usr/share/kolla-ansible/etc_examples/kolla.

    With this command, /etc/kolla/passwords.yml will be populated with generated passwords.

  3. Run kolla ansible deploy to install tacker system:

    $ sudo kolla-ansible deploy
  4. Run kolla ansible post-deploy to generate tacker access environment file:

    $ sudo kolla-ansible post-deploy

    With this command, admin-openrc.sh will be generated at /etc/kolla/admin-openrc.sh.

  5. Check the related containers are started and running:

    Tacker system consists of some containers. Following is a sample output. The containers fluentd, cron and kolla_toolbox are from kolla, please see kolla ansible documentation for their usage. Others are from Tacker system components.

    $ sudo docker ps --format "table {{.ID}}\t{{.Image}}\t{{.Names}}"
    CONTAINER ID        IMAGE                                                    NAMES
