Source Install Ubuntu
~~~~~~~~~~~~~~~~~~~~~

This section describes how to install and configure the Skyline Console
service. Before you begin, you must have a ready OpenStack environment. At
least it includes ``keystone, glance, nova, neutron and skyline-apiserver service``.

For more information about skyline-apiserver installation, refer to the
`OpenStack Skyline APIServer Guide
<https://docs.openstack.org/skyline-apiserver/latest/install/source-install-ubuntu.html>`__.

Prerequisites
-------------

#. Install system dependencies

   .. code-block:: shell

      sudo apt update
      sudo apt install -y git python3-pip nginx make ssl-cert
      sudo apt-get install libgtk2.0-0 libgtk-3-0 libgbm-dev libnotify-dev libgconf-2-4 libnss3 libxss1 libasound2 libxtst6 xauth xvfb

#. Install nvm ( version control system for nodejs )

   .. code:: shell

      wget -P /root/ --tries=10 --retry-connrefused --waitretry=60 --no-dns-cache --no-cache  https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh
      bash /root/install.sh
      . /root/.nvm/nvm.sh

#. Install nodejs

   .. code:: shell

      nvm install --lts=Erbium
      nvm alias default lts/erbium
      nvm use default

#. Install yarn

   .. code:: shell

      npm install -g yarn

Install and configure components
--------------------------------

We will install the Skyline Console service from source code.

#. Git clone the repository from OpenDev (GitHub)

   .. code-block:: shell

      cd ${HOME}
      git clone https://opendev.org/openstack/skyline-console.git

   .. note::

      If you meet the following error, you need to run command ``sudo apt install -y ca-certificates``:

      `fatal: unable to access 'https://opendev.org/openstack/skyline-sonsole.git/': server
      certificate verification failed. CAfile: none CRLfile: none`

#. Install skyline-console

   .. code-block:: shell

      cd ${HOME}/skyline-console
      make package
      sudo pip3 install --force-reinstall dist/skyline_console-*.whl

#. Ensure that skyline folders have been created

   .. code-block:: shell

      sudo mkdir -p /etc/skyline /var/log/skyline

   .. note::
      Ensure that skyline.yaml file is available in /etc/skyline folder.
      For more information about skyline.yml, see
      `OpenStack Skyline Settings <https://docs.openstack.org/skyline-apiserver/latest/configuration/settings.html>`__.

#. Generate nginx configuration file

   .. code-block:: shell

      skyline-nginx-generator -o /etc/nginx/nginx.conf
      sudo sed -i "s/server .* fail_timeout=0;/server 0.0.0.0:28000 fail_timeout=0;/g" /etc/nginx/nginx.conf

   .. note::

      We need to change the ``upstream skyline`` value in ``/etc/nginx/nginx.conf`` to ``0.0.0.0:28000``.
      Default value is ``unix:/var/lib/skyline/skyline.sock``.

Finalize installation
---------------------

Start nginx service

.. code-block:: shell

   sudo systemctl start nginx.service
   sudo systemctl enable nginx.service
