Docker Install Ubuntu

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

Note

You have install the docker service on the host machine. You can follow the docker installation.

Prerequisites

Before you install and configure Skyline service, you must create a database.

1. To create the database, complete these steps:

   1. Use the database access client to connect to the database server as the root user:

      # mysql
      

   2. Create the skyline database:

      MariaDB [(none)]> CREATE DATABASE skyline DEFAULT CHARACTER SET \
        utf8 DEFAULT COLLATE utf8_general_ci;
      

   3. Grant proper access to the skyline database:

      MariaDB [(none)]> GRANT ALL PRIVILEGES ON skyline.* TO 'skyline'@'localhost' \
        IDENTIFIED BY 'SKYLINE_DBPASS';
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON skyline.* TO 'skyline'@'%' \
        IDENTIFIED BY 'SKYLINE_DBPASS';
      

      Replace SKYLINE_DBPASS with a suitable password.

   4. Exit the database access client.

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

   $ . admin-openrc
   

3. To create the service credentials, complete these steps:

   1. Create a skyline user:

      $ openstack user create --domain default --password-prompt skyline
      
      User Password:
      Repeat User Password:
      +---------------------+----------------------------------+
      | Field               | Value                            |
      +---------------------+----------------------------------+
      | domain_id           | default                          |
      | enabled             | True                             |
      | id                  | 1qaz2wsx3edc4rfv5tgb6yhn7ujm8ikl |
      | name                | skyline                          |
      | options             | {}                               |
      | password_expires_at | None                             |
      +---------------------+----------------------------------+
      

   2. Add the admin role to the skyline user:

      $ openstack role add --project service --user skyline admin
      

      Note

      This command provides no output.

Install and configure components

We will install Skyline service from docker image.

1. Pull Skyline service image from Docker Hub:

   $ sudo docker pull 99cloud/skyline:latest
   

2. Ensure that some folders of skyline have been created

   $ sudo mkdir -p /etc/skyline /var/log/skyline /var/lib/skyline /var/log/nginx
   

3. Configure /etc/skyline/skyline.yaml file

   Note

   Change the related configuration in /etc/skyline/skyline.yaml. Detailed introduction of the configuration can be found in OpenStack Skyline Settings.

   default:
     database_url: mysql://skyline:SKYLINE_DBPASS@DB_SERVER:3306/skyline
     debug: true
     log_dir: /var/log
   openstack:
     keystone_url: http://KEYSTONE_SERVER:5000/v3/
     system_user_password: SKYLINE_SERVICE_PASSWORD
   

   Replace SKYLINE_DBPASS, DB_SERVER, KEYSTONE_SERVER and SKYLINE_SERVICE_PASSWORD with a correct value.

Finalize installation

1. Run bootstrap server

   $ sudo docker run -d --name skyline_bootstrap \
     -e KOLLA_BOOTSTRAP="" \
     -v /etc/skyline/skyline.yaml:/etc/skyline/skyline.yaml \
     -v /var/log:/var/log \
     --net=host 99cloud/skyline:latest
   

   If you see the following message, it means that the bootstrap server is successful:
   
   + echo '/usr/local/bin/gunicorn -c /etc/skyline/gunicorn.py skyline_apiserver.main:app'
   + mapfile -t CMD
   ++ xargs -n 1
   ++ tail /run_command
   + [[ -n 0 ]]
   + cd /skyline-apiserver/
   + make db_sync
   alembic -c skyline_apiserver/db/alembic/alembic.ini upgrade head
   2022-08-19 07:49:16.004 | INFO     | alembic.runtime.migration:__init__:204 - Context impl MySQLImpl.
   2022-08-19 07:49:16.005 | INFO     | alembic.runtime.migration:__init__:207 - Will assume non-transactional DDL.
   + exit 0
   

2. Cleanup bootstrap server

   $ sudo docker rm -f skyline_bootstrap
   

3. Run skyline

   $ sudo docker run -d --name skyline --restart=always \
     -v /etc/skyline/skyline.yaml:/etc/skyline/skyline.yaml \
     -v /var/log:/var/log \
     --net=host 99cloud/skyline:latest
   

   Note

   The skyline image is both include skyline-apiserver and skyline-console. And you can visit the skyline UI https://xxxxx:9999.
