Skyline API Server

English | 简体中文

Skyline is an OpenStack dashboard optimized by UI and UE, support OpenStack Train+. It has a modern technology stack and ecology, is easier for developers to maintain and operate by users, and has higher concurrency performance.

Skyline's mascot is the nine-color deer. The nine-color deer comes from Dunhuang mural "the nine-color king deer", whose moral is Buddhist cause-effect and gratefulness, which is consistent with 99cloud's philosophy of embracing and feedback community since its inception. We also hope Skyline can keep light, elegant and powerful as the nine-color deer, to provide a better dashboard for the openstack community and users.

Quick Start

Prerequisites

• An OpenStack environment that runs at least core components and can access OpenStack components through Keystone endpoints
• A Linux server with container engine (docker or podman) installed

Configure

1. Edit the /etc/skyline/skyline.yaml file in linux server

   You can refer to the sample file, and modify the following parameters according to the actual environment

   • database_url
   • keystone_url
   • default_region
   • interface_type
   • system_project_domain
   • system_project
   • system_user_domain
   • system_user_name
   • system_user_password

Deployment with Sqlite

1. Run the skyline_bootstrap container to bootstrap

   rm -rf /tmp/skyline && mkdir /tmp/skyline
   
   docker run -d --name skyline_bootstrap -e KOLLA_BOOTSTRAP="" -v /etc/skyline/skyline.yaml:/etc/skyline/skyline.yaml -v /tmp/skyline:/tmp --net=host 99cloud/skyline:latest
   
   # Check bootstrap is normal `exit 0`
   docker logs skyline_bootstrap
   

2. Run the skyline service after bootstrap is complete

   docker rm -f skyline_bootstrap
   
   docker run -d --name skyline --restart=always -v /etc/skyline/skyline.yaml:/etc/skyline/skyline.yaml -v /tmp/skyline:/tmp --net=host 99cloud/skyline:latest
   

Deployment with MariaDB

1. Connect to database of the OpenStack environment and create the skyline database

   $ mysql -u root -p
   MariaDB [(none)]> CREATE DATABASE IF NOT EXISTS skyline DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
   Query OK, 1 row affected (0.001 sec)
   

2. Grant proper access to the databases

   Replace SKYLINE_DBPASS with a suitable password.

   MariaDB [(none)]> GRANT ALL PRIVILEGES ON skyline.* TO 'skyline'@'localhost' IDENTIFIED BY 'SKYLINE_DBPASS';
   Query OK, 0 rows affected (0.001 sec)
   
   MariaDB [(none)]> GRANT ALL PRIVILEGES ON skyline.* TO 'skyline'@'%'  IDENTIFIED BY 'SKYLINE_DBPASS';
   Query OK, 0 rows affected (0.001 sec)
   

3. Create skyline service credentials

   # Source the admin credentials
   $ source admin-openrc
   
   # Create the 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 | 2020-08-08T08:08:08.123456       |
   +---------------------+----------------------------------+
   
   # Add the admin role to the skyline user:
   $ openstack role add --project service --user skyline admin
   

4. Run the skyline_bootstrap container to bootstrap

   docker run -d --name skyline_bootstrap -e KOLLA_BOOTSTRAP="" -v /etc/skyline/skyline.yaml:/etc/skyline/skyline.yaml --net=host 99cloud/skyline:latest
   
   # Check bootstrap is normal `exit 0`
   docker logs skyline_bootstrap
   

5. Run the skyline service after bootstrap is complete

   docker rm -f skyline_bootstrap
   
   docker run -d --name skyline --restart=always -v /etc/skyline/skyline.yaml:/etc/skyline/skyline.yaml --net=host 99cloud/skyline:latest
   

Test Access

You can now access the dashboard: https://<ip_address>:9999

Develop Skyline-apiserver

Support Linux & Mac OS (Recommend Linux OS) (Because uvloop & cython)

Dependent tools

Use the new feature Context Variables of python37 & uvloop(0.15.0+ requires python37). Considering that most systems do not support python37, we choose to support python38 at least.

• make >= 3.82
• python >= 3.8
• node >= 10.22.0 (Optional if you only develop with apiserver)
• yarn >= 1.22.4 (Optional if you only develop with apiserver)

Install & Run

1. Installing dependency packages

   tox -e venv
   

2. Set skyline.yaml config file

   cp etc/skyline.yaml.sample etc/skyline.yaml
   export OS_CONFIG_DIR=$(pwd)/etc
   

   Maybe you should change the params with your real environment as followed:

   - database_url
   - keystone_url
   - default_region
   - interface_type
   - system_project_domain
   - system_project
   - system_user_domain
   - system_user_name
   - system_user_password
   

   If you set such as sqlite:////tmp/skyline.db for database_url , just do as followed. If you set such as mysql://root:root@localhost:3306/skyline for database_url , you should refer to steps 1 and 2 of the chapter Deployment with MariaDB at first.

3. Init skyline database

   source .tox/venv/bin/activate
   make db_sync
   deactivate
   

4. Run skyline-apiserver

   $ source .tox/venv/bin/activate
   $ uvicorn --reload --reload-dir skyline_apiserver --port 28000 --log-level debug skyline_apiserver.main:app
   
   INFO:     Uvicorn running on http://127.0.0.1:28000 (Press CTRL+C to quit)
   INFO:     Started reloader process [154033] using statreload
   INFO:     Started server process [154037]
   INFO:     Waiting for application startup.
   INFO:     Application startup complete.
   

   You can now access the online API documentation: http://127.0.0.1:28000/docs.

   Or, you can launch debugger with .vscode/lauch.json with vscode.

5. Build Image
