How to create a service using ComputeNest CLI - Compute Nest

This topic describes how to quickly create a Compute Nest service based on a built-in template using ComputeNest CLI.

Prerequisites

Python 3.7 or later is available. If you have not installed Python, see Deploy Python environment.
Create an AccessKey dedicated for ComputeNest CLI access. For more information, see Create an AccessKey for a RAM user.

Install ComputeNest CLI

pip install computenest-cli

Create a service using an official template

View officially maintained projects.
```
computenest-cli list-projects
```

Initialize the project and specify the project folder. This section uses SpringBoot Basic Edition-Package Deployment as an example.

cd project  # Specify the project directory
computenest-cli init-project --project_name=springboot-ecs-package-demo 
cd springboot-ecs-package-demo

Log on to Compute Nest using your AccessKey.

computenest-cli login --access_key_id=<yourAccessKeyID> --access_key_secret=<yourAccessKeySecret>

Create a service.

computenest-cli import --service_name=springboot-ecs-package-demo-test01

After the service is created, you can log on to the Compute Nest - My Services page to view the detailed information of the created service.

How it works

To create a service using ComputeNest CLI, the project must include Compute Nest service configuration files. Taking the SpringBoot demo as an example, the Compute Nest configuration file structure is as follows:

.
└── .computenest                    - Stores Compute Nest service build configuration
    ├── README.md                   - Service description and service build instructions
    ├── docs                        - Service documentation related files
    │   └── index.md
    ├── service_test                - Service test folder
    ├── resources                   - Service resource files
    │   ├── icons
    │   │   └── service_logo.png    - Service logo
    │   └── artifact_resources      - Deployment artifact related resource files
    │       └── file                - File deployment artifact directory
    │           └── package.tgz     - SpringBoot installation package
    ├── ros_templates               - Service ROS templates, can have multiple
    │   └── template.yaml           - Example ROS template
    ├── config.yaml                 - Service configuration file

config.yaml defines the configuration information of the Compute Nest service.
The ros_templates directory contains ROS templates. ROS is an official Alibaba Cloud Infrastructure as Code (IaC) language that allows you to define resource architecture.
The resources directory defines service resources, including service logo, deployment artifact resources, and more. For example, software packages can be stored in this directory.
The service_test directory defines service tests, which can include test cases.
