：ARC overview

Background information

The previous version of Alibaba Cloud CLI does not support structured parameters and is not easy to use. ARC is a new version of Alibaba Cloud CLI and designed for resourcification. It supports interactive input to improve user experience when you enter parameters. For more information, see alibabacloud-resourcify-cli and Releases.

Install ARC

You must install ARC before you can use it. Perform the following steps to install ARC:

1. Install the Node.js environment.

   • For macOS

     You can use one of the following methods to install the Node.js environment:

     • Use the source code package.

       Download the PKG file from the Node.js site.

     • Use Homebrew.

       Run the brew install node command to install the Node.js environment.

   • For Windows

     Download the MSI file from the Node.js site.

2. Run the following command to install ARC:

   npm i @alicloud/arc -g

Use ARC

This section describes how to use ARC. In the following examples, ACK cluster resources are deployed to demonstrate how to use ARC.

1. Set the AccessKey pair

   You must set the AccessKey pair and region before you can use ARC.

   • Method 1: Set the AccessKey pair, region, and language in interactive mode.

     Run the following command to set the preceding information:

     arc-tool config

     Output:

     ? The AccessKey ID.
     access-key-id access_key_id
     ? The AccessKey secret.
     access-key-secret access_key_secret
     ? Select relevant options or end the configuration. region
     ? The region.
     region cn-beijing
     ? Select relevant options or end the configuration. language
     ? The language used by the CLI.
     language en
     ? Specify whether to display and run commands.
     arc-tool config  --access-key-id access_key_id --access-key-secret access_key_secret --region cn-beijing --language en

   • Method 2: Run commands to set the AccessKey pair, region, and language.

     Sample commands:

     arc-tool config set access_key_id <value>
     arc-tool config set access_key_secret <value>
     arc-tool config set region <region_id>
     arc-tool config set <en|zh>

2. Creates a cluster.

   • Method 1: Create a cluster in interactive mode.

     Run the following command to use the -i option to enable the interactive mode:

     arc-cs cluster create-managed -i

     Output:

     ? The following options are mutually exclusive. Select only one of them.  login-password
     ? Set the SSH logon password. The password must be 8 to 30 characters in length, and must contain at least three of the following character types: uppercase letters, lowercase letters, digits, and special characters. 
     login-password Hello****
     ? Specify a name for the cluster. The name can contain letters, digits, and hyphens (-).
