Configure

For detailed configuration instructions, please visit the official website Configuration Alibaba Cloud CLI.

Before using Alibaba Cloud CLI to invoke the services, you need to configure the credential information, region, language, etc.

You can run the aliyun configure command for quick configuration.

$ aliyun configure
Configuring profile 'default' ...
Aliyun Access Key ID [None]: <Your AccessKey ID>
Aliyun Access Key Secret [None]: <Your AccessKey Secret>
Default Region Id [None]: cn-hangzhou
Default output format [json]: json
Default Language [zh]: zh

Configure authentication methods

You can specify the authentication method to use by using the configure command with the --mode <authenticationMethod> option.

The following are supported authentication methods:

Authentication methods Description
AK Use AccessKey ID and Secret to access Alibaba Cloud services
StsToken Use STS token to access Alibaba Cloud services
RamRoleArn Use the AssumeRole to access Alibaba Cloud services
EcsRamRole Use the EcsRamRole to access ECS resources

Use an external program to get credentials

You can use --mode External to specify to obtain credential data through an external program, and CLI will execute the program command and return it as a credential to initiate the call.

Agreement:

  1. The output location of the external program is standard output.
  2. The output format is json string.
  3. The output contains the key fields required by the CLI and credential fields

Key field:

  • mode: Specify the type of credentials returned

Example of the return of each credential type:

  • AK
{
  "mode": "AK",
  "access_key_id": "accessKeyId",
  "access_key_secret": "accessKeySecret"
}
  • StsToken
{
  "mode": "StsToken",
  "access_key_id": "accessKeyId",
  "access_key_secret": "accessKeySecret",
  "sts_token": "stsToken"
}
  • RamRoleArn
{
  "mode": "RamRoleArn",
  "access_key_id": "accessKeyId",
  "access_key_secret": "accessKeySecret",
  "ram_role_arn": "ramRoleArn",
  "ram_session_name": "ramSessionName"
}
  • EcsRamRole
{
  "mode": "EcsRamRole",
  "ram_role_name": "ramRoleName"
}

Example:

$ aliyun configure --mode External --profile externalTest
Configuring profile 'externalTest' in 'External' authenticate mode...
Process Command []: <getCredential ak>
Default Region Id []: cn-hangzhou
Default Output Format [json]: json (Only support json)
Default Language [zh|en] en: 
Saving profile[externalTest] ...Done.

Use chainable RamRoleArn

You can use --mode ChainableRamRoleArn to combile a source profile and RAM role ARN flow. The following example get intermediate credentials from source profile cli-test, then use it to call AssumeRole for get final credentials.

{
  "profiles": [
    {
      "name": "chain",
      "mode": "ChainableRamRoleArn",
      "ram_role_arn": "acs:ram::<Account ID>:role/<Role Name>",
      "ram_session_name": "session",
      "source_profile": "cli-test"
    },
    {
      "name": "cli-test",
      "mode": "AK",
      "access_key_id": "<Access Key ID>",
      "access_key_secret": "<Access Key Secret>"
    }
  ]
}

Use Credentials URI

You can use --mode CredentialsURI to get credentials from local/remote URI.

{
  "profiles": [
    {
      "name": "uri",
      "mode": "CredentialsURI",
      "credentials_uri": "http://localhost:6666/?user=jacksontian"
    }
  ]
}

The Credentials URI must be response with status code 200, and following body:

{
  "Code": "Success",
  "AccessKeyId": "<ak id>",
  "AccessKeySecret": "<ak secret>",
  "SecurityToken": "<security token>",
  "Expiration" "2006-01-02T15:04:05Z" // utc time
}

Otherwise, CLI treate as failure case.

Enable bash/zsh auto completion

  • Use aliyun auto-completion command to enable auto completion in zsh/bash
  • Use aliyun auto-completion --uninstall command to disable auto completion.

Use Alibaba Cloud CLI

Here is the basic usage guidelines. If you need a detailed manual, please visit Use Alibaba Cloud CLI

The Alibaba Cloud OpenAPI has two styles, RPC style and RESTful style. Most of the Alibaba Cloud products use the RPC style. The way of calling an API varies depending on the API style.

You can distinguish the API style from the following characteristics:

  • The API requiring the Action parameter is the RPC style, while the API requiring the PathPattern parameter is the RESTful style.
  • In general, the API style for a product is consistent.
  • Each API only supports one style. If an incorrect calling method is used, another API may be called or an error ApiNotFound is returned.

Call RPC APIs

The following statement shows how to call RPC APIs in the Alibaba Cloud CLI:

aliyun <product> <operation> --parameter1 value1 --parameter2 value2 ...

Examples:

aliyun rds DescribeDBInstances --PageSize 50
aliyun ecs DescribeRegions
aliyun rds DescribeDBInstanceAttribute --DBInstanceId xxxxxx

Call RESTful APIs

APIs of some products such as Container Service are RESTful style. The way to call RESTful APIs is different from RPC APIs.

The following examples show how to call RESTful APIs in the Alibaba Cloud CLI:

  • GET request:

    aliyun cs GET /clusters
  • POST request:

    aliyun cs POST /clusters --body "$(cat input.json)"
  • DELETE request:

    aliyun cs DELETE /clusters/ce2cdc26227e09c864d0ca0b2d5671a07

Get help information

Alibaba Cloud CLI integrates API descriptions for some products, you can get help by using the following commands:

  • aliyun help: get product list

  • aliyun help <product>: get the API information of a specific product

    For example, get help of ECS APIs: $ aliyun help ecs

  • $ aliyun help <product> <apiName>: get the detailed API information of a specific APU

    For example, get the help information of the CreateInstance API: aliyun help ecs CreateInstance

Use the --force option

Alibaba Cloud CLI integrates the product metadata of some products. It will validate API parameters when calling the API. If an API or a parameter that is not included in the metadata is used, an error unknown api or unknown parameter will be returned. You can use the --force option to skip the validation and call the API by force as shown in the following example:

aliyun newproduct --version 2018-01-01 --endpoint newproduct.aliyuncs.com --param1 ... --force

The following two options are required when using the --force option:

  • --version: the API version. You can find the API version in the API documentation. For example, the ECS API version is 2014-05-26.
  • --endpoint: the product endpoint. Get the product endpoint in the corresponding API documentation.

Use the --output parameter

The query interface of Alibaba Cloud products will return json structured data, which is inconvenient to read. Example:

aliyun ecs DescribeInstances

Executing the above command will get the following json result:

{
  "PageNumber": 1,
  "TotalCount": 2,
  "PageSize": 10,
  "RequestId": "2B76ECBD-A296-407E-BE17-7E668A609DDA",
  "Instances": {
    "Instance": [
      {
        "ImageId": "ubuntu_16_0402_64_20G_alibase_20171227.vhd",
        "InstanceTypeFamily": "ecs.xn4",
        "VlanId": "",
        "InstanceId": "i-12345678912345678123",
        "Status": "Stopped",
        //omit some fields
      },
      Instance": [
      {
        "ImageId": "ubuntu_16_0402_64_20G_alibase_20171227.vhd",
        "InstanceTypeFamily": "ecs.xn4",
        "VlanId": "",
        "InstanceId": "i-abcdefghijklmnopqrst",
        "Status": "Running",
        //omit some fields
      },
    ]
  }
}

You can use the --output parameter to extract the fields of interest in the results and perform tabular output. Example:

aliyun ecs DescribeInstances --output cols=InstanceId,Status rows=Instances.Instance[]

Executing the above command will get the following result:

InstanceId             | Status
-----------------------|--------
i-12345678912345678123 | Stopped
i-abcdefghijklmnopqrst | Running

When using the --output parameter, the following sub-parameters must be specified:

  • cols: The column names of the table, which need to correspond to the fields in the json data. For example, the InstanceId and Status fields in the result returned by the ECS DescribeInstances interface.

Optional sub-parameters:

  • rows: Use the jmespath query statement to specify the data source of the table row in the json result.

Use --waiter parameter

This parameter is used to poll the instance information until a specific state appears.

For example, after creating an instance using ECS, the instance will have a startup process. We will continue to query the running status of the instance until the status becomes "Running".

Example:

aliyun ecs DescribeInstances --InstanceIds '["i-12345678912345678123"]' --waiter expr='Instances.Instance[0].Status' to=Running

After executing the above command, the command line program will poll the instance status at a certain time interval and stop polling when the instance status becomes Running.

When using the --waiter parameter, you must specify the following two sub-parameters:

  • expr: Specify the polled field in the json result through the jmespath query statement.
  • to: The target value of the polled field.

Optional sub-parameters:

  • timeout: polling timeout time (seconds).
  • interval: polling interval (seconds).

Special argument

When you input some argument like "-PortRange -1/-1", will cause parse error. In this case, you could assign value like this: --PortRange=-1/-1.

Supported environment variables

We supported following environment variables:

  • ALIBABACLOUD_PROFILE/ALIBABA_CLOUD_PROFILE/ALICLOUD_PROFILE: When --profile flag is not specified, CLI use it.
  • ALIBABACLOUD_IGNORE_PROFILE=TRUE: When this variable is specified, CLI ignores any configuration files.
  • ALIBABACLOUD_ACCESS_KEY_ID/ALICLOUD_ACCESS_KEY_ID/ACCESS_KEY_ID: When no any specified Access Key Id, CLI use it.
  • ALIBABACLOUD_ACCESS_KEY_SECRET/ALICLOUD_ACCESS_KEY_SECRET/ACCESS_KEY_SECRET: When no any specified Access Key Secret, CLI use it.
  • ALIBABACLOUD_SECURITY_TOKEN/ALICLOUD_SECURITY_TOKEN/SECURITY_TOKEN: When no any specified Security Token, CLI use it.
  • ALIBABACLOUD_REGION_ID/ALICLOUD_REGION_ID/REGION: When no any specified Region Id, CLI use it.
  • DEBUG=sdk:Through this variable, CLI display http request information. It helpful for troubleshooting.
