Alibaba Cloud Credentials for Python

PyPI version Python Test codecov

Installation

  • Install with pip

Python SDK uses a common package management tool named pip. If pip is not installed, see the pip user guide to install pip.

# Install the alibabacloud_credentials
pip install alibabacloud_credentials

Usage

Before you begin, you need to sign up for an Alibaba Cloud account and retrieve your Credentials.

Credential Type

Access Key

Setup access_key credential through User Information Management, it have full authority over the account, please keep it safe. Sometimes for security reasons, you cannot hand over a primary account AccessKey with full access to the developer of a project. You may create a sub-account RAM Sub-account , grant its authorization,and use the AccessKey of RAM Sub-account.

from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config

config = Config(
    type='access_key',                    # credential type
    access_key_id='accessKeyId',          # AccessKeyId
    access_key_secret='accessKeySecret',  # AccessKeySecret
)
cred = Client(config)

access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
cred_type = cred.get_type()

STS

Create a temporary security credential by applying Temporary Security Credentials (TSC) through the Security Token Service (STS).

from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config

config = Config(
    type='sts',                           # credential type
    access_key_id='accessKeyId',          # AccessKeyId
    access_key_secret='accessKeySecret',  # AccessKeySecret
    security_token='securityToken'        # STS Token
)
cred = Client(config)

access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()

RAM Role ARN

By specifying RAM Role, the credential will be able to automatically request maintenance of STS Token. If you want to limit the permissions(How to make a policy) of STS Token, you can assign value for Policy.

from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config

config = Config(
    type='ram_role_arn',                  # credential type
    access_key_id='accessKeyId',          # AccessKeyId
    access_key_secret='accessKeySecret',  # AccessKeySecret
    security_token='securityToken',       # STS Token
    role_arn='roleArn',                   # Format: acs:ram::USER_ID:role/ROLE_NAME
    role_session_name='roleSessionName',  # Role Session Name
    policy='policy',                      # Not required, limit the permissions of STS Token
    role_session_expiration=3600          # Not required, limit the Valid time of STS Token
)
cred = Client(config)

access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()

OIDC Role ARN

By specifying OIDC Role, the credential will be able to automatically request maintenance of STS Token. If you want to limit the permissions(How to make a policy) of STS Token, you can assign value for Policy.

from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config

config = Config(
    type='oidc_role_arn',                  # credential type
    access_key_id='accessKeyId',          # AccessKeyId
    access_key_secret='accessKeySecret',  # AccessKeySecret
    security_token='securityToken',       # STS Token
    role_arn='roleArn',                   # Format: acs:ram::USER_ID:role/ROLE_NAME
    oidc_provider_arn='oidcProviderArn',  # Format: acs:ram::USER_Id:oidc-provider/OIDC Providers
    oidc_token_file_path='/Users/xxx/xxx',# oidc_token_file_path can be replaced by setting environment variable: ALIBABA_CLOUD_OIDC_TOKEN_FILE
    role_session_name='roleSessionName',  # Role Session Name
    policy='policy',                      # Not required, limit the permissions of STS Token
    role_session_expiration=3600          # Not required, limit the Valid time of STS Token
)
cred = Client(config)

access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()

ECS RAM Role

By specifying the role name, the credential will be able to automatically request maintenance of STS Token.

from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config

config = Config(
    type='ecs_ram_role',      # credential type
    role_name='roleName',     # `role_name` is optional. It will be retrieved automatically if not set. It is highly recommended to set it up to reduce requests.
    enable_imds_v2=True       # `enable_imds_v2` is optional and is recommended to be turned on. It can be replaced by setting environment variable: ALIBABA_CLOUD_ECS_IMDSV2_ENABLE
)
cred = Client(config)

access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()

Credentials URI

By specifying a credentials uri, get credential from the local or remote uri, the credential will be able to automatically request maintenance to keep it update.

from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config

config = Config(
    type='credentials_uri',                        # credential type
    credentials_uri='http://local_or_remote_uri/', # Credentials URI
)
cred = Client(config)

access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()

Bearer

If credential is required by the Cloud Call Centre (CCC), please apply for Bearer Token maintenance by yourself.

from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config

config = Config(
    type='bearer',                        # credential type
    bearer_token='bearerToken',           # BearerToken
)
cred = Client(config)

access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()

Use the default credential provider chain

from alibabacloud_credentials.client import Client as CredClient
from alibabacloud_ocr20191230.client import Client as OcrClient
from alibabacloud_ocr20191230.models import GetAsyncJobResultRequest
from alibabacloud_tea_rpc.models import Config
from alibabacloud_tea_util.models import RuntimeOptions

cred = CredClient()
config = Config(credential=cred)

client = OcrClient(config)

request = GetAsyncJobResultRequest(
    job_id='<job_id>'
)

runtime_options = RuntimeOptions()
response = client.get_async_job_result(request, runtime_options)

The default credential provider chain looks for available credentials, with following order:

  1. Environment Credentials

    Look for environment credentials in environment variable. If the ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variables are defined and are not empty, the program will use them to create default credentials. If the ALIBABA_CLOUD_ACCESS_KEY_ID, ALIBABA_CLOUD_ACCESS_KEY_SECRET and ALIBABA_CLOUD_SECURITY_TOKEN environment variables are defined and are not empty, the program will use them to create temporary security credentials(STS). Note: This token has an expiration time, it is recommended to use it in a temporary environment.

  2. Credentials File

    If there is ~/.alibabacloud/credentials.ini default file (Windows shows C:\Users\USER_NAME\.alibabacloud\credentials.ini), the program automatically creates credentials with the specified type and name. The default file is not necessarily exist, but a parse error will throw an exception. The name of configuration item is lowercase.This configuration file can be shared between different projects and between different tools. Because it is outside of the project and will not be accidentally committed to the version control. The path to the default file can be modified by defining the ALIBABA_CLOUD_CREDENTIALS_FILE environment variable. If not configured, use the default configuration default. You can also set the environment variables ALIBABA_CLOUD_PROFILE to use the configuration.

    [default]                          # default setting
    enable = true                      # Enable,Enabled by default if this option is not present
    type = access_key                  # Certification type: access_key
    access_key_id = foo                # Key
    access_key_secret = bar            # Secret
    
    [client1]                          # configuration that is named as `client1`
    type = ecs_ram_role                # Certification type: ecs_ram_role
    role_name = EcsRamRoleTest         # Role Name
    
    [client2]                          # configuration that is named as `client2`
    enable = false                     # Disable
    type = ram_role_arn                # Certification type: ram_role_arn
    region_id = cn-test
    policy = test                      # optional Specify permissions
    access_key_id = foo
    access_key_secret = bar
    role_arn = role_arn
    role_session_name = session_name   # optional
    
    [client3]                          # configuration that is named as `client3`
    enable = false                     # Disable
    type = oidc_role_arn               # Certification type: oidc_role_arn
    region_id = cn-test                 
    policy = test                      # optional Specify permissions
    access_key_id = foo                # optional
    access_key_secret = bar            # optional
    role_arn = role_arn
    oidc_provider_arn = oidc_provider_arn
    oidc_token_file_path = /xxx/xxx    # can be replaced by setting environment variable: ALIBABA_CLOUD_OIDC_TOKEN_FILE              
    role_session_name = session_name   # optional
    
  3. Instance RAM Role

    If the environment variable ALIBABA_CLOUD_ECS_METADATA is defined and not empty, the program will take the value of the environment variable as the role name and request http://100.100.100.200/latest/meta-data/ram/security-credentials/ to get the temporary Security credentials.

  4. Credentials URI

    If the environment variable ALIBABA_CLOUD_CREDENTIALS_URI is defined and not empty, the program will take the value of the environment variable as credentials uri to get the temporary Security credentials.
