AwsConnectionParams

Contains connection parameters to authenticate against Amazon Web Services (AWS) and connect to specific AWS resources.

Implements: IConfigurable, IReferenceable

Description

The AwsConnectionParams class contains connection parameters used to authenticate against Amazon Web Services (AWS) and connect to specific AWS resources.

Important points

  • This class is able to compose and parse AWS resource ARNs.

Configuration parameters

  • access_id: application access id
  • client_id: alternative to access_id
  • access_key: application secret key
  • client_key: alternative to access_key
  • secret_key: alternative to access_key

In addition to standard parameters, CredentialParams may contain any number of custom parameters

Constructors

Creates an new instance of the connection parameters.

AwsConnectionParams(values: Any = None)

  • values: Any - (optional) object to be converted into key-value pairs to initialize this connection.

Instance methods

get_access_id

Gets the AWS access id.

get_access_id(): str

  • returns: str - AWS access id.

get_access_key

Gets the AWS client key.

get_access_key(): str

  • returns: str - AWS client key.

get_account

Gets the AWS account id.

get_account(): str

  • returns: str - AWS account id.

get_arn

Gets the AWS resource ARN. If the ARN is not defined, it automatically generates it from other properties.

get_arn(): str

  • returns: str - AWS resource ARN.

get_partition

Gets the AWS partition name.

get_partition(): str

  • returns: str - AWS partition name.

get_region

Gets the AWS region.

get_region(): str

  • returns: str - AWS region.

get_resource

Gets the AWS resource id.

get_resource(): str

  • returns: str - AWS resource id.

get_resource_type

Gets the AWS resource type.

get_resource_type(): str

  • returns: str - AWS resource type.

get_service

Gets the AWS service name.

get_service(): str

  • returns: str - AWS service name.

set_access_id

Sets the AWS access id.

set_access_id(value: str)

  • value: str - AWS access id.

set_access_key

Sets the AWS client key.

set_access_key(value: str)

  • value: str - new AWS client key.

set_account

Sets the AWS account id.

set_account(value: str)

  • value: str - AWS account id.

set_arn

Sets the AWS resource ARN. When it sets the value, it automatically parses the ARN and sets individual parameters.

set_arn(value: str)

  • value: str - new AWS resource ARN.

set_partition

Sets the AWS partition name.

set_partition(value: str)

  • value: str - new AWS partition name.

set_region

Sets the AWS region.

set_region(value: str)

  • value: str - new AWS region.

set_resource

Sets the AWS resource id.

set_resource(value: str)

  • value: str - new AWS resource id.

set_resource_type

Sets the AWS resource type.

set_resource_type(value: str)

  • value: str - new AWS resource type.

set_service

Sets the AWS service name.

set_service(value: str)

  • value: str - new AWS service name.

validate

Validates this connection parameters

validate(context: Optional[IContext])

  • context: IContext - (optional) a context to trace execution through a call chain.

Static methods

from_config

Retrieves AwsConnectionParams from configuration parameters. The values are retrieved from “connection” and “credential” sections.

See mergeConfigs

static from_config(config: ConfigParams): AwsConnectionParams

from_string

Creates a new AwsConnectionParams object filled with key-value pairs serialized as a string.

Example: “Key1=123;Key2=ABC;Key3=2016-09-16T00:00:00.00Z”

static from_string(line: str): AwsConnectionParams

  • line: str - string with serialized key-value pairs as “key1=value1;key2=value2;…”.
  • returns: AwsConnectionParams - new AwsConnectionParams object.

merge_configs

Retrieves AwsConnectionParams from multiple configuration parameters. The values are retrieved from “connection” and “credential” sections.

static merge_configs(*configs: ConfigParams): AwsConnectionParams

Examples

connection = AwsConnectionParams.from_tuples(
    "region", "us-east-1",
    "access_id", "XXXXXXXXXXXXXXX",
    "secret_key", "XXXXXXXXXXXXXXX",
    "service", "s3",
    "bucket", "mybucket"
)

region = connection.get_region()                      # Result: "us-east-1"
access_id = connection.get_access_id()                # Result: "XXXXXXXXXXXXXXX"
secret_key = connection.get_access_key()              # Result: "XXXXXXXXXXXXXXX"
pin = connection.get_as_nullable_string("bucket")     # Result: "mybucket"
