Below is an example configuration for the minimal amount of configuration needed to configure an assume role with web identity profile: This provider can also be configured via environment variables: AWS_ROLE_ARN - The ARN of the role you want to assume. If you want to interoperate with multiple AWS SDKs (e.g Java, JavaScript, Ruby, PHP, .NET, AWS CLI, Go, C++), use the shared credentials file (~/.aws/credentials). and should not be shared across threads and processes. All clients created from that session will share the same temporary credentials. Specify this value if the trust policy of the role being assumed includes a condition that requires MFA authentication. Below is an minimal example of the shared credentials file: The shared credentials file also supports the concept of profiles. You can provide the following values: * False - do not validate SSL certificates. :param aws_secret_access_key: The secret key to use when creating. corresponding to profiles. If you want to read the credentials again from the boto3 session then use the get_credentials( ) method. This maps to the RoleSessionName parameter in the AssumeRoleWithWebIdentity operation.
