» vault_aws_auth_backend_role

Manages an AWS auth backend role in a Vault server. Roles constrain the instances or principals that can perform the login operation against the backend. See the Vault documentation for more information.

» Argument Reference

The following arguments are supported:

  • role - (Required) The name of the role.

  • auth_type - (Optional) The auth type permitted for this role. Valid choices are ec2 and iam. Defaults to iam.

  • bound_ami_ids - (Optional) If set, defines a constraint on the EC2 instances that can perform the login operation that they should be using the AMI ID specified by this field. auth_type must be set to ec2 or inferred_entity_type must be set to ec2_instance to use this constraint.

  • bound_account_ids - (Optional) If set, defines a constraint on the EC2 instances that can perform the login operation that they should be using the account ID specified by this field. auth_type must be set to ec2 or inferred_entity_type must be set to ec2_instance to use this constraint.

  • bound_regions - (Optional) If set, defines a constraint on the EC2 instances that can perform the login operation that the region in their identity document must match the one specified by this field. auth_type must be set to ec2 or inferred_entity_type must be set to ec2_instance to use this constraint.

  • bound_vpc_ids - (Optional) If set, defines a constraint on the EC2 instances that can perform the login operation that they be associated with the VPC ID that matches the value specified by this field. auth_type must be set to ec2 or inferred_entity_type must be set to ec2_instance to use this constraint.

  • bound_subnet_ids - (Optional) If set, defines a constraint on the EC2 instances that can perform the login operation that they be associated with the subnet ID that matches the value specified by this field. auth_type must be set to ec2 or inferred_entity_type must be set to ec2_instance to use this constraint.

  • bound_iam_role_arns - (Optional) If set, defines a constraint on the EC2 instances that can perform the login operation that they must match the IAM role ARN specified by this field. auth_type must be set to ec2 or inferred_entity_type must be set to ec2_instance to use this constraint.

  • bound_iam_instance_profile_arns - (Optional) If set, defines a constraint on the EC2 instances that can perform the login operation that they must be associated with an IAM instance profile ARN which has a prefix that matches the value specified by this field. The value is prefix-matched as though it were a glob ending in *. auth_type must be set to ec2 or inferred_entity_type must be set to ec2_instance to use this constraint.

  • role_tag - (Optional) If set, enable role tags for this role. The value set for this field should be the key of the tag on the EC2 instance. auth_type must be set to ec2 or inferred_entity_type must be set to ec2_instance to use this constraint.

  • bound_iam_principal_arns - (Optional) If set, defines the IAM principal that must be authenticated when auth_type is set to iam. Wildcards are supported at the end of the ARN.

  • inferred_entity_type - (Optional) If set, instructs Vault to turn on inferencing. The only valid value is ec2_instance, which instructs Vault to infer that the role comes from an EC2 instance in an IAM instance profile. This only applies when auth_type is set to iam.

  • inferred_aws_region - (Optional) When inferred_entity_type is set, this is the region to search for the inferred entities. Required if inferred_entity_type is set. This only applies when auth_type is set to iam.

  • resolve_aws_unique_ids - (Optional) If set to true, the bound_iam_principal_arns are resolved to AWS Unique IDs for the bound principal ARN. This field is ignored when a bound_iam_principal_arn ends in a wildcard. Resolving to unique IDs more closely mimics the behavior of AWS services in that if an IAM user or role is deleted and a new one is recreated with the same name, those new users or roles won't get access to roles in Vault that were permissioned to the prior principals of the same name. Defaults to true. Once set to true, this cannot be changed to false--the role must be deleted and recreated, with the value set to true.

  • ttl - (Optional) The TTL period of tokens issued using this role, provided as a number of seconds.

  • max_ttl - (Optional) The maximum allowed lifetime of tokens issued using this role, provided as a number of seconds.

  • period - (Optional) If set, indicates that the token generated using this role should never expire. The token should be renewed within the duration specified by this value. At each renewal, the token's TTL will be set to the value of this field. The maximum allowed lifetime of token issued using this role. Specified as a number of seconds.

  • policies - (Optional) An array of strings specifying the policies to be set on tokens issued using this role.

  • allow_instance_migration - (Optional) If set to true, allows migration of the underlying instance where the client resides.

  • disallow_reauthentication - (Optional) IF set to true, only allows a single token to be granted per instance ID. This can only be set when auth_type is set to ec2.
