gcloud iam workload-identity-pools providers create-aws - create a new AWS workload identity pool provider
gcloud iam workload-identity-pools providers create-aws (PROVIDER : --location=LOCATION --workload-identity-pool=WORKLOAD_IDENTITY_POOL) --account-id=ACCOUNT_ID [--attribute-condition=ATTRIBUTE_CONDITION] [--attribute-mapping=[ATTRIBUTE_MAPPING,...]] [--description=DESCRIPTION] [--disabled] [--display-name=DISPLAY_NAME] [GCLOUD_WIDE_FLAG ...]
Create a new AWS workload identity pool provider.
The following command creates a disabled AWS workload identity pool provider in the default project with the ID my-workload-identity-pool. Explicit values for all required and optional parameters are provided.
$ gcloud iam workload-identity-pools providers create-aws \ my-workload-identity-pool-provider --location="global" \ --workload-identity-pool="my-workload-identity-pool" \ --display-name="My workload pool provider" \ --description="My workload pool provider description" \ --disabled --attribute-mapping="google.subject=assertion.arn" \ --attribute-condition="true" --account-id=1234567890
- Workload identity pool provider resource - The workload identity pool provider
to create. The arguments in this group can be used to specify the attributes of this resource. (NOTE) Some attributes are not given arguments in this group but can be set in other ways. To set the project attribute:
- —
provide the argument provider on the command line with a fully specified name;
- —
set the property core/project;
- —
provide the argument --project on the command line.
This must be specified.
- PROVIDER
ID of the workload identity pool provider or fully qualified identifier for the workload identity pool provider. To set the provider attribute:
provide the argument provider on the command line.
This positional argument must be specified if any of the other arguments in this group are specified.
- --location=LOCATION
The location name. To set the location attribute:
provide the argument provider on the command line with a fully specified name;
provide the argument --location on the command line.
- --workload-identity-pool=WORKLOAD_IDENTITY_POOL
The ID to use for the pool, which becomes the final component of the resource name. This value should be 4-32 characters, and may contain the characters [a-z0-9-]. The prefix gcp- is reserved for use by Google, and may not be specified.
To set the workload-identity-pool attribute:
provide the argument provider on the command line with a fully specified name;
provide the argument --workload-identity-pool on the command line.
- --account-id=ACCOUNT_ID
The AWS account ID.
- --attribute-condition=ATTRIBUTE_CONDITION
A Common Expression Language https://opensource.google/projects/cel expression, in plain text, to restrict what otherwise valid authentication credentials issued by the provider should not be accepted.
The expression must output a boolean representing whether to allow the federation.
The following keywords may be referenced in the expressions:
- —
assertion: JSON representing the authentication credential issued by the provider.
- —
google: The Google attributes mapped from the assertion in the attribute_mappings.
- —
attribute: The custom attributes mapped from the assertion in the attribute_mappings.
The maximum length of the attribute condition expression is 4096 characters. If unspecified, all valid authentication credential are accepted.
The following example shows how to only allow credentials with a mapped google.groups value of admins:
"'admins' in google.groups"
- --attribute-mapping=[ATTRIBUTE_MAPPING,...]
Maps attributes from authentication credentials issued by an external identity provider to Google Cloud attributes, such as subject and segment.
Each key must be a string specifying the Google Cloud IAM attribute to map to.
The following keys are supported:
- —
google.subject: The principal IAM is authenticating. You can reference this value in IAM bindings. This is also the subject that appears in Cloud Logging logs. Cannot exceed 127 bytes.
- —
google.groups: Groups the external identity belongs to. You can grant groups access to resources using an IAM principalSet binding; access applies to all members of the group.
You can also provide custom attributes by specifying attribute.{custom_attribute}, where {custom_attribute} is the name of the custom attribute to be mapped. You can define a maximum of 50 custom attributes. The maximum length of a mapped attribute key is 100 characters, and the key may only contain the characters [a-z_0-9].
You can reference these attributes in IAM policies to define fine-grained access for a workload to Google Cloud resources. For example:
- —
google.subject: principal://iam.googleapis.com/projects/{project}/locations/{location}/workloadIdentityPools/{pool}/subject/{value}
- —
google.groups: principalSet://iam.googleapis.com/projects/{project}/locations/{location}/workloadIdentityPools/{pool}/group/{value}
- —
attribute.{custom_attribute}: principalSet://iam.googleapis.com/projects/{project}/locations/{location}/workloadIdentityPools/{pool}/attribute.{custom_attribute}/{value}
Each value must be a [Common Expression Language] https://opensource.google/projects/cel function that maps an identity provider credential to the normalized attribute specified by the corresponding map key.
You can use the assertion keyword in the expression to access a JSON representation of the authentication credential issued by the provider.
The maximum length of an attribute mapping expression is 2048 characters. When evaluated, the total size of all mapped attributes must not exceed 8KB.
For AWS providers, the following rules apply:
- —
If no attribute mapping is defined, the following default mapping applies:
{ "google.subject":"assertion.arn", "attribute.aws_role": "assertion.arn.contains('assumed-role')" " ? assertion.arn.extract('{account_arn}assumed-role/')" " + 'assumed-role/'" " + assertion.arn.extract('assumed-role/{role_name}/')" " : assertion.arn", }
- —
If any custom attribute mappings are defined, they must include a mapping to the google.subject attribute.
For OIDC providers, the following rules apply:
- —
Custom attribute mappings must be defined, and must include a mapping to the google.subject attribute. For example, the following maps the sub claim of the incoming credential to the subject attribute on a Google token.
{"google.subject": "assertion.sub"}
- --description=DESCRIPTION
A description for the provider. Cannot exceed 256 characters.
- --disabled
Whether the provider is disabled. You cannot use a disabled provider to exchange tokens. However, existing tokens still grant access.
- --display-name=DISPLAY_NAME
A display name for the provider. Cannot exceed 32 characters.
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.
