NAME
gcloud iam service-accounts add-iam-policy-binding - add an IAM policy binding to an IAM service account
SYNOPSIS
gcloud iam service-accounts add-iam-policy-binding SERVICE_ACCOUNT --member=MEMBER --role=ROLE [--condition=[KEY=VALUE,…]     | --condition-from-file=CONDITION_FROM_FILE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
Add an IAM policy binding to an IAM service account. A binding consists of at least one member, a role, and an optional condition.

When managing IAM roles, you can treat a service account either as a resource or as an identity. This command adds an IAM policy binding to a service account resource. There are other gcloud commands to manage IAM policies for other types of resources. For example, to manage IAM policies on a project, use the $ gcloud projects commands.

POSITIONAL ARGUMENTS
ServiceAccount resource - The Service Account to which to add the IAM policy binding. This represents a Cloud 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 [service_account] 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.
SERVICE_ACCOUNT
ID of the serviceAccount or fully qualified identifier for the serviceAccount.
REQUIRED FLAGS
--member=MEMBER
The member to add the binding for. Should be of the form user|group|serviceAccount:email or domain:domain.

Examples: user:test-user@gmail.com, group:admins@example.com, serviceAccount:test123@example.domain.com, or domain:example.domain.com.

Can also be one of the following special values:

  • allUsers - Special identifier that represents anyone who is on the internet, with or without a Google account.
  • allAuthenticatedUsers - Special identifier that represents anyone who is authenticated with a Google account or a service account.
--role=ROLE
Define the role of the member.
OPTIONAL FLAGS
At most one of these may be specified:
--condition=[KEY=VALUE,…]
The condition of the binding to be added. When the condition is explicitly specified as None (--condition=None), a binding without a condition is added. When the condition is specified and is not None, --role cannot be a primitive role. Primitive roles are roles/editor, roles/owner, and roles/viewer.
expression
(Required) Expression of the condition which evaluates to True or False. This uses a subset of Common Expression Language syntax.
title
(Required) A short string describing the purpose of the expression.
description
(Optional) Additional description for the expression.

NOTE: An unsatisfied condition will not allow access via this binding.

--condition-from-file=CONDITION_FROM_FILE
Path to a local JSON or YAML file that defines the condition. To see available fields, see the help for --condition.
