  body: object, The request body.
    The object takes the form of:

{ # A workstation configuration resource in the Cloud Workstations API. Workstation configurations act as templates for workstations. The workstation configuration defines details such as the workstation virtual machine (VM) instance type, persistent storage, container image defining environment, which IDE or Code Editor to use, and more. Administrators and platform teams can also use [Identity and Access Management (IAM)](https://cloud.google.com/iam/docs/overview) rules to grant access to teams or to individual developers.
  &quot;allowedPorts&quot;: [ # Optional. A list of PortRanges specifying single ports or ranges of ports that are externally accessible in the workstation. Allowed ports must be one of 22, 80, or within range 1024-65535. If not specified defaults to ports 22, 80, and ports 1024-65535.

  },
  &quot;conditions&quot;: [ # Output only. Status conditions describing the workstation configuration&#x27;s current state.
    { # The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the [API Design Guide](https://cloud.google.com/apis/design/errors).
      &quot;code&quot;: 42, # The status code, which should be an enum value of google.rpc.Code.
      &quot;details&quot;: [ # A list of messages that carry the error details. There is a common set of message types for APIs to use.

      &quot;a_key&quot;: &quot;A String&quot;,
    },
    &quot;image&quot;: &quot;A String&quot;, # Optional. A Docker container image that defines a custom environment. Cloud Workstations provides a number of [preconfigured images](https://cloud.google.com/workstations/docs/preconfigured-base-images), but you can create your own [custom container images](https://cloud.google.com/workstations/docs/custom-container-images). If using a private image, the `host.gceInstance.serviceAccount` field must be specified in the workstation configuration. If using a custom container image, the service account must have [Artifact Registry Reader](https://cloud.google.com/artifact-registry/docs/access-control#roles) permission to pull the specified image.

  &quot;displayName&quot;: &quot;A String&quot;, # Optional. Human-readable name for this workstation configuration.
  &quot;enableAuditAgent&quot;: True or False, # Optional. Whether to enable Linux `auditd` logging on the workstation. When enabled, a service_account must also be specified that has `roles/logging.logWriter` and `roles/monitoring.metricWriter` on the project. Operating system audit logging is distinct from [Cloud Audit Logs](https://cloud.google.com/workstations/docs/audit-logging) and [Container output logging](https://cloud.google.com/workstations/docs/container-output-logging#overview). Operating system audit logs are available in the [Cloud Logging](https://cloud.google.com/logging/docs) console by querying: resource.type=&quot;gce_instance&quot; log_name:&quot;/logs/linux-auditd&quot;
  &quot;encryptionKey&quot;: { # A customer-managed encryption key (CMEK) for the Compute Engine resources of the associated workstation configuration.

Encrypts resources of this workstation configuration using a customer-managed encryption key (CMEK). If specified, the boot disk of the Compute Engine instance and the persistent disk are encrypted using this encryption key. If this field is not set, the disks are encrypted using a generated key. Customer-managed encryption keys do not protect disk metadata. If the customer-managed encryption key is rotated, when the workstation instance is stopped, the system attempts to recreate the persistent disk with the new version of the key. Be sure to keep older versions of the key until the persistent disk is recreated. Otherwise, data on the persistent disk might be lost. If the encryption key is revoked, the workstation session automatically stops within 7 hours. Immutable after the workstation configuration is created.
    &quot;kmsKey&quot;: &quot;A String&quot;, # Immutable. The name of the Google Cloud KMS encryption key. For example, `&quot;projects/PROJECT_ID/locations/REGION/keyRings/KEY_RING/cryptoKeys/KEY_NAME&quot;`. The key must be in the same region as the workstation configuration.
    &quot;kmsKeyServiceAccount&quot;: &quot;A String&quot;, # Immutable. The service account to use with the specified KMS key. We recommend that you use a separate service account and follow KMS best practices. For more information, see [Separation of duties](https://cloud.google.com/kms/docs/separation-of-duties) and `gcloud kms keys add-iam-policy-binding` [`--member`](https://cloud.google.com/sdk/gcloud/reference/kms/keys/add-iam-policy-binding#--member).

  &quot;runningTimeout&quot;: &quot;A String&quot;, # Optional. Number of seconds that a workstation can run until it is automatically shut down. We recommend that workstations be shut down daily to reduce costs and so that security updates can be applied upon restart. The idle_timeout and running_timeout fields are independent of each other. Note that the running_timeout field shuts down VMs after the specified time, regardless of whether or not the VMs are idle. Provide duration terminated by `s` for seconds—for example, `&quot;54000s&quot;` (15 hours). Defaults to `&quot;43200s&quot;` (12 hours).

      &quot;enableNestedVirtualization&quot;: True or False, # Optional. Whether to enable nested virtualization on Cloud Workstations VMs created using this workstation configuration. Defaults to false. Nested virtualization lets you run virtual machine (VM) instances inside your workstation. Before enabling nested virtualization, consider the following important considerations. Cloud Workstations instances are subject to the [same restrictions as Compute Engine instances](https://cloud.google.com/compute/docs/instances/nested-virtualization/overview#restrictions): * **Organization policy**: projects, folders, or organizations may be restricted from creating nested VMs if the **Disable VM nested virtualization** constraint is enforced in the organization policy. For more information, see the Compute Engine section, [Checking whether nested virtualization is allowed](https://cloud.google.com/compute/docs/instances/nested-virtualization/managing-constraint#checking_whether_nested_virtualization_is_allowed). * **Performance**: nested VMs might experience a 10% or greater decrease in performance for workloads that are CPU-bound and possibly greater than a 10% decrease for workloads that are input/output bound. * **Machine Type**: nested virtualization can only be enabled on workstation configurations that specify a machine_type in the N1 or N2 machine series.
      &quot;machineType&quot;: &quot;A String&quot;, # Optional. The type of machine to use for VM instances—for example, `&quot;e2-standard-4&quot;`.

      &quot;reservationAffinity&quot;: { # ReservationAffinity is the configuration of the desired reservation from which instances can consume resources. # Optional. [ReservationAffinity](https://cloud.google.com/compute/docs/instances/reserving-zonal-resources) specifies a reservation that can be consumed to create VM instances. If SPECIFIC_RESERVATION is specified, Cloud Workstations will only create VMs in the zone where the reservation is located. This would affect availability since the service will no longer be resilient to zonal outages. If ANY_RESERVATION is specified, creating reservations in both zones that the config creates VMs in will ensure higher availability. **Important Considerations for Reservation Affinity:** * This feature is intended for advanced users and requires familiarity with Google Compute Engine reservations. * Using reservations incurs charges, regardless of utilization. * The resources in the pool will consume the specified reservation. Take this into account when setting the pool size.

When specified, be sure that the service account has `logging.logEntries.create` and `monitoring.timeSeries.create` permissions on the project so it can write logs out to Cloud Logging. If using a custom container image, the service account must have [Artifact Registry Reader](https://cloud.google.com/artifact-registry/docs/access-control#roles) permission to pull the specified image. If you as the administrator want to be able to `ssh` into the underlying VM, you need to set this value to a service account for which you have the `iam.serviceAccounts.actAs` permission. Conversely, if you don&#x27;t want anyone to be able to `ssh` into the underlying VM, use a service account where no one has that permission. If not set, VMs run with a service account provided by the Cloud Workstations service, and the image must be publicly accessible.

By default, the workstations service replaces references to localhost, 127.0.0.1, and 0.0.0.0 with the workstation&#x27;s hostname in http responses from the workstation so that applications under development run properly on the workstation. This may intefere with some applications, and so this option allows that behavior to be disabled.
  },
  &quot;idleTimeout&quot;: &quot;A String&quot;, # Optional. Number of seconds to wait before automatically stopping a workstation after it last received user traffic. A value of `&quot;0s&quot;` indicates that Cloud Workstations VMs created with this configuration should never time out due to idleness.

<div class="method">
    <code class="details" id="getIamPolicy">getIamPolicy(resource, options_requestedPolicyVersion=None, x__xgafv=None)</code>
  <pre>Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

Args:
  resource: string, REQUIRED: The resource for which the policy is being requested. See [Resource names](https://cloud.google.com/apis/design/resource_names) for the appropriate value for this field. (required)
  options_requestedPolicyVersion: integer, Optional. The maximum policy version that will be used to format the policy. Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected. Requests for policies with any conditional role bindings must specify version 3. Policies with no conditional role bindings may specify any valid value or leave the field unset. The policy in the response might use the policy version that you specified, or it might use a lower policy version. For example, if you specify version 3, but the policy has no conditional role bindings, the response uses version 1.

  An object of the form:

    { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { &quot;bindings&quot;: [ { &quot;role&quot;: &quot;roles/resourcemanager.organizationAdmin&quot;, &quot;members&quot;: [ &quot;user:mike@example.com&quot;, &quot;group:admins@example.com&quot;, &quot;domain:google.com&quot;, &quot;serviceAccount:my-project-id@appspot.gserviceaccount.com&quot; ] }, { &quot;role&quot;: &quot;roles/resourcemanager.organizationViewer&quot;, &quot;members&quot;: [ &quot;user:eve@example.com&quot; ], &quot;condition&quot;: { &quot;title&quot;: &quot;expirable access&quot;, &quot;description&quot;: &quot;Does not grant access after Sep 2020&quot;, &quot;expression&quot;: &quot;request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;)&quot;, } } ], &quot;etag&quot;: &quot;BwWWja0YfJA=&quot;, &quot;version&quot;: 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;) etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).

If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost.
  &quot;version&quot;: 42, # Specifies the format of the policy. Valid values are `0`, `1`, and `3`. Requests that specify an invalid value are rejected. Any operation that affects conditional role bindings must specify version `3`. This requirement applies to the following operations: * Getting a policy that includes a conditional role binding * Adding a conditional role binding to a policy * Changing a conditional role binding in a policy * Removing any role binding, with or without a condition, from a policy that includes conditions **Important:** If you use IAM Conditions, you must include the `etag` field whenever you call `setIamPolicy`. If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

This would affect availability since the service will no longer be resilient to zonal outages. If ANY_RESERVATION is specified, creating reservations in both zones that the config creates VMs in will ensure higher availability. **Important Considerations for Reservation Affinity:** * This feature is intended for advanced users and requires familiarity with Google Compute Engine reservations. * Using reservations incurs charges, regardless of utilization. * The resources in the pool will consume the specified reservation. Take this into account when setting the pool size.

  <pre>Sets the access control policy on the specified resource. Replaces any existing policy. Can return `NOT_FOUND`, `INVALID_ARGUMENT`, and `PERMISSION_DENIED` errors.

Args:
  resource: string, REQUIRED: The resource for which the policy is being specified. See [Resource names](https://cloud.google.com/apis/design/resource_names) for the appropriate value for this field. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for `SetIamPolicy` method.
  &quot;policy&quot;: { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { &quot;bindings&quot;: [ { &quot;role&quot;: &quot;roles/resourcemanager.organizationAdmin&quot;, &quot;members&quot;: [ &quot;user:mike@example.com&quot;, &quot;group:admins@example.com&quot;, &quot;domain:google.com&quot;, &quot;serviceAccount:my-project-id@appspot.gserviceaccount.com&quot; ] }, { &quot;role&quot;: &quot;roles/resourcemanager.organizationViewer&quot;, &quot;members&quot;: [ &quot;user:eve@example.com&quot; ], &quot;condition&quot;: { &quot;title&quot;: &quot;expirable access&quot;, &quot;description&quot;: &quot;Does not grant access after Sep 2020&quot;, &quot;expression&quot;: &quot;request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;)&quot;, } } ], &quot;etag&quot;: &quot;BwWWja0YfJA=&quot;, &quot;version&quot;: 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;) etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/). # REQUIRED: The complete policy to be applied to the `resource`.

    { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { &quot;bindings&quot;: [ { &quot;role&quot;: &quot;roles/resourcemanager.organizationAdmin&quot;, &quot;members&quot;: [ &quot;user:mike@example.com&quot;, &quot;group:admins@example.com&quot;, &quot;domain:google.com&quot;, &quot;serviceAccount:my-project-id@appspot.gserviceaccount.com&quot; ] }, { &quot;role&quot;: &quot;roles/resourcemanager.organizationViewer&quot;, &quot;members&quot;: [ &quot;user:eve@example.com&quot; ], &quot;condition&quot;: { &quot;title&quot;: &quot;expirable access&quot;, &quot;description&quot;: &quot;Does not grant access after Sep 2020&quot;, &quot;expression&quot;: &quot;request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;)&quot;, } } ], &quot;etag&quot;: &quot;BwWWja0YfJA=&quot;, &quot;version&quot;: 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;) etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).
