REST Resource: projects.locations.workstationClusters.workstationConfigs

Resource: WorkstationConfig

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) rules to grant access to teams or to individual developers.

Output only. Time when this workstation configuration was created.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".
updateTime

string (Timestamp format)

Output only. Time when this workstation configuration was most recently updated.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".
deleteTime

string (Timestamp format)

Output only. Time when this workstation configuration was soft-deleted.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".
etag

string

Optional. Checksum computed by the server. May be sent on update and delete requests to make sure that the client has an up-to-date value before proceeding.
idleTimeout

string (Duration format)

Optional. Number of seconds to wait before automatically stopping a workstation after it last received user traffic.

A value of "0s" indicates that Cloud Workstations VMs created with this configuration should never time out due to idleness. Provide duration terminated by s for seconds—for example, "7200s" (2 hours). The default is "1200s" (20 minutes).

A duration in seconds with up to nine fractional digits, ending with 's'. Example: "3.5s".
runningTimeout

string (Duration format)

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 idleTimeout and runningTimeout fields are independent of each other. Note that the runningTimeout 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, "54000s" (15 hours). Defaults to "43200s" (12 hours). A value of "0s" indicates that workstations using this configuration should never time out. If encryptionKey is set, it must be greater than "0s" and less than "86400s" (24 hours).

Warning: A value of "0s" indicates that Cloud Workstations VMs created with this configuration have no maximum running time. This is strongly discouraged because you incur costs and will not pick up security updates.

A duration in seconds with up to nine fractional digits, ending with 's'. Example: "3.5s".
maxUsableWorkstations

integer

Optional. Maximum number of workstations under this configuration a user can have workstations.workstation.use permission on.

Only enforced on CreateWorkstation API calls on the user issuing the API request. Can be overridden by:

  • granting a user workstations.workstationConfigs.exemptMaxUsableWorkstationLimit permission, or
  • having a user with that permission create a workstation and granting another user workstations.workstation.use permission on that workstation.

If not specified, defaults to 0, which indicates unlimited.
host

object (Host)

Optional. Runtime host for the workstation.
persistentDirectories[]

object (PersistentDirectory)

Optional. Directories to persist across workstation sessions.
ephemeralDirectories[]

object (EphemeralDirectory)

Optional. Ephemeral directories which won't persist across workstation sessions.
container

object (Container)

Optional. Container that runs upon startup for each workstation using this workstation configuration.
encryptionKey

object (CustomerEncryptionKey)

Immutable. 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.

string

Optional. Immutable. Specifies the zones used to replicate the VM and disk resources within the region. If set, exactly two zones within the workstation cluster's region must be specified—for example, ['us-central1-a', 'us-central1-f']. If this field is empty, two default zones within the region are used.

Immutable after the workstation configuration is created.

When enabled, a serviceAccount 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 and Container output logging. Operating system audit logs are available in the Cloud Logging console by querying:

resource.type="gceInstance"
logName:"/logs/linux-auditd"
httpOptions

object (HttpOptions)

Optional. HTTP options that customize the behavior of the workstation service's HTTP proxy.
disableTcpConnections

boolean

Optional. Disables support for plain TCP connections in the workstation. By default the service supports TCP connections through a websocket relay.

serviceAccount

string

Optional. The email address of the service account for Cloud Workstations VMs created with this configuration. 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 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'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.
