Method: instances.startWithEncryptionKey

Starts an instance that was stopped using the instances().stop method. For more information, see Restart an instance.

HTTP request

POST https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/instances/{instance}/startWithEncryptionKey

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.
zone

string

The name of the zone for this request.
instance

string

Name of the instance resource to start.

Query parameters

Parameters
requestId

string

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.

For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

Request body

The request body contains data with the following structure:

JSON representation 
{
  "disks": [
    {
      "source": string,
      "diskEncryptionKey": {
        "sha256": string,
        "kmsKeyServiceAccount": string,

        
        "rawKey": string,
        "rsaEncryptedKey": string,
        "kmsKeyName": string
        
      }
    }
  ]
}
Fields
disks[]

object

Array of disks associated with this instance that are protected with a customer-supplied encryption key.

In order to start the instance, the disk url and its corresponding key must be provided.

If the disk is not protected with a customer-supplied encryption key it should not be specified.
disks[].source

string

Specifies a valid partial or full URL to an existing Persistent Disk resource. This field is only applicable for persistent disks. For example: 

"source": "/compute/v1/projects/ projectId/zones/ zone/disks/ diskName

disks[].diskEncryptionKey

object

Decrypts data associated with the disk with a customer-supplied encryption key.
disks[].diskEncryptionKey.rawKey

string

Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource. You can provide either the rawKey or the rsaEncryptedKey. For example: 

"rawKey": "SGVsbG8gZnJvbSBHb29nbGUgQ2xvdWQgUGxhdGZvcm0="

disks[].diskEncryptionKey.rsaEncryptedKey

string

Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource. You can provide either the rawKey or the rsaEncryptedKey. For example: 

"rsaEncryptedKey": "ieCx/NcW06PcT7Ep1X6LUTc/hLvUDYyzSZPPVCVPTVEohpeHASqC8uw5TzyO9U+Fka9JFH z0mBibXUInrC/jEk014kCK/NPjYgEMOyssZ4ZINPKxlUh2zn1bV+MCaTICrdmuSBTWlUUiFoD D6PYznLwh8ZNdaheCeZ8ewEXgFQ8V+sDroLaN3Xs3MDTXQEMMoNUXMCZEIpg9Vtp9x2oe=="
The key must meet the following requirements before you can provide it to Compute Engine:
  1. The key is wrapped using a RSA public key certificate provided by Google.
  2. After being wrapped, the key must be encoded in RFC 4648 base64 encoding.
Gets the RSA public key certificate provided by Google at: 
 https://cloud-certs.storage.googleapis.com/google-cloud-csek-ingress.pem
disks[].diskEncryptionKey.kmsKeyName

string

The name of the encryption key that is stored in Google Cloud KMS. For example: 

"kmsKeyName": "projects/ kms_project_id/locations/ region/keyRings/ key_region/cryptoKeys/key
The fully-qualifed key name may be returned for resource GET requests. For example: 
"kmsKeyName": "projects/ kms_project_id/locations/ region/keyRings/ key_region/cryptoKeys/key /cryptoKeyVersions/1
disks[].diskEncryptionKey.sha256

string

[Output only] The RFC 4648 base64 encoded SHA-256 hash of the customer-supplied encryption key that protects this resource.
disks[].diskEncryptionKey.kmsKeyServiceAccount

string

The service account being used for the encryption request for the given KMS key. If absent, the Compute Engine default service account is used. For example: 

"kmsKeyServiceAccount": "name@ projectId.iam.gserviceaccount.com/

Response body

Represents an Operation resource.

Google Compute Engine has three Operation resources:

You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.

Operations can be global, regional or zonal.

  • For global operations, use the globalOperations resource.
  • For regional operations, use the regionOperations resource.
  • For zonal operations, use the zoneOperations resource.

For more information, read Global, Regional, and Zonal Resources.

Note that completed Operation resources have a limited retention period.

If successful, the response body contains data with the following structure:

startTime

string

[Output Only] The time that this operation was started by the server. This value is in RFC3339 text format.

error.errors[].location

string

[Output Only] Indicates the field in the request that caused the error. This property is optional.
error.errors[].message

string

[Output Only] An optional, human-readable error message.
error.errors[].errorDetails[]

object

[Output Only] An optional list of messages that contain the error details. There is a set of defined message types to use for providing details.The syntax depends on the error code. For example, QuotaExceededInfo will have details when the error code is QUOTA_EXCEEDED.

object
error.errors[].errorDetails[].errorInfo.reason

string

The reason of the error. This is a constant value that identifies the proximate cause of the error. Error reasons are unique within a particular domain of errors. This should be at most 63 characters and match a regular expression of [A-Z][A-Z0-9_]+[A-Z0-9], which represents UPPER_SNAKE_CASE.
error.errors[].errorDetails[].errorInfo.domain

string

The logical grouping to which the "reason" belongs. The error domain is typically the registered service name of the tool or product that generates the error. Example: "pubsub.googleapis.com". If the error is generated by some common infrastructure, the error domain must be a globally unique value that identifies the infrastructure. For Google API infrastructure, the error domain is "googleapis.com".
error.errors[].errorDetails[].errorInfo.metadatas

map (key: string, value: string)

Additional structured details about this error.

Keys must match /[a-z][a-zA-Z0-9-_]+/ but should ideally be lowerCamelCase. Also they must be limited to 64 characters in length. When identifying the current value of an exceeded limit, the units should be contained in the key, not the value. For example, rather than {"instanceLimit": "100/request"}, should be returned as, {"instanceLimitPerRequest": "100"}, if the client exceeds the number of instances that can be created in a single (batch) request.

warnings[].data[].value

string

[Output Only] A warning data value corresponding to the key.
