start-stream-encryption

Description

Enables or updates server-side encryption using an Amazon Web Services KMS key for a specified stream.

Starting encryption is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns immediately and sets the status of the stream to UPDATING . After the update is complete, Kinesis Data Streams sets the status of the stream back to ACTIVE . Updating or applying encryption normally takes a few seconds to complete, but it can take minutes. You can continue to read and write data to your stream while its status is UPDATING . Once the status of the stream is ACTIVE , encryption begins for records written to the stream.

API Limits: You can successfully apply a new Amazon Web Services KMS key for server-side encryption 25 times in a rolling 24-hour period.

Note: It can take up to 5 seconds after the stream is in an ACTIVE status before all records written to the stream are encrypted. After you enable encryption, you can verify that encryption is applied by inspecting the API response from PutRecord or PutRecords .

Synopsis

  start-stream-encryption
--stream-name <value>
--encryption-type <value>
--key-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--stream-name (string)

The name of the stream for which to start encrypting records.

--encryption-type (string)

The encryption type to use. The only valid value is KMS .

Possible values:

• NONE

• KMS

--key-id (string)

The GUID for the customer-managed Amazon Web Services KMS key to use for encryption. This value can be a globally unique identifier, a fully specified Amazon Resource Name (ARN) to either an alias or a key, or an alias name prefixed by “alias/”.You can also use a master key owned by Kinesis Data Streams by specifying the alias aws/kinesis .

• Key ARN example: arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012

• Alias ARN example: arn:aws:kms:us-east-1:123456789012:alias/MyAliasName

• Globally unique key ID example: 12345678-1234-1234-1234-123456789012

• Alias name example: alias/MyAliasName

• Master key owned by Kinesis Data Streams: alias/aws/kinesis

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To enable data stream encryption

The following start-stream-encryption example enables server-side encryption for the specified stream, using the specified AWS KMS key.

aws kinesis start-stream-encryption \
    --encryption-type KMS \
    --key-id arn:aws:kms:us-west-2:012345678912:key/a3c4a7cd-728b-45dd-b334-4d3eb496e452 \
    --stream-name samplestream

This command produces no output.

Output
