start-stream-session
Description
This action initiates a new stream session and outputs connection information that clients can use to access the stream. A stream session refers to an instance of a stream that Amazon GameLift Streams transmits from the server to the end-user. A stream session runs on a compute resource, or stream capacity, that a stream group has allocated.
To start a new stream session, specify a stream group and application ID, along with the transport protocol and signal request settings to use with the stream. You must have associated at least one application to the stream group before starting a stream session, either when creating the stream group, or by using AssociateApplications .
For stream groups that have multiple locations, provide a set of locations ordered by priority by setting Locations . Amazon GameLift Streams will start a single stream session in the next available location. An application must be finished replicating in a remote location before the remote location can host a stream.
If the request is successful, Amazon GameLift Streams begins to prepare the stream. Amazon GameLift Streams assigns an Amazon Resource Name (ARN) value to the stream session resource and sets the status to ACTIVATING . During the stream preparation process, Amazon GameLift Streams queues the request and searches for available stream capacity to run the stream. This can result to one of the following:
- Amazon GameLift Streams identifies an available compute resource to run the application content and start the stream. When the stream is ready, the stream session’s status changes to
ACTIVEand includes stream connection information. Provide the connection information to the requesting client to join the stream session. - Amazon GameLift Streams doesn’t identify an available resource within a certain time, set by
ClientToken. In this case, Amazon GameLift Streams stops processing the request, and the stream session object status changes toERRORwith status reasonplacementTimeout.

Options
--additional-environment-variables (map)
A set of options that you can use to control the stream session runtime environment, expressed as a set of key-value pairs. You can use this to configure the application or stream session details. You can also provide custom environment variables that Amazon GameLift Streams passes to your game client.
Note
AdditionalEnvironmentVariables and AdditionalLaunchArgs have similar purposes. AdditionalEnvironmentVariables passes data using environment variables; while AdditionalLaunchArgs passes data using command-line arguments.

Shorthand Syntax:
KeyName1=string,KeyName2=string
JSON Syntax:
{"string": "string"
...}
--additional-launch-args (list)
A list of CLI arguments that are sent to the streaming server when a stream session launches. You can use this to configure the application or stream session details. You can also provide custom arguments that Amazon GameLift Streams passes to your game client.
AdditionalEnvironmentVariables and AdditionalLaunchArgs have similar purposes. AdditionalEnvironmentVariables passes data using environment variables; while AdditionalLaunchArgs passes data using command-line arguments.(string)

--application-identifier (string)
arn:aws:gameliftstreams:us-west-2:123456789012:application/a-9ZY8X7Wv6 or ID-a-9ZY8X7Wv6 .--client-token (string)
--connection-timeout-seconds (integer)
ACTIVE status. If no client connects before the timeout, Amazon GameLift Streams stops the stream session with status of TERMINATED . Default value is 120.--description (string)
--identifier (string)
The stream group to run this stream session with.
This value is an Amazon Resource Name (ARN) or ID that uniquely identifies the stream group resource. Format example: ARN-arn:aws:gameliftstreams:us-west-2:123456789012:streamgroup/sg-1AB2C3De4 or ID-sg-1AB2C3De4 .
--locations (list)
A list of locations, in order of priority, where you want Amazon GameLift Streams to start a stream from. Amazon GameLift Streams selects the location with the next available capacity to start a single stream session in. If this value is empty, Amazon GameLift Streams attempts to start a stream session in the primary location.
This value is A set of location names. For example, us-east-1 . For a complete list of locations that Amazon GameLift Streams supports, refer to Regions and quotas in the Amazon GameLift Streams Developer Guide .
(string)
Syntax:
"string" "string" ...
--protocol (string)
The data transport protocol to use for the stream session.
Possible values:
WebRTC
--session-length-seconds (integer)
--signal-request (string)
--user-id (string)
--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.
Global Options
--debug (boolean)
Turn on debug logging.
--endpoint-url (string)
Override command’s default URL with the given URL.
--no-verify-ssl (boolean)
By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.
--no-paginate (boolean)
Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.
--output (string)
The formatting style for command output.
- json
- text
- table
- yaml
- yaml-stream
--query (string)
A JMESPath query to use in filtering the response data.
--profile (string)
Use a specific profile from your credential file.
--region (string)
The region to use. Overrides config/env settings.
--version (string)
Display the version of this tool.
--color (string)
Turn on/off color output.
- on
- off
- auto
--no-sign-request (boolean)
Do not sign requests. Credentials will not be loaded if this argument is provided.
--ca-bundle (string)
The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.
--cli-read-timeout (int)
The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.
--cli-connect-timeout (int)
The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.
--cli-binary-format (string)
The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.
- base64
- raw-in-base64-out
--no-cli-pager (boolean)
Disable cli pager for output.
--cli-auto-prompt (boolean)
Automatically prompt for CLI input parameters.
--no-cli-auto-prompt (boolean)
Disable automatically prompt for CLI input parameters.
