AWS::SimSpaceWeaver::Simulation

Use the AWS::SimSpaceWeaver::Simulation resource to specify a simulation that AWS CloudFormation starts in the AWS Cloud, in your AWS account. In the resource properties section of your template, provide the name of an existing IAM role configured with the proper permissions, and the name of an existing Amazon S3 bucket. Your account must have permissions to read the Amazon S3 bucket. The Amazon S3 bucket must contain a valid schema. The schema must refer to simulation assets that are already uploaded to the AWS Cloud. For more information, see the detailed tutorial in the AWSSimSpace Weaver User Guide.

Specify a SnapshotS3Location to start a simulation from a snapshot instead of from a schema. When you start a simulation from a snapshot, SimSpace Weaver initializes the entity data in the State Fabric with data saved in the snapshot, starts the spatial and service apps that were running when the snapshot was created, and restores the clock to the appropriate tick. Your app zip files must be in the same location in Amazon S3 as they were in for the original simulation. You must start any custom apps separately. For more information about snapshots, see Snapshots in the AWSSimSpace Weaver User Guide.

  MaximumDuration: String
  Name: String
  RoleArn: String

    S3Location

Properties

MaximumDuration

The maximum running time of the simulation, specified as a number of minutes (m or M), hours (h or H), or days (d or D). The simulation stops when it reaches this limit. The maximum value is 14D, or its equivalent in the other units. The default value is 14D. A value equivalent to 0 makes the simulation immediately transition to STOPPING as soon as it reaches STARTED.

Required: No

Type: String

Minimum: 2

Maximum: 6

Update requires: Replacement

Name

The name of the simulation.

Required: Yes

Type: String

Minimum: 1

Maximum: 2048

Update requires: Replacement

RoleArn

The Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) role that the simulation assumes to perform actions. For more information about ARNs, see Amazon Resource Names (ARNs) in the AWS General Reference. For more information about IAM roles, see IAM roles in the AWS Identity and Access Management User Guide.

Required: Yes

Type: String

Update requires: Replacement

SchemaS3Location

The location of the simulation schema in Amazon Simple Storage Service (Amazon S3). For more information about Amazon S3, see the Amazon Simple Storage Service User Guide.

Provide a SchemaS3Location to start your simulation from a schema.

If you provide a SchemaS3Location then you can't provide a SnapshotS3Location.

Update requires: Replacement

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the name of the Simulation. For example, MyTestSimulation_22-12-15_12_00_00.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

DescribePayload: The JSON blob that the DescribeSimulation action returns.

Start a simulation with assets that you created with the app SDK scripts - version 1.12.x

The following example specifies a simulation resource in the AWS Cloud with assets that you created with the app SDK scripts (version 1.12.x). The version 1.12.x scripts upload your app zips and schema to separate buckets for each project. In this example, the create-project script used --name MyTestSimulation and uploaded to us-west-2. For more information, see the detailed tutorial in the AWS SimSpace Weaver User Guide.

Start a simulation from a snapshot

The following example starts a simulation from a snapshot instead of from a schema. The snapshot in this example was created from the simulation in the previous example. Note that the MaximumDuration setting isn't preserved in the snapshot. This simulation is a new simulation with a new MaximumDuration of 2 days.

We recommend that you make and use a copy of your original simulation's app role. The original simulation's app role could be deleted if you delete that simulation's AWS CloudFormation stack.
