create-system-instance

Description

Creates a system instance.

This action validates the system instance, prepares the deployment-related resources. For Greengrass deployments, it updates the Greengrass group that is specified by the greengrassGroupName parameter. It also adds a file to the S3 bucket specified by the s3BucketName parameter. You need to call DeploySystemInstance after running this action.

For Greengrass deployments, since this action modifies and adds resources to a Greengrass group and an S3 bucket on the caller’s behalf, the calling identity must have write permissions to both the specified Greengrass group and S3 bucket. Otherwise, the call will fail with an authorization error.

For cloud deployments, this action requires a flowActionsRoleArn value. This is an IAM role that has permissions to access AWS services, such as AWS Lambda and AWS IoT, that the flow uses when it executes.

If the definition document doesn’t specify a version of the user’s namespace, the latest version will be used by default.

Options

--tags (list)

Metadata, consisting of key-value pairs, that can be used to categorize your system instances.

(structure)

Metadata assigned to an AWS IoT Things Graph resource consisting of a key-value pair.

key -> (string)

The required name of the tag. The string value can be from 1 to 128 Unicode characters in length.

value -> (string)

The optional value of the tag. The string value can be from 1 to 256 Unicode characters in length.

Shorthand Syntax:

key=string,value=string ...

JSON Syntax:

[
  {
    "key": "string",
    "value": "string"
  }
  ...
]

--definition (structure)

A document that defines an entity.

language -> (string)

The language used to define the entity. GRAPHQL is the only valid value.

text -> (string)

The GraphQL text that defines the entity.

Shorthand Syntax:

language=string,text=string

JSON Syntax:

{
  "language": "GRAPHQL",
  "text": "string"
}

--target (string)

The target type of the deployment. Valid values are GREENGRASS and CLOUD .

Possible values:

• GREENGRASS

• CLOUD

--greengrass-group-name (string)

The name of the Greengrass group where the system instance will be deployed. This value is required if the value of the target parameter is GREENGRASS .

--s3-bucket-name (string)

The name of the Amazon Simple Storage Service bucket that will be used to store and deploy the system instance’s resource file. This value is required if the value of the target parameter is GREENGRASS .

--metrics-configuration (structure)

An object that specifies whether cloud metrics are collected in a deployment and, if so, what role is used to collect metrics.

cloudMetricEnabled -> (boolean)

A Boolean that specifies whether cloud metrics are collected.

metricRuleRoleArn -> (string)

The ARN of the role that is used to collect cloud metrics.

Shorthand Syntax:

cloudMetricEnabled=boolean,metricRuleRoleArn=string

JSON Syntax:

{
  "cloudMetricEnabled": true|false,
  "metricRuleRoleArn": "string"
}

--flow-actions-role-arn (string)

The ARN of the IAM role that AWS IoT Things Graph will assume when it executes the flow. This role must have read and write access to AWS Lambda and AWS IoT and any other AWS services that the flow uses when it executes. This value is required if the value of the target parameter is CLOUD .

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To create a system instance

The following create-system-instance example creates a system instance. The value of MySystemInstanceDefinition is the GraphQL that models the system instance.

aws iotthingsgraph create-system-instance -\
    -definition language=GRAPHQL,text="MySystemInstanceDefinition" \
    --target CLOUD \
    --flow-actions-role-arn myRoleARN

Output:

{
    "summary": {
        "id": "urn:tdm:us-west-2/123456789012/default:Deployment:Room218",
        "arn": "arn:aws:iotthingsgraph:us-west-2:123456789012:Deployment/default/Room218",

    }
}
