AWS CLI Command Reference

[ aws . iotthingsgraph ]

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. 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.

--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.

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 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",
        "status": "NOT_DEPLOYED",
        "target": "CLOUD",
