# StartBulkDeployment


Deploys multiple groups in one operation. This action starts the bulk deployment of a specified set of group versions. Each group version deployment is triggered with an adaptive rate that has a fixed upper limit. We recommend that you include an `X-Amzn-Client-Token` token in every `StartBulkDeployment` request. These requests are idempotent with respect to the token and the request parameters. 

URI: `POST /greengrass/bulk/deployments`

Produces: application/json

## CLI:


```
aws greengrass start-bulk-deployment \
  [--input-file-uri <value>] \
  [--execution-role-arn <value>] \
  [--tags <value>] \
  [--amzn-client-token <value>]  \
  [--cli-input-json <value>] \
  [--generate-cli-skeleton]
```

schema:    
StartBulkDeploymentRequest  
Information about a bulk deployment. You cannot start a new bulk deployment while another one is still running or in a non-terminal state.  
type: object  
required: ["InputFileUri", "ExecutionRoleArn"]  
InputFileUri  
The URI of the input file in the S3 bucket. The execution role must have `getObject` permissions on this bucket to access the input file. The input file is a JSON-serialized, line-delimited file with UTF-8 encoding that provides a list of group and version IDs and the deployment type. This file must be less than 100 MB. Currently, AWS IoT Greengrass supports only `NewDeployment` deployment types.   

```
{"GroupId":"groupId1", "GroupVersionId":"groupVersionId1", "DeploymentType":"NewDeployment"}
{"GroupId":"groupId2", "GroupVersionId":"groupVersionId2", "DeploymentType":"NewDeployment"}
{"GroupId":"groupId3", "GroupVersionId":"groupVersionId3", "DeploymentType":"NewDeployment"}
...
```
For more information, including the input file format, see [Create Bulk Deployments For Groups](https://docs.aws.amazon.com/greengrass/latest/developerguide/bulk-deploy-cli.html).  
type: string  
ExecutionRoleArn  
The ARN of the execution role to associate with the bulk deployment operation. This IAM role must allow the `greengrass:CreateDeployment` action for all group versions that are listed in the input file. This IAM role must have access to the S3 bucket that contains the input file.  
type: string  
tags  
The resource tags.  
type: object  
additionalProperties: The key-value pair for the resource tag. Type: string

[**X-Amzn-Client-Token**](parameters-clienttoken.md)
