Options¶

--instance-ids (list)

The instance IDs where the command should run. You can specify a maximum of 50 IDs. If you prefer not to list individual instance IDs, you can instead send commands to a fleet of instances using the Targets parameter, which accepts EC2 tags. For more information about how to use targets, see Using targets and rate controls to send commands to a fleet in the AWS Systems Manager User Guide .

(string)

Syntax:

"string" "string" ...

--targets (list)

(Optional) An array of search criteria that targets instances using a Key,Value combination that you specify. Targets is required if you don’t provide one or more instance IDs in the call. For more information about how to use targets, see Sending commands to a fleet in the AWS Systems Manager User Guide .

(structure)

An array of search criteria that targets instances using a Key,Value combination that you specify.

Supported formats include the following.

``Key=InstanceIds,Values=*instance-id-1* ,*instance-id-2* ,*instance-id-3* ``

``Key=tag:my-tag-key ,Values=*my-tag-value-1* ,*my-tag-value-2* ``

``Key=tag-key,Values=*my-tag-key-1* ,*my-tag-key-2* ``

(Maintenance window targets only) ``Key=resource-groups:Name,Values=*resource-group-name* ``

(Maintenance window targets only) ``Key=resource-groups:ResourceTypeFilters,Values=*resource-type-1* ,*resource-type-2* ``

For example:

Key=InstanceIds,Values=i-02573cafcfEXAMPLE,i-0471e04240EXAMPLE,i-07782c72faEXAMPLE

Key=tag:CostCenter,Values=CostCenter1,CostCenter2,CostCenter3

Key=tag-key,Values=Name,Instance-Type,CostCenter

(Maintenance window targets only) Key=resource-groups:Name,Values=ProductionResourceGroup This example demonstrates how to target all resources in the resource group ProductionResourceGroup in your maintenance window.

(Maintenance window targets only) ``Key=resource-groups:ResourceTypeFilters,Values=*AWS::EC2::INSTANCE* ,*AWS::EC2::VPC* `` This example demonstrates how to target only EC2 instances and VPCs in your maintenance window.

(State Manager association targets only) Key=InstanceIds,Values=* This example demonstrates how to target all managed instances in the AWS Region where the association was created.

For information about how to send commands that target instances using Key,Value parameters, see Targeting multiple instances in the AWS Systems Manager User Guide .

Key -> (string)

User-defined criteria for sending commands that target instances that meet the criteria.

Values -> (list)

User-defined criteria that maps to Key . For example, if you specified tag:ServerRole , you could specify value:WebServer to run a command on instances that include EC2 tags of ServerRole,WebServer .

(string)

Shorthand Syntax:

Key=string,Values=string,string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Values": ["string", ...]
  }
  ...
]

--document-name (string)

Required. The name of the Systems Manager document to run. This can be a public document or a custom document.

--document-version (string)

The SSM document version to use in the request. You can specify $DEFAULT, $LATEST, or a specific version number. If you run commands by using the AWS CLI, then you must escape the first two options by using a backslash. If you specify a version number, then you don’t need to use the backslash. For example:

—document-version “$DEFAULT”

–document-version “$LATEST”

—document-version “3”

--document-hash (string)

The Sha256 or Sha1 hash created by the system when the document was created.

Note

Sha1 hashes have been deprecated.

--document-hash-type (string)

Sha256 or Sha1.

Note

Sha1 hashes have been deprecated.

Possible values:

Sha256

Sha1

--timeout-seconds (integer)

If this time is reached and the command has not already started running, it will not run.

--comment (string)

User-specified information about the command, such as a brief description of what the command should do.

--parameters (map)

The required and optional parameters specified in the document being run.

key -> (string)

value -> (list)

(string)

Shorthand Syntax:

KeyName1=string,string,KeyName2=string,string

JSON Syntax:

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

--output-s3-region (string)

(Deprecated) You can no longer specify this parameter. The system ignores it. Instead, Systems Manager automatically determines the Region of the S3 bucket.

--output-s3-bucket-name (string)

The name of the S3 bucket where command execution responses should be stored.

--output-s3-key-prefix (string)

The directory structure within the S3 bucket where the responses should be stored.

--max-concurrency (string)

(Optional) The maximum number of instances that are allowed to run the command at the same time. You can specify a number such as 10 or a percentage such as 10%. The default value is 50. For more information about how to use MaxConcurrency, see Using concurrency controls in the AWS Systems Manager User Guide .

--max-errors (string)

The maximum number of errors allowed without the command failing. When the command fails one more time beyond the value of MaxErrors, the systems stops sending the command to additional targets. You can specify a number like 10 or a percentage like 10%. The default value is 0. For more information about how to use MaxErrors, see Using error controls in the AWS Systems Manager User Guide .

--service-role-arn (string)

The ARN of the IAM service role to use to publish Amazon Simple Notification Service (Amazon SNS) notifications for Run Command commands.

--notification-config (structure)

Configurations for sending notifications.

NotificationArn -> (string)

An Amazon Resource Name (ARN) for an Amazon Simple Notification Service (Amazon SNS) topic. Run Command pushes notifications about command status changes to this topic.

NotificationEvents -> (list)

The different events for which you can receive notifications. These events include the following: All (events), InProgress, Success, TimedOut, Cancelled, Failed. To learn more about these events, see Monitoring Systems Manager status changes using Amazon SNS notifications in the AWS Systems Manager User Guide .

(string)

NotificationType -> (string)

Command: Receive notification when the status of a command changes. Invocation: For commands sent to multiple instances, receive notification on a per-instance basis when the status of a command changes.

Shorthand Syntax:

NotificationArn=string,NotificationEvents=string,string,NotificationType=string

JSON Syntax:

{
  "NotificationArn": "string",
  "NotificationEvents": ["All"|"InProgress"|"Success"|"TimedOut"|"Cancelled"|"Failed", ...],
  "NotificationType": "Command"|"Invocation"
}

--cloud-watch-output-config (structure)

Enables Systems Manager to send Run Command output to Amazon CloudWatch Logs.

CloudWatchLogGroupName -> (string)

The name of the CloudWatch log group where you want to send command output. If you don’t specify a group name, Systems Manager automatically creates a log group for you. The log group uses the following naming format: aws/ssm/SystemsManagerDocumentName .

CloudWatchOutputEnabled -> (boolean)

Enables Systems Manager to send command output to CloudWatch Logs.

Shorthand Syntax:

CloudWatchLogGroupName=string,CloudWatchOutputEnabled=boolean

JSON Syntax:

{
  "CloudWatchLogGroupName": "string",
  "CloudWatchOutputEnabled": true|false
}

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Example 1: To run a command on one or more remote instances

The following send-command example runs an echo command on a target instance.

aws ssm send-command \
    --document-name "AWS-RunShellScript" \
    --parameters 'commands=["echo HelloWorld"]' \
    --targets "Key=instanceids,Values=i-1234567890abcdef0" \
    --comment "echo HelloWorld"

Output:

{
    "Command": {
        "CommandId": "92853adf-ba41-4cd6-9a88-142d1EXAMPLE",
        "DocumentName": "AWS-RunShellScript",

        "MaxErrors": "0",
        "TargetCount": 1,
        "CompletedCount": 0,
        "ErrorCount": 0,
        "DeliveryTimedOutCount": 0,
        "ServiceRole": "",
        "NotificationConfig": {

The following send-command example retrieves the IP information about an instance.

aws ssm send-command \
    --instance-ids "i-1234567890abcdef0" \
    --document-name "AWS-RunShellScript" \
    --comment "IP config" \
    --parameters "commands=ifconfig"
