Running scripts from Amazon S3

Run a shell script from Amazon S3

1. Open the Amazon Systems Manager console at https://console.amazonaws.cn/systems-manager/.

2. In the navigation pane, choose Run Command.

   -or-

   If the Amazon Systems Manager home page opens first, choose the menu icon ( ) to open the navigation pane, and then choose Run Command.

3. Choose Run command.

4. In the Command document list, choose AWS-RunRemoteScript.

5. In Command parameters, do the following:

   • In Source Type, select S3.

   • In the Source Info text box, enter the required information to access the source in the following format. Replace each example resource placeholder with your own information.

     Note

     Replace https://s3.aws-api-domain with the URL for your bucket. You can copy your bucket URL in Amazon S3 on the Objects tab.

     {"path":"https://s3.aws-api-domain/path to script"}

     The following is an example.

     {"path":"https://mytestbucket.s3.us-west-2.amazonaws.com/scripts/shell/helloWorld.sh"}

   • In the Command Line field, enter parameters for the script execution. Here is an example.

     helloWorld.sh argument-1 argument-2

   • (Optional) In the Working Directory field, enter the name of a directory on the node where you want to download and run the script.

   • (Optional) In Execution Timeout, specify the number of seconds for the system to wait before failing the script command execution.

6. In the Targets section, choose the managed nodes on which you want to run this operation by specifying tags, selecting instances or edge devices manually, or specifying a resource group.

   Tip

   If a managed node you expect to see isn't listed, see Troubleshooting managed node availability for troubleshooting tips.

7. For Other parameters:

   • For Comment, enter information about this command.

   • For Timeout (seconds), specify the number of seconds for the system to wait before failing the overall command execution.

8. For Rate control:

   • For Concurrency, specify either a number or a percentage of managed nodes on which to run the command at the same time.

     Note

     If you selected targets by specifying tags applied to managed nodes or by specifying Amazon resource groups, and you aren't certain how many managed nodes are targeted, then restrict the number of targets that can run the document at the same time by specifying a percentage.

   • For Error threshold, specify when to stop running the command on other managed nodes after it fails on either a number or a percentage of nodes. For example, if you specify three errors, then Systems Manager stops sending the command when the fourth error is received. Managed nodes still processing the command might also send errors.

9. (Optional) For Output options, to save the command output to a file, select the Write command output to an S3 bucket box. Enter the bucket and prefix (folder) names in the boxes.

   Note

   The S3 permissions that grant the ability to write the data to an S3 bucket are those of the instance profile (for EC2 instances) or IAM service role (hybrid-activated machines) assigned to the instance, not those of the IAM user performing this task. For more information, see Configure instance permissions for Systems Manager or Create an IAM service role for a hybrid environment. In addition, if the specified S3 bucket is in a different Amazon Web Services account, make sure that the instance profile or IAM service role associated with the managed node has the necessary permissions to write to that bucket.

10. In the SNS notifications section, if you want notifications sent about the status of the command execution, select the Enable SNS notifications check box.

    For more information about configuring Amazon SNS notifications for Run Command, see Monitoring Systems Manager status changes using Amazon SNS notifications.

11. Choose Run.

1. Install and configure the Amazon Command Line Interface (Amazon CLI), if you haven't already.

   For information, see Installing or updating the latest version of the Amazon CLI.

2. Run the following command. Replace each example resource placeholder with your own information.

   Note

   Replace https://s3.aws-api-domain with the URL for your bucket. You can copy your bucket URL in Amazon S3 on the Objects tab.
