Update Session Manager Preferences (AWS CLI)

The following procedure describes how to use the AWS CLI and the update-document command to make changes to the Session Manager preferences for your account in the selected AWS Region. Use Session Manager preferences to specify options for logging session data in an Amazon S3 bucket or Amazon CloudWatch Logs log group. You can also use Session Manager preferences to encrypt your session data.

To update Session Manager preferences (AWS CLI)

  1. Create a JSON file on your local machine with a name such as SessionManagerRunShell.json, and then paste the following content into it:

    { "schemaVersion": "1.0", "description": "Document to hold regional settings for Session Manager", "sessionType": "Standard_Stream", "inputs": { "s3BucketName": "", "s3KeyPrefix": "", "s3EncryptionEnabled": true, "cloudWatchLogGroupName": "", "cloudWatchEncryptionEnabled": true } }
  2. Specify where you want to send session data. You can specify an S3 bucket name (with an optional prefix) or a CloudWatch Logs log group name. For example:

    { "schemaVersion": "1.0", "description": "Document to hold regional settings for Session Manager", "sessionType": "Standard_Stream", "inputs": { "s3BucketName": "MyBucketName", "s3KeyPrefix": "MyBucketPrefix", "s3EncryptionEnabled": true, "cloudWatchLogGroupName": "MyLogGroupName", "cloudWatchEncryptionEnabled": true } }

    Note

    If you do not want to encrypt the log data, change "true" to "false".

    If you aren't sending logs to either an S3 bucket or a CloudWatch Logs log group, you can delete the lines for those options. Make sure the last line in the "inputs" section does not end with a comma.

  3. Save the file.

  4. In the directory where you created the JSON file, run the following command:

    aws ssm update-document --name "SSM-SessionManagerRunShell" --content "file://SessionManagerRunShell.json" --document-version "\$LATEST"

    Important

    Be sure to include file:// before the file name. It is required in this command.

    If successful, the command returns output similar to the following:

    { "DocumentDescription": { "Status": "Updating", "Hash": "ce4fd0a2ab9b0fae759004ba603174c3ec2231f21a81db8690a33eb66EXAMPLE", "Name": "SSM-SessionManagerRunShell", "Tags": [], "DocumentType": "Session", "PlatformTypes": [ "Windows", "Linux" ], "DocumentVersion": "2", "HashType": "Sha256", "CreatedDate": 1537206341.565, "Owner": "111122223333", "SchemaVersion": "1.0", "DefaultVersion": "1", "DocumentFormat": "JSON", "LatestVersion": "2" } }
