Parameters

Map

No

Yes

Key-value pairs for custom parameters when the script contains them. For example, if the script content is `echo {{name}}`, specify `{"name":"Jack"}` using the Parameters property. The custom parameter automatically replaces the variable `name`, resulting in a new script that executes `echo Jack`.

  • Supports a maximum of 10 custom parameters.

  • Keys cannot be empty strings and support a maximum of 64 characters. Values can be empty strings.

  • The combined length of custom parameters and original script content cannot exceed 16 KB after Base64 encoding.

  • The set of custom parameter names must be a subset of the parameter set defined when creating the script.

  • For unspecified parameters, use an empty string.

Description

String

No

No

Script description.

Supports all character sets. The length cannot exceed 512 characters.

Timeout

Integer

No

Yes

The timeout for script execution.

Unit: seconds.

Default value: 60.

Timeouts occur if the script cannot run because of process issues, missing modules, or a missing Cloud Assistant Agent. After a timeout, the script process terminates forcibly.

ContentEncoding

String

No

Yes

The encoding method for the script content (CommandContent).

Values:

  • Base64 (default value): Base64 encoding.

  • PlainText: No encoding. Transmitted as plaintext.

Note

If you enter an incorrect value, the system treats it as Base64.

Name

String

No

No

Script name.

Supports all character sets. The length cannot exceed 128 characters.

WorkingDir

String

No

Yes

The working directory for the script on the ECS instance.

Default values:

  • Linux instances: /root

  • Windows instances: C:\Windows\System32\

CommandContent

String

Yes

Yes

The plaintext or Base64-encoded content of the script.

  • The script content cannot exceed 16 KB after Base64 encoding.

  • If `EnableParameter` is true, enable custom parameters in the script content. Write custom parameters within double curly braces (`{{}}`). Spaces and line feeds around the parameter name within the double curly braces (`{{}}`) are ignored.

  • The number of custom parameters cannot exceed 10. Custom parameter names can contain English letters, numbers, hyphens (-), and underscores (_). A single custom parameter name cannot exceed 64 characters.

Type

String

Yes

Yes

The language type of the O&M script.

Values:

  • RunBatScript: A Bat script for Windows instances.

  • RunPowerShellScript: A PowerShell script for Windows instances.

  • RunShellScript: A Shell script for Linux instances.

Frequency

String

No

No

The execution interval of the auto triggered task.

None

EnableParameter

Boolean

No

Yes

Indicates whether the script contains custom parameters.

Valid values:

  • true: Include custom parameters.

  • false (default): Do not include custom parameters.

InstanceIds

List

Yes

Yes

The list of ECS instance IDs.

Specify a maximum of 20 ECS instances. The ECS instances must be running.

KeepCommand

Boolean

No

No

Indicates whether to keep the script after execution.

Values:

  • true: Keep the script. You can execute it again using InvokeCommand. This consumes the quota for Cloud Assistant scripts.

  • false (default value): Do not keep the script. It is automatically deleted after execution and does not consume the quota for Cloud Assistant scripts.

Sync

Boolean

No

No

Indicates whether to use a synchronous call.

Values:

  • true: Synchronous call.

  • false: Asynchronous invocation.

Tags

List

No

Yes

Tags.

Supports a maximum of 20 tags. For more information, see Tags properties.

RunAgainOn

List

No

No

The stage to execute the command again.

None

WindowsPasswordName

String

No

No

The password name for the user who executes commands on Windows instances.

The length cannot exceed 255 characters.

If you want to execute commands on Windows instances as a non-default user (System), pass both the Username and this parameter. To reduce the threat of password leakage, host the plaintext password in the parameter repository of the orchestration service. Here, pass only the password name. For more information, see Encrypt parameters and Configure a regular user to execute Cloud Assistant commands.

Note

When you execute commands as the root user on Linux instances or the System user on Windows instances, do not pass this parameter.

RepeatMode

String

No

No

Sets the command execution method.

Values:

  • Once: Execute the command immediately.

  • Period: Execute the command at scheduled intervals. If this parameter is Period, you must also specify the Frequency parameter.

  • NextRebootOnly: Automatically execute the command when the instance starts next.

  • EveryReboot: Automatically execute the command every time the instance starts.

Default values:

  • If you do not specify the Frequency parameter, the default value is Once.

  • If you specify the Frequency parameter, the system processes it as Period, regardless of whether you set the parameter value.

Note:

  • You can call StopInvocation to stop pending or scheduled commands.

  • If this parameter is Period or EveryReboot, call DescribeInvocationResults and specify IncludeHistory=true to view the history of scheduled command executions.

Launcher

String

No

No

The bootstrap program for script execution.

The length cannot exceed 1 KB.

ResourceGroupId

String

No

No

The resource group ID for command execution.

If you specify this parameter:

ContainerName

String

No

No

Container name.

Note:

  • If you specify this parameter, Cloud Assistant executes the script within the specified container on the instance.

  • If you specify this parameter, it runs only on Linux instances with Cloud Assistant Agent version 2.2.3.344 or later.

  • If you specify this parameter, the Username and WorkingDir parameters you specified do not take effect. Commands execute only through the container's default user in the container's default working directory. For details, see Execute commands in containers using Cloud Assistant.

  • If you specify this parameter, only Shell scripts are supported in Linux containers. Do not specify the script content interpreter using commands such as #!/usr/bin/python at the beginning of the script. For details, see Execute commands in containers using Cloud Assistant.

ContainerId

String

No

No

Container ID.

Supports only 64-bit hexadecimal strings. You can specify the container runtime explicitly using prefixes such as docker://, containerd://, or cri-o://.

Note:

  • If you specify this parameter, Cloud Assistant executes the script within the specified container on the instance.

  • If you specify this parameter, it runs only on Linux instances with Cloud Assistant Agent version 2.2.3.344 or later.

  • If you specify this parameter, the Username and WorkingDir parameters you specified do not take effect. Commands execute only through the container's default user in the container's default working directory. For details, see Execute commands in containers using Cloud Assistant.

  • If you specify this parameter, only Shell scripts are supported in Linux containers. Do not specify the script content interpreter using commands such as #!/usr/bin/python at the beginning of the script. For details, see Execute commands in containers using Cloud Assistant.

Username

String

No

Yes

The username for executing commands on the ECS instance.

The length cannot exceed 255 characters.

  • Linux ECS instances execute commands as the root user by default.

  • Windows ECS instances execute commands as the System user by default.

You can also specify other existing users on the instance to execute commands. Executing Cloud Assistant commands as a regular user is more secure. For more information, see Configure a regular user to execute Cloud Assistant commands.

                ]
            }
        }
    }
}

After you successfully create the stack, update the configurations of the ECS instances where the command was executed. Configure the UpdatePolicy property during the update.

        ]
      },
      "UpdatePolicy": {
        "RollingUpdate": {

          "PauseTime": 10
        }
      }
    }
  }
}

Set MaxBatchSize to 2. Before the update, InstanceIds contains three ECS instances. After the update, InstanceIds contains five ECS instances. During the stack update, the original three instances undergo Upgrade/Downgrade in two batches (2 and 1). The system processes the original InstanceIds in the order they were provided. The two new instances execute the command simultaneously.
