Editor to share with you how to use CreateCommand to create a new cloud assistant command. I hope you will learn a lot after reading this article. Let's discuss it together.

CreateCommand

Description

You can create the following types of commands:

Bat script (RunBatScript) applicable to Windows instance

PowerShell script (RunPowerShellScript) applicable to Windows instance

Shell script (RunShellScript) applicable to Linux instance

You can set the maximum timeout when the command executes in the ECS instance by specifying the parameter TimeOut. After the command timeout, the cloud helper client will forcibly terminate the command process, that is, cancel the PID of the command.

For a single execution, after the timeout, the command's execution status (InvokeRecordStatus) for the specified ECS instance becomes Failed (execution failure).

For periodic execution:

The timeout for periodic execution is valid for each execution record.

After an execution timeout, the status of the execution record (InvokeRecordStatus) becomes the execution failure (Failed).

The timeout of the last execution does not affect the next execution.

You can specify the execution path for the command by specifying the parameter WorkingDir. For Linux instances, the default is under the administrator root user's home directory, specifically / root directory. For Windows instances, the default is the directory where the cloud helper client process resides, for example, C:\ ProgramData\ aliyun\ assist\ $(version).

You can create up to 100 cloud assistant commands in a region.
