This article is about how to trigger a cloud helper command for one or more ECS instances. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

InvokeCommand

Description

When you use this interface, note that:

In an Ali cloud region, you can run cloud assistant commands up to 500 times a day.

The network type of the target instance must be a private network VPC.

The status of the target instance must be Running.

The target instance must be pre-installed with the Cloud Assistant client.

When executing a command of type PowerShell, you need to ensure that the target ECS Windows instance has been configured with the PowerShell module.

For a single execution (Timed=False), the command is executed only once.

For periodic execution (Timed=True), the cloud helper will be executed regularly according to the time and frequency specified by the parameter Frequency. The result of the last execution does not have any impact on the next execution.

The time benchmark for cycle execution is UTC + 08:00, and this time is based on the system time of the instance. You need to make sure that the time or time zone of your ECS instance is the same as your expected time.

For more information about time zone, please see modify ECS Linux instance time zone and set NTP service for Linux instance, and synchronize Windows instance clock for Windows instance.

You can select multiple ECS instances. If one of the instances does not meet the execution conditions, you need to re-select them.

The execution of the command may not be executed due to the abnormal status of the target instance, network exception or cloud helper client exception, and no execution information will be generated when it cannot be executed.
