This article mainly introduces the method of executing a command in one or more instances after creating a cloud assistant command, which can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Execute a command

After you create a cloud helper command, you can execute the command in one or more instances. The execution status and results of multiple instances do not affect each other, and you can also set the execution cycle for the command.

Use restriction

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

You can select up to 50 instances at a time.

The state of the target instance must be in Running.

The target instance must have the Cloud Assistant client installed.

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

The interval set by the periodic cloud assistant command cannot be less than 10 seconds.

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.

Execute a command

The steps to execute the command on the administrative console are as follows:

Log in to the ECS Management console.

On the left navigation bar, click the Cloud Assistant.
