Elastic Compute Service:Use Cloud Assistant to upload a file that does not exceed 24 KB in size to ECS instances

Prerequisites

• The target ECS instances are in the Running state.

• The file you want to upload does not exceed 24 KB in size.

  Important

  The file must not exceed 24 KB in size. To upload a file larger than 24 KB, use an alternative method. For more information, see Upload or download files.

Procedure

1. Go to ECS console - ECS Cloud Assistant.

2. In the top navigation bar, select the region and resource group of the resource that you want to manage.

3. On the ECS Instances tab, find the instance to which you want to upload a file and click Send File in the Actions column.

   • If the Cloud Assistant Status column shows Not Installed, install Cloud Assistant Agent on the instance as prompted.

   • If the Cloud Assistant Status column shows Abnormal, restart Cloud Assistant Agent. If the Cloud Assistant Agent version is earlier than 1.0.2.569 on a Linux instance or 1.0.0.149 on a Windows instance, manually install a later version. For more information, see Start, stop, or uninstall Cloud Assistant Agent or Install Cloud Assistant Agent.

     Note

     To send a file to multiple instances at once, click Send File in the upper-right corner of the ECS Cloud Assistant page instead. This lets you select multiple target instances for a single file sending task.

4. In the Send File panel, configure the following parameters in the Command Information section, and then click Run.

   Parameter	Description
   File	Required. Select an upload method and follow the on-screen instructions to upload the file.
   File Name	Required. Enter a name for the file. Important If Overwrite is turned off, the name must be unique in the destination path on the target ECS instances.
   Destination Path	Required. Specify an existing absolute path on the ECS instances where the file will be saved. Default values: Linux instances: /root Windows instances: C:\Users\Administrator\Documents
   File Description	Enter a description to help identify the file.
   User	Specify the user who owns the file. Note This parameter applies to Linux instances only.
   User Group	Specify the user group that owns the file. Note This parameter applies to Linux instances only.
   Permission	Set the file permissions using the same format as the chmod command. Default value: 0644. This means the file owner has read and write permissions, while users in the same group and all other users have read-only permissions. Note This parameter applies to Linux instances only.
   Overwrite	Specify whether to overwrite an existing file with the same name in the destination path. Turned off by default.
   Timeout	Set the timeout period for the file sending task, in seconds. If the task exceeds this duration, Cloud Assistant forcefully stops the task process. Valid values: 10 to 86400. Default value: 60.
   Tag	Add a tag to the file sending task for classification and management. Tag Key: the key of the tag. Tag Value: the value of the tag.
