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

Prerequisites

• The ECS instances to which you want to upload a file are in the Running (Running) state.

• The file cannot exceed 24 KB in size.

  Important

  To upload a file whose size is larger than 24 KB, use other methods. For more information, see Upload or download files.

Procedure

1. Log on to the ECS console.

2. In the left-side navigation pane, choose Maintenance & Monitoring > Cloud Assistant.

3. In the top navigation bar, select the region and resource group to which the resource belongs.

4. In the instance list of the ECS Instances tab, find the instance to which you want to upload a file and click Send File in the Actions column.

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

   • If Abnormal is displayed in the Cloud Assistant Status column, 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 of Cloud Assistant Agent. For more information, see Start, stop, or uninstall Cloud Assistant Agent or Install Cloud Assistant Agent.
