The Cloud Assistant Agent is an agent that runs Cloud Assistant commands on Elastic Compute Service (ECS) instances. This topic describes how to upgrade and disable upgrades for the Cloud Assistant Agent.

Prerequisites

The Cloud Assistant Agent is installed. For more information, see Install the .

Automatic upgrade

The Cloud Assistant Agent runs the aliyun_assist_update upgrade process every 30 minutes. The process resides in the following path:
  • Windows instances: C:\ProgramData\aliyun\assist\${version}/aliyun_assist_update
  • Linux instances: /usr/local/share/aliyun-assist/${version}/aliyun_assist_update
Note {version} specifies the version number of the Cloud Assistant Agent.

Manual upgrade

If automatic upgrades do not take effect, you can run the ACS-ECS-UpdateAliyunAssist-linux.sh common command on Linux instances or the ACS-ECS-UpdateAliyunAssist-windows.ps1 common command on Windows instances to manually upgrade the Cloud Assistant Agent.

You can also download the latest installation package to upgrade the Cloud Assistant Agent. For example, to download the latest installation package in the RPM format and upgrade the Cloud Assistant Agent, run the following command. For information about the commands that are used for other installation packages, see Install the . 
wget "https://aliyun-client-assist.oss-accelerate.aliyuncs.com/linux/aliyun_assist_latest.rpm" && rpm -ivh --force aliyun_assist_latest.rpm

Manually disable upgrades

Use a configuration file to disable upgrades for the Cloud Assistant Agent

For Cloud Assistant Agent 2.2.1.140 or later on Linux instances and Cloud Assistant Agent 2.1.1.140 or later on Windows instances, you can disable upgrades by creating a configuration file in a specified path.

  • Disable the Cloud Assistant Agent from checking for upgrades on startup

    To disable a specific version of the Cloud Assistant Agent from checking for upgrades on startup, find the installation directory of the Cloud Assistant Agent version and create the disable_bootstrap_update file in the config folder. To disable all versions of the Cloud Assistant Agent on an instance from checking for upgrades on startup, find the general installation directory of all Cloud Assistant Agent versions and create the disable_bootstrap_update file in the config folder. You do not need to write data to the disable_bootstrap_update file.

    • If the instance on which the Cloud Assistant Agent is installed runs a Windows Server operating system, run the following commands in PowerShell. 
      # For example, run the following command to disable a specific version of the Cloud Assistant Agent from checking for upgrades on startup:
New-Item -Path C:\ProgramData\aliyun\assist\{version}\config\disable_bootstrap_update
# For example, run the following command to disable all versions of the Cloud Assistant Agent from checking for upgrades on startup:
New-Item -Path C:\ProgramData\aliyun\assist\config\disable_bootstrap_update
    • If the instance on which the Cloud Assistant Agent is installed runs a Linux operating system, run the following commands. 
      # For example, run the following command to disable a specific version of the Cloud Assistant Agent from checking for upgrades on startup:
touch /usr/local/share/aliyun-assist/{version}/config/disable_bootstrap_update
# For example, run the following command to disable all versions of the Cloud Assistant Agent from checking for upgrades on startup:
touch /usr/local/share/aliyun-assist/config/disable_bootstrap_update
    Note {version} specifies the version number of the Cloud Assistant Agent.
  • Disable the Cloud Assistant Agent from checking for updates

    To disable a specific version of the Cloud Assistant Agent from checking for updates, find the installation directory of the Cloud Assistant Agent version and create the disable_update file in the config folder.

      # For example, run the following command to disable a specific version of the Cloud Assistant Agent from checking for updates:
New-Item -Path C:\ProgramData\aliyun\assist\{version}\config\disable_update
# For example, run the following command to disable all versions of the Cloud Assistant Agent from checking for updates:
New-Item -Path C:\ProgramData\aliyun\assist\config\disable_update
    • If the instance on which the Cloud Assistant Agent is installed runs a Linux operating system, run the following commands. 
      # For example, run the following command to disable a specific version of the Cloud Assistant Agent from checking for updates:
touch /usr/local/share/aliyun-assist/{version}/config/disable_update
