Procedure

1. Log in to the management console.
2. Click in the upper left corner of the page, select a region, and choose Security > Host Security Service.
3. In the navigation tree on the left, choose Installation & Configuration and click the Plug-in Settings > Docker plug-in tab. Click Plug-in upgrade guide, obtain the upgrade commands from the slide-out panel, and click Copy.
4. Remotely log in to the server where the plug-in is to be upgraded as the root user.
   • You can log in to the ECS management console and click Remote Login in the ECS list.
   • If your server has an EIP bound, you can also use a remote management tool, such as PuTTY or Xshell, to log in to the server and upgrade the plug-in on the server as user root.

5. Run the following command to access the /tmp directory:

   cd /tmp/

6. Create linux-host-list.txt, which will contain the server private IP addresses where the plug-in is to be upgraded:

   Command syntax:

   echo 127.8.8.8 22 root rootPassword >> linux-host-list.txt

   Or echo 127.8.8.8 22 user userPassword rootPassword >> linux-host-list.txt

   To specify multiple IP addresses, write multiple commands, each in a separate line.

   Example:

   echo 127.8.8.1 22 root rootPassword >> linux-host-list.txt
   echo 127.8.8.2 22 user userPassword rootPassword >> linux-host-list.txt
   echo 127.8.8.3 22 root rootPassword >> linux-host-list.txt

7. Press Enter to save the IP address. Run the cat linux-host-list.txt command to verify the IP addresses have been added.
8. Copy the batch upgrade commands to the command box and press Enter. The upgrade starts automatically.
9. If remote_upgrade finished. [OK] is displayed, the upgrade is successful. Wait for 3 to 5 minutes and choose Installation & Configuration and click the Plug-in Settings tab to check the Docker plug-in status of the panel server.
