Installing a Plug-in

If container protection is enabled and you want to use the image blocking function, install the Docker plug-in by following the instructions provided in this section.

Installing a Plug-in

Log in to the management console.
In the upper left corner of the page, select a region, click , and choose Security & Compliance > HSS.
In the navigation pane on the left, choose Installation & Configuration > Plug-in Settings. Click Plug-In Installation Guide. In the slide-out panel, copy the commands in the Installation Commands section.
Remotely log in to the server where the plug-in is to be installed as the root user.
- Log in to the ECS console, locate the target server, and click Remote Login in the Operation column to log in to the server. For details, see Login Using VNC.
- 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 install the plug-in on the server as user root.
Run the following command to access the /tmp directory:
```
cd /tmp/
```

Create linux-host-list.txt, which will contain the server private IP addresses where the agent is to be installed:

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

Press Enter to save the IP address. Run the cat linux-host-list.txt command to verify the IP addresses have been added.
Copy the batch installation commands to the command terminal and press Enter.

If the installation package cannot be downloaded, check to ensure the DNS can resolve the domain name in the installation commands.
If remote_install finished. [OK] is displayed, the installation is successful. Wait for 3 to 5 minutes and check the Docker plug-in status of the panel server.
