Adding a Proxy to a Host Cluster for CodeArts Deploy

Prerequisites

• A host cluster is available, and you have the permission to add hosts to the cluster.
• A host bound with a public IP address is available. (If you do not have a host, purchase one by referring to Purchasing an ECS.)

Adding a Target Host

1. Go to the Basic Resources page.
2. Click the name of the desired cluster to go to the Target Hosts tab page.
3. Click Add Host and select Adding IP for Add Hosts by.
4. Select Proxy for Host Connection Mode to add a proxy host. Enter the following information and click OK.

   Table 1 Parameters of the proxy host (Linux)

   Parameter	Mandatory	Description
   Host Name	Yes	Enter a user-defined proxy host name. Enter 3 to 128 characters. Use digits, letters, hyphens (-), underscores (_), and periods (.).
   IP	Yes	Enter the public IP address bound to the proxy host. IPv4 or IPv6 addresses are supported.
   OS	Yes	The default value is the OS of the current host cluster and cannot be changed. Configure the target host by referring to Configuring a Linux Host to ensure successful connectivity verification.
   Authorization	Yes	Select a password or key for authentication as required. If you select Password, the Username and Password are displayed. Take ECS as an example. Enter the ECS username and password. If you select Key, the Username and Key are displayed. For details about how to generate and obtain a key, see Obtaining the Linux key.
   SSH Port	Yes	Port 22 is recommended. You may customize the port number.
   Install AOM ICAgent for metric monitoring, log query, and alarm functions on Huawei Cloud Linux hosts. Configure an agency before installation.	No	If the checkbox is selected, you can install and use AOM-ICAgent on your hosts for free for metric monitoring, log query, and alarm functions. ICAgent applies only to Huawei Cloud Linux hosts. Before installing ICAgent, configure an agency by referring to Creating and Using an Agency.

   Table 2 Parameters of the proxy host (Windows)

   Parameter	Mandatory	Description
   Host Name	Yes	Enter a user-defined proxy host name. Enter 3 to 128 characters. Use digits, letters, hyphens (-), underscores (_), and periods (.).
   IP	Yes	Enter the public IP address bound to the proxy host. IPv4 or IPv6 addresses are supported.
   OS	Yes	The default value is the OS of the current host cluster and cannot be changed. Configure the target host by referring to Configuring the Host Running Windows to ensure successful connectivity verification.
   Authorization	Yes	Windows proxies support only password authentication. Take ECS as an example. Enter the ECS username and password.
   Winrm Port	Yes	Port 5986 is recommended. You may customize the port number.

5. To add your Huawei Cloud ECS as the target host or proxy host, click Add Host, and select Importing ECS for Add Hosts by.
   CAUTION:

   You should meet the following requirements to import purchased ECS:

   • ECS is running.
   • ECS and host cluster have the same OS.
   • Proxy host has a public IP (proxy mode) when using official resource pool.
   • Host is not the imported target host.

   In the proxy mode, you need to configure the proxy host before using the target host.

6. Verify the host connectivity.

   After the host is added, the system automatically verifies the connectivity. If the connectivity verification fails, click Failed and rectify the fault based on the failure cause displayed in the dialog box or click View Solution.

Configuring a Linux Proxy

Required Resources

You have configured the following resources in a Virtual Private Cloud (VPC):

Configuring a Windows Proxy

Required Resources

• A Windows host is available.
• The network connection between the proxy and hosts is normal.

Procedure

1. Log in to the proxy, open PowerShell, and run the netsh command. Replace the parameters based on the parameter descriptions.

   netsh interface portproxy add v4tov4 listenaddress=${proxy_ip}  listenport=${proxy_port}  connectaddress=${host_ip}  connectport=${host_port}

   For IPv6 hosts, replace v4tov4 in the following command with v6tov6.

   Table 4 Parameters

   Parameter	Description
   ${proxy_ip}	Private IP address of the proxy.
   ${proxy_port}	Listening port of the proxy, for example, 54.
   ${host_ip}	Private IP address of the host.
   ${host_port}	Port of the host. Generally, the port is 5986.

   

2. Enable the proxy listening port, that is, ${proxy_port} in the preceding command. For details, see Configuring a Security Group.
