Gateways

Creating a Gateway

To ensure that the created gateway on a platinum instance of version v3 can be accessed, edgemesh-gateway should be installed on the node where the gateway application is located.

A gateway enables unified entry, traffic management, security, and service isolation. You can create a gateway as follows:

1. Log in to the IEF console, and click Switch Instance on the Dashboard page to select a platinum service instance.
2. In the navigation pane, choose Application Mesh > Service Gateway. On the page displayed, click Create Gateway in the upper right corner.
3. Specify the gateway information.
   • Gateway Name: Enter a gateway name.
   • Application: Select the gateway application.
     

     Select the gateway application for platinum instances of version v2. For platinum instances of version v3, skip this step if edgemesh-gateway has been installed on the edge node where the gateway application is located.

   • Port Configuration

     Port: Enter the port number used by the gateway to access backend applications.

     Protocol: Select the protocol used by the gateway to access backend applications. HTTP and HTTPS are supported. If you select HTTPS, configure Protocol Version, Certificate Secret, and Cipher Suite. If you select HTTP, configure domain names.

     Protocol Version: Select a protocol version.

     Certificate Secret: Select an SSL certificate. Public key files are public, and private key files are obtained by applying for certificates. Both are provided by yourself.

     

     You can add the SSL certificate secret required for configuring the HTTPS protocol only here.

     Cipher Suite: Select cipher suites contained in the SSL certificate and cipher suites supported by the client.

     Domain Names: Enter the domain names that can be accessed. Regular expression matching is supported. For example, * indicates all domain names.

   • HTTP Routes
     • URI Match Type: Prefix match, Exact match, and Regular expression are supported.
     • URI: Enter a URI.
     • Target Service: Select the Service to which the rule matches, that is, the Service to which the traffic from the URI is forwarded.
     • Service Access Port: Select the port used by the Service to access the application.
