Creating a Service

NOTE:

To ensure the created Service on a platinum instance of version v3 can be accessed, Edge DNS should be enabled for the containerized application that need to access the Service, and edgemesh should be installed on both the node initiating the access request and the node to be accessed.

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 List. On the page displayed, click Create Service in the upper right corner.
3. Set the parameters.
   • Service Name: Enter a Service name.
   • Application: Select the application that the Service is bound to.
   • Port Settings
     • Access Port: indicates the port used to access the containerized application.
     • Container Port: indicates the port on which the containerized application listens.
     • Protocol: Specify the protocol that will be used to access the workload. Select HTTP or TCP.

A traffic policy defines how service traffic is forwarded to multiple application instances.

3. On the page displayed, select a traffic policy type.
   Currently, the following traffic policy types are supported:

   • Load Balancing Algorithm: Two forwarding modes, that is, ROUND_ROBIN and RANDOM, are supported.
   • Session persistence: Three HTTP header-based forwarding modes, that is, Cookie, User-Agent, and Custom, are supported.
