Configuring the Port for Other Components in the Environment to Access the Component

Scenarios

If a component needs to be called by other services or monitoring or O&M tools in the microservice cluster, you must configure ports to ensure that the component can be accessed by external systems.

This section describes how to configure the ports for other components in the environment to access the component. After configuration, log in to the cluster node and run the curl command to access the component.

Constraints

This function is available only in CN North-Beijing4, CN South-Guangzhou, CN East-Shanghai1, ME-Riyadh, TR-Istanbul, AF-Johannesburg, LA-Mexico City2, and LA-Sao Paulo1.

Prerequisites

You have created an application and component.
