| <p>The grpc_cli tool is a tool used by the gRPC ecosystem to debug services. It can be obtained under the premise that [reflection service] (<a href="https://github.com/grpc/grpc/blob/master/doc/server-reflection.md">https://github.com/grpc/grpc/blob/master/doc/server-reflection.md</a>) is enabled on the server Go to the service&rsquo;s proto file, service name, method name, parameter list, and initiate a gRPC call.</p> |
| <p>The Triple protocol is compatible with the gRPC ecosystem, and the gRPC reflection service is enabled by default, so you can directly use grpc_cli to debug the triple service.</p> |

| <h2 id="1-framework-configuration">1. Framework configuration</h2> |
| <p>The Dubbo-go framework needs to rely on configuration to start. Configuration contains the various capabilities that a developer wishes to use with the framework.</p> |
| <h3 id="configuration-format">Configuration format</h3> |
| <p>yaml</p> |
| <h3 id="configuration-path">Configuration path</h3> |
| <p>Load framework configuration from <code>../conf/dubbogo.yaml</code> by default</p> |
| <p>You can modify the configuration file path by specifying the environment variable: DUBBO_GO_CONFIG_PATH=$(your_config_path)/dubbogo.yaml.</p> |

| <p>When the framework is loaded, any form of configuration will be parsed into RootConfig and loaded in the RootConfig.Init method.</p> |
| <h2 id="2-configuration-api">2. Configuration API</h2> |
| <p>Developers can start the framework by building configurations in the form of an API. This method is more suitable for the situation where dubbo-go is introduced as a third-party component.</p> |
| <h2 id="3-configuration-center">3. Configuration Center</h2> |
| <p>Developers can place configurations in the configuration center to facilitate configuration management and modification.</p></description></item></channel></rss> |
