Registering Plugin Components

A Waypoint plugin is just a Go binary; if you look at main.go you will see the main function. The sdk.Main function sets up the Waypoint SDK and registers the interfaces for the go-plugin system for you. All you need to do is pass Main the components your Plugin implements using the sdk.WithComponents function. Since this is the default template, all the different plugin components are registered.

func main() {
    // sdk.Main allows you to register the components which should
    // be included in your plugin
    // Main sets up all the go-plugin requirements

    sdk.Main(sdk.WithComponents(
        // Comment out any components which are not
        // required for your plugin
        &builder.Builder{},
        &registry.Registry{},
        &platform.Platform{},
        &release.ReleaseManager{},
    ))
}

The plugin you will build in this guide only implements the Builder component so you can remove the other components. Your final Main block should look like the following:

    sdk.Main(sdk.WithComponents(
        &builder.Builder{},
    ))
