Functions ¶
func RegisterService ¶
func RegisterService(r Registration) error
RegisterService is a function that registers a service with the service registry.
Types ¶
type DBRegister ¶ added in v0.3.0
type DBRegister struct {
// Required is a flag that indicates whether the service requires a database connection.
Required bool
// Migrations is an embedded filesystem that contains the Goose SQL migrations for the service.
// This is required to support the `migrate` command or the `runMigrations` configuration option.
// More information on Goose can be found at https://github.com/pressly/goose
Migrations *embed.FS
}
DBRegister is a struct that holds the information needed to register a service with a database
type HandlerServer ¶
type NamespaceMap ¶ added in v0.3.0
type NamespaceMap map[string]ServiceMap
var RegisteredServices NamespaceMap
RegisteredServices is a map of namespaces to services TODO remove the global variable and move towards a more functional approach
type RegisterFunc ¶
type RegisterFunc func(RegistrationParams) (Impl any, HandlerServer HandlerServer)
type Registration ¶
type Registration struct {
// Namespace is the namespace of the service. One or more gRPC services can be registered under
// the same namespace.
Namespace string
// ServiceDesc is the gRPC service descriptor. For non-gRPC services, this can be mocked out,
// but at minimum, the ServiceName field must be set
ServiceDesc *grpc.ServiceDesc
// RegisterFunc is the function that will be called to register the service
RegisterFunc RegisterFunc
// DB is optional and used to register the service with a database
DB DBRegister
}
Registration is a struct that holds the information needed to register a service
type RegistrationParams ¶
type RegistrationParams struct {
// Config scoped to the service config. Since the main config contains all the service configs,
// which could have need-to-know information we don't want to expose it to all services.
Config ServiceConfig
// OTDF is the OpenTDF server that can be used to interact with the OpenTDFServer instance.
OTDF *server.OpenTDFServer
// DBClient is the database client that can be used to interact with the database. This client
// is scoped to the service namespace and will not be shared with other service namespaces.
DBClient *db.Client
// SDK is the OpenTDF SDK that can be used to interact with the OpenTDF SDK. This is useful for
// gRPC Inter Process Communication (IPC) between services. This ensures the services are
// communicating with each other by contract as well as supporting the various deployment models
// that OpenTDF supports.
SDK *sdk.SDK
// Logger is the logger that can be used to log messages. This logger is scoped to the service
Logger *logger.Logger
// RegisterWellKnownConfig is a function that can be used to register a well-known configuration
WellKnownConfig func(namespace string, config any) error
// RegisterReadinessCheck is a function that can be used to register a readiness check for the
// service. This is useful for services that need to perform some initialization before they are
// ready to serve requests. This function should be called in the RegisterFunc function.
RegisterReadinessCheck func(namespace string, check func(context.Context) error) error
}
RegistrationParams is a struct that holds the parameters needed to register a service with the service registry. These parameters are passed to the RegisterFunc function defined in the Registration struct.
type RemoteServiceConfig ¶
type RemoteServiceConfig struct {
Endpoint string `yaml:"endpoint"`
}
type Service ¶
type Service struct {
Registration
// Started is a flag that indicates whether the service has been started
Started bool
// Close is a function that can be called to close the service
Close func()
}
Service is a struct that holds the registration information for a service as well as the state of the service within the instance of the platform.
type ServiceConfig ¶
type ServiceConfig struct {
Enabled bool `yaml:"enabled"`
Remote RemoteServiceConfig `yaml:"remote"`
ExtraProps map[string]interface{} `json:"-" mapstructure:",remain"`
}
ServiceConfig is a struct that holds the configuration for a service and used for the global config rollup powered by Viper (https://github.com/spf13/viper)
