Functions

func NewLoggingHandler

func NewLoggingHandler(inner http.Handler) http.Handler

NewLoggingHandler returns a new http.Handler.

Types

type LoggingHandler

type LoggingHandler struct {
	// contains filtered or unexported fields
}

LoggingHandler returns an http.Handler that will print log messages to glog containing the request information as well as response status and latency.

func (*LoggingHandler) ServeHTTP

func (h *LoggingHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)

type Params

type Params struct {

	// Addr is the listening address that the OPA server will bind to.
	Addr string

	// HistoryPath is the filename to store the interactive shell user
	// input history.
	HistoryPath string

	// Output format controls how the REPL will print query results.
	// Default: "pretty".
	OutputFormat string

	// Paths contains filenames of base documents and policy modules to
	// load on startup.
	Paths []string

	// PolicyDir is the filename of the directory to persist policy
	// definitions in. Policy definitions stored in this directory
	// are automatically loaded on startup.
	PolicyDir string

	// Server flag controls whether the OPA instance will start a server.
	// By default, the OPA instance acts as an interactive shell.
	Server bool
}

Params stores the configuration for an OPA instance.

type Runtime

type Runtime struct {
	DataStore   *storage.DataStore
	PolicyStore *storage.PolicyStore
}

Runtime represents a single OPA instance.

func (*Runtime) Init

func (rt *Runtime) Init(params *Params) error

Init initializes the OPA instance.

func (*Runtime) Start

func (rt *Runtime) Start(params *Params)

Start is the entry point of an OPA instance.

type Server

type Server struct {
	Addr    string
	Persist bool
	Runtime *Runtime
	Router  *mux.Router
	// contains filtered or unexported fields
}

Server contains runtime state specific to the server-mode persona, e.g., HTTP router.

Notes:

- In the future, the HTTP routing could be factored into a separate module relying on the server (which would remain RPC-based). For now, it's simpler to keep the HTTP routing and backend implementation in one place.

func NewServer

func NewServer(rt *Runtime, addr string, persist bool) *Server

NewServer returns a new Server.

func (*Server) Loop

func (s *Server) Loop() error

Loop starts the server. This function does not return.
