Functions

func NewLoggingHandler

func NewLoggingHandler(inner http.Handler) http.Handler

NewLoggingHandler returns a new http.Handler.

Types

type LoggingConfig added in v0.4.6

type LoggingConfig struct {
	Level  string
	Format string
}

LoggingConfig stores the configuration for OPA's logging behaviour.

type LoggingHandler

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

LoggingHandler returns an http.Handler that will print log messages 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

	// InsecureAddr is the listening address that the OPA server will bind to
	// in addition to Addr if TLS is enabled.
	InsecureAddr string

	// Authentication is the type of authentication scheme to use.
	Authentication server.AuthenticationScheme

	// Authorization is the type of authorization scheme to use.
	Authorization server.AuthorizationScheme

	// Certificate is the certificate to use in server-mode. If the certificate
	// is nil, the server will NOT use TLS.
	Certificate *tls.Certificate

	// Eval is a string to evaluate in the REPL.
	Eval 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. Data files may be prefixed with "<dotted-path>:" to indicate
	// where the contained document should be loaded.
	Paths []string

	// Watch flag controls whether OPA will watch the Paths files for changes.
	// If this flag is true, OPA will watch the Paths files for changes and
	// reload the storage layer each time they change. This is useful for
	// interactive development.
	Watch bool

	// ErrorLimit is the number of errors the compiler will allow to occur before
	// exiting early.
	ErrorLimit int

	// DecisionIDFactory generates decision IDs to include in API responses
	// sent by the server (in response to Data API queries.)
	DecisionIDFactory func() string

	// DiagnosticsBuffer is used by the server to record policy decisions.
	DiagnosticsBuffer server.Buffer

	// Logging configures the logging behaviour.
	Logging LoggingConfig

	// Output is the output stream used when run as an interactive shell. This
	// is mostly for test purposes.
	Output io.Writer
}

Params stores the configuration for an OPA instance.

func NewParams added in v0.2.2

func NewParams() Params

NewParams returns a new Params object.

type Runtime

type Runtime struct {
	Params Params
	Store  storage.Store
}

Runtime represents a single OPA instance.

func NewRuntime added in v0.5.9

func NewRuntime(ctx context.Context, params Params) (*Runtime, error)

NewRuntime returns a new Runtime object initialized with params.

func (*Runtime) StartREPL added in v0.5.9

func (rt *Runtime) StartREPL(ctx context.Context)

StartREPL starts the runtime in REPL mode. This function will block the calling goroutine.

func (*Runtime) StartServer added in v0.5.9

func (rt *Runtime) StartServer(ctx context.Context)

StartServer starts the runtime in server mode. This function will block the calling goroutine.
