Constants

const (
    PromHandlerV0Data     = "v0/data"
    PromHandlerV1Data     = "v1/data"
    PromHandlerV1Query    = "v1/query"
    PromHandlerV1Policies = "v1/policies"
    PromHandlerV1Compile  = "v1/compile"
    PromHandlerIndex      = "index"
    PromHandlerCatch      = "catchall"
    PromHandlerHealth     = "health"
)

Set of handlers for use in the "handler" dimension of the duration metric.

type AuthenticationScheme Uses

type AuthenticationScheme int

AuthenticationScheme enumerates the supported authentication schemes. The authentication scheme determines how client identities are established.

const (
    AuthenticationOff AuthenticationScheme = iota
    AuthenticationToken
    AuthenticationTLS
)

Set of supported authentication schemes.

type AuthorizationScheme Uses

type AuthorizationScheme int

AuthorizationScheme enumerates the supported authorization schemes. The authorization scheme determines how access to OPA is controlled.

const (
    AuthorizationOff AuthorizationScheme = iota
    AuthorizationBasic
)

Set of supported authorization schemes.

type Buffer Uses

type Buffer interface {
    // Push adds the given Info into the buffer.
    Push(*Info)

    // Iter iterates over the buffer, from oldest present Info to newest. It should
    // call fn on each Info.
    Iter(fn func(*Info))
}

Buffer defines an interface for recording decisions. DEPRECATED. Use Decision Logging instead.

type BundleInfo Uses

type BundleInfo struct {
    Revision string
}

BundleInfo contains information describing a bundle

type Info Uses

type Info struct {
    Txn        storage.Transaction
    Revision   string // Deprecated: Use `Bundles` instead
    Bundles    map[string]BundleInfo
    DecisionID string
    RemoteAddr string
    Query      string
    Path       string
    Timestamp  time.Time
    Input      *interface{}
    Results    *interface{}
    Error      error
    Metrics    metrics.Metrics
    Trace      []*topdown.Event
}

Info contains information describing a policy decision.

type Loop Uses

type Loop func() error

Loop will contain all the calls from the server that we'll be listening on.

type Metrics Uses

type Metrics interface {
    RegisterEndpoints(registrar func(path, method string, handler http.Handler))
    InstrumentHandler(handler http.Handler, label string) http.Handler
}

Metrics defines the interface that the server requires for recording HTTP handler metrics.

type Server Uses

type Server struct {
    Handler           http.Handler
    DiagnosticHandler http.Handler
    // contains filtered or unexported fields
}

Server represents an instance of OPA running in server mode.

func New Uses

func New() *Server

New returns a new Server.

func (*Server) Addrs Uses

func (s *Server) Addrs() []string

Addrs returns a list of addresses that the server is listening on. If the server hasn't been started it will not return an address.

func (*Server) DiagnosticAddrs Uses

func (s *Server) DiagnosticAddrs() []string

DiagnosticAddrs returns a list of addresses that the server is listening on for the read-only diagnostic API's (eg /health, /metrics, etc) If the server hasn't been started it will not return an address.

func (*Server) Init Uses

func (s *Server) Init(ctx context.Context) (*Server, error)

Init initializes the server. This function MUST be called before Loop.

func (*Server) Listeners Uses

func (s *Server) Listeners() ([]Loop, error)

Listeners returns functions that listen and serve connections.

func (*Server) Shutdown Uses

func (s *Server) Shutdown(ctx context.Context) error

Shutdown will attempt to gracefully shutdown each of the http servers currently in use by the OPA Server. If any exceed the deadline specified by the context an error will be returned.

func (*Server) WithAddresses Uses

func (s *Server) WithAddresses(addrs []string) *Server

WithAddresses sets the listening addresses that the server will bind to.

func (*Server) WithAuthentication Uses

func (s *Server) WithAuthentication(scheme AuthenticationScheme) *Server

func (*Server) WithAuthorization Uses

func (s *Server) WithAuthorization(scheme AuthorizationScheme) *Server

WithAuthorization sets authorization scheme to use on the server.

func (*Server) WithCertPool Uses

func (s *Server) WithCertPool(pool *x509.CertPool) *Server

func (*Server) WithDecisionIDFactory Uses

func (s *Server) WithDecisionIDFactory(f func() string) *Server

WithDecisionIDFactory sets a function on the server to generate decision IDs.

func (*Server) WithDecisionLogger Uses

func (s *Server) WithDecisionLogger(logger func(context.Context, *Info)) *Server

WithDecisionLogger sets the decision logger used by the server. DEPRECATED. Use WithDecisionLoggerWithErr instead.
