Types

type AuthenticationScheme

type AuthenticationScheme int

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

const (
	AuthenticationOff   AuthenticationScheme = iota
	AuthenticationToken                      = iota
)

Set of supported authentication schemes.

type AuthorizationScheme

type AuthorizationScheme int

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

const (
	AuthorizationOff   AuthorizationScheme = iota
	AuthorizationBasic                     = iota
)

Set of supported authorization schemes.

type Server

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

Server represents an instance of OPA running in server mode.

func New

func New() *Server

New returns a new Server.

func (*Server) Compiler

func (s *Server) Compiler() *ast.Compiler

Compiler returns the server's compiler.

The server's compiler contains the compiled versions of all modules added to the server as well as data structures for performing query analysis. This is intended to allow services to embed the OPA server while still relying on the topdown package for query evaluation.

func (*Server) Init

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

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

func (*Server) Listeners

func (s *Server) Listeners() (func() error, func() error)

Listeners returns functions that listen and serve connections.

func (*Server) WithAddress

func (s *Server) WithAddress(addr string) *Server

WithAddress sets the listening address that the server will bind to.

func (*Server) WithAuthentication

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

WithAuthentication sets authentication scheme to use on the server.

func (*Server) WithAuthorization

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

WithAuthorization sets authorization scheme to use on the server.

func (*Server) WithCertificate

func (s *Server) WithCertificate(cert *tls.Certificate) *Server

WithCertificate sets the server-side certificate that the server will use.

func (*Server) WithCompilerErrorLimit

func (s *Server) WithCompilerErrorLimit(limit int) *Server

WithCompilerErrorLimit sets the limit on the number of compiler errors the server will allow.

func (*Server) WithInsecureAddress

func (s *Server) WithInsecureAddress(addr string) *Server

WithInsecureAddress sets the listening address that the server will bind to.

func (*Server) WithStore

func (s *Server) WithStore(store storage.Store) *Server

WithStore sets the storage used by the server.
