Overview ¶
Package filters contains all the http handler chain filters which _are_ api related, i.e. which are prerequisite for the API services to work (in contrast to the filters in the server package which are not part of the API contract).

Functions ¶
func GetAuthorizerAttributes ¶
func GetAuthorizerAttributes(ctx context.Context) (authorizer.Attributes, error)
func Unauthorized ¶
func Unauthorized(s runtime.NegotiatedSerializer) http.Handler
func WithAudit ¶
func WithAudit(handler http.Handler, sink audit.Sink, policy policy.Checker, longRunningCheck request.LongRunningRequestCheck) http.Handler
WithAudit decorates a http.Handler with audit logging information for all the requests coming to the server. Audit level is decided according to requests' attributes and audit policy. Logs are emitted to the audit sink to process events. If sink or audit policy is nil, no decoration takes place.
func WithAuditAnnotations ¶ added in v0.19.0
func WithAuditAnnotations(handler http.Handler, sink audit.Sink, policy policy.Checker) http.Handler
WithAuditAnnotations decorates a http.Handler with a []{key, value} that is merged with the audit.Event.Annotations map. This allows layers that run before WithAudit (such as authentication) to assert annotations. If sink or audit policy is nil, no decoration takes place.
func WithAuthentication ¶
func WithAuthentication(handler http.Handler, auth authenticator.Request, failed http.Handler, apiAuds authenticator.Audiences) http.Handler
WithAuthentication creates an http handler that tries to authenticate the given request as a user, and then stores any such user found onto the provided context for the request. If authentication fails or returns an error the failed handler is used. On success, "Authorization" header is removed from the request and handler is invoked to serve the request.
func WithAuthorization ¶
func WithAuthorization(handler http.Handler, a authorizer.Authorizer, s runtime.NegotiatedSerializer) http.Handler
WithAuthorizationCheck passes all authorized requests on to handler, and returns a forbidden error otherwise.
func WithCacheControl ¶ added in v0.16.4
WithCacheControl sets the Cache-Control header to "no-cache, private" because all servers are protected by authn/authz. see https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/http-caching#defining_optimal_cache-control_policy
func WithFailedAuthenticationAudit ¶
func WithFailedAuthenticationAudit(failedHandler http.Handler, sink audit.Sink, policy policy.Checker) http.Handler
WithFailedAuthenticationAudit decorates a failed http.Handler used in WithAuthentication handler. It is meant to log only failed authentication requests.
func WithImpersonation ¶
func WithImpersonation(handler http.Handler, a authorizer.Authorizer, s runtime.NegotiatedSerializer) http.Handler
WithImpersonation is a filter that will inspect and check requests that attempt to change the user.Info for their requests
func WithRequestInfo ¶
WithRequestInfo attaches a RequestInfo to the context.
func WithRequestReceivedTimestamp ¶ added in v0.20.0
WithRequestReceivedTimestamp attaches the ReceivedTimestamp (the time the request reached the apiserver) to the context.
func WithStorageVersionPrecondition ¶ added in v0.20.0
func WithStorageVersionPrecondition(handler http.Handler, svm storageversion.Manager, s runtime.NegotiatedSerializer) http.Handler
WithStorageVersionPrecondition checks if the storage version barrier has completed, if not, it only passes the following API requests: 1. non-resource requests, 2. read requests, 3. write requests to the storageversion API, 4. create requests to the namespace API sent by apiserver itself, 5. write requests to the lease API in kube-system namespace, 6. resources whose StorageVersion is not pending update, including non-persisted resources.
