Types ¶
type ClusterCache ¶
ClusterCache manages the contents of the gRPC CDS cache.
func (*ClusterCache) Contents ¶
func (c *ClusterCache) Contents() []proto.Message
Contents returns a copy of the cache's contents.
func (*ClusterCache) OnChange ¶
func (c *ClusterCache) OnChange(root *dag.DAG)
func (*ClusterCache) TypeURL ¶
func (*ClusterCache) TypeURL() string
func (*ClusterCache) Update ¶
func (c *ClusterCache) Update(v map[string]*envoy_cluster_v3.Cluster)
Update replaces the contents of the cache with the supplied map.
type EndpointsCache ¶
type EndpointsCache struct {
// contains filtered or unexported fields
}
EndpointsCache is a cache of Endpoint and ServiceCluster objects.
func (*EndpointsCache) DeleteEndpoint ¶
func (c *EndpointsCache) DeleteEndpoint(ep *v1.Endpoints)
DeleteEndpoint deletes ep from the cache. Any ServiceClusters that are backed by a Service that ep belongs become stale.
func (*EndpointsCache) Recalculate ¶
func (c *EndpointsCache) Recalculate() map[string]*envoy_endpoint_v3.ClusterLoadAssignment
Recalculate regenerates all the ClusterLoadAssignments from the cached Endpoints and stale ServiceClusters. A ClusterLoadAssignment will be generated for every stale ServerCluster, however, if there are no endpoints for the Services in the ServiceCluster, the ClusterLoadAssignment will be empty.
func (*EndpointsCache) SetClusters ¶
func (c *EndpointsCache) SetClusters(clusters []*dag.ServiceCluster) error
SetClusters replaces the cache of ServiceCluster resources. All the added clusters will be marked stale.
func (*EndpointsCache) UpdateEndpoint ¶
func (c *EndpointsCache) UpdateEndpoint(ep *v1.Endpoints)
UpdateEndpoint adds ep to the cache, or replaces it if it is already cached. Any ServiceClusters that are backed by a Service that ep belongs become stale.
type EndpointsTranslator ¶
type EndpointsTranslator struct { // Observer notifies when the endpoints cache has been updated. Observer contour.Observer contour.Cond logrus.FieldLogger // contains filtered or unexported fields }
A EndpointsTranslator translates Kubernetes Endpoints objects into Envoy ClusterLoadAssignment resources.
func NewEndpointsTranslator ¶
func NewEndpointsTranslator(log logrus.FieldLogger) *EndpointsTranslator
NewEndpointsTranslator allocates a new endpoints translator.
func (*EndpointsTranslator) Contents ¶
func (e *EndpointsTranslator) Contents() []proto.Message
Contents returns a copy of the contents of the cache.
func (*EndpointsTranslator) Merge ¶
func (e *EndpointsTranslator) Merge(entries map[string]*envoy_endpoint_v3.ClusterLoadAssignment)
Merge combines the given entries with the existing entries in the EndpointsTranslator. If the same key exists in both maps, an existing entry is replaced.
func (*EndpointsTranslator) OnAdd ¶
func (e *EndpointsTranslator) OnAdd(obj interface{})
func (*EndpointsTranslator) OnChange ¶
func (e *EndpointsTranslator) OnChange(d *dag.DAG)

Contents returns a copy of the cache's contents.
func (*ListenerCache) OnChange ¶
func (c *ListenerCache) OnChange(root *dag.DAG)
func (*ListenerCache) Query ¶
func (c *ListenerCache) Query(names []string) []proto.Message
Query returns the proto.Messages in the ListenerCache that match a slice of strings
func (*ListenerCache) TypeURL ¶
func (*ListenerCache) TypeURL() string
func (*ListenerCache) Update ¶
func (c *ListenerCache) Update(v map[string]*envoy_listener_v3.Listener)
Update replaces the contents of the cache with the supplied map.
type ListenerConfig ¶
type ListenerConfig struct { // Envoy's HTTP (non TLS) listener address. // If not set, defaults to DEFAULT_HTTP_LISTENER_ADDRESS. HTTPAddress string // Envoy's HTTP (non TLS) listener port. // If not set, defaults to DEFAULT_HTTP_LISTENER_PORT. HTTPPort int // Envoy's HTTP (non TLS) access log path. // If not set, defaults to DEFAULT_HTTP_ACCESS_LOG.

HTTPSAddress string // Envoy's HTTPS (TLS) listener port. // If not set, defaults to DEFAULT_HTTPS_LISTENER_PORT. HTTPSPort int // Envoy's HTTPS (TLS) access log path. // If not set, defaults to DEFAULT_HTTPS_ACCESS_LOG. HTTPSAccessLog string // UseProxyProto configures all listeners to expect a PROXY // V1 or V2 preamble. // If not set, defaults to false. UseProxyProto bool // MinimumTLSVersion defines the minimum TLS protocol version the proxy should accept. MinimumTLSVersion string // CipherSuites defines the ciphers Envoy TLS listeners will accept when // negotiating TLS 1.2. CipherSuites []string // DefaultHTTPVersions defines the default set of HTTP // versions the proxy should accept. If not specified, all // supported versions are accepted.
