Types ¶
type Service ¶
type Service struct {
// If set, use the given static network configuration instead of relying on
// autoconfiguration.
StaticConfig *netpb.Net
// List of IPs which get configured onto the loopback interface and the
// integrated DNS server is serving on. Cannot be changed at runtime.
// This is a hack to work around CoreDNS not being able to change listeners
// on-the-fly without breaking everything. This will go away once its
// frontend got replaced by something which can do that.
ExtraDNSListenerIPs []net.IP
// Vendor Class identifier of the system
DHCPVendorClassID string
// Status is the current status of the network as seen by the service.
Status memory.Value[*Status]
// contains filtered or unexported fields
}
Service is the network service for this node. It maintains all networking-related functionality, but is generally not aware of the inner workings of Metropolis, instead functioning in a generic manner. Once created via New, it can be started and restarted arbitrarily, but the service object itself must be long-lived.
func New ¶
New instantiates a new network service. If autoconfiguration is desired, staticConfig must be set to nil. If staticConfig is set to a non-nil value, it will be used instead of autoconfiguration.
func (*Service) ConfigureDNS ¶
func (s *Service) ConfigureDNS(d *dns.ExtraDirective)
ConfigureDNS sets a DNS ExtraDirective on the built-in DNS server of the network Service. See //metropolis/node/core/network/dns for more information.
type Status ¶
type Status struct {
ExternalAddress net.IP
DNSServers dhcp4c.DNSServers
}
Status is the current network status of the host. It will be updated by the network Service whenever the node's network configuration changes. Spurious changes might occur, consumers should ensure that the change that occured is meaningful to them.
