Types

type Option

type Option func(*options)

Option is option to configure dnsresovle chain elements

func WithNSMgrProxyService

func WithNSMgrProxyService(service string) Option

WithNSMgrProxyService sets default service of nsmgr-proxy to lookup DNS SRV records

func WithRegistryService

func WithRegistryService(service string) Option

WithRegistryService sets default service of nsmgr-proxy to lookup DNS SRV records

func WithResolver

func WithResolver(r Resolver) Option

type Resolver

type Resolver interface {
	// LookupSRV tries to resolve an SRV query of the given service,
	// protocol, and domain name. The proto is "tcp" or "udp".
	// The returned records are sorted by priority and randomized
	// by weight within a priority.
	LookupSRV(ctx context.Context, service, proto, name string) (string, []*net.SRV, error)
	// LookupIPAddr looks up host using the local resolver.
	// It returns a slice of that host's IPv4 and IPv6 addresses.
	LookupIPAddr(ctx context.Context, host string) ([]net.IPAddr, error)
}

Resolver is DNS resolver
