type Conntracker

type Conntracker interface {
	// SetMax adjusts nf_conntrack_max.
	SetMax(max int) error
	// SetTCPEstablishedTimeout adjusts nf_conntrack_tcp_timeout_established.
	SetTCPEstablishedTimeout(seconds int) error
	// SetTCPCloseWaitTimeout nf_conntrack_tcp_timeout_close_wait.

type Options

type Options struct {
	// ConfigFile is the location of the proxy server's configuration file.
	ConfigFile string
	// WriteConfigTo is the path where the default configuration will be written.
	WriteConfigTo string
	// CleanupAndExit, when true, makes the proxy server clean up iptables rules, then exit.
	CleanupAndExit bool
	// CleanupIPVS, when true, makes the proxy server clean up ipvs rules before running.
	CleanupIPVS bool
	// WindowsService should be set to true if kube-proxy is running as a service on Windows.
	// Its corresponding flag only gets registered in Windows builds
	WindowsService bool
	// contains filtered or unexported fields

Options contains everything necessary to create and run a proxy server.

func NewProxyServer

func NewProxyServer(o *Options) (*ProxyServer, error)
