Functions ¶

func NewProxyCommand ¶

func NewProxyCommand() *cobra.Command

NewProxyCommand creates a *cobra.Command object with default parameters

Types ¶

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.
	SetTCPCloseWaitTimeout(seconds int) error
}

Conntracker is an interface to the global sysctl. Descriptions of the various sysctl fields can be found here:

https://www.kernel.org/doc/Documentation/networking/nf_conntrack-sysctl.txt

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 and ipvs rules, then exit.
	CleanupAndExit 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 NewOptions ¶

func NewOptions() *Options

NewOptions returns initialized Options

func (*Options) AddFlags ¶

func (o *Options) AddFlags(fs *pflag.FlagSet)

AddFlags adds flags to fs and binds them to options.

func (*Options) Complete ¶

func (o *Options) Complete() error

Complete completes all the required options.

func (*Options) Run ¶

func (o *Options) Run() error

Run runs the specified ProxyServer.

func (*Options) Validate ¶

func (o *Options) Validate() error

Validate validates all the required options.

type ProxyServer ¶

type ProxyServer struct {
	Config *kubeproxyconfig.KubeProxyConfiguration

	Client          clientset.Interface
	Broadcaster     events.EventBroadcaster
	Recorder        events.EventRecorder
	NodeRef         *v1.ObjectReference
	HealthzServer   healthcheck.ProxierHealthUpdater
	Hostname        string
	PrimaryIPFamily v1.IPFamily
	NodeIPs         map[v1.IPFamily]net.IP

	Proxier proxy.Provider
	// contains filtered or unexported fields
}

ProxyServer represents all the parameters required to start the Kubernetes proxy server. All fields are required.

func (*ProxyServer) Run ¶

func (s *ProxyServer) Run() error

Run runs the specified ProxyServer. This should never exit (unless CleanupAndExit is set). TODO: At the moment, Run() cannot return a nil error, otherwise it's caller will never exit. Update callers of Run to handle nil errors.
