var KubeletReservedPorts = map[string]bool{
	StreamServerPort: true,
	KubeletPort:      true,
}

These ports can always be accessed via the tunnel server, at the loopback address. Other addresses and ports are only accessible via the tunnel on newer agents, when used by a pod.

Functions

func GetArgs 

func GetArgs(initialArgs map[string]string, extraArgs []string) []string

GetArgs appends extra arguments to existing arguments with logic to override any default arguments whilst also allowing to prefix and suffix default string slice arguments.

func (*Control) BindAddressOrLoopback 

func (c *Control) BindAddressOrLoopback(chooseHostInterface, urlSafe bool) string

BindAddressOrLoopback returns an IPv4 or IPv6 address suitable for embedding in server URLs. If a bind address was configured, that is returned. If the chooseHostInterface parameter is true, and a suitable default interface can be found, that interface's address is returned. If neither of the previous were used, the loopback address is returned. If the urlSafe parameter is true, IPv6 addresses are enclosed in square brackets, as per RFC2732.

func (*Control) Loopback 

func (c *Control) Loopback(urlSafe bool) string

Loopback returns an IPv4 or IPv6 loopback address, depending on whether the cluster service CIDRs indicate an IPv4/Dual-Stack or IPv6 only cluster. If the urlSafe parameter is true, IPv6 addresses are enclosed in square brackets, as per RFC2732.
