Functions

func SafeSysctlWhitelist

func SafeSysctlWhitelist() []string

SafeSysctlWhitelist returns the whitelist of safe sysctls and safe sysctl patterns (ending in *).

A sysctl is called safe iff - it is namespaced in the container or the pod - it is isolated, i.e. has no influence on any other pod on the same node.

Types

type SysctlsStrategy

type SysctlsStrategy interface {
	// Validate ensures that the specified values fall within the range of the strategy.
	Validate(pod *api.Pod) field.ErrorList
}

SysctlsStrategy defines the interface for all sysctl strategies.

func NewMustMatchPatterns

func NewMustMatchPatterns(safeWhitelist, allowedUnsafeSysctls, forbiddenSysctls []string) SysctlsStrategy

NewMustMatchPatterns creates a new mustMatchPatterns strategy that will provide validation. Passing nil means the default pattern, passing an empty list means to disallow all sysctls.
