Functions

func SysctlsFromPodAnnotations 

func SysctlsFromPodAnnotations(a map[string]string) ([]Sysctl, []Sysctl, error)

SysctlsFromPodAnnotations parses the sysctl annotations into a slice of safe Sysctls and a slice of unsafe Sysctls. This is only a convenience wrapper around SysctlsFromPodAnnotation.

Types

type APIConfig
