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 

type APIConfig struct {
	// Listen is the path to the AF_LOCAL socket on which cri-o will listen.
	// This may support proto://addr formats later, but currently this is just
	// a path.
	Listen string `toml:"listen"`

	// StreamAddress is the IP address on which the stream server will listen.
	StreamAddress string `toml:"stream_address"`
