Functions

func GetProfileName

func GetProfileName(pod *v1.Pod, containerName string) string

GetProfileName returns the name of the profile to use with the container.

func GetProfileNameFromPodAnnotations

func GetProfileNameFromPodAnnotations(annotations map[string]string, containerName string) string

GetProfileNameFromPodAnnotations gets the name of the profile to use with container from pod annotations

func IsAppArmorEnabled

func IsAppArmorEnabled() bool

IsAppArmorEnabled returns true if apparmor is enabled for the host. This function is forked from https://github.com/opencontainers/runc/blob/1a81e9ab1f138c091fe5c86d0883f87716088527/libcontainer/apparmor/apparmor.go to avoid the libapparmor dependency.

func SetProfileName

func SetProfileName(pod *v1.Pod, containerName, profileName string) error

SetProfileName sets the name of the profile to use with the container.

func SetProfileNameFromPodAnnotations

func SetProfileNameFromPodAnnotations(annotations map[string]string, containerName, profileName string) error

SetProfileNameFromPodAnnotations sets the name of the profile to use with the container.

func ValidateProfileFormat

func ValidateProfileFormat(profile string) error

ValidateProfileFormat checks the format of the profile.

Types

type Validator

type Validator interface {
	Validate(pod *v1.Pod) error
	ValidateHost() error
}
