Functions

func AddNoNewPrivileges

func AddNoNewPrivileges(sc *v1.SecurityContext) bool

AddNoNewPrivileges returns if we should add the no_new_privs option.

func DetermineEffectiveSecurityContext

func DetermineEffectiveSecurityContext(pod *v1.Pod, container *v1.Container) *v1.SecurityContext

func HasCapabilitiesRequest

func HasCapabilitiesRequest(container *v1.Container) bool

HasCapabilitiesRequest returns true if Adds or Drops are defined in the security context capabilities, taking into account nils

func HasPrivilegedRequest

func HasPrivilegedRequest(container *v1.Container) bool

HasPrivilegedRequest returns the value of SecurityContext.Privileged, taking into account the possibility of nils

func ParseSELinuxOptions

func ParseSELinuxOptions(context string) (*v1.SELinuxOptions, error)

ParseSELinuxOptions parses a string containing a full SELinux context (user, role, type, and level) into an SELinuxOptions object. If the context is malformed, an error is returned.

func ValidInternalSecurityContextWithContainerDefaults

func ValidInternalSecurityContextWithContainerDefaults() *api.SecurityContext

ValidInternalSecurityContextWithContainerDefaults creates a valid security context provider based on empty container defaults. Used for testing.

func ValidSecurityContextWithContainerDefaults

func ValidSecurityContextWithContainerDefaults() *v1.SecurityContext

ValidSecurityContextWithContainerDefaults creates a valid security context provider based on empty container defaults. Used for testing.

Types

type ContainerSecurityContextAccessor

type ContainerSecurityContextAccessor interface {
	Capabilities() *api.Capabilities
	Privileged() *bool
	SELinuxOptions() *api.SELinuxOptions
	RunAsUser() *int64
	RunAsNonRoot() *bool
	ReadOnlyRootFilesystem() *bool
	AllowPrivilegeEscalation() *bool
}

func NewContainerSecurityContextAccessor

func NewContainerSecurityContextAccessor(containerSC *api.SecurityContext) ContainerSecurityContextAccessor

func NewEffectiveContainerSecurityContextAccessor

func NewEffectiveContainerSecurityContextAccessor(podSC PodSecurityContextAccessor, containerSC ContainerSecurityContextMutator) ContainerSecurityContextAccessor

type ContainerSecurityContextMutator

type ContainerSecurityContextMutator interface {
	ContainerSecurityContextAccessor

	ContainerSecurityContext() *api.SecurityContext

	SetCapabilities(*api.Capabilities)
	SetPrivileged(*bool)

func NewContainerSecurityContextMutator

func NewContainerSecurityContextMutator(containerSC *api.SecurityContext) ContainerSecurityContextMutator

func NewEffectiveContainerSecurityContextMutator

func NewEffectiveContainerSecurityContextMutator(podSC PodSecurityContextAccessor, containerSC ContainerSecurityContextMutator) ContainerSecurityContextMutator

type PodSecurityContextAccessor

type PodSecurityContextAccessor interface {
	HostNetwork() bool

}

PodSecurityContextAccessor allows reading the values of a PodSecurityContext object

func NewPodSecurityContextAccessor

func NewPodSecurityContextAccessor(podSC *api.PodSecurityContext) PodSecurityContextAccessor

NewPodSecurityContextAccessor returns an accessor for the given pod security context. May be initialized with a nil PodSecurityContext.

type PodSecurityContextMutator

type PodSecurityContextMutator interface {
	PodSecurityContextAccessor

	SetHostNetwork(bool)
	SetHostPID(bool)
	SetHostIPC(bool)
	SetSELinuxOptions(*api.SELinuxOptions)
	SetRunAsUser(*int64)
	SetRunAsNonRoot(*bool)
	SetSupplementalGroups([]int64)
	SetFSGroup(*int64)

	// PodSecurityContext returns the current PodSecurityContext object
	PodSecurityContext() *api.PodSecurityContext
}

PodSecurityContextMutator allows reading and writing the values of a PodSecurityContext object

func NewPodSecurityContextMutator

func NewPodSecurityContextMutator(podSC *api.PodSecurityContext) PodSecurityContextMutator

NewPodSecurityContextMutator returns a mutator for the given pod security context. May be initialized with a nil PodSecurityContext.
