Functions

func FailOnResolutionFailure

func FailOnResolutionFailure(imageResolutionType ImageResolutionType) bool

FailOnResolutionFailure returns true if you should fail when resolution fails

func RegisterDeepCopies

func RegisterDeepCopies(scheme *runtime.Scheme) error

RegisterDeepCopies adds deep-copy functions to the given scheme. Public to allow building arbitrary schemes.

Deprecated: deepcopy registration will go away when static deepcopy is fully implemented.

func RequestsResolution

func RequestsResolution(imageResolutionType ImageResolutionType) bool

RequestsResolution returns true if you should attempt to resolve image pull specs

func RewriteImagePullSpec

func RewriteImagePullSpec(imageResolutionType ImageResolutionType) bool

RewriteImagePullSpec returns true if you should rewrite image pull specs when resolution succeeds

Types

type ImageCondition

type ImageCondition struct {
	// Name is the name of this policy rule for reference. It must be unique across all rules.
	Name string
	// IgnoreNamespaceOverride prevents this condition from being overridden when the
	// `alpha.image.policy.openshift.io/ignore-rules` is set on a namespace and contains this rule name.
	IgnoreNamespaceOverride bool

	// OnResources determines which resources this applies to. Defaults to 'pods' for ImageExecutionPolicyRules.
	OnResources []schema.GroupResource

	// InvertMatch means the value of the condition is logically inverted (true -> false, false -> true).
	InvertMatch bool

	// MatchIntegratedRegistry will only match image sources that originate from the configured integrated
	// registry.
	MatchIntegratedRegistry bool
	// MatchRegistries will match image references that point to the provided registries. If any of the listed
	// registries match, this condition is satisfied.
	MatchRegistries []string

	// SkipOnResolutionFailure allows the subsequent conditions to be bypassed if the integrated registry does
	// not have access to image metadata (no image exists matching the image digest).
	SkipOnResolutionFailure bool

	// MatchDockerImageLabels checks against the resolved image for the presence of a Docker label. All conditions
	// must match.
	MatchDockerImageLabels []ValueCondition
	// MatchImageLabels checks against the resolved image for a label. All conditions must match.
	MatchImageLabels []metav1.LabelSelector
	// MatchImageLabelSelectors is the processed form of MatchImageLabels. All conditions must match.
	MatchImageLabelSelectors []labels.Selector
	// MatchImageAnnotations checks against the resolved image for an annotation. All conditions must match.
	MatchImageAnnotations []ValueCondition
}

ImageCondition defines the conditions for matching a particular image source. The conditions below are all required (logical AND). If Reject is specified, the condition is false if all conditions match, and true otherwise.

func (*ImageCondition) DeepCopy

func (in *ImageCondition) DeepCopy() *ImageCondition

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new ImageCondition.

func (*ImageCondition) DeepCopyInto

func (in *ImageCondition) DeepCopyInto(out *ImageCondition)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type ImageExecutionPolicyRule

type ImageExecutionPolicyRule struct {
	ImageCondition

	// Reject means this rule, if it matches the condition, will cause an immediate failure. No
	// other rules will be considered.
	Reject bool
}

ImageExecutionPolicyRule determines whether a provided image may be used on the platform.

func (*ImageExecutionPolicyRule) DeepCopy

func (in *ImageExecutionPolicyRule) DeepCopy() *ImageExecutionPolicyRule

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new ImageExecutionPolicyRule.

func (*ImageExecutionPolicyRule) DeepCopyInto

func (in *ImageExecutionPolicyRule) DeepCopyInto(out *ImageExecutionPolicyRule)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type ImagePolicyConfig

type ImagePolicyConfig struct {
	metav1.TypeMeta

	// ResolveImages indicates what kind of image resolution should be done.  If a rewriting policy is chosen,
	// then the image pull specs will be updated.
	ResolveImages ImageResolutionType

	// ResolutionRules allows more specific image resolution rules to be applied per resource. If
	// empty, it defaults to allowing local image stream lookups - "mysql" will map to the image stream
	// tag "mysql:latest" in the current namespace if the stream supports it. The default for this
	// field is all known types that support image resolution, and the policy for those rules will be
	// set to the overall resolution policy if an execution rule references the same resource.
	ResolutionRules []ImageResolutionPolicyRule

	// ExecutionRules determine whether the use of an image is allowed in an object with a pod spec.
	// By default, these rules only apply to pods, but may be extended to other resource types.
	ExecutionRules []ImageExecutionPolicyRule
}

ImagePolicyConfig is the configuration for controlling how images are used in the cluster.

func (*ImagePolicyConfig) GetObjectKind

type ImageResolutionPolicyRule

type ImageResolutionPolicyRule struct {
	// Policy controls whether resolution will happen if the rule doesn't match local names. This value
	// overrides the global image policy for all target resources.
	Policy ImageResolutionType
	// TargetResource is the identified group and resource. If Resource is *, this rule will apply
	// to all resources in that group.
	TargetResource metav1.GroupResource
	// LocalNames will allow single segment names to be interpreted as namespace local image
	// stream tags, but only if the target image stream tag has the "resolveLocalNames" field
	// set.
	LocalNames bool
