Types

type Attributes

type Attributes interface {
	// GetUser returns the user.Info object to authorize
	GetUser() user.Info

	// GetVerb returns the kube verb associated with API requests (this includes get, list, watch, create, update, patch, delete, deletecollection, and proxy),
	// or the lowercased HTTP verb associated with non-API requests (this includes get, put, post, patch, and delete)
	GetVerb() string

	// When IsReadOnly() == true, the request has no side effects, other than
	// caching, logging, and other incidentals.
	IsReadOnly() bool

	// The namespace of the object, if a request is for a REST object.
	GetNamespace() string

	// The kind of object, if a request is for a REST object.
	GetResource() string

	// GetSubresource returns the subresource being requested, if present
	GetSubresource() string

	// GetName returns the name of the object as parsed off the request.  This will not be present for all request types, but
	// will be present for: get, update, delete
	GetName() string

	// The group of the resource, if a request is for a REST object.
	GetAPIGroup() string

	// GetAPIVersion returns the version of the group requested, if a request is for a REST object.
	GetAPIVersion() string

	// IsResourceRequest returns true for requests to API resources, like /api/v1/nodes,
	// and false for non-resource endpoints like /api, /healthz, and /swaggerapi
	IsResourceRequest() bool

	// GetPath returns the path of the request
	GetPath() string
}

Attributes is an interface used by an Authorizer to get information about a request that is used to make an authorization decision.

type AttributesRecord

type AttributesRecord struct {
	User            user.Info
	Verb            string
	Namespace       string
	APIGroup        string

	Subresource     string
	Name            string
	ResourceRequest bool
	Path            string
}

type Authorizer

type Authorizer interface {
	Authorize(a Attributes) (authorized Decision, reason string, err error)
}

Authorizer makes an authorization decision based on information gained by making zero or more calls to methods of the Attributes interface. It returns nil when an action is authorized, otherwise it returns an error.

type AuthorizerFunc

type AuthorizerFunc func(a Attributes) (Decision, string, error)

func (AuthorizerFunc) Authorize

func (f AuthorizerFunc) Authorize(a Attributes) (Decision, string, error)

type Decision

type Decision int
const (
	// DecisionDeny means that an authorizer decided to deny the action.
	DecisionDeny Decision = iota
	// DecisionAllow means that an authorizer decided to allow the action.
	DecisionAllow
	// DecisionNoOpionion means that an authorizer has no opinion on whether
	// to allow or deny an action.
	DecisionNoOpinion
)

type DefaultNonResourceRuleInfo

type DefaultNonResourceRuleInfo struct {
	Verbs           []string
	NonResourceURLs []string
}

DefaultNonResourceRuleInfo holds information that describes a rule for the non-resource

func (*DefaultNonResourceRuleInfo) GetNonResourceURLs

func (i *DefaultNonResourceRuleInfo) GetNonResourceURLs() []string

func (*DefaultNonResourceRuleInfo) GetVerbs

func (i *DefaultNonResourceRuleInfo) GetVerbs() []string

type DefaultResourceRuleInfo

type DefaultResourceRuleInfo struct {
	Verbs         []string
	APIGroups     []string
	Resources     []string
	ResourceNames []string
}

DefaultResourceRuleInfo holds information that describes a rule for the resource

func (*DefaultResourceRuleInfo) GetAPIGroups

func (i *DefaultResourceRuleInfo) GetAPIGroups() []string

func (*DefaultResourceRuleInfo) GetResourceNames

func (i *DefaultResourceRuleInfo) GetResourceNames() []string

func (*DefaultResourceRuleInfo) GetResources

func (i *DefaultResourceRuleInfo) GetResources() []string

func (*DefaultResourceRuleInfo) GetVerbs

func (i *DefaultResourceRuleInfo) GetVerbs() []string

type NonResourceRuleInfo

type NonResourceRuleInfo interface {
	// GetVerbs returns a list of kubernetes resource API verbs.
	GetVerbs() []string
	// GetNonResourceURLs return a set of partial urls that a user should have access to.
	GetNonResourceURLs() []string
}

type RequestAttributesGetter

type RequestAttributesGetter interface {
	GetRequestAttributes(user.Info, *http.Request) Attributes
}

RequestAttributesGetter provides a function that extracts Attributes from an http.Request

type ResourceRuleInfo

type ResourceRuleInfo interface {
	// GetVerbs returns a list of kubernetes resource API verbs.
	GetVerbs() []string
	// GetAPIGroups return the names of the APIGroup that contains the resources.
	GetAPIGroups() []string
	// GetResources return a list of resources the rule applies to.
	GetResources() []string
	// GetResourceNames return a white list of names that the rule applies to.
	GetResourceNames() []string
}

type RuleResolver

type RuleResolver interface {
	// RulesFor get the list of cluster wide rules, the list of rules in the specific namespace, incomplete status and errors.
	RulesFor(user user.Info, namespace string) ([]ResourceRuleInfo, []NonResourceRuleInfo, bool, error)
}

RuleResolver provides a mechanism for resolving the list of rules that apply to a given user within a namespace.
