Functions

func ConfirmNoEscalation

func ConfirmNoEscalation(request *admission.Request, rules []rbacv1.PolicyRule, namespace string, ruleResolver validation.AuthorizationRuleResolver) error

ConfirmNoEscalation checks that the user attempting to create a binding/role has all the permissions they are attempting to grant.

func EscalationAuthorized

func EscalationAuthorized(request *admission.Request, gvr schema.GroupVersionResource, sar authorizationv1.SubjectAccessReviewInterface, namespace string) (bool, error)

EscalationAuthorized checks if the user associated with the context is explicitly authorized to escalate the given GVR.

func SetEscalationResponse

func SetEscalationResponse(response *admissionv1.AdmissionResponse, err error)

SetEscalationResponse will update the given webhook response based on the provided error from an escalation request.

func ToExtraString

func ToExtraString(extra map[string]authenticationv1.ExtraValue) map[string][]string

ToExtraString will convert a map of map[string]authenticationv1.ExtraValue to map[string]string.

Types

type RBACRestGetter

type RBACRestGetter struct {
	Roles               wranglerv1.RoleCache
	RoleBindings        wranglerv1.RoleBindingCache
	ClusterRoles        wranglerv1.ClusterRoleCache
	ClusterRoleBindings wranglerv1.ClusterRoleBindingCache
}

RBACRestGetter is used to encapsulate Getters for core RBAC resource types.

func (RBACRestGetter) GetClusterRole

func (r RBACRestGetter) GetClusterRole(name string) (*rbacv1.ClusterRole, error)

GetClusterRole gets the clusterRole with the given name.

func (RBACRestGetter) GetRole

func (r RBACRestGetter) GetRole(namespace, name string) (*rbacv1.Role, error)

GetRole gets role within the given namespace that matches the provided name.

func (RBACRestGetter) ListClusterRoleBindings

func (r RBACRestGetter) ListClusterRoleBindings() ([]*rbacv1.ClusterRoleBinding, error)

ListClusterRoleBindings list all clusterRoleBindings.

func (RBACRestGetter) ListRoleBindings

func (r RBACRestGetter) ListRoleBindings(namespace string) ([]*rbacv1.RoleBinding, error)

ListRoleBindings list all roleBindings in the given namespace.

type RoleTemplateResolver

type RoleTemplateResolver struct {
	// contains filtered or unexported fields
}

RoleTemplateResolver provides an interface to flatten role templates into slice of rules.

func NewRoleTemplateResolver

func NewRoleTemplateResolver(roleTemplates v3.RoleTemplateCache, clusterRoles v1.ClusterRoleCache) *RoleTemplateResolver

NewRoleTemplateResolver creates a newly allocated RoleTemplateResolver from the provided caches

func (*RoleTemplateResolver) RoleTemplateCache

func (r *RoleTemplateResolver) RoleTemplateCache() v3.RoleTemplateCache

RoleTemplateCache allows caller to retrieve the roleTemplateCache used by the resolver.

func (*RoleTemplateResolver) RulesFromTemplate

func (r *RoleTemplateResolver) RulesFromTemplate(roleTemplate *rancherv3.RoleTemplate) ([]rbacv1.PolicyRule, error)

RulesFromTemplate gets all rules from the template and all referenced templates.

func (*RoleTemplateResolver) RulesFromTemplateName

func (r *RoleTemplateResolver) RulesFromTemplateName(name string) ([]rbacv1.PolicyRule, error)

RulesFromTemplateName gets the rules for a roleTemplate with a given name. Simple wrapper around RulesFromTemplate.
