Functions

func Resource 

func Resource(resource string) schema.GroupResource

Resource takes an unqualified resource and returns a Group qualified GroupResource

Types

type AuditAnnotation 

type AuditAnnotation struct {

	// key specifies the audit annotation key. The audit annotation keys of a ValidatingAdmissionPolicy must be unique. The key must be a qualified name ([A-Za-z0-9][-A-Za-z0-9_.]*) no more than 63 bytes in length.
	//
	// The key is combined with the resource name of the ValidatingAdmissionPolicy to construct an audit annotation key: "{ValidatingAdmissionPolicy name}/{key}".
	//
	// If an admission webhook uses the same resource name as this ValidatingAdmissionPolicy and the same audit annotation key, the annotation key will be identical. In this case, the first annotation written with the key will be included in the audit event and all subsequent annotations with the same key will be discarded.
	//
	// Required.
	// Required: true
	Key *string `json:"key"`

	// valueExpression represents the expression which is evaluated by CEL to produce an audit annotation value. The expression must evaluate to either a string or null value. If the expression evaluates to a string, the audit annotation is included with the string value. If the expression evaluates to null or empty string the audit annotation will be omitted. The valueExpression may be no longer than 5kb in length. If the result of the valueExpression is more than 10kb in length, it will be truncated to 10kb.
	//
	// If multiple ValidatingAdmissionPolicyBinding resources match an API request, then the valueExpression will be evaluated for each binding. All unique values produced by the valueExpressions will be joined together in a comma-separated list.
	//
	// Required.
	// Required: true
	ValueExpression *string `json:"valueExpression"`
}

AuditAnnotation AuditAnnotation describes how to produce an audit annotation for an API request.

type MatchCondition 

type MatchCondition struct {

	// Documentation on CEL: https://kubernetes.io/docs/reference/using-api/cel/
	//
	// Required.
	// Required: true
	Expression *string `json:"expression"`

	// Name is an identifier for this match condition, used for strategic merging of MatchConditions, as well as providing an identifier for logging purposes. A good name should be descriptive of the associated expression.

	// matchPolicy defines how the "MatchResources" list is used to match incoming requests. Allowed values are "Exact" or "Equivalent".
	//
	// - Exact: match a request only if it exactly matches a specified rule. For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1, but "rules" only included `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]`, a request to apps/v1beta1 or extensions/v1beta1 would not be sent to the ValidatingAdmissionPolicy.

For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1, and "rules" only included `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]`, a request to apps/v1beta1 or extensions/v1beta1 would be converted to apps/v1 and sent to the ValidatingAdmissionPolicy.

	// For example, to run the webhook on any objects whose namespace is not associated with "runlevel" of "0" or "1";  you will set the selector as follows: "namespaceSelector": {

Use the object selector only if the webhook is opt-in, because end users may skip the admission webhook by setting the labels. Default to the empty LabelSelector, which matches everything.
