Cloud Development Kit for Kubernetes

build npm version PyPI version Maven Central

cdk8s is a software development framework for defining Kubernetes applications using rich object-oriented APIs. It allows developers to leverage the full power of software in order to define abstract components called "constructs" which compose Kubernetes resources or other constructs into higher-level abstractions.

Note: This repository is the "core library" of cdk8s, with logic for synthesizing Kubernetes manifests using the constructs framework. It is published to NPM as cdk8s and should not be confused with the cdk8s command-line tool cdk8s-cli. For more general information about cdk8s, please see cdk8s.io, or visit the umbrella repository located at cdk8s-team/cdk8s.

Generates a unique and stable name compatible label key name segment and label value from a path.

The name segment is required and must be 63 characters or less, beginning and ending with an alphanumeric character ([a-z0-9A-Z]) with dashes (-), underscores (_), dots (.), and alphanumerics between.

Valid label values must be 63 characters or less and must be empty or begin and end with an alphanumeric character ([a-z0-9A-Z]) with dashes (-), underscores (_), dots (.), and alphanumerics between.

The generated name will have the form: 

<comp0><delim><comp1><delim>..<delim><compN><delim><short-hash>

Types

type ApiObject 

type ApiObject interface {
	constructs.Construct
	// The group portion of the API version (e.g. `authorization.k8s.io`).
	ApiGroup() *string
	// The object's API version (e.g. `authorization.k8s.io/v1`).
	ApiVersion() *string
	// The chart in which this object is defined.
	Chart() Chart
	// The object kind.
	Kind() *string
	// Metadata associated with this API object.
	Metadata() ApiObjectMetadataDefinition
	// The name of the API object.
	//
	// If a name is specified in `metadata.name` this will be the name returned.
	// Otherwise, a name will be generated by calling
	// `Chart.of(this).generatedObjectName(this)`, which by default uses the
	// construct path to generate a DNS-compatible name for the resource.
	Name() *string
	// The tree node.
	Node() constructs.Node
	// Create a dependency between this ApiObject and other constructs.
	//
	// These can be other ApiObjects, Charts, or custom.
	AddDependency(dependencies ...constructs.IConstruct)
	// Applies a set of RFC-6902 JSON-Patch operations to the manifest synthesized for this API object.
	//
	// Example:
	//     kubePod.addJsonPatch(JsonPatch.replace('/spec/enableServiceLinks', true));
	//
	AddJsonPatch(ops ...JsonPatch)
	// Renders the object to Kubernetes JSON.
	//
	// To disable sorting of dictionary keys in output object set the
	// `CDK8S_DISABLE_SORT` environment variable to any non-empty value.
	ToJson() interface{}
	// Returns a string representation of this construct.
	ToString() *string
}

func ApiObject_Of 

func ApiObject_Of(c constructs.IConstruct) ApiObject

Returns the `ApiObject` named `Resource` which is a child of the given construct.

If `c` is an `ApiObject`, it is returned directly. Throws an exception if the construct does not have a child named `Default` _or_ if this child is not an `ApiObject`.

func NewApiObject 

func NewApiObject(scope constructs.Construct, id *string, props *ApiObjectProps) ApiObject

Defines an API object.

type ApiObjectMetadata 

type ApiObjectMetadata struct {
	// Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata.
	//
	// They are not queryable and should be
	// preserved when modifying objects.
	// See: http://kubernetes.io/docs/user-guide/annotations
	//
	Annotations *map[string]*string `field:"optional" json:"annotations" yaml:"annotations"`
	// Namespaced keys that tell Kubernetes to wait until specific conditions are met before it fully deletes resources marked for deletion.
	//
	// Must be empty before the object is deleted from the registry. Each entry is
	// an identifier for the responsible component that will remove the entry from
	// the list. If the deletionTimestamp of the object is non-nil, entries in
	// this list can only be removed. Finalizers may be processed and removed in
	// any order.  Order is NOT enforced because it introduces significant risk of
	// stuck finalizers. finalizers is a shared field, any actor with permission
	// can reorder it. If the finalizer list is processed in order, then this can
	// lead to a situation in which the component responsible for the first
	// finalizer in the list is waiting for a signal (field value, external
	// system, or other) produced by a component responsible for a finalizer later
	// in the list, resulting in a deadlock. Without enforced ordering finalizers
	// are free to order amongst themselves and are not vulnerable to ordering
	// changes in the list.
	// See: https://kubernetes.io/docs/concepts/overview/working-with-objects/finalizers/
	//
	Finalizers *[]*string `field:"optional" json:"finalizers" yaml:"finalizers"`
	// Map of string keys and values that can be used to organize and categorize (scope and select) objects.
	//
	// May match selectors of replication controllers and services.
	// See: http://kubernetes.io/docs/user-guide/labels
	//
	Labels *map[string]*string `field:"optional" json:"labels" yaml:"labels"`
	// The unique, namespace-global, name of this object inside the Kubernetes cluster.
	//
	// Normally, you shouldn't specify names for objects and let the CDK generate
	// a name for you that is application-unique. The names CDK generates are
	// composed from the construct path components, separated by dots and a suffix
	// that is based on a hash of the entire path, to ensure uniqueness.
	//
	// You can supply custom name allocation logic by overriding the
	// `chart.generateObjectName` method.
	//
	// If you use an explicit name here, bear in mind that this reduces the
	// composability of your construct because it won't be possible to include
	// more than one instance in any app. Therefore it is highly recommended to
	// leave this unspecified.
	Name *string `field:"optional" json:"name" yaml:"name"`
	// Namespace defines the space within each name must be unique.
	//
	// An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation.
	// Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty. Must be a DNS_LABEL. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/namespaces
	Namespace *string `field:"optional" json:"namespace" yaml:"namespace"`
	// List of objects depended by this object.
	//
	// If ALL objects in the list have
	// been deleted, this object will be garbage collected. If this object is
	// managed by a controller, then an entry in this list will point to this
	// controller, with the controller field set to true. There cannot be more
	// than one managing controller.
	//
	// Kubernetes sets the value of this field automatically for objects that are
	// dependents of other objects like ReplicaSets, DaemonSets, Deployments, Jobs
	// and CronJobs, and ReplicationControllers. You can also configure these
	// relationships manually by changing the value of this field. However, you
	// usually don't need to and can allow Kubernetes to automatically manage the
	// relationships.
	// See: https://kubernetes.io/docs/concepts/overview/working-with-objects/owners-dependents/
	//
	OwnerReferences *[]*OwnerReference `field:"optional" json:"ownerReferences" yaml:"ownerReferences"`
}

Metadata associated with this object.

type ApiObjectMetadataDefinition 

type ApiObjectMetadataDefinition interface {
	// The name of the API object.
	//
	// If a name is specified in `metadata.name` this will be the name returned.
	// Otherwise, a name will be generated by calling
	// `Chart.of(this).generatedObjectName(this)`, which by default uses the
	// construct path to generate a DNS-compatible name for the resource.
	Name() *string
	// The object's namespace.
	Namespace() *string
	// Adds an arbitrary key/value to the object metadata.
	Add(key *string, value interface{})
