Different resource types may have different constraints on names (`metadata.name`). The previous version of the name generator was compatible with DNS_SUBDOMAIN but not with DNS_LABEL. For example, `Deployment` names must comply with DNS_SUBDOMAIN while `Service` names must comply with DNS_LABEL. Since there is no formal specification for this, the default name generation scheme for kubernetes objects in cdk8s was changed to DNS_LABEL, since it’s the common denominator for all kubernetes resources (supposedly). You can override this method if you wish to customize object names at the chart level. ###### `apiObject`Required <a name="apiObject" id="cdk8s.Chart.generateObjectName.parameter.apiObject"></a> - *Type:* <a href="#cdk8s.ApiObject">ApiObject</a> The API object to generate a name for. --- ##### `toJson` <a name="toJson" id="cdk8s.Chart.toJson"></a> ```typescript public toJson(): any[] ``` Renders this chart to a set of Kubernetes JSON resources. #### Static Functions <a name="Static Functions" id="Static Functions"></a> | **Name** | **Description** | | --- | --- | | <code><a href="#cdk8s.Chart.isConstruct">isConstruct</a></code> | Checks if `x` is a construct. | | <code><a href="#cdk8s.Chart.isChart">isChart</a></code> | Return whether the given object is a Chart. | | <code><a href="#cdk8s.Chart.of">of</a></code> | Finds the chart in which a node is defined. | --- ##### ~~`isConstruct`~~ <a name="isConstruct" id="cdk8s.Chart.isConstruct"></a> ```typescript import { Chart } from 'cdk8s' Chart.isConstruct(x: any) ``` Checks if `x` is a construct. ###### `x`Required <a name="x" id="cdk8s.Chart.isConstruct.parameter.x"></a> - *Type:* any Any object. --- ##### `isChart` <a name="isChart" id="cdk8s.Chart.isChart"></a> ```typescript import { Chart } from 'cdk8s' Chart.isChart(x: any) ``` Return whether the given object is a Chart.

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.

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. > [https://kubernetes.io/docs/concepts/overview/working-with-objects/finalizers/](https://kubernetes.io/docs/concepts/overview/working-with-objects/finalizers/) --- ##### `labels`Optional <a name="labels" id="cdk8s.ApiObjectMetadata.property.labels"></a> ```typescript public readonly labels: {[ key: string ]: string}; ``` - *Type:* {[ key: string ]: string} - *Default:* No labels.

You can supply custom name allocation logic by overriding the `chart.generateObjectName` method.
