L2 Construct

KubernetesManifest

Represents a manifest within the Kubernetes system. Alternatively, you can use `cluster.addManifest(resource[, resource, ...])` to define resources on this cluster. Applies/deletes the manifest using `kubectl`.

Import

import { KubernetesManifest } from 'aws-cdk-lib/aws-eks';

Or use the module namespace:

import * as eks from 'aws-cdk-lib/aws-eks';
// eks.KubernetesManifest

Properties

Configuration passed to the constructor as KubernetesManifestProps.

clusterRequired
ICluster

The EKS cluster to apply this manifest to. [disable-awslint:ref-via-interface]

manifestRequired
{ [key: string]: any }[]

The manifest to apply. Consists of any number of child resources. When the resources are created/updated, this manifest will be applied to the cluster through `kubectl apply` and when the resources or the stack is deleted, the resources in the manifest will be deleted through `kubectl delete`.

overwriteOptional
boolean

Overwrite any existing resources. If this is set, we will use `kubectl apply` instead of `kubectl create` when the resource is created. Otherwise, if there is already a resource in the cluster with the same name, the operation will fail.

Default: false

5 properties inherited from KubernetesManifestOptions
ingressAlbOptionalinherited from KubernetesManifestOptions
boolean

Automatically detect `Ingress` resources in the manifest and annotate them so they are picked up by an ALB Ingress Controller.

Default: false

ingressAlbSchemeOptionalinherited from KubernetesManifestOptions
AlbScheme

Specify the ALB scheme that should be applied to `Ingress` resources. Only applicable if `ingressAlb` is set to `true`.

Default: AlbScheme.INTERNAL

pruneOptionalinherited from KubernetesManifestOptions
boolean

When a resource is removed from a Kubernetes manifest, it no longer appears in the manifest, and there is no way to know that this resource needs to be deleted. To address this, `kubectl apply` has a `--prune` option which will query the cluster for all resources with a specific label and will remove all the labeld resources that are not part of the applied manifest. If this option is disabled and a resource is removed, it will become "orphaned" and will not be deleted from the cluster. When this option is enabled (default), the construct will inject a label to all Kubernetes resources included in this manifest which will be used to prune resources when the manifest changes via `kubectl apply --prune`. The label name will be `aws.cdk.eks/prune-<ADDR>` where `<ADDR>` is the 42-char unique address of this construct in the construct tree. Value is empty.

Default: - based on the prune option of the cluster, which is `true` unless otherwise specified.

removalPolicyOptionalinherited from KubernetesManifestOptions
RemovalPolicy

The removal policy applied to the custom resource that manages the Kubernetes manifest. The removal policy controls what happens to the resource if it stops being managed by CloudFormation. This can happen in one of three situations: - The resource is removed from the template, so CloudFormation stops managing it - A change to the resource is made that requires it to be replaced, so CloudFormation stops managing it - The stack is deleted, so CloudFormation stops managing all resources in it

Default: RemovalPolicy.DESTROY

skipValidationOptionalinherited from KubernetesManifestOptions
boolean

A flag to signify if the manifest validation should be skipped.

Default: false
