Implements IConstruct, IDependable, IKubectlProvider

Implementation of Kubectl Lambda.

Example

const handlerRole = iam.Role.fromRoleArn(this, 'HandlerRole', 'arn:aws:iam::123456789012:role/lambda-role');
// get the serivceToken from the custom resource provider
const functionArn = lambda.Function.fromFunctionName(this, 'ProviderOnEventFunc', 'ProviderframeworkonEvent-XXX').functionArn;
const kubectlProvider = eks.KubectlProvider.fromKubectlProviderAttributes(this, 'KubectlProvider', {
  serviceToken: functionArn,
  role: handlerRole,
});

const cluster = eks.Cluster.fromClusterAttributes(this, 'Cluster', {
  clusterName: 'cluster',
  kubectlProvider,
});

---

cluster🔹

Type: ICluster

The cluster to control.

---

kubectlLayer🔹

Type: ILayerVersion

An AWS Lambda layer that includes kubectl and helm.

---

awscliLayer?🔹

Type: ILayerVersion (optional)

An AWS Lambda layer that contains the aws CLI.

If not defined, a default layer will be used containing the AWS CLI 2.x.

---

environment?🔹

Type: { [string]: string } (optional)

Custom environment variables when running kubectl against this cluster.

---

memory?🔹

Type: Size (optional)

The amount of memory allocated to the kubectl provider's lambda function.

---

privateSubnets?🔹

Type: ISubnet[] (optional)

Subnets to host the kubectl compute resources.

If not specified, the k8s endpoint is expected to be accessible publicly.

---

role?🔹

Type: IRole (optional, default: if not specified, the default role created by a lambda function will be used.)

An IAM role that can perform kubectl operations against this cluster.

The role should be mapped to the system:masters Kubernetes RBAC role.

This role is directly passed to the lambda handler that sends Kube Ctl commands to the cluster.

---

securityGroup?🔹

Type: ISecurityGroup (optional, default: If not specified, the k8s endpoint is expected to be accessible publicly.)

A security group to use for kubectl execution.

Properties

Name	Type	Description
node🔹	Node	The tree node.
