(aws-eks): kubectl layer is not compatible with k8s v1.22.0 #19843

akefirad · 2022-04-10T09:47:52Z

Describe the bug

Running an empty update on an empty EKS cluster fails while updating the resource EksClusterAwsAuthmanifest12345678 (Custom::AWSCDK-EKS-KubernetesResource).

Expected Behavior

The update should succeed.

Current Behavior

It's fails with error:

Received response status [FAILED] from custom resource. Message returned: Error: b'configmap/aws-auth configured\nerror: error retrieving RESTMappings to prune: invalid resource extensions/v1beta1, Kind=Ingress, Namespaced=true: no matches for kind "Ingress" in version "extensions/v1beta1"\n' Logs: /aws/lambda/InfraMainCluster-awscdkawseksKubec-Handler886CB40B-rDGV9O3CyH7n at invokeUserFunction (/var/task/framework.js:2:6) at processTicksAndRejections (internal/process/task_queues.js:97:5) at async onEvent (/var/task/framework.js:1:302) at async Runtime.handler (/var/task/cfn-response.js:1:1474) (RequestId: acd049fc-771c-4410-8e09-8ec4bec67813)

Reproduction Steps

This is what I did:

Deploy an empty cluster:

export class EksClusterStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props: cdk.StackProps) {
    super(scope, id, props);

    const clusterAdminRole = new iam.Role(this, "ClusterAdminRole", {
      assumedBy: new iam.AccountRootPrincipal(),
    });

    const vpc = ec2.Vpc.fromLookup(this, "MainVpc", {
      vpcId: "vpc-1234567890123456789",
    });

   const cluster = new eks.Cluster(this, "EksCluster", {
      vpc: vpc,
      vpcSubnets: [{ subnetType: ec2.SubnetType.PRIVATE_WITH_NAT }],
      clusterName: `${id}`,
      mastersRole: clusterAdminRole,
      defaultCapacity: 0,
      version: eks.KubernetesVersion.V1_22,
    });

    cluster.addFargateProfile("DefaultProfile", {
      selectors: [{ namespace: "default" }],
    });
  }
}

Add a new fargate profile

    cluster.addFargateProfile("IstioProfile", {
      selectors: [{ namespace: "istio-system" }],
    });

Deploy the stack and wait for the failure.

Possible Solution

No response

Additional Information/Context

I checked the version of kubectl in the lambda handler and it's 1.20.0 which AFAIK is not compilable with cluster version 1.22.0. I'm not entirely sure how the lambda is created. I thought it matches the kubectl with whatever version the cluster has. ~~But it seems it's not~~ It is not the case indeed (#15736).

CDK CLI Version

2.20.0 (build 738ef49)

Framework Version

No response

Node.js Version

v16.13.0

OS

Darwin 21.3.0

Language

Typescript

Language Version

3.9.10

Other information

Similar to #15072?

@akefirad Yesterday I had the same issue. As a temporary solution, you can create your own lambda layer version and pass it as a parameter to the Cluster construct. Here is my solution in python. It's just a combination of AwsCliLayer and KubectlLayer

My code building layer.zip every synth, but you can build it once you need it and save layer.zip in your repository.

assets/kubectl-layer/build.sh

#!/bin/bash
set -euo pipefail

cd $(dirname $0)

echo ">> Building AWS Lambda layer inside a docker image..."

TAG='kubectl-lambda-layer'

docker build -t ${TAG} .

echo ">> Extrating layer.zip from the build container..."
CONTAINER=$(docker run -d ${TAG} false)
docker cp ${CONTAINER}:/layer.zip layer.zip

echo ">> Stopping container..."
docker rm -f ${CONTAINER}
echo ">> layer.zip is ready"

assets/kubectl-layer/Dockerfile

# KUBECTL_VERSION should not be changed at the moment, see https://github.com/aws/aws-cdk/issues/15736
# Version 1.21.0 is not compatible with version 1.20 (and lower) of the server.

@peterwoodworth Check out commit message on #20000. After talking this over with Rico we've decided that it's a much greater effort, thus it would break backward compatibility with <1.21. LMKWYT.

peterwoodworth · 2022-04-26T18:30:34Z

I thought this would get auto closed once #20000 was merged 😅

No reason to keep this issue open with #20000 merged I think. Thanks for the ping

Linking aws/containers-roadmap#1595... EKS v1.23 k8s support is coming in August.

chlunde · 2022-05-25T08:59:23Z

FYI, a workaround is to set Prune to false. This of course has some side effects, but you can mitigate that by ensuring there's only one kubernetes object per manifest.

Solution is announced for Mid-September, see this issue.

PavanMudigondaTR · 2022-10-22T15:37:43Z

Have been struggling with this error for the last two days! Just today noticed this issue log. I would appreciate if AWS can provide solution. for mean time i will destroy my 1.23 stack and deploy with 1.21. I hope that works !

leadelngalame1611 · 2022-10-25T06:57:20Z

Hitting the same issue. Can anyone from AWS please tell us when this issue will be resolved? Since we upgraded EKS to version 1.22.0 we have been facing this issue. The workaround by @chlunde works well but not on all cases. Currently we cannot create new Nodegroups because these requires an update of the aws-auth resource which keeps failing with an error message

Received response status [FAILED] from custom resource. Message returned: Error: b'configmap/aws-auth configured\nerror: error retrieving RESTMappings to prune: invalid resource extensions/v1beta1, Kind=Ingress, Namespaced=true: no matches for kind "Ingress" in version "extensions/v1beta1"\n' Logs: /aws/lambda/InfraMainCluster-awscdkawseksKubec-Handler886CB40B-rDGV9O3CyH7n at invokeUserFunction (/var/task/framework.js:2:6) at processTicksAndRejections (internal/process/task_queues.js:97:5) at async onEvent (/var/task/framework.js:1:302) at async Runtime.handler (/var/task/cfn-response.js:1:1474) (RequestId: acd049fc-771c-4410-8e09-8ec4bec67813)

currently we are blocked and can't proceed with our deployment.

I have used the instructions posted by @Obirah and that works so far. See here

cgarvis · 2022-10-27T03:41:07Z

Release this week should have a way to use an updated kubectl layer.

leadelngalame1611 · 2022-10-27T06:46:17Z

@cgarvis Thank you for the update. We are waiting impatiently for the Release.

rhyswilliamsza · 2022-11-01T11:09:59Z

Hello

I see 1.23 support has been merged! 🎉 Thanks for the effort there.

Re: KubectlV23Layer - is this still an experimental feature? We'd like to implement a V1_23 kubectl layer using the java edition, however this doesn't seem possible at this stage?

neptune19821220 · 2022-11-01T15:53:34Z

Hello,

Thank you for the new release to support EKS 1.23.

But when I deploy the stack to create EKS 1.23, I got the warning:

You created a cluster with Kubernetes Version 1.23 without specifying the kubectlLayer property. 
This may cause failures as the kubectl version provided with aws-cdk-lib is 1.20, 
which is only guaranteed to be compatible with Kubernetes versions 1.19-1.21. 
Please provide a kubectlLayer from @aws-cdk/lambda-layer-kubectl-v23.

Then I try to follow the document:

import { KubectlV23Layer } from 'aws-cdk-lib/lambda-layer-kubectl-v23';

const cluster = new eks.Cluster(this, 'hello-eks', {
  version: eks.KubernetesVersion.V1_23,
  kubectlLayer: new KubectlV23Layer(this, 'kubectl'),
});

But there seems no package lambda-layer-kubectl-v23 under aws-cdk-lib v2.50.0.
Is lambda-layer-kubectl-v23 available now?

Hi, you need to add the package @aws-cdk/lambda-layer-kubectl-v23 to your (dev) dependencies and import the layer from that package.

neptune19821220 · 2022-11-02T03:23:32Z

Thank you for your help.
It works now.

There is a separate module you need to install aws-cdk.lambda-layer-kubectl-v23 then you can import from aws_cdk import lambda_layer_kubectl_v23

Thanks @jaredhancock31 ! This helped me a lot. ^_^

If anyone needs it, here is my example implementation in Go that I tweaked using the original cdk init file go-cdk.go, and with the suggestion above to upgrade a cluster I was experimenting with.

complete code here: https://gist.github.com/andrewbulin/e23c313008372d4e5149899817bebe32

snippet here:

	cluster := awseks.NewCluster(
		stack,
		jsii.String("UpgradeMe"),
		&awseks.ClusterProps{
			Version:      awseks.KubernetesVersion_V1_22(),
			KubectlLayer: kubectlv22.NewKubectlV22Layer(stack, jsii.String("kubectl")),
			ClusterName:  jsii.String("upgrade-me"),
			ClusterLogging: &[]awseks.ClusterLoggingTypes{
				awseks.ClusterLoggingTypes_AUDIT,
