Seems there's issue using location with some versions. The following was tested successfully on EKS cluster.

Install basic ingress-nginx on EKS:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.0/deploy/static/provider/aws/deploy.yaml

Note: If your cluster version is < 1.21, you need to comment out ipFamilyPolicy and ipFamilies in the service spec.

Run a http service:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/docs/examples/http-svc.yaml

Create an ingress for the service:

kubectl versions Error: exec plugin is configured to use API version client.authentication.k8s.io/v1alpha1

I was setting up my new Mac for my eks environment. After the installation of kubectl, aws-iam-authenticator and the kubeconfig file placement in default location. I ran the command kubectl command and got this error mentioned below in command block.

My cluster uses v1alpha1 client auth api version so basically i wanted to use the same one in my Mac as well.

I tried with latest version (1.23.0) of kubectl as well, still the same error. Whereas When i tried to do with aws-iam-authenticator (version 0.5.5) I was not able to download lower version.

Can someone help me to resolve it?

Answered 2022-Mar-28 at 09:41

I have the same problem

You're using aws-iam-authenticator 0.5.5, AWS changed the way it behaves in 0.5.4 to require v1beta1.

It depends on your configuration, but you can try to change the K8s context you're using to v1beta1

Otherwise switch back to aws-iam-authenticator 0.5.3 - you might need to build it from source if you're using the M1 architecture as there's no darwin-arm64 binary built for it

A CrashloopBackOff means that you have a pod starting, crashing, starting again, and then crashing again.

Maybe the error come from the application itself that it can not connect to database, redis,...

ANSWER

Answered 2022-Feb-16 at 01:33

You will have to persists the heap dumps on a shared network location between the pods. In order to achieve this, you will need to provide persistent volume claims and in EKS, this could be achieved using an Elastic File System mounted on different availability zones. You can start learning about it by reading this guide about EFS-based PVCs.

How to expose a service to outside Kubernetes cluster via ingress?

Asked 2021-Nov-27 at 09:36

I'm struggling to expose a service in an AWS cluster to outside and access it via a browser. Since my previous question haven't drawn any answers, I decided to simplify the issue in several aspects.

First, I've created a deployment which should work without any configuration. Based on this article, I did

kubectl create namespace tests
created file probe-service.yaml based on paulbouwer/hello-kubernetes:1.8 and deployed it kubectl create -f probe-service.yaml -n tests:

Well, I haven't figured this out for ArgoCD yet (edit: figured, but the solution is ArgoCD-specific), but for this test service it seems that path resolving is the source of the issue. It may be not the only source (to be retested on test2 subdomain), but when I created a new subdomain in the hosted zone (test3, not used anywhere before) and pointed it via A entry to the load balancer (as "alias" in AWS console), and then added to the ingress a new rule with / path, like this:

EKS Ingress with Single ALB, multiple namespaces, and External DNS

Asked 2021-Nov-16 at 19:58

I'm trying to configure a single ALB across multiple namespaces in aws EKS, each namespace has its own ingress resource.

I'm trying to configure the ingress controller aws-loadbalancer-controller on a k8s v1.20.

The problem i'm facing is that each time I try to deploy a new service it always spin-up a new classic loadbalancer in addition to the shared ALB specified in the ingress config.

ANSWER

Answered 2021-Sep-22 at 19:55

Unfortunately the tool being used for your usecase is wrong. AWS Load Balancer Controller will create a new load balancer for every ingress resource and I think, it makes a network load balancer for every service resource.

For your use-case, the best option is to use nginx ingress controller. You can deploy the nginx ingress controller in any 1 namespace and then create ingress resources throughout your cluster and you can have path/hostname based routing across your cluster.

In case you have many teams/projects/applications and you want to avoid a single point of failure where all your apps depend on 1 ELB, you can deploy more than 1 nginx ingress controller in your k8s cluster.

You just need to define a ingress-class variable in your nginx ingress controller deployment and add that ingress-class annotation on your applications. This way, applications having ingress-class:nginxA annotation will be clustered with the nginx ingress controller that has ingress-class=nginxA in its deployment.

Use Paketo.io / CloudNativeBuildpacks (CNB) in GitLab CI with Kubernetes executor & unprivileged Runners (without pack CLI & docker)

Asked 2021-Nov-15 at 14:04

We want to use Paketo.io / CloudNativeBuildpacks (CNB) GitLab CI in the most simple way. Our GitLab setup uses an AWS EKS cluster with unprivileged GitLab CI Runners leveraging the Kubernetes executor. We also don't want to introduce security risks by using Docker in our builds. So we don't have our host’s /var/run/docker.sock exposed nor want to use docker:dind.

We found some guides on how to use Paketo with GitLab CI like this https://tanzu.vmware.com/developer/guides/gitlab-ci-cd-cnb/ . But as described beneath the headline Use Cloud Native Buildpacks with GitLab in GitLab Build Job WITHOUT Using the GitLab Build Template, the approach relies on Docker and pack CLI.
