What works for us is enabling Proxy Protocol V2 (manually) for the NLB's Target Group and then configuring nginx-ingress to use the real-ip-header from the proxy protocol. Note: You must first configure the monitor with ‘nlb-dns-monitor-configure’. Health Checks failed outside of ingress controller AWS NLB. It happens if the name of the node the pod residing is different to the Linux hostname. Couple that with anti-affinity for the ingress pods based on AZ and it works really well. ¨é›†ã®è¨­å®š] ページで、必要に応じて設定を変更し、[変更内容の保存] を選択します。, 古いコンソールを使用してターゲットグループのヘルスチェック設定を変更するには, [Health checks]、[Edit] を選択します。, [Edit target group] ページで、必要に応じて設定を変更し、[Save] を選択します。, AWS CLI を使用してターゲットグループのヘルスチェック設定を変更するには, modify-target-group コマンドを使用します。, ブラウザで JavaScript が無効になっているか、使用できません。, AWS ドキュメントを使用するには、JavaScript を有効にする必要があります。手順については、使用するブラウザのヘルプページを参照してください。, ページが役に立ったことをお知らせいただき、ありがとうございます。, お時間がある場合は、何が良かったかお知らせください。今後の参考にさせていただきます。, このページは修正が必要なことをお知らせいただき、ありがとうございます。ご期待に沿うことができず申し訳ありません。, お時間がある場合は、ドキュメントを改善する方法についてお知らせください。, このページは役に立ちましたか? TCP ingress controller is failing while installing cloudera datascience workbench, i can see below in logs any suggestions please... The activity history is quite active due to instances failing the ELB health check. Sadly we can't externalTrafficPolicy: "Cluster" since we need the client ip address forwarded to our application, for now we work-around this issue by using nginx-ingress as daemonset and static healthCheckNodePort for each of the nginx-ingresses. Think, I've found out why: externalTrafficPolicy: "Local" Setting externalTrafficPolicy: "Cluster" does not work as well . End result is a DNS lookup returning white-listable EIPs for those AZs that have active ingress controllers., passing client IPs on to pods. Verify that your instance is failing health checks and then check for the following: A security group does not allow traffic The security groups associated with an instance must allow traffic from the load balancer using the health check port and health check protocol. Final piece of the puzzle is registering nodes in the target groups, which we take care of using an autoscaling groups for the ingress nodes. 受け取ったエラーについて、以下の手順に従います。 AWS NLB to ECS Cluster failing health check - Stack Overflow Health Details: However, eventually the health check on the NLB fails, the containers are drained and new container replace them. You basically just manage the EIP-NLB bits yourself and just expose the NodePort. )手動で対象から除外と追加を行う必要がある 2.指定したHealth Checkのアクセス先がリダイレクトだったかでダメだった … Thank you @yashwanthkalva, those steps will make it work.

We had to manually configure NLBs pointing to NodePort services to make it work with health checks, so it is possible. After making the changes above all nodes now report healthy in the Target Group (even though we're only running nginx on a subset of those nodes) and we are seeing the correct source IP in nginx access logs. I have been struggling with that for one day now, don't know where to look anymore. When you create a load balancer, you define a health check and the success status code for your service. I do have exactly the same conf in another cluster and it does work fine. Having the same issue, but with multiple services using the LoadBalancer type with Classic and NLB on AWS EKS. Windows NLB is great feature for network load balancing, it has not evolved much since windows 2000 days and it does not address above questions directly. I'm facing the same issues as stated in the issue description, could anyone help me in resolving this. https://aws.amazon.com/blogs/opensource/network-load-balancer-nginx-ingress-controller-eks/ Using Windows 10 This thread is locked.

And unfortunately, the tooltip does not provide much help by returning me a message of "Health … @mariusmarais so just ensuring each node has a controller running didn't work for you? Another thing to note. Once you've set it to Local, you can't simply change it back Cluster without completely removing and re-creating the service and NLB. I checked the NLB created, target groups and healthcheck, everything is fine, the issue is only with the healthcheck within the node and the svc/pod. Looking forward to a structural solution. Then hook up an NLB target group for each of those, using a TCP healthcheck to the traffic port. ロードバランサの重要な3つの機能 ロードバランサには色々な機能があります。また、ロードバランサがシングルの場合と冗長化の場合とでは 使用する機能も大きく異なってきます。ここではシングル構成や冗長化構成に関係なく、ロードバランサ導入 2019-09-07 13:42:15.381 1 INFO TCPIngress Start connecting to Operator GRPC endpoint data = {"endpoint":"ds-operator.default.svc.cluster.local:80"} I changed this: externalTrafficPolicy: "Cluster" and had to redeploy the Service.

It’s important to recognize that ExternalTrafficPolicy is not a way to preserve source IP; it’s a change in networking policy that happens to preserve source IP. to your account. You signed in with another tab or window. I experienced the same problem (with CLB) and found the cause, thanks to #80579. Does not work on Kubernetes v1.17. 以降 … https://aws.amazon.com/blogs/opensource/network-load-balancer-nginx-ingress-controller-eks/ This is because I use the one health check across multiple clients, and HTTP/1.1 would require me to include a host header, eg: HEAD / HTTP/1.1 Host: shaun.net Connection: close Using HTTP/1.0 (which does not support virtual hosts) eliminates this requirement and makes using a single check for many different clients much easier. To make public NLB work with ingress controller, Spent hours on this yesterday - same issue as well - new EKS 1.14 cluster. The HTTP target group health check is fine, however, the HTTPS target group health check is not. Application Load Balancer をトラブルシューティングし、ヘルスチェックの失敗を修正するには: 1. Image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.24.1. How to reproduce it (as minimally and precisely as possible): EKS cluster 1.13, Amazon Linux EKS optimized nodes, deploy nginx ingress with helm with the values above. How else can you preserve source IP with Kubernetes? I was randomly checking out the EKS EC2 nodes and found this behaviour. こんにちは、技術4課の多田です。 私事ですが、サーバーワークスに入社して1年が経ちました。本当にあっという間でしたが、入社前後での自分のスキルアップを実感した1年でした。2年目も引き続き頑張っていこうと思います。 さて、今回は、Application Load Balancer(以下、ALB)に関する豆 … こんにちは、Bogartです。 Classic Load Balancer (CLB) , Application Load Balancer (ALB)に次ぐ新たなロードバランサとして、 Network Load Balancer (NLB)がリリースされました!

The text was updated successfully, but these errors were encountered: Comment /remove-triage unresolved when the issue is assessed and confirmed. If you are using a Layer 4 load balancer, you can use the PROXY protocol. After struggling with this issue for an inordinate amount of time, I think I finally found a solution that allows us to use externalTrafficPolicy=Cluster (and thereby avoid the problems in this issue and others) while still preserving source IP. We want to track the unhealthy host count because it tells us if a service is failing its health check. It should be possible to have both source IP and health checks. It started working for me. If you are exposing an API through the ELB, or you have a health check running on a different port, you have the option to select a different protocol, port, and path for that health check. @greywolve No, running everything everywhere wouldn't work for us. By default if you set the health check to “HTTPS” it’ll check 443. externalTrafficPolicy in the ingress controller manifest needs to be changed from "Local" to "Cluster". We did this to use EIPs with NLBs before Kubernetes supported it. Already on GitHub? Actually, I found some logs, some errors came in few days after the deployment. I have an ALB that mananges at least two instances at any given time. Check the health of your target to find the reason code and description of your issue. It started working for me. We just need it to also work when setup automatically. NLB はステートレスなことを確認するのに役立ちますインターネット インフォメーション サービスを実行する web サーバーなどのアプリケーション (IIS), 、最小限のダウンタイムで利用できるとはスケーラブルな (負荷の増加に応じて追加のサーバーを追加することで)します。NLB is useful for ensuring that stateless applications, such as web servers running Internet Information Services (IIS), are available with minimal downtime, and that they are scalable (by adding additional servers as the load increases). Send feedback to sig-testing, kubernetes/test-infra and/or fejta. For example, if you have a redirection from HTTP:80 to HTTPS:443 on the backend, then HTTP health checks on port 80 will fail, unless you change the health check to HTTPS and health check … If you need 8443, I recommend a TCP health check on 8443 (not HTTPS). I also confirm that this solution doesn't work with Kubernetes v1.17. For ingress specifically we want only a subset of nodes to host the port. exactly the same issue on EKS 1.14, with Nginx IC 0.26.1 . We installed with the official Helm chart: Chart version: 1.6.18 Does anyone have a solution yet ? The ec2-Instance's are listed in the load balancer in the console but they keep failing the health check. Rotten issues close after an additional 30d of inactivity. Remember to open up those ports on the nodes' security groups and perhaps lower the healthcheck thresholds. 2019-09-07 13:42:16.385 1 INFO TCPIngress Start connecting to Web GRPC endpoint data = {"endpoint":"web.default.svc.cluster.local:20050"}, I0907 08:54:25.224473 14295 kubelet.go:1953] SyncLoop (PLEG): "ds-reconciler-64bccdd574-gsrnm_default(3b9aada8-d0d3-11e9-91b7-005056b6dc19)", event: &pleg.PodLifecycleEvent{ID:"3b9aada8-d0d3-11e9-91b7-005056b6dc19", Type:"ContainerDied", Data:"06759c56d143925a01cf39a68ec9d41c6dfeb7df5bacee6e99f34bb75a2be760"} We should get 200 responce on this endpoint. On NLB side, health checks are failing. Looking forward to a better solution with externalTrafficPolicy: "Local". externalTrafficPolicy in the ingress controller manifest needs to be changed from "Local" to "Cluster" and (externalTrafficPolicy: Cluster instead of Local does ''solve'' the issue but with the indicated side effects. We are experiencing the same issue. To make public NLB work with ingress controller, externalTrafficPolicy in the ingress controller manifest needs to be changed from "Local" to "Cluster" Only then NLB target groups health checks will pass. Successfully merging a pull request may close this issue. Send feedback to sig-testing, kubernetes/test-infra and/or fejta. Have a question about this project? The timeout value, health check interval, and threshold can be adjusted to match the needs of your application, and all can be edited at a later time to better tune the health check for optimal performance. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Mark the issue as fresh with /remove-lifecycle rotten. Also built a new 1.13 cluster - same behavior with nginx ingress + NLB. or is that not what you want? However, the current behaviour is a bug. /lifecycle rotten, Following the steps here, Thanks! This by default sets up the HTTP healthcheck on a random port unless: If controller.service.type is NodePort or LoadBalancer and controller.service.externalTrafficPolicy is set to Local, set this to the managed health-check port the kube-proxy will expose. Annual health checks in Japan have their obvious benefits, but there's more than meets the eye from a cultural and business perspective. Now the healthcheck is configured with a TCP port and I get healthy targets. /lifecycle stale. To troubleshoot and fix failing health checks for your Application Load Balancer: 1. privacy statement. 続々とELBに機能が追加されていますが、今更ですがNLBについて書きます。 今更NLBの記事を書くことに意味があるのか?と自問しましたが、一応 (初心者向け) と (HealthCheck) という切り口で、なるべく優しく書こうと思います。 1.14 cluster with Nginx 0.26.1 - well if the controller is deployed to all nodes, then it is okay. https://github.com/helm/charts/tree/master/stable/nginx-ingress, https://aws.amazon.com/blogs/opensource/network-load-balancer-nginx-ingress-controller-eks/, https://kubernetes.io/docs/tasks/access-application-cluster/create-external-load-balancer/#preserving-the-client-source-ip. I had originally changed the externalTrafficPolicy to Local in order to preserve source IP. To debug further I created a test ec2-Instance (54.68.255.208) through the console with a security group that allows connections from anywhere in the world on any port. In addition, you can use ELB’s health checks in conjunction with Amazon’s Auto Scaling service to ensure that instances that repeatedly fails healthy checks with a … 2019-09-07 13:42:15.381 1 INFO TCPIngress Finish reading config It is correct that setting the policy is meant to change the loadbalancing itself but additionally it is officially documented to set this policy to preserve the source ip: https://kubernetes.io/docs/tasks/access-application-cluster/create-external-load-balancer/#preserving-the-client-source-ip.
