Hello! I'm trying to learn the ropes of Rancher and its capabilities and am curious about its relationship with Amazon EKS, specifically EKS distro/EKS anywhere. Is it possible to set up a cluster using rancher which is running on an on-prem EKS Anywhere/a using EKS distro as the Kubernetes distribution? From the research I've done so far it seems like it is possible but would be an unintended use of Rancher, is this true? Has anyone done this before? Thanks for any advice/clarification!

Hi there, I am working on on proof of concept and trying to deploy Rancher on top of AWS EKS following this documentation: https://ranchermanager.docs.rancher.com/getting-started/installation-and-upgrade/install-upgrade-on-a-kubernetes-cluster/rancher-on-amazon-eks. At step 6, I don't get an external-IP for the load balancer (it stays in <pending> ). Is there a step missing to integrate Rancher with AWS Load balancer ?

Is anyone aware of success, challenges, documentation around connecting to AWS hosted Prometheus/Grafana services natively today with Rancher?

Has anyone seen this error? I am using the Rancher MCM v2.7.2 to create an EKS cluster to another AWS account. "error retrieving resource lock kube-system/cloud-controller-manager: leases.coordination.k8s.io "cloud-controller-manager" is forbidden: User "eks:cloud-controller-manager" cannot get resource "leases" in API group "coordination.k8s.io" in the namespace "kube-system""

I'm using Rancher to manager a non-EKS EC2 cluster and things are mostly working, but load balancer target groups have no targets in them. I have no idea what is going wrong, how do I troubleshoot this?

@careful-appointment-9763: do you have deployed an ingress-nginx like stated in the documentation?

I'm using the AWS Load Balancer Controller and it is creating the AWS load balancer and target groups, but the target groups remain empty. I'm using Instance target type and have check the labels on the pods, nodes, and service annotations. I'm still not sure what I've missed

Hi guys, we are running Rancher

2.7.3

and would like to update our EKS Cluster to Kubernetes

1.25

. Actually when we go on Cluster Config to update Kubernetes, we can’t see

1.25

version on UI. Does anyone know why

1.25

is not appearing? Thanks in advance for your help!

Hi folks, the Rancher 2.7.3 support Matrix goes through EKS 1.24. Supporting up to 1.24 (N-2), when EKS is on 1.26 presents an interesting customer experience if we want folks managing EKS clusters with Rancher. Their default deployment version is 1.25 and will very shortly be 1.26. Our Marketplace offering deploys onto 1.23. I'm hoping the new MP offering will at least leverage 1.25 but should target 1.26 or we'll be outdated very quickly. Can I ask what the plans are for this offering? Posted in #rancher-setup

What happened in this dashboard before upgrading to 2.7.3? It is showing up pods information here, btw I'm using EKS 1.25

AWS CDK

ECR

Hey there! I am trying yo deploy a CDK stack that relies on ECR and thus is looking for a docker daemon. I only have rancher desktop installed and that has typically served me just fine when manually interacting with containers/ building images. But now I am wondering whether I absolutely need to install docker or whether there might be a workaround to use the rancher backend for this CDK deployment. Any experience with that?

Does anyone know of a guide that can walk us through setting up nvidia gpu's on suse rancher on aws ?

We're using it to test out Suse Rancher with some software we've built, but can't seem to get GPUs setup properly

hi there ! I could do with some help, I installed Rancher on top of EKS, then created a Custum cluster, ran the registration command, but the node is stuck in "[Waiting] configuring bootstrap node(s) custom-cc795ca87598: waiting for probes: kubelet". I ran "sudo journalctl -u rancher-system-agent.service -f" on the node, and it's displaying : "level=info msg="[K8s] updated plan secret fleet-default/custom-cc795ca87598-machine-plan with feedback". Any idea what the problem could be here ?

@careful-appointment-9763 i have been going through your slack messages in this group , wanted to check with you if you ever managed to get AWS LB working with K3s. I had the same issues like you mentioned with AWS Load Balancer Controller. What i want to achieve is having 3 K3s Nodes (on Ec2 Instance) and have 1 LB that i can controller from k3s using either nginx-ingress or traefik

Hi everyone, i have a problem with rancher and EKS imported cluster when they have custom CNI. I follow this issue resolution https://github.com/rancher/rancher/issues/41172 but in reality there are two things to do: the firt modify the rancher-webhook by adding the hostNetwork reference setted to true, and less in a minute update the rancher-webook chart beacuse rancher, otherwise, automatically rollback the rancher-webhook's deployment to previous configuration. Now i'm asking you if you know a way to performe the chnage on the rancher-webhook before the import of the cluster. Thanks

Are there any reasons to not add an AWS node to an existing cluster in my datacenter? Assume VPN tunnels are up, security groups are open, etc. Any problem with the VPN latency or nodes on a different subnet?

I would personally avoid long distance nodes in a cluster - any sort of network outage or MTU issue will cause issues for the cluster or a workload rebalance. There is also quite a bit of network traffic passed between worker nodes and controller nodes.

Now if you are referring to having the rancher install in your datacenter but building a cluster on AWS that it manages, that works just fine and I can tell you from experience that vpn tunnels are not required so long as the cluster can hit the rancher UI on https.

In this case we already have a huge production cluster in our datacenter and need to add GPU-driven application, but aren't ready yet to buy GPUs

How can I assign a fixed IP address to a pod? I'd like to simplify the networking for a VoIP application, preferably without a load balancer or layers of NAT. I'm using EKS and have the VPC CNI plugin

steep-postman-22406

07/28/2023, 7:12 PM

expose that pod service with an IP address and a port

careful-appointment-9763

07/28/2023, 9:51 PM

I need an IP that won't change if the pod changes nodes, and as a voip application I need to have a port range open for RTP streams.
