    Hi, is it possible to manually add nodes (for example - a manually provisioned bare-metal node) to a rancher-launched cluster?

    Hi guys, today I need your help I’ve deployed a RabbitMQ at Rancher and now I want to expose it through an Istio Ingress Gateway. I’ve deployed an Istio DestinationRule, Istio Gateway and an Istio Virtual Service, all pointing to the RabbitMQ Service. Also I’ve associated the worker IP address with an URL in AWS Route53. But when I get to that URL from the browser doesn’t get me anywhere. Also I did a curl -I MyURL and gives me a 404 Not Found (I port-forwarded the service and worked perfectly) Any suggestion/idea?

    hi everyone! I'm trying to import a generic cluster in rancher (2.6.8) but this downstream cluster and the local cluster are located in different places and each one is linked to his own registry. When i'm applying the yaml to deploy the agent on the downstream cluster, two options look wrong for my use case and i can't find a way to edit them: • the cluster-agent image, pulled from the registry related to my local cluster instead of the downstream 's one. • CATTLE_CLUSTER_REGISTRY, defined by a value from my rancher helm chart (systemDefaultRegistry). This settings are in my clusters.management.cattle.io crd but i can't edit them as this is somehow controlled by someting else

    Hi, I've got rancher manager set up with AD, but I have issues with users that are a member of a nested group outside the Group Search Base, they can't login. It seems as if the User Member Attribute (value: memberOf) doesn't get set every time, because I can't find it back in the variables and if I want to edit the config, the field shows empty. Does anybody recognize this problem?

    hello guys, We're not able to add new nodes to the cluster. The node appears in Registering state in Rancher UI and nothing happens after. in Rancher logs we have this

    Hey, am I understanding right that Rancher requires an IAM User to provision EKS clusters? Or is there a way to make it assume an IAM Role for those operations? Basing this question off what I'm reading here: https://docs.ranchermanager.rancher.io/pages-for-subheaders/amazon-eks-permissions

    I am having some trouble with a Rancher-managed RKE(1) cluster running on Harvester, provisioning fails to add new etcd-role members because it first tries to remove members that no longer exist (it already succeeded in removing them, but doesn’t seem to have noticed this, and just keeps trying). I can’t figure out where the state is that remembers that these members exist (they are no longer in the Rancher cluster as Machines or references in the ManagmentCluster, they are not in the managed cluster’s etcd, VMs are not in Harvester) such that it is trying to remove them.

    Good afternoon. I’m running into a problem in my cluster. 2 days ago my team tried to conduct an upgrade to 2.6.8. In the process it looks like a ClusterRolebinding called
    cattle-unauthenticated
    was created on the local cluster. This triggered some security alarm bells and I need to confirm whether or not it was us. I cannot find this in the helm chart so I’m wondering if an operator did this.

My problem is, that existing annotations from that upgrade prohibits an new upgrade rerun. Has anyone an good advise for me? (https://github.com/harvester/harvester/issues/2972). thanks in advance

    Hi! Anyone of you stumbled over those errors with an Rancher-created EKS Cluster? The AWS clusters are stable and I can create new clusters (even with same type and zone, named in the first message) and they won’t have this error message. Those errors are very sticky for months now and neither K8s (
    1.19
    -> `1.20`; triggered via Rancher) nor Rancher Update (
    Rancher 2.5.9
    -> `Rancher 2.6.7`; running on k3s) did solve this issue. Rancher is using
    rancher/eks-operator:v1.1.5
    to handle the AWS communication atm. Any ideas besides recreating the AWS clusters and migrate the workload? Do you think it’s worth opening an issue in the eks-operator project?
