    Hey all, We would like to add a custom tolerations in cattle-cluster-agent deployment for a user added taint in node, so we are exactly hitting this issue - https://github.com/rancher/rancher/issues/16050 Saw the work around :
    An empty key with operator Exists matches all keys, values and effects which means this will tolerate everything.
    tolerations:
    - operator: "Exists"
    and
    kubectl -n cattle-system patch ds/cattle-node-agent -p '{"spec":{"template":{"spec":{"tolerations":[{"operator":"Exists"}]}}}}'
    do you think that the first code snippet can be added to the cattle-cluster-agent deployment manifest or it will work only with kubectl patch? We would like to make this persist with code. Please let us know if we really can add a toleration to cattle-cluster-agent deployment manifest, thank you 🙇

    Hello there! I'm trying to configure cloud-config on rancher to use with vsphere Most things work but I can't set my specific network configuration I tried pasting this into the Node Template Cloud-config box and also into an extra parameter called
    guestinfo.metadata
    base64 encoded with
    guestinfo.metadata.encoding: base64
    as well as
    gzip+base64
    network:
      version: 2
      ethernets:
        nics:
          match:
            name: ens*
          dhcp4: yes
          critical: true
          dhcp-identifier: mac
    Testing it on vSphere directly works, but with Rancher it does not What am I missing?

    Is there a way to use Node Profiles to deploy k3s/rke2 just like we do in rke1? It's much easier than having to change (cloud-config for example) in a single profile instead of in each machine pool

    rancher 2.6.9, trying to install cert-manager 1.10.1 from jetstacks repo using the UI on a GKE cluster. Server Version: version.Info{Major:"1", Minor:"24", GitVersion:"v1.24.7-gke.900", GitCommit:"e35c4457f66187eff006dda6d2c0fe12144ef2ec", GitTreeState:"clean", BuildDate:"2022-10-26T09:25:34Z", GoVersion:"go1.18.7b7", Compiler:"gc", Platform:"linux/amd64"} 1.10.1 CRDs applied to the cluster ahead of time. This is the values.yml: installCRDs: false replicaCount: 3 extraArgs: - --dns01-recursive-nameservers=1.1.1.1:53,9.9.9.9:53 - --dns01-recursive-nameservers-only podDnsPolicy: None podDnsConfig: nameservers: - "1.1.1.1" - "9.9.9.9" installs fine using helm3 from my workstation. Any ideas? Would love to have helm installs appear in the UI for a visual representation of any charts that are updated in their respective repositories.

    Hi all, I'm having issues with metrics and I can't find anything helpful online. I have a cluster with 3 etcd + control plane nodes and 4 workers. Docker 20.10.21, Kubernetes 1.24.6, Rancher 2.6.9. Everything was fine in the beginning, but after a few days, one after the other, nodes stopped reporting metrics. Some are still working, but I'm sure that if I leave them long enough, they will stop too. The metrics server reports:
    Failed to scrape node" err="Get \"https://***:10250/metrics/resource\": context deadline exceeded" node="node-that-stopped-reporting"
    kubectl top node shows:
    node-that-stopped-working <unknown> <unknown> <unknown> <unknown>
    HPAs are not working because of this, and I'm not sure what other issues this could cause. If I restart the node, the reporting starts working again for a few days, and then it stops. The machines are powerful enough and this problem started when the cluster was still empty, so I doubt is resources-related. Even now that the cluster is running some workloads, there are pleny of resources available. I have no idea what could cause this, but I noticed something interesting:
    kubectl get --raw /api/v1/nodes/$NODE_NAME/proxy/stats/summary
    takes a really long time (~2 minutes) on those nodes that don't work, while it's fast (~2 seconds) on a working node. Any kind of help is greatly appreciated!

    Did anyone manage to create a StatefulSet using the Rancher API but also setting the serviceName? No matter what I try, the ServiceName is always null. If I do it from the UI, it works. If I copy the payload from the UI and try it in the API, the service name is still null

    Hello we are using Rancher to manage EKS clusters.. we are now looking into managing EKS-D. We have been reading a lot about RKE vs RKE2 (RKE2 seems to be ideal for managing EKS-D) .. We are trying to understand do we use the RKE2 install to create a cluster and Rancher still can manage it? Or do we need to run a whole new install for Rancher with RKE2 https://docs.rke2.io/install/quickstart#server-node-installation <-- this documentation seems to describe that RKE2 has its own separate server node therefore new rancher has to be installed? Documentation seems to not be complete or unclear Sources: https://docs.rke2.io/install/quickstart and https://docs.ranchermanager.rancher.io/pages-for-subheaders/installation-and-upgrade Any information would be helpful!

    Hi all, after upgrading to rancher 2.6.9 and for the downstream cluster kubernetes 1.24.7 (stable), we found an issue for creating snapshots. The error pattern is similar to this scenario*:* https://github.com/rancher/rancher/issues/39605 The only difference is that we do not store snapshots in S3, but store them locally on the respective host and then save them centrally in NFS. In Rancher Management you see them at "0 bytes"size. It seems to be just a permission problem in Rancher, so it can't read the locally stored files, for example. In the pod "rke2-etcd-snapshots" on rachner cluster we found an error form snapshot handler like is: "error while receiving cluster local from cache via index: Index with name by-cluster does not exisit, requeuing ..." Does anyone have any ideas on how to fix this?

    Hi all, We have a 12 nodes (bare-metal) cluster using rke2. During the weekend, we lost 1 node and lost the connection with Rancher UI. I was able to find, that from the cluster end, there are 2 hooks into rancher, but I haven’t been able to find hooks on rancher. - Rancher UI runs in a 3 node (VMs) cluster. After discarding everything I could think of, my theory is that from rancher there was only 1 hook/connection point. Is that the case? If so, where can I find it? (what sort of resource is it and in which ns runs). If not, any theory of why 1 node down would disconnect the cluster from Rancher UI? Thanks!
