Recently we did OS patched on our DEV 3 node kube cluster and after that we are unable to see that cluster in rancher UI. Before patching it was there and was working fine

hey guys, how do I protect cluster from deletion? due to crazy bug that rancher sometimes just deletes managed clusters when cluster configuration is changed using terraform provider https://github.com/rancher/rancher/issues/38833 I want somehow to protect clusters from accidental delete

Hi Everyone, I have some issues currently after updating to Rancher 2.6.8 where I cannot exec to any pods:

$ kubectl exec -it my-pod -- sh
Error from server:

after debugging with

kubectl -v=7 exec -it my-pod -- sh

I saw:

I0914 13:35:16.704958   79032 round_trippers.go:457] Response Status: 403 Forbidden in 95 milliseconds
I0914 13:35:16.705922   79032 helpers.go:216] server response object: [{
  "metadata": {}
}]

so it seems there is some premission issue even though i am the cluster admin. I just upgraded Rancher and decided to setup a cert-manager Certificate with istio:

apiVersion: <http://networking.istio.io/v1beta1|networking.istio.io/v1beta1>
kind: Gateway
metadata:
  name: rancher
  namespace: cattle-system
spec:
  selector:
    app: istio-ingressgateway
  servers:

        name: https
        protocol: HTTPS
      hosts:
      - <http://rancher.example.com|rancher.example.com>
      tls:
        mode: SIMPLE
        credentialName: <http://rancher.example.com|rancher.example.com>
---
apiVersion: <http://networking.istio.io/v1beta1|networking.istio.io/v1beta1>
kind: VirtualService
metadata:
  name: rancher
  namespace: cattle-system
spec:
  gateways:
  - rancher
  hosts:
  - <http://rancher.example.com|rancher.example.com>
  http:
  - name: "http"
    route:
    - destination:
        host: rancher.cattle-system.svc.cluster.local
        port:
          number: 80

Is there is something missing from my part?

Hi there After doing a restore of a snapshot the cluster went into unavailable state and the error is

Rancher v2.6.8 - K8s v1.24.2

Can anyone help?

Good Morning Everyone, I asked this the other day is there a repository/chart for images used on ARM processors (Raspberry Pi's) I don't seem to be able to get anything to work on the 2 Kubernetes clusters which are microk8s driven on Ubuntu Server 20.04.5 but for the ARM?

What k8s distro is it? RKE2? Did you add it with a registration command?

Hello. I am getting started with using Rancher CD, I decided to go with Rancher instead of Argo for its multi-cluster approach. I am looking for documentation specifically about the CD feature of Rancher but I cant find it. Anyway can point me in the right direction? I am using Rancher 2.6.8

you mean fleet.rancher.io

Hi, What is the correct helm chart repository url for charts like here: https://github.com/rancher/system-charts/tree/release-v2.7/charts/rancher-monitoring? I want to try deploy monitoring stuff by regular helm not via web ui or rke api.

Any plans to support Rancher import existing EKS cluster using IAM roles instead of access and secret key? Or is there a way to for when Rancher leaves in Kubernetes to select a service account to do the import?

Is it possible to un-register an AWS EKS cluster from Rancher? What if the cluster was imported and not created with Rancher?

Hello, I am trying to use rancher 2.6.8, Running directly on EKS. Replacing existing EC2 running docker .... and rancher. I am having an issue with webhooks and see message Internal error occurred: failed calling webhook "rancherauth.cattle.io": Post "https://rancher-webhook.cattle-system.svc:443/v1/webhook/validation?timeout=10s": Address is not allowed

👋 Hi everyone!

is officially supported and production ready the rancher installation in k3s with 3 nodes and embedded etcd as backend ?

Hi, where can i verify the SHA256 of all rancher images?

In the old monitoring I was able to setup grafana.extraVars[0].name GF_INSTALL_PLUGINS and values for it, to preinstall grafana plugins. How this can be done for grafana in monitoring v2?

What

max surge

in Scaling/Upgrade policy means ?

Hi, how can I replace Docker Desktop with Rancher Desktop in windows (with WSL)? Actually, after installing the RD in my Windows I can not see my old docker images which were created with Docker Desktop. Thx

Is there an rsync service for rpm.rancher.io? I'd like to mirror the k3s packages to a repo in my network. (It's something that I've done for an openSUSE mirror)

Hi there

Any reason in particular that when I create a new custom cluster within Rancher (single node docker) that the new cluster get's stuck in reconciling during the creation of the cluster?

Hello dears, i hope you can support me on this issue, I am doing a performance test to an application running in a single pod using jmeter. Increasing the number of requests per 60 seconds showed the expected result that CPU consumption gets higher and so on. Then i decided to scale up the application to 2 replicas, the expected result that the performance will be much better, but unfortunately a lot of requests failed and the CPU consumption got really high! so i scaled down the app to 1 replica as it was before, and the results were good with no failed requests at all! Note: pods are running on different node with same number of cores and same processor and ram...

What is the correct process to override the rke2 encryption configuration? After using systemctl start rke2-server.service, I then disabled the secrets-encrypt, then used crictl to stop the container, then tried to use "rke2 server --kube-apiserver-arg=encryption-provider-config=/var/lib/rancher/rke2/server/cred/secrets-encrypt.yaml" however the server fails to start again.

It's possible to let rke2 work node join a k3s node? for two reasons: 1. rke2 have some default pods I do not need. 2. rke2 support windows.

Hello, I am looking some help for Rancher. I have upgraded my kubernetes cluster nodes to RHEL 8.6 and after upgrade cluster is not working and in Rancher dashboard it keeps on showing "Agent is not connected". I am using Rancher v2.6.8 Please advise me for this issue.

Hi all, we are unable to connect to Bitbucket private repository with Rancher continuous delivery. We keep getting “Invalid credentials fatal: Authentication”

Hi there, is it possible (Rancher 2.6.4) to have helm catalog at "project" level ?

To clarify, at this time we can only add Helm registry at the cluster level. But I need users to be able to add their own helm registry for their own projects

(and because the documentation is done... I can't check)
