    I have setup Container registry (Harbor). I have installed with certificates signed by CA. I am able to connect using a browser and the certificate is valid, but docker daemon was giving x509 error. For now I have resolved this by modify the daemon.json to accept the insecure connection. However when I try to add the charts repository to rancher it's giving an error: Get "https://harbor.mysite.com/harbor/projects/3/helm-charts/index.yaml": x509: certificate signed by unknown authority. Any suggestion on how I can get rancher to also accept the connection to the charts repo?

    I have setup a HA rancher cluster and couple of downstream clusters. I need to relocate the servers and want to bring down the system in an orderly manner and then bring it backup again. Is there an order in which this should be done such as shutting down the downstream cluster VMs first and then the Rancher cluster VMs? Should I take snapshots of the downstream clusters first so if anything goes wrong I can revert to the snapshot?

    👋 Hello, team! I just took over an old Rancher server setup at the office and I made the mistake of version upgrading to Ubuntu 22.04, after that kube/k3s broke. Eventually I gave up on repairing it and re-installed k3s on the server (over the previous setup) but now my problem is all the old rancher container are missing 😞 From what I can see it looks like containerd has moved /var/lib/rancher/k3s/agent/containerd/ <> /run/k3s/containerd/. Im not very confident about my logic here and so before I start doing real damage to my server I wanted to check with you guys and see if you can point me the right direction.

    Has anybody had success in trying the new Rancher setup AMI image? I’ve tried it a couple times and have run into problems. I get the system spun up, and logged in. But every step in the wizard gives an error. I can’t seem to find if there are minimum VM requirements or network setup.

    Hi Everyone! Not sure if this would be the best place to ask these questions but I'm having an issue with Rancher and the UI. After some exploring it looks like I might be missing the install of Rancher or something close to that. I can't find the Rancher pods running anywhere on my cluster. I have a number of apps running in different namespaces and can't resolve any of them. I guess there was an activity that messed up the underlying IP addresses on the VMs running. This all got fixed and re-configured but now for some reason I'm missing the Rancher UI and the apps running in separate namespaces can't be accessed. I keep receiving a 504 bad gateway error. I can get more details tomorrow if someone is in the America time zone? Really strange issue...

    For rke2 and rancher v2.7, for production it is recommended between these alternatives: openSUSE Leap 15.4 CentOS 7.9 Rocky Linux 8.6 ubuntu 22.04 on aws ec2

    Hello all, I am in the process of installing Rancher and Rancher Desktop to learn some k8s concepts. I am following the instructions here: https://docs.rancherdesktop.io/how-to-guides/rancher-on-rancher-desktop and I am getting a 404 error message when I go to the IP address and nothing when I go to https://rancher.rd.localhost/ A couple of the pods in cattle-system had some restarts early on but haven't restarted for a while.

    I also have another question. If I build an image with the Rancher-Desktop ui, it doesn't show up when executing "docker ps" and when I build using the cli, it doesn't show up under the Rancher-Desktop list of images, you also can't use cli built images in kubectl deployments. Is there a flag or a way to import those into Rancher-Desktop?
