    can anyone provide any input on how to access the rancher desktop dashboard on RHEL when using the AppImage? Rancher desktop comes up fine but how-tos all say to access the dashboard through the menu tray which doesn't appear to be populated when going the AppImage route (I see the dashboard icon on windows no problem). If anyone is aware how to launch the dashboard from command line or other suggestions it would be a huge help Thanks!

    I’m trying to create RKE Kubernetes cluster with the help of vSphere provider and using a preconfigured node template. When Rancher creates the VM nodes on VMware environment, I need them to have unique hostnames and IP’s. The problem is that the nodes are provisioned simultaneously from the template in vSphere and at first power-on, they couldn't get IP address and just power on! One strange thing is that if I deploy a new VM from this template manually on vCenter, it works fine and get IP !! I need the nodes to be configured with unique hostnames and IP’s. How do I fix this issue?

    This simple configuration doesn't work in Rancher 1. Started 1 deployment with this config 2. Increased the pods in the container to 3 3. The files created in
    /data
    are NOT shared between the 3 containers I do not want to use persistent volume claims because I don't need them to be persistent, I just need a folder to shared data ONLY between the pods in a deployment and for that data to be destroyed when the deployment is deleted

    Trying to track down a memory leak type of problem. Have a large cluster - 4 CP nodes, 5 ETCD Nodes, 360 Worker nodes. Workloads are constantly being re-deployed so workloads and configmaps are in the 15,000-25,000 range. ETCD has auto-compact every 30 min. No matter how big we make the instance sizes on ETCD, one random node (not the leader) out of 5 constantly increases its memory load until it runs out, while the other 4 stay in a reasonable low percentage resource utilization. Thoughts?

    So, has anyone had the issue where telling the helm chart to use external TLS termination on an L7 loadbalancer fails with k3s, because the rancher helm chart uses nginx ingress annotations, but k3s by default uses traefik 2 for ingress, so you still get the 302 redirect to https on port 80?

    None of my kubectl commands seem to be working after a default installation of Rancher Desktop 1.6.1 (command again from the Rancher Desktop VM). ~ # kubectl get pods I1031 17:24:41.453584 8798 versioner.go:58] invalid configuration: no configuration has been provided The connection to the server localhost:8080 was refused - did you specify the right host or port?

    What's a similarly easy alternative to Boot2Docker, where I can just have Rancher install the VM for me instead of handcrafting a VM template? With Boot2Docker, I'm getting
    Get <https://nexus.company.tld:8444/v2/>: x509: certificate has expired or is not yet valid
    when trying to access anything with letsencrypt certs, probably because Boot2Docker was last updated before letsencrypt switched certs.

    Hey there! I am trying to install Rancher in our cluster and we have several alarms created by security department. One of them is being triggered:
    user system:anonymous was granted API permissions on the EKS cluster aus-platform-core | default service account in EKS Cluster aus-platform-core was granted admin privileges by user system😒erviceaccount:cattle-system:rancher
    Is there anyway to avoid "system:anonymous" get admin privileges from rancher account?

    Folks - regarding Rancherd - is this still considered a "best practices" method of installing RKE2? The blog has you using https://get.rancher.io. Looking at the GitHub repo - https://github.com/rancher/rancherd - there doesn't appear to be a lot of activity and in fact the get rancher installer doesn't really look simpler than the RKE2 installer at: https://get.rke2.io ... Further, the get rke2 installer supports air-gapped installs where the get rancher installer does not. Finally, the hardcoded v2.5 channel in the get rancher installer installs kubernetes 1.20 which is fairly old at this point. So it almost seems like the get rancher installer is like a "beta" that evolved into get.rke2.io ... Any guidance? Thank you.
