Hi, I have following setup: Windows 10 machine I host Rancher v2.5.17 on (requirement to the OS and version) 5x RPi 4 B with Ubuntu 22.04 LTS 64-bit OS, hosting k3s cluster I want to import the cluster to Rancher. K3s installation works fine, but I'm struggling to install rancher/rancher-agent:v2.5.17-linux-arm64 and import the cluster to Rancher. I do the following: • Modify win firewall to accept inbound TCP connections on ports 8080 and 8443 • install rancher with: ◦ docker run --privileged -d --restart=always -p 8080:80 -p 8443:443 rancher/rancher:v2.5.17 • paste generated command to pull yaml file and apply it on the controller node • in the cluster API I set "agentImageOverride" to ARM64 image: rancher/rancher-agent:v2.5.17-linux-arm64 Result: • cluster in Rancher is kept in the "Pending" state • cattle agent pod doesn't get to ready state and keeps restarting and failing • running following command: ◦ kubectl describe pod [cattle cluster agent pod] -n cattle-system • gives me the output: ◦ Events: ◦ Type Reason Age From Message ◦ ---- ------ ---- ---- ------- ◦ Normal Scheduled 9m29s default-scheduler Successfully assigned cattle-system/cattle-cluster-agent-c4d59f4cb-slmmk to rpi3 ◦ Normal Pulling 9m29s kubelet Pulling image "rancher/rancher-agent:v2.5.17-linux-arm64" ◦ Normal Pulled 4m56s kubelet Successfully pulled image "rancher/rancher-agent:v2.5.17-linux-arm64" in 4m33.244685709s ◦ Normal Created 4m56s kubelet Created container cluster-register ◦ Normal Started 4m55s kubelet Started container cluster-register ◦ Warning Unhealthy 3m19s (x22 over 4m53s) kubelet Readiness probe failed: Get "http://10.42.0.14:8080/health": dial tcp 10.42.0.14:8080: connect: connection refused Does anyone know why the connection gets refused and how to workaround it? Any help highly appreciated. Thanks! Oskar

You shouldn't have to modify the agent image tag. It will work as-is. Are there any abnormal logs in from the Rancher agent pods?

In logs it was about missing secret/CA certs. But actually the information I don't have to modify the image tag for ARM lead me step by step to working import. So thank you a lot for this hint!
