    k3s docker image comes without 
    curl
    . Busybox 
    wget
    can't download using https. How to download files inside k3s docker container? https://hub.docker.com/r/rancher/k3s

    Is it possible to run k3s without certificates? Its running on a isolated vm on an internal network on prem. Would like to avoid certs so the k3s doesn’t just stop working after a while

    I found this script certs.sh in the k3s github repo. It seems to create ssl certs in the tls folder. The script seems to indicate that its -days 7300 nr of days before expire. If i run this script then i would not need to bother with ssl cert rotation right? (its running within an isloated environment). . Given that i run this before k3s i started.

    I am having trouble installing k3s on a 4 node (1 master 3 workers) raspberry pi cluster running 64 bit pi os (Debian Bullseye) and I was able to fix the master install by enabling cgroups via adding 
    cgroup_memory=1 cgroup_enable=memory
    to 
    /boot/cmdline.txt
    but I am running into an issue with the worker nodes not able to join the cluster with a worker role. I run the following command on the worker nodes:
    Copy code
    curl -sfL <https://get.k3s.io> | K3S_URL=<https://rpi-kube-master-01:6443> K3S_TOKEN=<token> sh -
    I can 
    curl
    the api server just fine from the worker nodes to validate iptables/nftables aren’t an issue. I have also removed them via 
    sudo apt remove iptables -y && sudo apt install nftables
    How can I further troubleshoot how to fix this issue with worker nodes joining with no roles?

    Hi there! A very specific question: Has anyone tried to run a k3s cluster with (some) worker nodes spread over the internet? AFAIK, there are a lot of constraints around latency, packet loss, a.s.o; I am unsure if that's something that is potentially solved already

    Anyone have any pointers to using traefik with k3s/k3d/k0s on WSL-2? I have a cluster setup using k3s and was going through the class Master Traefik Proxy with K3s - Traefik Academy and was able to access Traefik using port forwarding but am having problems accessing the cluster with an ingress kubectl get ingress -A -o wide NAMESPACE NAME CLASS HOSTS ADDRESS PORTS AGE kube-system traefik-dashboard traefik dashboard.traefik.10.43.0.1.sslip.io 172.19.216.155 80 37m Anyone have any pointers on how to debug?

    Have question about automated upgrades for k3s.... from this document https://docs.k3s.io/upgrades/automated I can specify channel and cluster is always automatically upgraded to the newest stable release of K3s. Is there a way to do n-2? Or perhaps only way to do that is to specify specific release like in example provided on same document above? Not sure if it matters, but I have HA cluster with etcd. running k3s version 1.22.9

    k3s 
    docker-compose.yml
    creates many unnamed volumes, that don't get removed on 
    docker compose down --volumes
    . Is this related to btrfs?

    I recreated the docker-compose k3s cluster completely from scratch. After a few restarts I get 
    503 Service Unavailable
    and some pods are 
    Terminating
    forever. What am I doing wrong?

    Hi everyone! I need to deploy K3s in rootless mode (security reasons) and I'm facing a lot of problems making it work as should be. Anyone tried to have a K3s rootless working on production despite being an experimental feature?

    I know the HA setup. But if I have 4 nodes(3 servers + 1 agent) in total: I would love to be able to shut off 3 of them and have only 1 running and my applications to all still be running normally even if a bit slower. But there's no way to do this with HA obviously. I was thinking the other day, couldn't I just create individual clusters on each machine, and have my applications running on all of them? and that way I could be able to shut off 3 machines and my applications technically would still be running?

    Could this be caused by an automatic traefik update? I did `kubectl cluster-info dump`` and found
    Copy code
    + echo 'Upgrading traefik'

+ helm_v3 upgrade --set-string global.systemDefaultRegistry= traefik <https://10.43.0.1:44>

    Every server restart leads to 
    PR_END_OF_FILE_ERROR
    in the browser. Is there an alternative to 
    docker-compose
    ?

    Hi all, I have two machines and both are configured seperately (with k3s) as masters. Now I need to combine these two into one cluster, having both as masters (for high availability). Is this possible and can you please explain the steps to achive this. Thanks Pai

    Hi folks! I've been trying to set up k3s on a few spare machines running in my homelab. 1 control-plane node and 2 agent nodes. k3s & flannel start just fine, and the agent nodes can join the cluster just fine. However, pods can't route out of their network, even to the kubernetes API. i'm at a loss as to why that may be the case, can someone help me troubleshoot what's going on?

    Hi… in the default installation of k3s, where is the public repository/images located ? Eg when i run “kubectl run nginx --image=nginx …“, where is k3s pulling the ‘nginx’ from ?

    Hey guys, I am having trouble with a lot of pods. New pods fail, k3s journal shows a lot of this: 
    "Error syncing pod, skipping" err="failed to \"StartContainer\" for \"local-path-provisioner\" with CrashLoopBackOff: \"back-off 2m40s restarting failed container=local-path-provisioner pod=local-path-provisioner-79f67d76f8-pbmcw_kube-system(270760c4-931f-4a6e-8a78-cd3166a50248)\"" pod="kube-system/local-path-provisioner-79f67d76f8-pbmcw" podUID=270760c4-931f-4a6e-8a78-cd3166a50248
    any idea what might be the root issue?

    well, pod’s logs show this:
    Copy code
    kubectl logs -f local-path-provisioner-79f67d76f8-pbmcw -n ku
be-system
time="2023-03-02T14:52:34Z" level=fatal msg="Error starting daemon: Cannot start Provisioner: failed to get Kubernetes server version: Get \"<https://10.43.0.1:443/version?timeout=32s>\": dial tcp 10.43.0.1:443: connect: no route to host"
    deleting the pod and waiting for it to be recreated “fixes” the problem
