I'm trying to create an HA k3s cluster using Proxmox and a small fleet of Raspberriy PIs 4B.
For the PIs everything works fine, but when trying to install a master on a Proxmox VM it will not start.
My Setup:
- Host: Proxmox 7.0.7 (I tried with 6.4.4 as well)
- Guest: Ubuntu 20.04.2
- K3S: v1.21.3+k3s1 (I tried with v1.19.13+k3s1 as well)
- MariaDB: 10.3
I'm running these commands in order to install the master
export K3S_DATASTORE_ENDPOINT='mysql://DB_USER:DB_PASSWORD@tcp(DB_IP:DB_PORT)/DB_SCHEME'
curl -sfL https://get.k3s.io | sh -s - server --node-taint CriticalAddonsOnly=true:NoExecute --tls-san NGINX_LOADBALANCER_IP
This is the output of installation and startup:

From there the restarts continue.
As mentioned I've tried with multiple versions, but nothing seems to work. Also I am not really getting an error.
The only hint I've found in different GitHub issues was to enable containerization regarding Raspberry PI by editing /boot/cmdline.txt.
However I am not getting the issue on a PI but rather on a Proxmox-VM.
Is there something I am missing?
Somehow this guy managed to get it to run in the same setup.
Did someone else make it run and might provide some reference?
