<p>when using k3sup to setup k3s with raspbian buster on raspberrypi 4b it works (armv7 architecture; with reference below). with an exact similar similar setup procedure of agent nodes on pi zeros, and running raspi-config, it errors with the following failures:</p>
<pre><code>- CONFIG_CGROUP_CPUACCT: enabled
- CONFIG_CGROUP_DEVICE: enabled
- CONFIG_CGROUP_FREEZER: enabled
- CONFIG_CGROUP_SCHED: enabled
- CONFIG_CPUSETS: missing (fail)
- CONFIG_MEMCG: enabled
- CONFIG_KEYS: enabled
- CONFIG_VETH: enabled (as module)
</code></pre>
<p>a possible explanation may be that zeros are using armv6 architecture which have some reports mentioning that they may not be supported. There are also conflicting reports that it has been made possible to run on pi zeros.</p>

<p>Is there any configuration or that will enable k3s (agent) to successfully operate on raspberry pi zero (w)? If so what is the node os/version and k3s setup for this? Any help appreciated as this has been some uphill battle.</p>

<p>Unfortunately, k3s can't run on Pi Zero because Pi zero is based on ARMv6 and K3S only support ARM starting ARMv7. (see this Github issue : <a href="https://github.com/k3s-io/k3s/issues/2699" rel="nofollow noreferrer">https://github.com/k3s-io/k3s/issues/2699</a>).</p>
<p>If you want a Raspberry Pi to run K3s, use a Raspberry Pi with an ARMv7 CPU (Ex : Raspberry pi 4).</p>
