Unfortunately, **K3s does *not* support Raspberry Pi Zero** because the Zero is based on **ARMv6**, while K3s requires **ARMv7** or newer. This is confirmed in the [K3s GitHub issue on ARM support](https://github.com/k3s-io/k3s/issues/2699).

✅ **Solution**: Use at least a **Raspberry Pi 2, 3, 4, or Zero 2W**, which are ARMv7/ARMv8 compatible. I run stable multi-node Pi 4 clusters using K3s, and they work flawlessly.

#### Example setup for Pi 4:

```bash

# On the master:

curl -sfL https://get.k3s.io | sh -

# On each worker:

curl -sfL https://get.k3s.io | \

K3S_URL="https://<MASTER_IP>:6443" \

K3S_TOKEN="<TOKEN>" sh -
