On Raspberry Pi you need to take additonal steps:
|
||||
|
||||
* Manually enable cgroups by appending
|
||||
`cgroup_memory=1 cgroup_enable=memory` to `/boot/cmdline.txt`,
|
||||
* Disable swap with `swapoff -a; apt-get purge -y dphys-swapfile`
|
||||
* For mounting Longhorn volumes on Rasbian install `open-iscsi`
|
||||
|
||||
For `arm64` nodes add suitable taint to prevent scheduling non-multiarch images on them:
|
||||
|
||||
```bash
|
||||
kubectl taint nodes worker9.kube.k-space.ee arch=arm64:NoSchedule
|
||||
```
|
||||
|
||||
For door controllers:
|
||||
|
||||
```
|
||||
for j in ground front back; do
|
||||
kubectl taint nodes door-${j}.kube.k-space.ee dedicated=door:NoSchedule
|
||||
kubectl label nodes door-${j}.kube.k-space.ee dedicated=door
|
||||
kubectl taint nodes door-${j}.kube.k-space.ee arch=arm64:NoSchedule
|
||||
done
|
||||
```
|
||||
|
||||
To reduce wear on storage:
|
||||
|
||||
```
|
||||
echo StandardOutput=null >> /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
|
||||
systemctl daemon-reload
|
||||
systemctl restart kubelet
|
||||
```
