PostmarketOS-Powered Kubernetes Cluster
Having a few Raspberry Pi 4s at my disposal, I found myself somewhat dissatisfied with their processing capabilities and power management features. This led me to explore alternative solutions, particularly given the collection of old smartphones gathering dust in my drawer.
Being a Linux distribution based on Alpine, you can really use your smartphone as if it’s a computer (or in my case, a server): this means that you can install for example sway, KDE or literally any other desktop environment / user interfaces you want and run your favorite applications. Don’t spend half a day debugging iptables: postmarketOS comes with nftables and the default rules in/etc/nftables.nft are the reason why your Kubernetes network might get messed up Trying again After recompiling the kernel, copying and installing resulting.apk file ( scp linux-postmarketos-qcom-msm8998-6.0-r2.apk root@dumpling and apk add -u linux-postmarketos-qcom-msm8998-6.0-r2.apk) and rebooting, I was able to start k3s and see the node joining the cluster.
