Home Assistant has started sending the full sensor values for weather
metrics to Prometheus, even though their precision is way beyond their
accuracy. We don't need to see 4+ decimal points for these on the
Kitchen display, so let's round the values when we query.
This repository contains resources for deploying and managing my on-premises
Kubernetes cluster
Cluster Setup
The cluster primarily consists of libvirt/QEMU+KVM virtual machines. The
Control Plane nodes are VMs, as are the x86_64 worker nodes. Eventually, I
would like to add Raspberry Pi or Pine64 machines as aarch64 nodes.
All machines run Fedora, using only Fedora builds of the Kubernetes components
(kubeadm, kubectl, and kubeadm).
One of the main use cases for the Kubernetes cluster is to provide dynamic
agents for Jenkins. Using the Kubernetes Plugin, Jenkins will
automatically launch worker nodes as Kubernetes pods.
Persistent storage for pods is provided by Longhorn. Longhorn runs within
the cluster and provisions storage on worker nodes to make available to pods
over iSCSI.
