By default, the `instance` label for discovered metrics targets is set to the scrape address. For Kubernetes pods, that is the IP address and port of the pod, which naturally changes every time the pod is recreated or moved. This will cause a high churn rate for Longhorn manager pods. To avoid this, we set the `instance` label to the name of the node the pod is running on, which will not change because the Longhorn manager pods are managed by a DaemonSet. |

Dustin's Kubernetes Cluster
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).
See Cluster Setup for details.
Jenkins Agents
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.
See Jenkins Kubernetes Integration for details.
Persistent Storage
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.
See Persistent Storage Using Longorn for details.
