There's obviously a bug or something in `mqttmarionette` because it occasionally gets "stuck" in a state where it is running but does not reconnect to the MQTT broker. In such situations, it has to be restarted (and even then it doesn't shut down correctly but has to be killed with SIGKILL, usually). I have been doing this manually, but with this shell script and a corresponding "shell command" integration in Home Assistant, it can be done automatically. This is similar to how Home Assistant restarts Mopidy on the living room stereo when it gets into the same kind of state.
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.
