[ARA Records Ansible][0] is a results storage system for Ansible. It provides a convenient UI for tracking Ansible playbooks and tasks. The data are populated by an Ansible callback plugin. ARA is a fairly simple Python+Django application. It needs a database to store Ansible results, so we've connected it to the main PostgreSQL database and configured it to connect and authenticate using mTLS. Rather than mess with managing and distributing a static password for ARA clients, I've configured Autheliad to allow anonymous access to post data to the ARA API from within the private network or the Kubernetes cluster. Access to the web UI does require authentication. [0]: https://ara.recordsansible.org/
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.
