Dustin b8ccbd0b09 jenkins: Avoid SELinux relabel of data dir 
Setting a static SELinux level for the container allows CRI-O to skip
relabeling all the files in the persistent volume each time the
container starts.  For this to work, the pod needs a special annotation,
and CRI-O itself has to be configured to respect it:

```toml
[crio.runtime.runtimes.runc]
allowed_annotations = ["io.kubernetes.cri-o.TrySkipVolumeSELinuxLabel"]
```

This *dramatically* improves the start time of the Jenkins container.
Instead of taking 5+ minutes, it now starts instantly.

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.
