Dustin 5869afa923 jenkins: Add PVC for airplaypi Buildroot job 
Buildroot jobs really benefit from having a persistent workspace volume
instead of an ephemeral one.  This way, only the packages, etc. that
have changed since the last build need to be built, instead of the whole
toolchain and operating system.

Jenkins in Kubernetes

Kubernetes Setup

Configure Jenkins resources:

ln imagepull-gitea jenkins/.dockerconfigjson
kubectl apply -k jenkins

Jenkins Setup

Install Kubernetes plugin.

Set TCP port for inbound agents setting (Manage Jenkins → Configure Global Security) to Fixed and enter 40414.

Configure Kubernetes (Manage Jenkins → Manage Nodes and Clouds → Configure Clouds:

  1. Add a new cloud → Kubernetes
  2. Enter a name
  3. Kubernetes Cloud details...
    • Kubernetes URL: (leave blank; will use Kubernetes service discovery)
    • Kubernetes Namespace: jenkins-jobs
    • Credentials: - none - (will use Service Account token)
    • Jenkins tunnel: jenkins.jenkins.svc.cluster.local: (trailing colon!)

iSCSI Persistent Volume

Because of the large size of the Jenkins volume, it does not work well managed by Longhorn. Instead, we use a pre-provisioned iSCSI volume on the Synology NAS. This improves performance and avoids keeping multiple replicas of the Jenkins data, while still benefiting from snapshots, etc.
