Applications¶

The homelab runs an automated media management stack commonly referred to as the *arr stack. All applications are deployed into the arr namespace on Kubernetes via ArgoCD, using the bjw-s app-template Helm chart (v4.6.2). Routing is provided by Cilium Gateway API with TLS certificates issued by cert-manager (homelab-ca-issuer).

Shared Configuration¶

All *arr applications receive common environment variables from the arr-env ConfigMap:

Variable	Value
`TZ`	`America/Chicago`
`PUID`	`977`
`PGID`	`988`

Most applications share the arr-data PersistentVolumeClaim for media and download storage, ensuring a unified /data directory structure across the stack.

Data Flow¶

The diagram below shows how data moves through the stack, from media requests through downloading and processing to playback.

ArgoCD Sync Waves¶

All arr applications deploy at sync wave 1. Homepage and Uptime Kuma deploy at sync wave 2* so that service endpoints are available before they attempt to query them.
