jellyfin-pdb-mgr-rs

jellyfin-db-pgr watches a Jellyfin server for actively playing items and updates a Kubernetes PodDisruptionBudget to prevent server shutdowns.

How?

Deploy jellyfin-pdb-mgr to your cluster (only one replica is needed) and set the following environment variables:

POD_NAMESPACE - the namespace the pod runs in. You should use valueFrom.fieldRef.fieldPath: metadata.namespace for this.
RUST_LOG (optional) - the log level (i.e. info, debug,, warn, error)
UPDATE_INTERVAL - how often in seconds to check for players and to patch the PDB. The default value is 10.
PDB_NAME - the name of the PBB object in the same namespace as the pod to update. You need to create this PDB yourself.
JELLYFIN_URL - the URL to your Jellyfin instance.
JELLYFIN_API_KEY - the Jellyfin API key to use.
MIN_STREAMS - the minimum number of now playing items to consider when updating the PDB. Default is 1.
