📝 Walkthrough

Walkthrough

The Helm chart version is bumped to 3.8.0. New values configure pod DNS behavior, host user namespaces, and priority classes, with corresponding conditional StatefulSet fields. The README documents these settings.

Changes

Helm pod configuration

Layer / File(s)	Summary
Pod settings and StatefulSet rendering charts/seerr-chart/values.yaml, charts/seerr-chart/templates/statefulset.yaml	Adds dnsPolicy, dnsConfig, hostUsers, and priorityClassName values and conditionally renders them in the pod specification.
Chart metadata and documentation charts/seerr-chart/Chart.yaml, charts/seerr-chart/README.md	Bumps the chart version to 3.8.0 and documents the new DNS and priority class settings.

Poem

I’m a rabbit with DNS in my hat,
Setting priorities, fancy like that.
Stateful pods hop into line,
With chart version 3.8.0 shining fine.
A tidy Helm update is here!

In `@charts/seerr-chart/README.md`:
- Line 104: Correct the Values table in the README: restore the service row’s
description to document service configuration, and add separate entries for the
hostUsers and priorityClassName pod settings using their corresponding defaults
and descriptions from the chart values.

In `@charts/seerr-chart/templates/statefulset.yaml`:
- Around line 34-36: Gate the hostUsers field in the StatefulSet template using
the Kubernetes version, rendering it only for clusters where spec.hostUsers is
supported (Kubernetes 1.25 or newer). Preserve the existing boolean check and
omit the field on supported 1.23/1.24 clusters; use the chart’s existing
version-gating conventions if available.
