\* Configuration panel only available internally<br>
** Current implementation only support SQLite, making manual backups a necessity<br>
<sup>1</sup> Missing automated configuration pipeline for environment variable injection<br>
<sup>2</sup> Missing configuration for NAS volume mounting (over network)<br>
<sup>3</sup> Missing Longhorn scheduling for saving media_store and secret management<br>
<sup>4</sup> Currently migrating from Gitlab installation<br>
<sup>4</sup> Configuration completed, awaiting data migration from Gitlab<br>
<sup>5</sup> Missing dashboard configuration<br>
<sup>6</sup> Done through volume backup, because not possible otherwise<br>
<sup>7</sup> Done, but needs a reimplementation using kustomize for secret separation from configmap<br>
<sup>8</sup> Done but included in a grouped project `Monitoring`<br>
<sup>9</sup> Handled by Longhorn<br>
