Overview

Mylar3 is the automated comic book downloader and manager for the homelab. It monitors comic series, searches for new issues via Usenet indexers (through NZBGet), and organises downloaded CBZ/CBR files into the comics library on UnRAID.

Access

Type URL Notes
Internal https://mylar.home.local LAN access via Step-CA TLS

No external route — internal management only.

Volumes / Bind Mounts

Host Path Container Path Purpose
/home/jeeves/docker/arr/mylar/config /config Mylar3 database and settings
/media/jeeves/1TB_Vol2/downloads/usenet/complete/books /downloads Completed downloads (Ceph OSD, shared with books)
/mnt/Multimedia/Books/Comics /comics Comics library (NFS from UnRAID)

Integration Points

Service Connection Method Purpose
NZBGet API (http://nzbget:6789) via media-network Download client

Mylar3 connects directly to NZBGet rather than through Prowlarr. Indexers are configured directly in Mylar3 settings.

Notes / Gotchas

  • Mylar3 uses ComicVine as its metadata source — a free API key from comicvine.gamespot.com is required and stored in the Mylar3 config.
  • The /downloads path is shared with LazyLibrarian (both point to the books completion directory). Ensure Mylar3's category in NZBGet is distinct to avoid processing conflicts.
  • Mylar3's database (mylar.db) stores the full comic watchlist and download history. Back it up before upgrades.
