Oh I have quite a few that I've set up then pulled out of service for various reasons. I'm always evaluating potential use-cases for new services and if a different service would better suit my needs than what I have deployed currently. It's definitely a hobby.

Some container-based projects that I'm loosely tracking updates for and have deployed, but since, have pulled out of service (non-exhaustive):

Media:

• Calibre / Calibre-Web

  • Supplanted by Audiobookshelf. For tagging and book conversion I just temporarily install Calibre on my Workstation when the need arises.

• FreshRSS

  • Did not end up using it for much at the time. Re-evaluating if I'd like to stand it up again.

• Plex

  • Plex is nice but too many drawbacks that don't work for me. Supplanted with Jellyfin.

• Overseerr

  • Didn't have much use for this, but it will likely change soon. Since I've stuck with Jellyfin I'll be going with Jellyseer if I decide to stand up this kind of service again.

• Libreddit

  • Rarely made use of it. Nice project, but it's not feasible now for obvious reasons.

• Miniflux

  • Same as FreshRSS, though I'm a big fan of go and rust projects in general so this is the one I'm more keen on re-implementing.

• Tautulli

  • Part of the Plex ecosystem which I abandoned. It was useful software, but unfortunately locked to Plex.

• Unmanic

  • Never really had a use for this, though I thought I would at the time.

• TT-RSS

  • Project is decent but the author is a asshole and very user-hostile, so I dropped it when I retooled my homelab a few years ago.

• Jackett

  • Supplanted with Prowlarr.

• Ombi

  • Same as the reason for dropping Overseerr.

• Neko

  • Did it's job, consumed lots of resources, and no arm64 docker image; though I managed to build my own. Got rid of it when I no longer had a use for the service.

Archival/Documentation:

• Filestash

  • Something about the project rubbed me the wrong way, vague on the details though.

• Shiori

  • Was decent but the lack of updates then subsequent maintainer turnover scared me off. I check in from time to time to see how the project's going.

• Wallabag

  • Ended up being too slow and clunky for me, but that could be the hardware I was running it on at the time.

• Archivebox

  • Same as above, but it definitely wasn't the hardware.

• Bookstack

  • It was alright but decided I didn't need a separate service for documentation, I just use Code-Server with a documentation repo and raneto to give me a pretty page to navigate and for the family.

• Filerun

  • Worked well while I was using it, not a fan of the closed-source nature and just didn't feel the need to redeploy when I retooled my infrastructure.

• Wiki.js

  • Same as bookstack, didn't really have a use for a separate service.

Dashboards:

I'm going to preface this by saying I have some sort of addiction with dashboards, it's unhealthy really.

• Organizr

  • Didn't like how everything was an iframe and it seemed particularly resource heavy for what I needed it to do.

• Heimdall

  • My second dashboard. Liked the API integration not so much the design.

• Homer

  • Wasn't a fan of the design.

• Homarr

  • Also didn't like the design much.

• Flame

  • Decent project, but decided to move on to something configuration file based.

• Sui

  • Liked this one a lot and used for quite a while before homepage lured me away with API widgets.

Infrastructure:

• Apt-cacher-ng

  • Inadvertently made my infrastructure brittle with how I had it implemented. Decided to just rebuild my cluster's cloud image on-demand instead of daily and update my apt distros the old-fashioned way.

• LLDAP

  • Liked this project a lot, but added complexity to my infrastructure that could be more simply achieved other ways.

• OpenLDAP

  • Same as lldap, but more feature rich and thus even more complicated.

• Docker Registry

  • Set-up briefly but found a better use-case with Gitea's integrated package registry which I'd already had deployed.

• Guacamole

  • Used this for a while, but the clipboard situation sucked at the time and I gravitated to just using SSH anyway, and since I have Proxmox on hypervisor duties just used xterm.js or noVNC for console access.

• Watchtower

  • Did it's job but the :latest tag is dangerous to use. I like having change logs, an evaluation environment, and an approval based update workflow so I switched to renovate-bot.

• Netmaker

  • Was a decent option for sure and faster than what I'm using currently in theory, but seemed a little to unnecessarily complicated to keep running for me.

• Netboot.xyz

  • Definitely useful. Will probably redeploy it at some point.

• OpenSSH-Server

  • Supplanted with Wireguard implementation in Tailscale.

• Node-Red

  • Tried it very briefly but N8N fit my use-case better.
