Want a self‑hosted docs hub? Hostinger’s guide shows how to spin up Docmost with Docker Compose in minutes.

Key take‑away: a single `docker-compose.yml` (plus a few env vars) pulls the images, builds the DB and web services, and you’re ready to store, search and share files without third‑party lock‑in.

@electret great, it get's never boring in the #HomeLab right :) I used to have a simple list with things I plan to do in #docmost but nowadays started to use Issues in #forgejo. So #forgejo is now really the single source of truth in the homelab with all the glory #git delivers.

Immer wieder spannend, welche Softwareprojekte man noch nicht kennt, teils weil neu, teils, weil es an einem bislang vorbei ging.

#Docmost kannte ich noch nicht. Wenn ich das richtig sehe, ist das ähnlich wie #Dokuwiki u.a. #Wiki eine reine #Webanwendung. Das ist super, wenn mehrere Leute auf die Inhalte zugreifen müssen. Für rein persönliche Dokumentationen ist mir eine lokale Lösung (ggf. mit Synchronisationsmöglichkeit zwischen verschiedenen Geräten) lieber. Die funktioniert auch, wenn ich offline bin oder der Server crasht.

Ich dokumentiere (für mich) inzwischen alles mit #Joplin. Sicher gibt es dafür bessere / geeignetere Lösungen wie eben Wikis, aber bei mir geht es hauptsächlich z.B. darum, z.B. die Installation, Anpassungen, Änderungen und Updates an einem Systems wie einem Server für mich selbst zu dokumentieren. Das mache ich in einer einzelnen Joplin Notiz.

@blog @kaschmir Ich muss zugeben, dass ich nicht genau weiß, was Confluence alles kann. Ich nutze Docmost echt viel inzwischen. Es beschreibt sich eher so: "Wiki, aber in schön und Multiuser-fähig". #Docmost #Joplin #NextCloud #did

Looking for FOSS alternatives to Notion, preferably with much of the same functionality and preferably with the option to self-host and optionally integrate with Git. I know y'all can help me out with this! Docmost looks promising but they have pricing, which makes me wary.

@arkhost I got to have a look at it. I still search for an app for quick notes, before writing down stuff in my #docmost instance.

Thanks for the hint. 🙂

@net_gremlin Na um so besser, dass ich mein #microsoft365 Abo an den Nagel gehängt, und mir ne schöne #opensource Lösung gebaut habe:

#paperlessngx
#docmost
#nextcloud

Und #infomaniak für Mails

Para los que tengáis #docmost en en vuestro homelab, no os recomiendo por el momento, actualizar a la nueva versión 0.24.0 ya que hay gente, entre la que me incluyo, que tras instalarlo no arranca.

El error que muestra es el siguiente:

docmost-1 | /app/apps/server:
docmost-1 |  ERR_PNPM_RECURSIVE_RUN_FIRST_FAIL  [email protected] start​:prod:​ cross-env NODE_ENV=production node dist/main
docmost-1 | Exit status 1

Si lo habéis actualizado y os muestra ese error, lo más rápido es volver a cargar la imagen de la versión 0.23.2 en vuestro docker:

image: docmost/docmost:0.23.2

Reiniciar y listo👍

Dejo aquí el issue abierto en su repositorio Github:

Docmost: Open-source collaborative wiki and documentation software

https://docmost.com

Das klingt ernsthaft gut und würde einige Usability-Probleme des Mediawikis lösen. Unter anderem durch Markdown als Standard und Drag & Drop-Seitenhierarchie.

Realtime-Collaborative-Editing, schicke Kommentare und draw.io-Integration sind auch nicht zu verachten.

Scheint mir noch netter (ausgewogener) als Bookstack oder xWiki. Fehlt nur eine Import-/Migrationsfunktion.

Took a bit of comparing features, but for my Notion alternative, I went with Docmost. :)

* update: decided to remove this one, as I lean more on using plain text files. Especially that I have started exploring using LLMs: https://social.ayco.io/@ayo/115090396384901152

Docmost je docela zajímavý projekt. Už ho mám dva týdny a datluji v něm domáci KB. A hodně mi to připomíná confluence. Jen tohle je Open Source. V dockeru ho jde provozovat i na Synology NAS. #docmost #selfhosted

На Регулярных Выражениях @oreolek рассказал про #Docmost, альтернативу Notion с открытым исходным кодом. Может в режиме реального времени ловить изменения, так что отлично подойдёт как вики для моих знакомых.

I'm very curious about what my Synology was doing here. In an effort to self-host all the things, I'm testing different Wiki containers, especially since I like to write stuff in markdown.

While deploying a Docker service for docmost, which comes with a couple other containers, my CPU usage apparently went negative?

Explain yourself, Synology DSM / Container Manager, since I got nothing.

/shrug

#homelab #synology #selfhosted #docmost #docker #containers

@magnus919 Borja @bookstack and #docmost are good choices, in our case we use #outline if you want the docker-compose you can have a look at https://outline.enlace.app/s/ccc29cc4-0810-4ac0-831a-f61a775df0e0

Are there any public red flags for #Docmost?
Had a quick scan of #MediaWiki alternatives (like SiYuan, Trilium) for self-hosted knowledge-base and stuff.
And this looks to be pretty polished - even as a beta.
And supports a proper multi-user mode, which the above alternatives don't.
