Overleaf Full (Self-Hosted)

This project provides a complete Docker-based setup to run Overleaf (ShareLaTeX) locally with full LaTeX support (scheme-full), using MongoDB (replica set) and Redis.

🧠 Context

This setup was originally created to run inside an Umbrel environment (via Portainer), but it works in any standard Docker environment.

The goal was to have:

• Full LaTeX support (no missing packages)
• Local, self-hosted Overleaf instance
• Simple and reproducible deployment

---

⚙️ Requirements

• Docker
• Docker Compose

---

🚀 How to run

1. Clone the repository

git clone https://github.com/oroderico/overleaf-full.git
cd overleaf-full

---

2. Build and start the containers

docker compose up -d --build

This will:

• Build the custom Overleaf image (with full TeX Live)
• Start MongoDB (with replica set)
• Start Redis
• Start Overleaf

---

3. Access Overleaf

Open your browser:

http://umbrel.local:8085

---

🐳 Services

• overleaf → Main application
• mongo → Database (replica set enabled)
• redis → Cache/session store

---

📦 Volumes

Persistent data is stored in:

• mongo_data
• overleaf_data

---

🏗️ Image Details

The Overleaf image is built from:

FROM sharelatex/sharelatex:latest

RUN tlmgr option repository https://ftp.math.utah.edu/pub/tex/historic/systems/texlive/2025/tlnet-final && \
    tlmgr update --self && \
    tlmgr install scheme-full && \
    tlmgr path add

This installs the full TeX Live distribution to avoid missing LaTeX packages.

---

⚠️ Notes

• The image is large due to scheme-full
• First build may take several minutes
• MongoDB is configured with a single-node replica set (required by Overleaf)

---

🔐 Security

This setup is intended for local or controlled environments.

Before exposing to the internet:

• Add authentication layer
• Use HTTPS (reverse proxy)
• Restrict access

---

📌 Why not use Overleaf SaaS?

• Full control over data
• Offline capability
• No external dependency
• Custom LaTeX environment
