Obsidian Sync Server

A headless Docker container that uses obsidian-headless to keep a local vault directory synchronized with Obsidian Sync.

Architecture

• Base Image: Node.js 20 Slim
• Sync Engine: obsidian-headless (Official CLI)
• Mode: Continuous Sync (Watches for changes and pushes/pulls in real-time)

Quick Start

1. Clone the repo:

   git clone https://gitea-wc4w40kskg0c4g400s0wcgsg.coolify-7dou.ja7z.net/hermes/obsidian-sync-server.git
   cd obsidian-sync-server
   

2. Configure Environment:

   cp .env.example .env
   # Edit .env with your vault name, E2EE password, and device name
   nano .env
   

3. Launch:

   docker-compose up -d
   

4. First-Time Login: The obsidian-headless tool requires an initial login to your Obsidian account.

   docker exec -it obsidian-sync-server ob login
   

   Follow the on-screen instructions to authenticate. Once logged in, the container will automatically proceed to sync-setup and sync --continuous.

Interaction

Since this is a headless server, you interact with your vault by:

• Filesystem: Accessing the ./vault folder on your host machine.
• Local Obsidian: Opening the ./vault folder in your local Obsidian app.
• CLI: Running commands via docker exec obsidian-sync-server ob <command>.
