Deploy and Host Docmost on Railway

Docmost is an open-source collaborative wiki and documentation platform — a self-hosted alternative to Notion and Confluence. It provides real-time collaborative editing, a rich-text editor with diagram support (Draw.io, Excalidraw, Mermaid), spaces and groups with granular permissions, and full-text search across your entire knowledge base.

About Hosting Docmost

Hosting Docmost means running the official docmost/docmost container alongside two stateful services: PostgreSQL, which stores all workspaces, pages, and users (schema migrations run automatically at boot), and Redis, which powers queues and real-time collaboration. The app listens on port 3000 and needs APP_URL (its public URL), a 32+ character APP_SECRET, DATABASE_URL, and REDIS_URL. Uploads and attachments live on disk at /app/data/storage, so a persistent volume is mounted there to survive redeploys. This template provisions all of it: Railway's official Postgres and Redis templates, connection strings injected via service references, a generated secret, and a public domain — no manual wiring required.

Common Use Cases

• Internal team wiki and knowledge base with real-time collaborative editing
• Project and product documentation hub organized into spaces with permissions
• Self-hosted Notion/Confluence alternative for teams requiring full data ownership

Dependencies for Docmost Hosting

• PostgreSQL (deployed from Railway's official template; provides DATABASE_URL)
• Redis (deployed from Railway's official template; provides REDIS_URL)

Deployment Dependencies

• Docmost documentation: https://docmost.com/docs
• Self-hosting / installation guide: https://docmost.com/docs/installation
• Source code: https://github.com/docmost/docmost
• Docker image: https://hub.docker.com/r/docmost/docmost

Implementation Details

The template deploys three services: Docmost (image docmost/docmost:0.95.0, pinned immutable tag), Postgres, and Redis. Docmost connects over Railway's private network via DATABASE_URL=${{Postgres.DATABASE_URL}}?sslmode=disable and REDIS_URL=${{Redis.REDIS_URL}}. APP_SECRET is generated per deployment with ${{secret(64, "abcdef0123456789")}}, and APP_URL references the service's own generated public domain. A persistent volume mounted at /app/data/storage retains uploaded files across redeploys.
