Deploy on Railway

Deploy Apache Answer on Railway to self-host a full-featured Q&A platform for your team or community. Apache Answer is an open-source alternative to Stack Overflow for Teams, built under the Apache Software Foundation, giving you complete control over your knowledge base with zero licensing fees.

This Railway template pre-configures Apache Answer with a PostgreSQL database, persistent storage for uploads and configuration, and automated first-run setup via environment variables. Run Apache Answer on Railway and have a production-ready Q&A community live in minutes.

Getting Started with Apache Answer on Railway

After deploying, visit your Railway-generated public URL. The template uses AUTO_INSTALL=true to skip the manual install wizard — your Q&A platform is ready immediately. Log in with the admin credentials set in your environment variables (ADMIN_NAME and ADMIN_PASSWORD). Navigate to the Admin panel via the user menu to configure site settings, manage users, add tags, and customize your community. Post your first question to verify everything works. Invite team members by sharing the URL or enabling OAuth login through the plugin system.

Self-Hosting Apache Answer with Docker

Run Apache Answer locally with Docker Compose and PostgreSQL:

version: "3"
services:
  answer:
    image: apache/answer:latest
    ports:
      - "9080:80"
    volumes:
      - answer-data:/data
    environment:
      - AUTO_INSTALL=true
      - DB_TYPE=postgres
      - DB_HOST=postgres:5432
      - DB_USERNAME=answer
      - DB_PASSWORD=changeme
      - DB_NAME=answer
      - SITE_NAME=My Q&A
      - SITE_URL=http://localhost:9080
      - ADMIN_NAME=admin
      - ADMIN_PASSWORD=securepassword123
      - [email protected]
      - [email protected]
      - LANGUAGE=en-US
      - EXTERNAL_CONTENT_DISPLAY=always_display
    depends_on:
      - postgres
  postgres:
    image: postgres:16
    volumes:
      - pgdata:/var/lib/postgresql/data
    environment:
      - POSTGRES_USER=answer
      - POSTGRES_PASSWORD=changeme
      - POSTGRES_DB=answer
volumes:
  answer-data:
  pgdata:

Or run with a single Docker command using SQLite:

FAQ

What is Apache Answer and why self-host it? Apache Answer is an open-source Q&A platform built by the Apache Software Foundation. Self-hosting gives you full control over your data, no vendor lock-in, unlimited users, and the ability to customize the platform with plugins and themes.

What does this Railway template deploy for Apache Answer? This template deploys two services: the Apache Answer application (apache/answer:latest) and a Railway-managed PostgreSQL database. It includes a persistent volume for uploads and configuration, automated first-run setup, and a public HTTPS domain.

Why does Apache Answer on Railway need PostgreSQL instead of SQLite? While Apache Answer supports SQLite for development, PostgreSQL provides concurrent write support, better performance at scale, point-in-time recovery, and production-grade reliability. Railway's managed Postgres includes automatic backups and monitoring.

How do I enable OAuth login in self-hosted Apache Answer? Apache Answer supports OAuth via its plugin system. After deploying, go to Admin → Plugins and enable the Google or GitHub connector plugin. Configure the OAuth client ID and secret in the plugin settings. Plugin images with OAuth pre-installed are available at apache/answer:latest-plugins.

How do I back up my self-hosted Apache Answer data on Railway? Your Q&A data lives in the PostgreSQL database — use Railway's database backup features or connect via the public URL to run pg_dump. Uploaded files are stored on the persistent volume at /data/uploads. For automated backups, consider adding an S3 storage plugin.
