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.
