Deploy and Host Kiwix Knowledge Library on Railway

Read a persistent ZIM knowledge archive through a private web server.

Draft status: Configuration and upstream documentation reviewed. Container startup, Railway application workflows, restart behavior, backup restoration and costs remain unverified.

About Hosting

Read a persistent ZIM knowledge archive through a private web server.

Service	Role	Persistent path
`core`	Private application or dependency	`/data`
`kiwix`	Public owner gateway	`None`

Why Deploy

Run this application in your own Railway project, with explicit configuration and storage under your control.

Common Use Cases

Read an archived reference collection through the browser.
Host a curated ZIM knowledge library.

Dependencies for Kiwix Knowledge Library

Deployment Dependencies

The application images are pinned by registry digest. Database services, when included, stay on the private network. One replica is supported for each volume-backed service.

First use

Open the kiwix service's HTTPS domain. Sign in to the owner gateway with username admin and its generated ACCESS_PASSWORD. Complete the application's own setup afterward.

API calls must also send X-Template-Key with that owner password. The gateway forwards native Bearer tokens, strips Basic Authorization, and limits requests to 32 MiB. Browser sessions receive a secure owner cookie. Native clients, webhooks and public sharing require specific compatibility checks before use. Gateway /healthz only checks the proxy, not application readiness.

Allow the first run to download the selected ZIM archive. The default is the English mathematics mini collection. Open the library, search and view an article. The downloaded file is reused on restart.

Scope and limitations

Unpublished draft; container startup, application workflows and recovery are not runtime-verified.
Default first start downloads the approximately56MB mathematics mini archive. Choose another trusted ZIM_URL before first deployment.
Changing ZIM_URL does not overwrite existing library.zim; replace the persistent archive deliberately.

Acceptance checks before use

Confirm the public endpoint rejects unauthenticated requests.
Wait for initial download, open an article and search; confirm restart reuses the same file.
Back up all persistent storage; restart and restore a copy before production use.
Confirm generated credentials are distinct on a second fresh deployment.
Back up every listed persistent path and database, then restore into a separate test project.
Measure Railway usage with representative data and workload before estimating operating costs.

Backups and upgrades

Back up databases, file volumes, encryption keys and configuration together. Keep a copy outside the running project. Review upstream migration notes before changing a digest; rollback can require restoring a compatible database and files, not just selecting an older image.

Upstream project

Product and alias searches found no matching public Railway listing during this research. This is a bounded search result; private, unindexed or differently named listings may exist. It is not evidence of demand or revenue.

Upstream software retains its own license and edition restrictions. This deployment draft does not imply upstream endorsement.
