# Deploy and Host S3 Bucket Viewer (Secure) - s3manager - S3 Browser on Railway

S3 Bucket Viewer (Secure) is a lightweight web UI for browsing an S3-compatible bucket on Railway. It deploys **s3manager** as the file explorer and places **caddy-zero-trust** in front as an authentication gateway, so the viewer can be exposed safely while the S3 browser stays on Railway’s private network.

## About Hosting S3 Bucket Viewer (Secure) - s3manager - S3 Browser

This template deploys two services: **s3manager** (the S3 web UI) and **caddy-zero-trust** (a Basic Auth reverse proxy). Configure your Railway Bucket credentials (ENDPOINT, REGION, ACCESS_KEY_ID, SECRET_ACCESS_KEY) and s3manager will connect to your S3-compatible storage. Then caddy-zero-trust publishes a single public URL and forwards authenticated traffic to s3manager over Railway Private Networking. Keep s3manager private (no public domain) so only the proxy is reachable from the internet.

## Common Use Cases

- Inspect and manage objects in a Railway Bucket (upload, download, delete).
- Quickly validate that your app is writing files to S3-compatible storage.
- Provide temporary, password-protected access for admins/support.

## Dependencies for S3 Bucket Viewer (Secure) - s3manager - S3 Browser Hosting

- A Railway project with a **Railway Storage Bucket** (S3-compatible credentials).
- One public domain for the proxy (Railway-generated domain or a custom domain).

### Deployment Dependencies

- s3manager (Web UI): https://github.com/cloudlena/s3manager  
- Railway Storage Buckets docs: https://docs.railway.com/guides/storage-buckets  
- caddy-zero-trust template: https://railway.com/deploy/caddy-zero-trust  

### Implementation Details

**Recommended routing**
- Do **not** generate a public domain for `s3manager`.
- Only `caddy-zero-trust` should have a public domain.
- Set `caddy-zero-trust.UPSTREAM_URL` to the private URL of s3manager (e.g., `http://:`).
