Deploy and Host VaultS3 on Railway

VaultS3 is a lightweight, S3-compatible object storage server with a built-in web dashboard. It ships as a single binary with low memory usage and AES-256-GCM encryption at rest. Since it speaks the S3 API, existing tools like the AWS CLI or boto3 connect to it without changes.

About Hosting VaultS3

VaultS3 runs as a single container exposing one port (9000) that serves the S3 API, the web dashboard, metrics, and health endpoints. Hosting requires a persistent volume mounted at /data for object data and BoltDB metadata, plus two environment variables that set the admin credentials. Optional variables enable scheduled full or incremental backups to a local directory. Because it is S3-compatible, migration means pointing your existing S3 client at the Railway app URL.

Common Use Cases

S3-compatible object storage for applications (drop-in for AWS S3 or MinIO)
Self-hosted storage with a web dashboard and fine-grained IAM users, groups, and policies
Private backup target with scheduled backups and encryption at rest

Dependencies for VaultS3 Hosting

Persistent volume mounted at /data (object data + metadata)
VAULTS3_ACCESS_KEY and VAULTS3_SECRET_KEY (admin credentials)

Implementation Details

Set VAULTS3_ACCESS_KEY and VAULTS3_SECRET_KEY. Optional VAULTS3_BACKUP_* variables enable scheduled backups (cron, retention, incremental).
