Deploy and Host SeaweedFS on Railway

Deploy SeaweedFS as a self-hosted S3-compatible object storage system on Railway with one click. SeaweedFS is a distributed file system optimized for storing and serving billions of files with O(1) disk seek — making it ideal for media storage, backups, and any application that speaks the S3 protocol.

This Railway template pre-configures SeaweedFS with master, volume server, filer, and S3 gateway running as a single service. It includes persistent volume storage, S3 authentication with access/secret keys, and a public endpoint ready for S3 client connections.

Getting Started with SeaweedFS on Railway

After deployment completes, your SeaweedFS S3 endpoint is live at the generated Railway domain. Configure any S3-compatible client (AWS CLI, s3cmd, boto3, rclone) using the S3_ACCESS_KEY and S3_SECRET_KEY from your Railway environment variables.

To create your first bucket and upload a file using AWS CLI:

aws configure set aws_access_key_id YOUR_ACCESS_KEY
aws configure set aws_secret_access_key YOUR_SECRET_KEY
aws --endpoint-url https://your-seaweedfs.up.railway.app s3 mb s3://my-bucket
aws --endpoint-url https://your-seaweedfs.up.railway.app s3 cp ./file.txt s3://my-bucket/

The filer UI is available on port 8888 internally for browsing stored files. The master dashboard runs on port 9333 for cluster status monitoring.

About Hosting SeaweedFS

SeaweedFS is an open-source (Apache 2.0) distributed file system inspired by Facebook's Haystack paper. It solves the "billions of small files" problem that traditional file systems and object stores handle poorly — each file requires only 40 bytes of metadata overhead and a single O(1) disk read to serve.

Key features:

Full Amazon S3 API compatibility (buckets, multipart uploads, versioning, lifecycle policies, object lock)
WebDAV support for mounting as a network drive
POSIX FUSE mount for local directory access
Cloud tiering to AWS S3, Google Cloud, Azure, and BackBlaze
Erasure coding (10.4) for cost-efficient warm storage
Filer metadata backed by LevelDB, MySQL, Postgres, Redis, or 10+ other stores
Cross-datacenter active-active async replication
Kubernetes CSI driver for persistent volumes

Why Deploy SeaweedFS on Railway

Self-host SeaweedFS on Railway for managed S3-compatible storage without AWS vendor lock-in:

One-click deploy with persistent volume and S3 auth pre-configured
No AWS bills — pay only for Railway infrastructure usage
Full S3 API means any existing S3 client or SDK works unchanged
Single container runs the entire stack (master + volume + filer + S3)
Scale storage by adjusting Railway volume size — no cluster management

Common Use Cases for Self-Hosted SeaweedFS

Application blob storage — Store user uploads, avatars, documents behind an S3 API that your app already knows how to use
Media serving at scale — Serve millions of images with O(1) disk reads, no hot-spotting on popular files
Backup destination — Use rclone, restic, or duplicati with SeaweedFS as an S3-compatible backup target
Development S3 mock — Replace AWS S3 in local/staging environments with a real S3-compatible endpoint

Self-Hosting SeaweedFS with Docker

Run SeaweedFS locally with S3 gateway enabled:

docker run -d \
  --name seaweedfs \
  -p 8333:8333 \
  -p 9333:9333 \
  -v seaweedfs_data:/data \
  chrislusf/seaweedfs:4.22 \
  server -s3 -dir=/data -ip.bind=0.0.0.0 -master.volumeSizeLimitMB=1024

For a multi-node production setup with docker-compose:

services:
  seaweedfs:
    image: chrislusf/seaweedfs:4.22
    ports:
      - "8333:8333"
      - "9333:9333"
      - "8888:8888"
    volumes:
      - seaweedfs_data:/data
    command: "server -s3 -dir=/data -ip.bind=0.0.0.0 -master.volumeSizeLimitMB=1024"

volumes:
  seaweedfs_data:

Configure S3 credentials after startup via weed shell:

docker exec seaweedfs weed shell &lt;
