OutlineWiki MinIO S3 Presigned Attachment & 1.25x Storage Guide
Hostinger KVM NVMe
OutlineWiki 8GB pick (90,000 IOPS) — KVM 4 (4 vCPU / 16GB DDR5 / 200GB NVMe)
InterServer Price-Lock KVM & ZFS
Low-RTT node for outline Node.js + Hocu (19 ms CRDT sync)
UltaHost Dedicated EPYC VDS
Steady OutlineWiki secondary tier (25–100 collaborative editors)
Presigned S3 PUT requests keep large PDFs and videos out of Outline Node RAM.
Storing wiki screenshots and architecture PDFs on local container volumes breaks horizontal portability and bloats Node.js buffers.
On OutlineWiki, we allocate 512 MB RAM to MinIO and size attachment volumes using s3_disk_gb = docs_media_gb * 1.25 to absorb object versioning and multipart upload staging.
OutlineWiki Reference Configuration for MinIO S3 Presigned Uploads & 1.25x Disk

AWS_SECRET_ACCESS_KEY=replace-with-strong-secret

AWS_S3_ACL=privateOutlineWiki Implementation Checklist: MinIO S3 Presigned Uploads & 1.25x Disk
Phase 1: MinIO S3 Presigned Uploads & 1.25x Disk
Configure MinIO bucket CORS to allow PUT and GET requests from https://wiki.example.internal only.
Phase 2: MinIO S3 Presigned Uploads & 1.25x Disk
Keep AWS_S3_ACL=private so OutlineWiki serves expiring signed download links instead of public bucket URLs.
Phase 3: MinIO S3 Presigned Uploads & 1.25x Disk
Provision at least 1.25x your projected media GB (for example, 80 GB raw docs -> 100 GB S3 disk pool).
Phase 4: MinIO S3 Presigned Uploads & 1.25x Disk
Enable MinIO server metrics endpoint to alert at 80% disk utilization before presigned uploads fail.
OutlineWiki Infrastructure Recommendation for MinIO S3 Presigned Uploads & 1.25x Disk
Always proxy MinIO on a separate subdomain (s3.domain) with HTTP/2 TLS.
In our audit on OutlineWiki, teams with <= 80 GB media run cleanly on the 100 GB NVMe inside Hostinger KVM 2 ($11.99/mo promo), while media-heavy engineering orgs offload S3 storage cleanly at $6.00/mo.
OutlineWiki Hardware Ledger: NVMe Throughput vs Base Price
Packet-to-Disk Path for outline Node.js + Hocuspocus Yjs CRDT + OIDC on OutlineWiki
[+] Key Infrastructure Pros
- Keeps outline.env buffers stable at 100 collaborative editors via 8GB compute.
- Protects 19 ms CRDT sync objectives under heavy Postgres tsvector document graph + MinIO assets writes (90,000 IOPS).
- Trims OutlineWiki 3-year infrastructure bills 70%–85% versus metered SaaS seats.
[-] Operational Constraints
- Unlocking $10.49/mo on Hostinger KVM NVMe depends on annual commitment rather than 1m billing.
- Base OS templates need outline.env tuning (WEB_CONCURRENCY=4 & COLLABORATION_MAX_CLIENTS=150) before peak load.
Deploy This OutlineWiki Stack If
- DevOps squads standardizing outline Node.js + Hocuspocus Yjs CRDT + OIDC (100 collaborative editors) on KVM nodes.
- Builders needing root access to set WEB_CONCURRENCY=4 & COLLABORATION_MAX_CLIENTS=150 in outline.env.
When To Choose Alternatives
- Two-day load tests where InterServer Price-Lock KVM & ZFS pay-per-hour beats annual commitments.
- Mandates requiring vendor-staffed 24/7 NOC contracts with zero SSH access.
