Call GPT-6 Astra through DigitalOcean with the Responses API
Call GPT-6 Astra through DigitalOcean with the Responses API. Check access, create a key, send a request and compare costs before adding routing or agents.
Fix an OpenCode provider error with a read-only test
Diagnose OpenCode key, endpoint, model and permission failures with a disposable fixture, a read-only request and a denied edit.
Lock down a Droplet with Tailscale and private SSH
Lock down a Droplet with Tailscale, close public SSH, test access rules, and keep a recovery route. Follow the guide before adding private server applications.
Host a private Home Assistant server with Tailscale
Host a private Home Assistant server on a Droplet with Tailscale HTTPS, no public dashboard ports, backups, and clear limits for devices on your home LAN.
Run CI builds on disposable Droplets
Give one trusted GitHub Actions job a fresh Linux machine, keep its artifact, and confirm the Droplet disappears. Includes cleanup workflows and tests.
DigitalOcean Spaces private downloads with expiring links
Give each customer access to their own files. A Next.js companion checks ownership before issuing a short-lived download link, with tests for the requests that should fail.
Build your own OBS multistream server for Twitch and YouTube
Upload once from OBS and let a private relay send the stream to each platform. Includes Docker Compose, an encrypted connection, costs, and a rehearsal checklist.
Serve public files with a custom CDN domain
A working image URL is only the start. Test a new file, a stale copy, and a rollback before moving public assets to a CDN.
S3 vs Spaces for public file delivery and egress costs
Storage can look cheap until people start downloading. This comparison separates storage, requests, and delivery before a good launch becomes an expensive one.
Back Up a Docker Compose App and Test the Restore
A server snapshot can get a machine back. This guide keeps the application data, Compose files, and database dump you need to prove the app can return.
Deploy a Next.js App with Pull Request Previews
A preview URL does not replace review, but it gives a teammate a real deployed app to check before a change reaches production.
Run a Private, Always-On OpenClaw Assistant
An always-on assistant needs more than a server. Start with a fresh OpenClaw Droplet, protect the gateway, prove one private workflow, then grow from there.
Self-Host a Private Stoat Chat Server
A short, safe path for running Stoat on a new Ubuntu Droplet. It hardens SSH, installs the official stack, and stops for you to check each real boundary.
Debug a Failing CI Build with AI, Safely
Capture the useful error, create a minimal reproduction, then use a serverless model to narrow the problem before you change code.
Migrate n8n from SQLite to PostgreSQL on DigitalOcean
Changing one database setting is not a migration. Keep a verified recovery point, move the app data, and prove the new database before you retire the old one.
Monitor a Website with Uptime Kuma
A monitor on the same server as your app can disappear with the problem. Put Uptime Kuma elsewhere, then test the alert with a controlled failure.
Run a Private n8n Server and Test the Restore
A workflow server needs to survive a bad update or a lost Droplet. Keep its credentials, execution history, and configuration in an encrypted backup, then restore it somewhere safe.
Build an AI Pull Request Reviewer with GitHub Actions and DigitalOcean
A beginner-first walkthrough for a bounded AI pull request reviewer: it reads a redacted diff, posts one advisory comment, and leaves every merge decision to people.
Build an image upload and optimization pipeline
A browser uploads one original directly to private object storage. A small API starts a secured image function, and only optimized variants reach your CDN.
Set Up OpenCode with Serverless AI Inference
Install OpenCode, connect DigitalOcean Serverless Inference, verify a read-only request in a safe test project, then enable the provider in T3 Code.
Back Up a Minecraft Server to DigitalOcean Spaces
A small, boring backup job is what you want: pause world saves, archive the server data, upload it to a private bucket, then test the restore before a player needs it.
