How to Configure Docker Compose for Production on a VPS (2026): Healthchecks, Resource Limits, Logs, Secrets, and a Rollback Checklist

Just because Docker Compose can get your services running doesn't mean they're ready for production. The most common problems on a VPS are containers without healthchecks, misuse of restart policies, no CPU/memory limits, logs filling up the disk, secrets leaking through .env, no Volume backup before updates, and no rollback plan. This article explains how to harden Docker Compose for production, following the real order of going live.

Slow WordPress on a VPS? (2026): PHP-FPM, OPcache, Redis, Nginx Cache, and Slow Query Optimization

A slow WordPress site on a VPS doesn't necessarily mean the machine is too weak. Common bottlenecks are usually PHP-FPM process counts, OPcache not enabled, Redis Object Cache not wired up properly, missing Nginx/FastCGI cache, heavy plugins, MySQL slow queries, and image/static asset handling. This article follows a real troubleshooting order: first quantify where it's slow, then optimize PHP, caching, the database, plugins, and front-end assets layer by layer, avoiding blind VPS upgrades.

VPS Self-Hosted Email Going to Spam (2026): Troubleshooting SPF, DKIM, DMARC, PTR, and Bounce Logs

Just because your VPS self-hosted mail server can send email doesn't mean it lands in the inbox. Gmail, Outlook, and Yahoo look at SPF, DKIM, DMARC, PTR/rDNS, HELO, IP reputation, bounce rates, and sending cadence all at once. This article follows a real troubleshooting order: check bounce logs first, then DNS authentication, then confirm PTR and port 25, and finally decide whether it's a configuration problem, an IP reputation problem, or time to switch to an SMTP relay.

How to Run a VPS Backup Restore Drill (2026): restic, rclone, Databases, and Docker Volumes in One Pass

Having a VPS backup doesn't mean you can restore it. A truly reliable backup plan must regularly run restore drills on a clean test machine to confirm that the restic/rclone repository is readable, database dumps can be imported, Docker volumes can be restored, and no configs or keys are missing. This article gives you an executable restore drill checklist for the most common small-site-owner scenario: Docker + MySQL/PostgreSQL + file directories.

What to Do When a VPS Website Is Hit by a CC Attack (2026): Cloudflare WAF, Nginx Rate Limiting, and Origin Protection Emergency Checklist

When a VPS website suddenly shows high CPU, saturated bandwidth, and an Nginx access.log flooded by the same batch of IPs or paths, it is not necessarily a normal traffic surge — it may well be a CC attack, malicious crawler, or API abuse. This article follows the real emergency order: first confirm from logs whether it is an HTTP-layer attack, then use Cloudflare WAF/Rate Limiting to block at the edge, use Nginx limit_req and limit_conn to protect the origin as a fallback, and explain how to avoid harming search engines and normal users.

How to Optimize Low-Memory VPS with ZRAM and Swap (2026): Avoid OOM, Lag, and Disk Thrashing

On 1C1G and 1C2G low-memory VPS running WordPress, Docker, or databases, the most common problem isn't insufficient CPU but persistently high memory pressure, which eventually triggers the OOM Killer or swap thrashing. This article explains the differences between ZRAM, swapfile, and zswap, provides directly executable configuration steps for Debian/Ubuntu, and covers swappiness, priorities, monitoring, and rollback methods.
