Tink vs ingress-nginx
ingress-nginx is a Kubernetes Ingress controller. It watches Ingress objects, then routes HTTP to Services. That is not a mechanic. Tink installs in one command, watches the Linux server, explains what is wrong, and helps you fix it.
ingress-nginx routes HTTP. Tink answers “why is this VPS sick?”
Accidental sysadmins land on ingress-nginx because every Kubernetes traffic diagram mentions it. Then the volume fills, host nginx dies, and Ingress still says 200 — the VPS was never a Service. A filling /var is a Tink warning; it is not an Ingress path unless you already run a cluster.
Tink is the other job: detect the issue on the machine, say why it happened in plain English, propose the command, and run it only after you approve. Keep ingress-nginx if you already operate Kubernetes and need HTTP routing. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | ingress-nginx |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Hours — a cluster, IngressClass, TLS secrets, and still no host mechanic |
| What you get | Working monitoring, diagnosis, and approved fixes | HTTP routes to Services. The box is still yours to diagnose and SSH |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Free (open source). You still pay for the cluster, LoadBalancer, and the engineer who owns Ingress objects |
| Hidden costs | None — fully managed | Annotation sprawl, reload storms, cert rotation, and a second tool that pages you when /var fills |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Request routing from Ingress objects — ingress-nginx does not watch the OS |
| Configuration | None after install — heuristics and AI | Ingress rules, annotations, ConfigMap, admission webhook, and which Service the controller is allowed to expose |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | No — ingress-nginx logs 502s. You still SSH or kubectl logs to learn why a VPS is sick |
| Fix execution | Proposes and executes approved commands with an audit trail | Route only — ingress-nginx cannot free disk, restart host nginx, or rotate a cert on a VPS |
| Alerting | Built-in across 8 channels | None — scrape controller metrics or watch Pod restarts before anyone is paged about the host |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Never — ingress-nginx answers HTTP after traffic already arrived. It does not forecast host fill |
| SSH brute-force detection | Built-in — parses auth.log every scan | Never — ingress-nginx does not read auth.log, journald SSH, or host firewall state |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | A silent Ingress is a missing controller — only if the API server still answers |
| Public status page | Shareable URL with 90-day history | None — ingress-nginx has no customer-facing status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | None — an Ingress reload is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire controller metrics into PagerDuty or another incident tool |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | kubectl get ingress. No mechanic you text when /var filled on a VPS that is not a Service |
| Learning curve | None — works after install | Steep — Kubernetes, IngressClass, TLS secrets, annotation keys, and which 502 actually means the box is sick |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Teams that already run Kubernetes and need HTTP routing, not a sick-VPS mechanic |
When ingress-nginx is the right choice
Keep ingress-nginx when you already want that exact job:
- HTTP routing — ingress-nginx is how Kubernetes exposes a Service on a hostname. You need it to terminate TLS at the cluster edge, not to watch a quiet VPS.
- An existing cluster — IngressClass, TLS secrets, and Ingress objects already exist, and someone owns the annotations.
- Traffic questions — path rules and upstream Services matter more than host nginx, certs, and SSH.
- Hosts that only exist as Nodes — you already run Kubernetes, not a sick-box SSH loop.
The real cost of “just run ingress-nginx”
ingress-nginx is in every Kubernetes traffic diagram. A working ops loop for five Linux boxes is not:
- A 502 still means you SSH in and change the box by hand
- Host fill, nginx, certs, and SSH brute-force never appear unless they show up as controller CPU you already scrape
- A filling /var is a Tink disk warning on every scan — ingress-nginx will stay quiet until the upstream already failed
- A single VPS with no cluster still needs a mechanic, not an Ingress controller
For a 5-server team, Tink Mechanic at $45/month is cheaper than ingress-nginx plus the engineer who keeps Ingress annotations and TLS secrets alive, and every scan includes a diagnosis a quiet 200 from the controller will not type.
No Ingress-annotation homework. No silent host. One command install.
