Tink vs containerd
containerd is the CNCF container runtime. It also records ctr containers. That is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
containerd runs the shim. Tink answers “why is this VPS sick?”
Accidental sysadmins land on containerd because Docker and Kubernetes both sit on it. Then the volume fills, host nginx dies, and crictl ps still shows Running — no task matched host fill. A filling /var is a Tink warning; it is not a containerd job unless you scraped the metrics endpoint and watched it.
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 using containerd if you already run a CRI runtime. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | containerd |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Hours — CRI sockets, snapshotters, runtimes, and a host that still has no mechanic after ctr containers looks fine |
| What you get | Working monitoring, diagnosis, and approved fixes | A container runtime. Disk fill, host nginx, Postgres, and certs stay your problem until you SSH in |
| Pricing | Free (Scout) / $9 / $29 per machine per month | containerd is free and CNCF-hosted. You still pay the engineer who owns the node after the shim started |
| Hidden costs | None — fully managed | A quiet node at 2am, overlay disk fill, and a second tool to tell you the VPS is sick while crictl ps still shows Running |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Task status and containerd metrics. containerd does not watch a quiet cert or host auth.log after the shim started |
| Configuration | None after install — heuristics and AI | config.toml, CRI plugins, snapshotters, and which container death actually pages you |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | You read ctr logs and crictl inspect, then SSH in to change the host containerd already started |
| Fix execution | Proposes and executes approved commands with an audit trail | Stop and start only — containerd cannot free host disk, rotate a cert, or stop SSH brute-force unless you wrote that runbook |
| Alerting | Built-in across 8 channels | Not a containerd job — CRI liveness, kubelet, and a separate monitoring tool have to fire |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Not a containerd job — a green crictl ps does not forecast a quiet volume filling up |
| SSH brute-force detection | Built-in — parses auth.log every scan | Never — containerd does not read host auth.log, journald, or firewall state after the shim started |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | Silence if the box dies after the last crictl ps — unless you built a separate uptime check |
| Public status page | Shareable URL with 90-day history | None — containerd has no customer-facing status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | None — a ctr containers recap is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire failed tasks into PagerDuty or another incident tool |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | ctr and crictl. No mechanic you text when /var filled and the last task still showed Running |
| Learning curve | None — works after install | Steep — CRI, snapshotters, shims, namespaces, and which host failure is the runtime vs the running box |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Teams that already run a CRI runtime and need a shim, not a sick-VPS mechanic |
When containerd is the right choice
Keep using containerd when you already want that exact job:
- CRI container runtime — you need shims, snapshotters, and a kubelet socket, not a mechanic.
- An existing containerd node — CRI plugins, namespaces, and image pulls matter more than host nginx, certs, and SSH on a quiet VPS.
- An existing Kubernetes or Docker host — tasks already start, the runtime already ships, and someone owns the shim.
- Hosts that only page on failed tasks — you already run exporters and PromQL, not a sick-box SSH loop.
The real cost of “just run ctr containers”
containerd is the runtime under Docker and every kubelet. A working ops loop for five Linux boxes is not:
- A green crictl ps still means you SSH in and change the box by hand when it gets sick later
- Host fill, nginx, certs, and SSH brute-force never appear unless a separate tool scraped those signals and a rule fired
- A filling /var is a Tink disk warning on every scan — containerd will stay quiet until the next CRI probe
- A single VPS with a dead agent still needs a mechanic, not another ctr metrics line
For a 5-server team, Tink Mechanic at $45/month is cheaper than a containerd node plus the engineer who keeps failed-task notifications alive, and every scan includes a diagnosis a quiet crictl ps will not type.
No CRI homework. No silent host. One command install.
