The short answer: Use systemd if OpenClaw is your primary service and you want the simplest setup with the lowest overhead. Use Docker if you already run containers on the VPS, or if you want easy rollbacks and isolated environments. Both work well — the wrong choice is mixing them for different services on the same box.
"The best deployment method is the one you will actually maintain. systemd is simpler; Docker is more forgiving. Pick based on your habits, not hype."
| Factor | systemd | Docker |
|---|---|---|
| Setup complexity | Low — one unit file | Medium — Dockerfile or image + compose |
| RAM overhead | ~0 MB extra | 30–80 MB extra |
| Disk overhead | ~0 MB extra | 200–500 MB (base images) |
| Update process | npm update, restart service | docker pull, recreate container |
| Rollback | Manual — git checkout or reinstall | Instant — use old image tag |
| Log access | journalctl -u openclaw | docker logs openclaw |
| Filesystem access | Direct — workspace is on host | Volumes or bind mounts |
| Networking | Direct — bind to any port | Port mapping or Docker network |
| Isolation | Minimal — shares host OS | Good — separate filesystem, PID space |
| Multi-service fit | Fine but manual | Excellent with Compose |
If OpenClaw is the reason you bought the VPS, systemd keeps things lean. No daemon overhead, no volume mapping, no image layers. Your workspace lives at /home/openclaw/.openclaw, logs go to journald, and you manage it with familiar systemctl commands.
On a 1 GB or 2 GB VPS, every megabyte counts. systemd adds essentially zero overhead. Docker's daemon plus container runtime can consume 50–80 MB that you might need for your actual applications.
With systemd, OpenClaw's workspace is just a directory on the host. Editing config files, reading logs, backing up data — it is all native filesystem operations. No volume mounts, no docker cp, no permission headaches.
Our systemd service template gives you a production-ready unit file with hardening and restart policies built in.
If your VPS already has Docker for other services — a database, a monitoring stack, a reverse proxy — adding OpenClaw to the same ecosystem is cleaner. One docker-compose.yml defines everything, one docker compose up -d starts the whole stack.
Docker keeps previous image layers. If an update breaks something, you restart the old container in seconds:
# Rollback: just run the previous tag
docker run -d --name openclaw openclaw/openclaw:v1.2.3With systemd, rollback means finding the old commit, checking it out, and rebuilding. It works, but it takes longer.
Docker gives OpenClaw its own filesystem, its own network namespace, and its own process tree. If something goes wrong, the blast radius is contained. This matters more on shared VPS instances or when you are experimenting.
If you choose Docker, here is a minimal setup using Docker Compose:
# docker-compose.yml
version: '3.8'
services:
openclaw:
image: openclaw/openclaw:latest
container_name: openclaw
restart: unless-stopped
ports:
- "3000:3000"
volumes:
- openclaw-data:/home/openclaw/.openclaw
environment:
- OPENCLAW_GATEWAY_TOKEN=${OPENCLAW_GATEWAY_TOKEN}
- NODE_ENV=production
# Limit RAM to prevent runaway usage
deploy:
resources:
limits:
memory: 512M
volumes:
openclaw-data:Start it:
docker compose up -d
docker compose logs -f openclawIf you choose systemd, see our detailed systemd service template guide. The short version:
# Create the unit file
sudo nano /etc/systemd/system/openclaw.service
# Enable and start
sudo systemctl daemon-reload
sudo systemctl enable --now openclaw
# Check status
sudo systemctl status openclawSome people run OpenClaw via systemd but their database in Docker. This works, but creates headaches:
Pick one ecosystem and stay in it. If you are starting fresh and do not use Docker for anything else, start with systemd. If you are building a multi-service stack, go Docker from day one.
Need a VPS for your OpenClaw deployment? The Hostinger KVM 2 plan (2 vCPU / 8 GB RAM) gives you enough headroom for OpenClaw plus a reverse proxy and a database — whether you go systemd or Docker. The NVMe storage makes both approaches feel fast.
Do you already run Docker containers on this VPS?
├── YES → Run OpenClaw in Docker too
└── NO
├── Will you add more services later (DB, monitoring, etc.)?
│ ├── YES → Start with Docker + Compose
│ └── NO → Use systemd (simpler, lighter)
└── Is your VPS under 2 GB RAM?
├── YES → systemd (save every MB)
└── NO → Either works; pick what you know
