Running Docker on a VPS is not complicated — but the choice of provider determines whether your containers run smoothly or crawl due to CPU steal, bad I/O, or insufficient RAM. This guide covers what Docker actually needs from a VPS, which providers deliver it, and where the community has landed after two years of practical experience.
What Docker Actually Requires From Your VPS
Before comparing providers, the technical requirements matter—especially if you're still evaluating VPS vs dedicated hosting and determining which infrastructure model is best for your Docker workloads.
KVM virtualization is mandatory. Docker requires kernel-level access and namespace isolation. OpenVZ-based VPS providers — where you share a kernel with other tenants — block Docker or run it in a degraded state. Every provider in this guide uses KVM.
RAM is the primary constraint. A single-app Docker container needs 512 MB–2 GB. A realistic Docker Compose stack (application + PostgreSQL + Redis + reverse proxy) needs 4–8 GB. Plan for headroom, not for the minimum.
NVMe storage matters for I/O-bound workloads. Docker volumes for databases write frequently. SATA SSD handles most use cases; HDD does not. On IOPS-limited nodes (Contabo, for example, caps at ~1.3k IOPS), a PostgreSQL container under load degrades noticeably.
CPU steal is a real problem on oversold hosts. Docker containers on a VPS where the host is overselling CPU experience inconsistent build times, database query slowdowns, and response latency spikes. This is the primary reason the community has moved away from Contabo for Docker workloads.
Minimum recommended specs for Docker:
- Single container app: 1–2 vCPU, 2–4 GB RAM, 20 GB NVMe
- Multi-container Compose stack: 2 vCPU, 4 GB RAM, 40 GB NVMe
- Full stack with database volumes: 4 vCPU, 8 GB RAM, 80 GB+ NVMe
Best VPS for Docker in 2026 — Quick Comparison
| Provider | Entry Plan | RAM | Storage | EU Available | Docker Support |
| Hetzner CX22 | €3.79/mo | 4 GB | 40 GB NVMe | DE, FI | Full KVM |
| THE.Hosting | €5.77/mo | 1 GB | 25 GB NVMe | 50+ locations | Full KVM |
| Vultr High Performance | $6/mo | 1 GB | 25 GB NVMe | 9 EU cities | Full KVM |

1. Hetzner — The Community Choice for Docker Hosting
Community consensus across r/selfhosted, LowEndTalk, and Hacker News is consistent: Hetzner is the default recommendation for Docker and Docker Compose deployments. The reason is the specs-per-euro ratio.
The CX22 plan (€3.79/month) delivers 4 GB RAM, 2 vCPUs, and 40 GB NVMe — enough to run a realistic multi-container Compose stack comfortably. For comparison, DigitalOcean's equivalent configuration costs approximately €12–15/month. For teams running 3–5 Docker Compose stacks, this difference compounds quickly.
Hetzner runs KVM virtualization with 10 Gbps uplinks and 20 TB monthly traffic on entry plans. The infrastructure is ISO/IEC 27001 and BSI C5 certified. For Docker specifically: no IOPS throttling, no CPU steal reports at the scale seen with Contabo, full kernel access for custom networking configurations.
The Kube-Hetzner Terraform module (community-built) makes Kubernetes on Hetzner nearly one-command to deploy — relevant if your Docker Compose setup is growing toward orchestration.
Recommended plans for Docker:
- CX22 (€3.79/mo): 2 vCPU, 4 GB RAM, 40 GB NVMe — single-stack production or dev environment
- CPX21 (€4.99/mo): 3 vCPU, 4 GB RAM, 80 GB NVMe — Compose stack with heavier storage requirements
- CPX31 (~€9/mo): 4 vCPU, 8 GB RAM, 160 GB NVMe — multi-stack or database-heavy Compose deployment
Best for: Production Docker and Docker Compose deployments in Germany or Finland. The default pick when you want serious infrastructure without paying for it.
2. THE.Hosting — For Docker Across Multiple Locations
THE.Hosting runs full KVM virtualization on NVMe hardware across 50+ global data centers. For Docker deployments, the infrastructure delivers what matters: full kernel access, NVMe I/O, ECC RAM, and 10 Gbps uplinks — with unlimited traffic at every location.
Plans start at €5.77/month (1 vCPU, 1 GB RAM, 25 GB NVMe). For a real Docker Compose stack with a database, step up to a plan with 4+ GB RAM — the hardware tier remains the same across all locations.
The specific value for Docker users: if you need to run container infrastructure in multiple EU cities — Frankfurt and Amsterdam, or Amsterdam and Warsaw — you can do it from a single provider with consistent hardware and pricing, rather than managing accounts across multiple providers or accepting performance inconsistency.
Unlimited traffic is particularly relevant for Docker-based microservices that generate significant inter-service and external traffic.
Key Docker-relevant features:
- Full KVM — all Docker networking modes supported, no kernel restrictions
- NVMe — I/O consistent across all locations, no SATA-SSD surprise
- ECC RAM — data integrity for persistent volumes
- 50+ locations — deploy close to your actual users
- Unlimited traffic — no cap surprises as your containers scale
Best for: Teams that need Docker infrastructure in multiple EU or global cities, or who want consistent hardware specs across all their nodes without managing multiple provider accounts.
3. Vultr — For Hourly Billing and Multi-City Docker
Vultr is the right choice when you need Docker infrastructure across many EU cities and want to pay by the hour — useful for testing environments, staging clusters, or workloads that run for hours rather than months.
The High Performance tier (1 GB RAM, 25 GB NVMe, 2 TB bandwidth, $6/month) is available in 9 EU cities. Docker runs without any restrictions. One-click Docker application deployments are available for developers who want a starting point rather than a blank VPS.
Vultr's strength vs. Hetzner is geographic breadth — London, Manchester, Madrid, Milan, Paris, Stockholm, and Warsaw extend coverage across Southern and Western Europe where Hetzner has no data centers. If your Docker stack serves users in Spain, Italy, or Poland and latency is a consideration, Vultr's EU footprint is more useful than Hetzner's Germany-Finland coverage.
Recommended for Docker:
- High Performance 2 GB ($12/month): 2 vCPU, 2 GB RAM, 55 GB NVMe, 3 TB bandwidth — realistic single-stack production environment
- High Performance 4 GB ($24/month): 2 vCPU, 4 GB RAM, 80 GB NVMe — multi-container Compose with database
Best for: Multi-city EU Docker deployments, staging environments on hourly billing, or teams that need consistent infrastructure across Western and Southern European cities.
4. OVHcloud — For Bandwidth-Intensive Docker Workloads
OVHcloud's VPS line offers competitive pricing in the mid-tier, particularly for workloads that generate high outbound traffic. Their entry VPS delivers 2 GB RAM, 40 GB NVMe, and unlimited bandwidth for approximately $4.20/month on annual billing.
For Docker deployments that pull large images frequently, serve media files, or handle high-volume API traffic, the unlimited bandwidth without overage charges is a practical advantage. OVHcloud includes DDoS protection standard — useful for public-facing Docker services.
EU locations: Strasbourg and Gravelines (France), Frankfurt (Germany), London (UK), Warsaw (Poland). Full KVM virtualization on all plans.
Community recommendation: OVHcloud is frequently cited in r/selfhosted for Docker stacks running media servers and content delivery workloads where bandwidth is the primary cost driver.
Recommended plan:
- VPS Starter (~$4.20/mo): 1 vCPU, 2 GB RAM, 40 GB NVMe, unlimited bandwidth — entry-level Docker Compose
- VPS Essential (~$7.99/mo): 2 vCPU, 4 GB RAM, 80 GB NVMe — realistic multi-container production
Best for: Docker workloads where bandwidth is the primary concern — media serving, content platforms, or high-volume API backends where per-GB charges would add up quickly.
5. DigitalOcean — For Teams Already in the Ecosystem
DigitalOcean is not the most cost-effective option for Docker, but it remains a legitimate choice for teams already using their managed services (App Platform, managed databases, Spaces object storage) and for developers who value the quality of their documentation.
The marketplace includes Docker-ready Droplet images and 1-click deploy options that reduce setup time. The General Purpose tier (1 GB RAM, 25 GB NVMe, starting at $6/month) runs KVM with full Docker support and per-second billing since January 2026.
For teams where infrastructure cost is less important than the managed service ecosystem and developer onboarding speed, DigitalOcean's Docker support is complete and the tooling is genuinely good.
Caveats: DigitalOcean is 60–80% more expensive than Hetzner or THE.Hosting for equivalent raw compute. If you're purely running Docker without needing managed databases, App Platform, or the Kubernetes managed control plane, the premium is difficult to justify.
Best for: Teams already using DigitalOcean's managed services ecosystem, or companies where the Docker documentation quality and 1-click deploys meaningfully reduce onboarding time.
The Contabo Warning for Docker Users
Contabo appears in Docker discussions because of the RAM-per-dollar pitch. 8 GB RAM at ~€4.50/month is hard to ignore. The Docker-specific problem:
- VPSBenchmarks F-grade (2.9/20) for performance stability — Docker build times are directly affected
- IOPS capped at approximately 1.3k (~4 MB/s for 4K random read/write) — PostgreSQL, MySQL, and Redis volumes all hit this ceiling under load
- CPU steal of 20–40% during business hours — reported by multiple users running build pipelines and container workloads
- Community quote, LowEndTalk 2024: "Contabo's Cloud VPS 30 with 8 vCPU cores performs worse than Hetzner's CX22 with 2 vCPU cores."
If you try Contabo for Docker and find builds taking 10x longer than expected, this is why.
Which VPS for Docker Should You Choose?
| Situation | Best Pick |
| Production Docker in Germany/Finland — best price | Hetzner CX22 or CPX21 |
| Docker across multiple EU cities or globally | THE.Hosting with KVM + NVMe |
| Hourly billing for dev/staging environments | Vultr High Performance |
| Bandwidth-heavy Docker workloads | OVHcloud |
| Already using DigitalOcean managed services | DigitalOcean General Purpose |
| Maximum RAM on a minimal budget | Not Contabo — see Hetzner |
For most developers running Docker on a VPS, the answer is Hetzner or THE.Hosting depending on whether you need Germany/Finland specifically or geographic flexibility across more locations. Both provide KVM, NVMe storage, and infrastructure quality that makes Docker deployments straightforward and predictable.
