Docker に最適な VPS 2026: 8 コンテナホスティングプロバイダーの比較 - JA
付きの最安プラン "容器" in its name is often the one that can't run Docker. Time4VPS と Hostens はどちらも という製品を販売しています。 "コンテナ VPS," どちらも OpenVZ 上に構築します, which shares the host kernel and blocks the features Docker needs. For containers you build and run yourself, KVM (完全仮想化, where your server gets its own kernel) is the line that matters, not the label on the box. This guide sorts eight providers by what actually runs Dockerコンテナ 良い, and at what real cost.
簡単な回答: For most self-hosted Docker work on a budget, Contabo gives the most RAM per dollar (8 GB for about USD 4.95/mo on KVM). For throwaway or CI containers you spin up and kill, Hetzner and Kamatera bill by the hour or minute. For a full managed container stack (registry, クベネフィット, one-click deploys), DigitalOcean の勝利. Hostinger is the easiest start thanks to a bundled Docker Manager.

How We Selected These Docker VPS Providers
Virtualization type was the gate. Docker needs a real kernel for cgroups and namespaces, so any plan built on OpenVZ or LXC got pulled from the Docker-capable shortlist, even when the same brand sells it cheaper. We required KVM仮想化 with full root access on every recommended plan.
そこから, weighting followed the Docker use case. RAM headroom mattered most, since each container eats 512 MBから 2 GB, so we favored plans with 4 GB or more at the entry tier. NVMe or SSD storage counted heavily because image builds and database containers punish slow disks. We checked for hourly or per-minute billing (it changes the math for short-lived containers), one-click Docker tooling, and whether renewal pricing stayed honest.
Sources were official checkout pages first, then independent uptime monitors and user-review aggregators with 50+ レビュー. 合成負荷テストは実行しませんでした, and we flag where renewal pricing wasn't published on a current product page. Where a provider sells both an OpenVZ and a KVM line, we steer you to the one that runs Docker, not the one with the lower sticker price.

Hostinger – Best for a Guided Docker Start
エントリ: USD 6.49/mo on a 24-month term (KVM 1). 1 vCPU, 4 GB RAM, 50 GB NVMe, 4 TBトラフィック. KVM, 完全なルート. で更新します 11.99ドル/月. 30-日帰り.
Hostinger is the only budget host here that bundles a visual Docker Manager into the panel. On most cheap VPS plans you install Portainer yourself; Hostinger ships a container dashboard plus a true one-click Docker template, so you can have an image pulled and running without touching a Compose file. The Kodee AI assistant talks you through setup, which helps if this is your first container host.
RAM is the real draw at the bottom of the range. KVM 1 あなたに手渡します 4 エントリー層の GB, enough for a handful of small containers plus a database. That's where Hostinger beats the convenience-cloud crowd: DigitalOcean charges roughly USD 24/mo for a 4 GB Basic droplet, while Hostinger's 4 GB KVM 1 lists at USD 6.49/mo on the long term. The trade is bandwidth, KVM 1 キャップ 4 TB where Hetzner includes 20 TB.
Performance comes from AMD EPYC cores and NVMe storage across all four KVM tiers, とともに 99.9% 稼働時間SLA. Step up and you get KVM 2 (2 vCPU, 8 GB, 8.99ドル/月, 米ドルを更新します 14.99) またはKVM 4 (4 vCPU, 16 GB, 12.99ドル/月, 米ドルを更新します 28.99).
長所:
- Bundled Docker Manager GUI plus one-click Docker template
- 4 エントリー層の GB RAM, double the usual 2 GB
- AMD EPYC and NVMe on every plan
- Eight data center regions, including Brazil and India
短所:
- 更新は約2倍 (KVM 1: 米ドル 6.49 米ドルへ 11.99)
- Lowest rate needs a 24-month prepay
- No hourly billing for short-lived containers
価格設定: The headline rate buys two years up front. Renewal lands near double, so factor the USD 11.99/mo when you do the math past year two. セットアップ料金なし, free snapshots and weekly backups included.
こんな方に最適: first-time container hosts who want a GUI and a one-click image. 次の場合はスキップします: you want to pay by the hour for ephemeral work.
評決: Buy Hostinger if you're new to Docker and want the panel to hold your hand, the bundled Docker Manager genuinely shortens setup. If you already live in a terminal and want raw value, Contabo gives twice the RAM for less, and if you need hourly billing, Hetzner is the better call.

Kamatera – Best for Throwaway and CI Containers
エントリ: 4ドル/月, 分単位で請求される. Build-your-own (1 に 104 vCPU, 256 MBから 128 GB RAM, NVMe SSD). 30-1 日の無料トライアル (USD まで) 100 クレジット. 99.95% 稼働時間.
Picture a CI pipeline that spins up a Docker host, runs a build, and destroys it twenty minutes later. That's the Kamatera scenario. Billing is per-minute, not per-month, so an ephemeral container box costs cents per run. Better still, Kamatera publishes an official docker-machine driver on GitHub, so the whole lifecycle scripts cleanly into your CI/CD without manual provisioning.
Deployment is a genuine one-click affair: the marketplace carries Docker-ready Ubuntu 24.04 と 22.04 画像, plus Portainer, Harbor, and Kubernetes templates. You pick CPU, 羊, 保管所, and one of 17 global regions independently, then scale any of them mid-flight. For the free window, Kamatera's 30-day trial caps at USD 100 信用度の; DigitalOcean's competing offer hands new users USD 200 以上 60 日々, so DO is more generous on paper, but Kamatera lets you reshape the machine as you go.
正直な注意点が 1 つあります: 米ドル 4 box ships with 1 GB RAM, which is thin for multi-container work. Plan on a 2 に 4 GBビルド (closer to USD 6 to USD 12/mo) for a usable Docker host. これは管理されていないインフラストラクチャです, you get the VM and the support desk, not a managed orchestration layer.
長所:
- 分単位の課金, ideal for short-lived containers
- 正式 docker-machine driver for CI/CD
- One-click Docker images plus Portainer and Harbor
- 17 地域; scale CPU and RAM independently
短所:
- 米ドル 4 entry has only 1 GB RAM
- No managed Kubernetes or container registry
- Config-based pricing creeps as you add resources
価格設定: Pay-as-you-go with no long contract. Hourly and monthly both available. The trial works as the risk-free window since there's no traditional refund policy.
こんな方に最適: developers scripting ephemeral Docker hosts into CI. 次の場合はスキップします: you want a fixed monthly price you never have to think about.
評決: Choose Kamatera when containers are short-lived and you want to automate spin-up and teardown, the docker-machine driver and per-minute billing are built for exactly that. If you want a flat monthly bill and maximum RAM, Contabo is the saner pick, and if you need a managed registry and Kubernetes alongside, DigitalOcean keeps it all in one console.

ホスティング.com (以前の A2 ホスティング) – Best for Distro Choice
エントリ: USD 9.99/月のプロモーション (unmanaged Linux VPS). AMD EPYC, NVMe, KVM, 完全なルート. Regular and renewal rate 19.99ドル/月. VPS plans excluded from the refund window.
悪いニュースから始めましょう, because it's the kind buyers miss. A2 Hosting rebranded to Hosting.com under World Host Group in April 2025, and the current refund policy explicitly excludes VPS plans. So there's no money-back trial for Docker workloads here, a real downgrade from A2's old prorated VPS refund. Sign up only when you're confident the box fits.
What you get for that commitment is a clean unmanaged KVM VPS with full root and your choice of Ubuntu 22.04, Debian 12, またはAlmaLinux 9, all standard Docker hosts. The unmanaged line explicitly markets the freedom to install your own containers, runs on AMD EPYC with NVMe, and carries a 99.9% SLA. If your team standardizes on AlmaLinux for production, this is one of the few budget hosts that offers it cleanly at checkout.
The value question is where it stumbles. Hosting.com's unmanaged VPS renews at USD 19.99/mo, and the page doesn't publish per-tier vCPU and RAM, so you're sizing a container host partly blind. 比較用, Contabo のクラウド VPS 20 gives a known 12 GB RAM at a flat USD 7.95/mo. Avoid the managed cPanel VPS line for Docker, it runs CloudLinux without full root, so containers are off the table there.
長所:
- 選択 Ubuntu, Debian, またはAlmaLinux チェックアウト時
- Unmanaged KVM with full root, AMD EPYC, NVMe
- 10 グローバルデータセンターの所在地
短所:
- VPS plans excluded from the 30-day money-back
- Per-tier specs not published on the product page
- リニューアルダブルス (米ドル 9.99 米ドルへ 19.99)
- Managed cPanel line can't run Docker
価格設定: Promo USD 9.99/mo on a longer term, regular USD 19.99/mo. No risk-free window on VPS, so treat the first bill as committed spend.
こんな方に最適: teams that need AlmaLinux or Debian specifically and know their resource needs. 次の場合はスキップします: you want a refund safety net, Hostinger's 30-day guarantee covers VPS where Hosting.com's does not.
評決: Pick Hosting.com when distro choice and a managed company behind the rebrand matter more than price, and when you're certain about sizing. If you want the same KVM freedom with more published RAM per dollar, Contabo wins outright, and if you need a refund window to test Docker first, ホスティンガーに行く.

Time4VPS – Best Cheap EU Box (the Right Line)
エントリ (Linux VPS, KVM): 1.99ユーロ/月 (約米ドル 2.15), ユーロから 0.99 on a biennial term. 1 vCPU, 2 GB RAM, 20 GB SSD, 4 TBトラフィック. Single Vilnius data center. 99.98% 稼働時間.
Here's the trap this provider sets, and it's the reason this whole guide exists. Time4VPS sells a product literally called "コンテナ VPS," and it's built on OpenVZ 7, which shares the host kernel. Docker won't run reliably on it. The line you actually want for containers is the "Linux VPS," which uses KVM. Same brand, two virtualization types, and the cheaper-sounding one is the wrong buy for Docker.
Get the naming right and Time4VPS is one of the cheapest legitimate Docker boxes in the EU. The KVM Linux 2 tier runs about EUR 1.99/mo for 2 GBのRAM, dropping toward EUR 0.99 on a two-year prepay. That undercuts its own sister brand: Hostens charges roughly USD 3.75/mo for the same 2 GB on a three-year term, while Time4VPS's EUR 1.99 (米ドル 2.15) lands lower for similar hardware out of the same Lithuanian facility. Step up to Linux 4 (2 vCPU, 4 GB, 40 GB) for a comfortable small Docker host around EUR 4.39/mo.
The limits are real. Everything ships from one Vilnius data center, so latency climbs for anyone outside Europe, and there's no geo-redundancy. Default storage on cheaper tiers is SSD rather than NVMe, which slows heavy image builds. A 30-day money-back guarantee covers you while you test.
長所:
- EUR 0.99/mo floor on biennial KVM plans
- Real KVM with full root on the Linux VPS line
- EU/GDPR Tier III facility, 30-当日返金
- Generous traffic (4 に 32 TB by tier)
短所:
- より安い "コンテナ VPS" 走る OpenVZ, not Docker-ready
- 単一のデータセンター (ビリニュスのみ)
- Lowest rates need long prepay
価格設定: Term-based, 毎月から隔年まで. The headline EUR 0.99 needs the two-year commitment; month-to-month sits closer to EUR 1.99. SSD upgrade and add-ons cost extra.
こんな方に最適: EU-based developers wanting the cheapest honest KVM Docker box. 次の場合はスキップします: your users are in the Americas or Asia, where a single Vilnius DC adds latency, look at Kamatera's 17 regions instead.
評決: Buy the Time4VPS Linux VPS (not the Container VPS) if you want rock-bottom EU pricing and you can commit to a term, it's the cheapest properly Docker-capable box on this list. If you need NVMe speed for fast image builds or servers outside Europe, これは違います, point yourself at Contabo or Hetzner.

Hostens – Best for High-Bandwidth Budget Containers
エントリ (Linux VPS, KVM): about USD 3.75/mo on a three-year term (米ドル 7.50 通常). 1 vCPU, 2 GB RAM, 20 GB SSD, 4 TBトラフィック. Single Vilnius data center. 99.95% 稼働時間.
米ドル 3.75 a month for a KVM box with 4 TB のトラフィック. That's Hostens at its cheapest, and like its sister brand Time4VPS, it hides a virtualization trap. The "コンテナ VPS" と "ストレージ VPS" lines run OpenVZ and can't host Docker properly; only the "Linux VPS" tiers use KVM. Buy the Linux line, ignore the container-branded one, same lesson as before.
Where Hostens earns its place is bandwidth-to-price. The Linux tiers bundle 4 に 16 TB of traffic on SSD storage from an EU Tier III facility, which suits container apps that move a lot of data on a tight budget. The ceiling is modest, けれど: the published top tier is LARGE at 3 vCPU と 8 GB RAM for USD 31.50/mo. Put that next to Contabo's Cloud VPS 10, which gives the same 8 GB for about USD 4.95/mo, and Hostens looks expensive once you climb past the entry box. At the very bottom, でも, the 2 GB KVM SMALL tier on a long term is competitive for a single-purpose container host.
Renewal pricing isn't published on the plan page, so the long discounted term carries some uncertainty about what you'll pay later. Expect it to climb back toward the USD 7.50 通常料金.
長所:
- Real KVM on the Linux VPS line, 完全なルート
- High traffic allowances (4 に 16 TB)
- EU/Lithuania Tier III, 30-日帰り
- 安いです 2 GB entry on a three-year term
短所:
- "コンテナ VPS" と "ストレージ VPS" それは OpenVZ, not for Docker
- Low ceiling (最大 3 vCPU / 8 GB 公開)
- Renewal price not published
- One data center, SSD not NVMe
価格設定: Term discounts run 30% (1 年) に 50% (3 年), so the effective rate depends on commitment length. 米ドル 3.75 figure assumes a three-year prepay on the Linux SMALL tier.
こんな方に最適: a single bandwidth-hungry container app on an EU budget. 次の場合はスキップします: you'll need more than 8 GB RAM, the ceiling is low and Contabo scales to 24 GB をさらに安く.
評決: Go with the Hostens Linux VPS for a cheap, high-traffic single container box in the EU, the bandwidth allowances are strong for the money. If you expect to grow past 8 GB of RAM or want published renewal pricing, スキップしてください, Contabo offers more headroom and a flat rate that doesn't surprise you.

Contabo – Best RAM Per Dollar for Self-Hosting
エントリ (クラウドVPS 10): about USD 4.95/mo. 4 vCPU, 8 GB RAM, 75 GB NVMe (また 150 GB SSD), 200 Mbit/秒ポート. KVM, 完全なルート. 更新は横ばい. 99.9% 稼働時間.
Twenty-four gigabytes of RAM for about EUR 14 月. That's the Cloud VPS 30, and it's why self-hosters who run a dozen containers keep landing on Contabo. The whole range is KVM with full root, NVMe storage at no extra cost, and a flat renewal that doesn't jump after a promo. Since Contabo dropped shared hosting in 2025, the VPS line is the focus, and it's built for stacking containers.
Density is the story. エントリーのクラウドVPS 10 パック 8 GB into a USD 4.95/mo box; 同じ 8 GB on Hostens costs USD 31.50/mo, and DigitalOcean's nearest equivalent runs higher still. For one-click Docker, Contabo offers a Coolify VPS image, a self-hosted PaaS that gives you Heroku-style deploys for any Docker-packaged app without wiring up Portainer by hand. You can also point S3-compatible Object Storage at a self-run registry.
正直な弱点: vCPU is shared and can feel variable under load, and port speeds start at 200 Mbit/s on the cheapest tier (上昇する 600 Mbit/s by VPS 30), so throughput-heavy workloads notice. There's no managed Kubernetes and no first-party container registry. 返金窓口はあくまで 14 日々, and reviewers report the refund process is fussy. A small new gotcha: a one-time setup fee now applies to Cloud VPS 10 on 1-month and 6-month terms, longer terms and higher tiers avoid it.
長所:
- 8 GB RAM from USD 4.95/mo, 24 GB near EUR 14
- フラットリニューアル, プロモーションクリフはありません
- NVMe included; one-click Coolify PaaS
- 11 データセンター 9 地域
短所:
- Shared vCPU and 200 Mbit / s entry port
- 14-当日返金, reportedly hard to claim
- No managed Kubernetes or registry
価格設定: About USD 4.95/mo for Cloud VPS 10, 米ドル 7.95 VPS用 20 (12 GB), around EUR 14 VPS用 30 (24 GB). Renewal matches the original rate. Watch the setup fee only on the cheapest tier with short terms.
こんな方に最適: self-hosters cramming many containers onto one cheap, high-RAM box. 次の場合はスキップします: you need consistent dedicated CPU or fast ports, Hetzner's dedicated-vCPU CCX line is steadier under sustained load.
評決: Contabo is the pick when RAM density and a flat bill beat everything else, nobody here gives you 24 GB for EUR 14. If your containers are CPU-bound or latency-sensitive, 他の場所を見てください: Hetzner's dedicated vCPU plans hold up better under constant load, and DigitalOcean wins if you want managed orchestration.

Hetzner – Best for Automated and ARM Container Workloads
エントリ (CAX11, アーム): EUR 5.99/mo (約米ドル 6.49), billed hourly. 2 vCPU, 4 GB RAM, 40 GB NVMe, 20 TBトラフィック. KVM, 完全なルート. IPv4 adds about EUR 0.50/mo. 99.9% 稼働時間.
Where DigitalOcean sells you a console, Hetzner sells you an API. The Cloud platform pairs raw KVM VMs with a full REST API, the hcloud CLI, an official Terraform provider, and Ansible support, so your Docker infrastructure becomes code you commit. Add hourly billing capped at a monthly max, and short-lived container clusters cost only the hours they run.
The ARM CAX line is the quiet value play for containers. CAX11 gives 2 Ampere cores and 4 GB RAM with a remarkable 20 TB of included traffic for EUR 5.99/mo. Hostinger matches the 4 GB（USD） 6.49, but caps traffic at 4 TB, so Hetzner offers five times the bandwidth at a near-identical price. Multi-arch Docker images run natively on ARM, often cheaper than x86. Prefer Intel or AMD? CX23 (インテル, 4 GB) lists around EUR 5.49 and CPX22 (AMD) bumps storage to 80 GB. There's a one-click Docker app in the marketplace too.
A note on timing: Hetzner raised Cloud prices on June 15, 2026, so the once-dramatic gap narrowed (entry ARM went from about EUR 4.49 ユーロです 5.99). Support is email-only, there's no managed Kubernetes, and IPv4 now carries a small monthly fee. For constant high-CPU container loads, the dedicated-vCPU CCX line (from CCX13, 2 vCPU, 8 GB) is the steadier choice.
長所:
- 満杯 API, コマンドライン, and Terraform for IaC
- 20 TBトラフィック included on EU plans
- Cheap ARM cores for multi-arch containers
- 時間単位の請求; one-click Docker app
短所:
- No managed Kubernetes or container service
- IPv4 costs extra; email-only support
- 六月 2026 price rise narrowed the value gap
価格設定: EUR 5.99/mo CAX11 (アーム), ユーロ 5.49 CX23 (インテル), both hourly-capped. Add roughly EUR 0.50/mo if you need an IPv4 address. No fixed-term contract, so you stop paying when you delete the server.
こんな方に最適: developers who script infrastructure and want ARM value plus huge bandwidth. 次の場合はスキップします: you want phone support or a managed container platform, DigitalOcean offers both where Hetzner offers neither.
評決: Hetzner is the automation pick, treat servers as disposable code and the API plus hourly billing pays off fast. If you'd rather click through a managed Kubernetes setup or call support, DigitalOcean fits better, and if flat-rate maximum RAM is the goal, Contabo undercuts Hetzner on memory per dollar.

DigitalOcean – Best Managed Container Stack
エントリ (Basic droplet): 4ドル/月, billed per second with a monthly cap. 1 vCPU, 512 MB RAM, 10 GB SSD, 500 GB転送. 米ドル 200 の功績 60 日々. 99.99% droplet SLA.
The whole container toolchain lives in one console here, and that's the reason to pay a little more. DigitalOcean gives you a one-click Docker droplet, マネージドKubernetes (ドキュメント), a container registry (DOCR), and App Platform, all wired together, so your cluster can pull straight from your private registry without glue code. The standout cost edge: the DOKS control plane is free, where hyperscalers charge roughly USD 0.10/hr per cluster. You pay only for worker-node droplets, with clusters starting around USD 12/mo.
This is also where managed Kubernetes can beat a raw Docker VPS for small teams. The registry has a free Starter tier (500 MB), 基本料金 USD 5/月, and Pro at USD 20/mo, and App Platform builds and deploys straight from a Dockerfile if you'd rather skip server management entirely. For a small team that doesn't want to babysit a control plane, that bundle is worth real money.
Raw compute is the weak spot. 米ドル 4 droplet's 512 MB is too small for real containers, so practical Docker work starts at USD 12 to USD 24/mo. A 2 GB droplet runs USD 12, while Hetzner's CX23 gives 4 GBで約USD 5.90: twice the RAM at half the price. You pay that premium for the managed ecosystem and the 99.99% droplet SLA, not for cheap memory. Fourteen data centers across 11 regions cover most of the globe.
長所:
- 無料の Kubernetes コントロール プレーン (ドキュメント)
- Integrated registry, アプリプラットフォーム, one-click Docker
- 秒単位の課金; 米ドル 200 new-user credit
- 99.99% droplet SLA, strong docs and API
短所:
- エントリ 512 MB droplet too small for Docker
- Roughly 4x Hetzner's cost per GB of RAM
- No always-free tier after the credit expires
価格設定: ドロップレットは月額 4 米ドルから (realistic Docker from USD 12), DOKS worker nodes billed as droplets with a free control plane, registry free to USD 20/mo. The USD 200/60-day credit covers a generous trial period.
こんな方に最適: teams that want managed Kubernetes, a registry, and deploys in one place. 次の場合はスキップします: you're optimizing for cheap RAM on a single box, Contabo gives 8 GB for the price of DO's 1 GB 層.
評決: DigitalOcean wins when you want the managed container stack and the free Kubernetes control plane, the integration saves real engineering time. If your project is one self-managed Docker host and budget rules, Contabo or Hetzner deliver far more compute per dollar, and the difference compounds every month.
How to Choose a Docker VPS
This isn't about feature checklists. It's about matching the workload to the billing model and the RAM. 3 つのシナリオでほとんどの購入者をカバー.
Long-running self-hosted stack (10+ コンテナ), 予算は月あたり 15 米ドル未満. Go Contabo Cloud VPS 30 (24 GB RAM, about EUR 14/mo). Skip DigitalOcean here, a comparable 24 GB of managed droplet RAM costs several times more, and for a single always-on box you don't need the orchestration layer you'd be paying for.
Ephemeral CI builds or test containers spun up and destroyed. Use Kamatera (毎分) or Hetzner (毎時, Terraform を使用して). A build host that lives 20 minutes shouldn't cost a full month. Both let you script creation and teardown; Hetzner's API and hcloud CLI edge ahead if your pipeline is already infrastructure-as-code. Don't park this on a term-locked plan like Time4VPS, you'd pay for idle months.
Budget under USD 4/mo, EU users, single container app. Pick the Time4VPS Linux VPS (KVM), from EUR 1.99/mo, not the cheaper "コンテナ VPS" (OpenVZ won't run Docker). If you're outside Europe, this single-DC option adds latency, choose Kamatera's nearest of 17 regions instead.
Managed registry plus Kubernetes, without running your own control plane. DigitalOcean is the answer, the free DOKS control plane and integrated DOCR remove work that you'd otherwise do by hand on Hetzner or Contabo. When containers outgrow a single VPS entirely and you need guaranteed isolated hardware, that's the point to compare a dedicated server 代わりは.
1 つのルールがこれらすべてに適用されます: confirm KVM before you buy. If a plan says OpenVZ, ルクセンブルク, また "コンテナ," assume Docker will fight you. The brands above that sell both lines (Time4VPS, Hostens) make this mistake easy, so read the spec, not the product name.
Think about where Docker sits in your scaling path, それも. Shared hosting can't run it at all (no root, shared kernel), which is the usual reason people move to a VPS in the first place. A single KVM box covers most projects for a long time. When traffic gets spiky or global and you'd rather not manage scaling by hand, that's the moment a managed cloud platform or an orchestrated cluster starts earning its higher price. それまでは, a plain Docker VPS is almost always the cheaper, simpler call.
よくある質問
Can I run Docker on the cheapest "コンテナ VPS" 予定?
通常はそうではありません. Products named "コンテナ VPS" from Time4VPS and Hostens run on OpenVZ, which shares the host kernel and blocks the features Docker needs. For Docker you want their KVM "Linux VPS" line instead. The naming is backwards: the plan branded for containers is the one that can't run yours.
How much RAM do I need to run multiple Docker containers?
バジェット 512 MBから 2 GB per container, so a small multi-container stack wants at least 4 GB. ホスティンガーのKVM 1 (4 GB) and Hetzner's CAX11 (4 GB) handle a handful of containers plus a database. 為に 10 or more services, jump to Contabo's 8 に 24 GB tiers. The 512 MB entry droplets from DigitalOcean are too thin for real Docker work.
Which VPS comes with Docker preinstalled?
Hostinger bundles a Docker Manager GUI and a one-click Docker template. Hetzner and DigitalOcean both offer one-click Docker images in their marketplaces, and Kamatera ships Docker-ready Ubuntu images plus a docker-machine driver. Contabo offers a one-click Coolify image, a self-hosted PaaS for Docker apps. On bare KVM elsewhere, you install Docker yourself in a couple of commands.
Is managed Kubernetes cheaper than running Docker on a VPS?
かもね, for small clusters. DigitalOcean's DOKS control plane is free, so you pay only for worker-node droplets (clusters from about USD 12/mo). Most hyperscalers charge roughly USD 0.10/hr just for the control plane. For a single host running a few containers, a plain Contabo or Hetzner VPS is still cheaper, but once you need orchestration and failover, DOKS removes a lot of cost and effort.
最終評決
Match the provider to how your containers behave. For a long-running, high-density self-hosted stack on a budget, コンタボ 明らかに勝者です: 8 GB for USD 4.95/mo and 24 GB near EUR 14, on flat-renewing KVM. For containers you spin up and kill, ヘッツナー (毎時, scriptable, 20 TBトラフィック) と カマテラ (毎分, docker-machine driver) split the win, lean Hetzner if your pipeline is infrastructure-as-code. When you want a managed registry and Kubernetes in one console, DigitalOcean takes it on the free control plane alone.
For a guided first container host, Hostinger's bundled Docker Manager is the gentlest on-ramp. Need a specific distro like AlmaLinux and you're sure of your sizing? ホスティング.com 作品, just remember VPS plans skip the refund window. And for the cheapest honest EU box, the Time4VPS と Hostens Linux (KVM) lines deliver, as long as you avoid their OpenVZ "コンテナ VPS" 予定, which can't run Docker at all.
