The short version

  • Each has a real cost: Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation; Hetzner Cloud cost-Optimized plans are shown as currently unavailable
  • They diverge on capability: Docker covers Container runtime, Hetzner Cloud covers Cloud servers.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Docker

  • Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • Daemon socket exposure grants full root access to the host if compromised
  • Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
  • Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
  • Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments

Hetzner Cloud

  • Cost-Optimized plans are shown as currently unavailable
  • The shared-resource tiers are positioned for variable usage and development rather than sustained production workloads
  • Regions are limited to Germany, Finland, the United States and Singapore, so latency to other markets is a real constraint
  • The uptime guarantee is 99.9 percent, below what the large hyperscalers offer on comparable services
  • Support is 24/7 by email, without a phone channel

Questions people ask

Is Docker or Hetzner Cloud better?
Neither clearly leads. Docker starts at Free and Hetzner Cloud at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Docker or Hetzner Cloud?
Docker starts at Free and Hetzner Cloud at Free.
Does Docker or Hetzner Cloud run on more platforms?
Docker runs on Linux, macOS, Windows. Hetzner Cloud runs on Web, Api, Cli.
Can I use Docker for free?
Both have a free tier, so you can try either at no cost before committing.
What is Docker best used for?
Docker is most often used for application containerization, microservices, ci/cd pipelines, development environments. Of those, application containerization and microservices are not what Hetzner Cloud is typically brought in for.
What can Docker do that Hetzner Cloud cannot?

Answered from the vendors’ own pages

Docker: What is Docker pricing?

Docker offers a freemium model with Docker Personal free, Docker Pro at $11/user/month, Docker Team at $16/user/month, and Docker Business at $24/user/month. Each tier includes Docker Desktop, Docker Hub, and Docker Scout with different usage limits.

Docker: Can I use Docker in production?

Yes. Docker is used extensively in production environments. However, for container orchestration at scale, Kubernetes is typically paired with Docker to automate deployment, scaling, and management across clusters.

Source
Docker: What are the main security concerns with Docker?

Key security risks include container breakout vulnerabilities through shared kernel exploits, daemon socket exposure that grants root access if compromised, weak isolation between containers, and credential leakage if secrets are embedded in images.

Source
Docker: Does Docker integrate with CI/CD systems?

Yes. Docker integrates with Jenkins, GitHub, and other CI/CD systems. The typical workflow involves GitHub repositories triggering automated builds in Jenkins, which prepare Dockerfiles and push images to Docker Hub for deployment.
