The short version

  • Spring Boot is free; Docker starts at $11/mo.
  • Where Docker falls short: shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation.
  • Prices and features on this page were last checked on 13 November 2026.

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

Spring Boot

  • Requires Java 17 as the minimum version for Spring Boot 4.1.0, per docs.spring.io/spring-boot/system-requirements.html (Aug 2026); older Java runtimes are not supported
  • Requires Spring Framework 7.0.8 or above and Gradle 8.14+ or Maven 3.6.3+, per Spring's own system requirements page, so older toolchains must be upgraded first

Questions people ask

Is Docker or Spring Boot better?
Neither clearly leads. Docker starts at Free and Spring Boot at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Docker or Spring Boot?
Docker starts at Free and Spring Boot at Free.
Does Docker or Spring Boot run on more platforms?
Docker runs on Linux, macOS, Windows. Spring Boot runs on Web.
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 Spring Boot is typically brought in for.

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.

Source
Spring Boot: Is Spring Boot free?

Yes, Spring Boot is free and open-source software. The core framework is available without cost, and users can download and use it immediately.

Source
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
Spring Boot: What commercial support is available for Spring Boot?

While Spring Boot itself is free, VMware offers optional commercial support, training, and certification through Spring Academy. Tanzu Spring provides support and binaries for OpenJDK, Spring, and Apache Tomcat through a subscription model for enterprises requiring guaranteed support.

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.
