About Docker

**Docker** is the industry-standard platform for building, shipping, and running applications in containers—lightweight, portable, self-sufficient packages that include everything needed to run software: code, runtime, libraries, and dependencies. With over 20 million developers and 11 billion monthly image downloads, Docker has fundamentally changed how software is developed and deployed. The platform ensures that applications work identically across development, testing, and production environments, eliminating the infamous "it works on my machine" problem. Docker has recently expanded into AI/agent development with Docker Model Runner for local LLM inference and MCP (Model Context Protocol) support for building AI agents. **Category:** Containerization Platform / Development Tools / DevOps Infrastructure / Application Deployment **Webstudio Integration:** Docker doesn't integrate directly with Webstudio's visual editor, but it's essential infrastructure for self-hosting complementary services. Use Docker to run headless CMS systems (Directus, Strapi, Payload), analytics platforms (Umami, Plausible, Matomo), form backends, or any API services that feed data into your Webstudio projects via Resources. Docker is also how you'd **self-host Webstudio itself**—Webstudio is open source and can be deployed via Docker containers for full control over your infrastructure. For local development, Docker Desktop lets you spin up databases, CMS instances, and backend services that your Webstudio site connects to. Many services that integrate with Webstudio (like Formbricks, Listmonk, or N8N) provide official Docker images for self-hosting. **Strengths:** Industry standard with unmatched ecosystem—virtually every modern application provides Docker images. Docker Hub hosts 14+ million container images, making it trivial to deploy complex software stacks. "Build once, run anywhere" portability means your containerized services work identically on your laptop, VPS, or cloud provider. Docker Compose enables defining multi-service applications in a single YAML file. Excellent documentation and massive community support. Docker Desktop provides a polished GUI for managing containers on Windows, Mac, and Linux. Recent additions include Docker Scout for vulnerability scanning, Docker Build Cloud for faster CI/CD builds (up to 39x faster), and Testcontainers for integration testing. Docker Hardened Images offer near-zero CVE base images with 7-day SLA for critical vulnerability remediation. The new MCP Catalog provides 200+ verified servers for AI agent development. **Weaknesses:** Learning curve for developers new to containerization concepts. Docker Desktop requires a paid subscription for commercial use in organizations with 250+ employees or $10M+ revenue (though Docker Engine itself remains free). Recent pricing increases (Pro up 80%, Team up 67% as of December 2024) have frustrated some users. Can add complexity for simple projects that don't need containerization. Resource overhead on development machines—Docker Desktop can consume significant RAM. Some users report occasional performance issues on macOS. Image pull rate limits on Docker Hub may affect high-volume users on free tiers. **Pricing:** **Docker Personal** (free) includes Docker Desktop, unlimited public repositories, 200 image pulls/6 hours, community support—free for individuals, education, non-commercial open source, and small businesses (<250 employees, <$10M revenue). **Docker Pro** is $9/month (annual) or $11/month (monthly) for individuals needing more—includes 5,000 pulls/day, unlimited private repos, 200 Build Cloud minutes, 100 Testcontainers Cloud minutes. **Docker Team** is $15/user/month (annual) or $16/user/month (monthly) for up to 100 users with collaboration features, RBAC, audit logs, unlimited Scout repos. **Docker Business** is $24/user/month with enterprise features: SSO/SCIM, SOC 2 Type 2 compliance, hardened desktop, centralized management. Docker Hub consumption pricing (effective March 2025) adds charges for image pulls and storage beyond plan limits.
