About Docker
Docker was founded in 2010 by Solomon Hykes, originally under the name dotCloud as a platform-as-a-service company, before pivoting in 2013 to focus on and open-source Docker, a container technology the company had built internally that quickly became one of the most consequential and widely adopted pieces of developer infrastructure of the past decade. Containers, the core technology Docker helped popularize, package an application together with all of its dependencies, libraries, and configuration into a single, portable unit that runs consistently whether on a developer's laptop, a company's internal servers, or any major cloud provider, addressing the long-standing "it works on my machine" problem where software behaves differently across different computing environments due to subtle differences in installed dependencies and configuration.
Docker's technology became foundational infrastructure underlying the broader shift toward microservices architectures and modern cloud-native application development, and while Docker containers are frequently used alongside Kubernetes, the container orchestration system that manages how many containers are deployed and scaled across a cluster of servers, Docker itself focused primarily on the container packaging and local development experience rather than large-scale orchestration, an area where Google-originated Kubernetes came to dominate. After struggling to build a sustainable enterprise business model around its open-source technology in its earlier years, including selling its enterprise business division to Mirantis in 2019, Docker refocused its commercial strategy around Docker Desktop, a widely used application that lets developers build and run containers locally on their own machines, and Docker Hub, a registry service for storing and sharing container images, monetizing primarily through subscriptions for professional and enterprise use of these developer tools. Docker has raised substantial venture funding over its history from investors including Insight Partners, Benchmark, and Sequoia Capital, and the underlying Docker container format and tooling remain deeply embedded in modern software development practices industry-wide.
