According to a recent Gartner note: “If you are looking at alternative solutions, you must include the opportunity cost of using this solution for your engineering resources. For example, a 100-seat annual subscription to Docker Business without any discounts is currently $25,200. Supporting 100 seats with an open-source alternative is likely to significantly exceed this cost due to the level of engineering resources required to maintain the solution. If you decide to pursue open-source alternatives, you must ensure doing so is a worthwhile use of your engineering resources.”
Docker Desktop has a single installer that sets up everything you need to use Docker in seconds making it seamless to develop on your local machine. Docker also maintains and regularly updates Docker Desktop with bug fixes and security updates. DIY Docker alternatives may require engineering resources to install, configure, patch, and maintain all the components and dependencies, as well as setting up the infrastructure to manage this.
Many training courses are available for Docker, from formal certifications to Youtube videos, as well as comprehensive documentation. Docker Desktop includes a simple user interface to manage all settings. DIY Docker alternatives may lack up-to-date documentation and training, increasing the time it takes to onboard new developers.
Docker Desktop has a lightweight Linux VM that Docker manages for you. As well as setting up this VM, Docker Desktop will keep this VM, and all other components, up to date for you over time by applying kernel patches or other security fixes as are required. DIY Docker alternatives may require engineering resources to keep all components updated and all vulnerabilities patched.
Docker Desktop is a reliable and trusted multi-platform developer tool available on Mac and Windows (Linux coming soon) used by many organizations with hundreds or thousands of developers to build, ship, and run modern cloud-native applications in production, at scale. DIY Docker alternatives may require engineering time to build, configure, and maintain stable development environments.
