Docker has been a cornerstone in container technology for over a decade, supporting developers in building, running, and managing containers across major operating systems and cloud providers. Docker Desktop, a popular application with over 16.2 million downloads, enhances these capabilities by incorporating Docker Engine, CLI Client, Docker Compose, and access to Docker Hub, along with introducing Docker Extensions. These extensions, numbering nearly 100, are tools that integrate third-party functionalities directly within Docker Desktop, offering enhancements in debugging, testing, security, and more. Notable extensions include Kong Konnect for managing API gateways, Snyk Container for vulnerability scanning, Grafana for monitoring, Portainer for GUI-based container management, and RedHat OpenShift for deploying and testing apps. Docker Desktop Extensions are free to use, although some may require paid tools for additional features, and can be installed, managed, and updated directly within Docker Desktop across Windows, Mac, or Linux systems. They offer extensive capabilities to streamline workflows and enhance Docker's core features, allowing users to easily integrate with familiar technologies and explore new functionalities.
