Docker: Containerization Platform for Fast & Reliable App Development
Discover Docker, an open platform for developing, shipping, and running applications. Learn how containers enable fast and reliable app development with standardized executable components.
What is Docker?
Docker is an open platform for developing, shipping, and running applications inside software containers. It provides an additional layer of abstraction and automation of operating-system-level virtualization on Linux, Mac OS and Windows.
Docker packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime. Using containers, Docker allows applications to run quickly and reliably from one computing environment to another. This avoids dependency conflicts as the software along with dependencies and configuration are bundled together.
Developers can create Docker containers without having to provision and manage infrastructure. Docker provides the tools and platform to build, run and manage containers. With Docker, organizations can accelerate application development by eliminating the friction between development, QA, and production environments. This facilitates continuous development, integration and delivery in software development.
