Docker is a powerful platform that enables developers and IT operations teams to build, package, and run applications in lightweight, portable containers.
These containers encapsulate everything an application needs to run—code, runtime, system tools, libraries—ensuring consistency across different environments, from a developer’s laptop to staging and production systems. Docker simplifies the development lifecycle, accelerates deployment, and enhances scalability, making it a cornerstone of modern DevOps practices and microservices architecture.
While many Kubernetes providers have shifted away from Docker as the underlying container runtime in favor of alternatives like containerd, Docker remains highly relevant today. It continues to be the go-to tool for building, testing, and managing container images. A solid understanding of Docker is still essential for anyone working with containers or Kubernetes, as the Docker CLI, Dockerfiles, and image management workflows are foundational to most modern container-based development pipelines.
