Decoding the Container Orchestration Symphony: Navigating Docker, Containerd, and Advanced CLI Tools

Introduction: In the ever-evolving realm of containerization, discerning the nuances between Docker, Containerd, and their respective command-line tools is paramount. This blog endeavors to illuminate the journey of these technologies and offer insights into CLI tools such as ctr, nerd control, and cri control. The Container Era Genesis: As containerization dawned, Docker emerged as a beacon of user-friendly simplicity. Kubernetes later entered the stage, initially tailored to orchestrate Docker containers. The expanding container landscape prompted Kubernetes to embrace diverse runtimes, leading to the inception of the Container Runtime Interface (CRI). Docker and Kubernetes Integration: Initially, Kubernetes tightly embraced Docker, establishing it as the primary runtime.
