They include Docker images, containers, volumes, networks, and other objects. Docker objects are elements necessary to construct the applications.The Docker client is a component that provides a command line interface (CLI) for interacting with Docker and instructing dockerd which commands to carry out.This continuous process manages Docker objects and communicates with other daemons. The Docker daemon (dockerd) is a service that runs on the host and listens to Docker API requests.
To understand how Docker works, you need to get acquainted with its main components and the role they play in the platform: Therefore, one server can host multiple containers, each running a different app.Īlthough containers are similar to virtual machines, they differ by an additional virtualization layer since they utilize the kernel and operating system of the host. As they virtualize resources of the underlying hardware, they are lightweight, flexible, and cost-effective.
#Docker and kubernetes difference software#
It has revolutionized and removed many tedious processes of software development and remains the leading container platform today.Ĭontainers provide an isolated environment for packaging apps. What is Docker?ĭocker is an open-source containerization platform used for creating, deploying, and managing applications in lightweight packages called containers. This will help you understand why there is no clear comparison between the two.
Read on to learn more about Docker and Kubernetes, their architecture, and what they are used. Learn more about how they differ in Kubernetes vs. Note: Based on the role they play, you can compare Kubernetes to Docker's official container orchestration tool - Docker Swarm.
