What is docker and kubernetes?

Question

Hello! I'm doing few experiments and researches on DevOps these days and found the echo of docker and kubernetes everywhere. I want to know what are they actually and why are they so popular among developers.
To make the things more clearer I visited some blogs and tutorials telling about these techs, and they were talking about containers. What are they? How can they be helpful in my projects?
Thanks 😘😘

Answer 1

Docker — это проект, который использует открытый исходный код и распространяется под свободной лицензией. Docker — основан на работе контейнеров в системе Linux, а в качестве языка программирования для написания Docker использовался язык Go от компании Google.
Kubernetes — открытое программное обеспечение для автоматизации развёртывания, масштабирования контейнеризированных приложений и управления ими.

Docker is a project that uses open source code and is distributed under a free license. Docker - is based on the work of containers on the Linux system, and the Go language from Google was used as the programming language for writing Docker. Kubernetes is open source software for automating the deployment, scaling and management of containerized applications.
