What is difference between Docker and Kubernetes?
A fundamental difference between Kubernetes and Docker is that Kubernetes is meant to run across a cluster while Docker runs on a single node. Kubernetes is more extensive than Docker Swarm and is meant to coordinate clusters of nodes at scale in production in an efficient manner.
What are the types of Docker?
There are three common Docker network types bridge networks, used within a single host, overlay networks, for multi-host communication, and macvlan networks which are used to connect Docker containers directly to host network interfaces.
Which kernel is used in Docker?
Docker uses host OS kernel, there is no custom or additional kernel inside container. All containers which run on a machine are sharing this "host" kernel.
How many commands are there in docker?
At the moment, there are 13 management commands and 41 general commands. Here are the top Docker commands we are going to use for our lessons: docker attach - Attaches your local input/output/error stream to a running container. docker commit - Creates a new image from the current changed state of the container.Aug 3, 2018
What is docker Run command?

What is Docker and how it works?
Docker is an open source containerization platform. It enables developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.
What is docker in simple way?
In simple terms, Docker is a software platform that simplifies the process of building, running, managing and distributing applications. It does this by virtualizing the operating system of the computer on which it is installed and running. Docker is developed using the GO programming language.

Does Docker have a kernel?
The Docker technology uses the Linux kernel and features of the kernel, like Cgroups and namespaces, to segregate processes so they can run independently. Docker also automates deploying the application (or combined sets of processes that make up an app) inside this container environment.Jan 9, 2018
Does Docker run a Linux kernel?
The Docker technology uses the Linux kernel and features of the kernel, like Cgroups and namespaces, to segregate processes so they can run independently. Container tools, including Docker, provide an image-based deployment model.Jan 9, 2018
