Either way, this is how you respond.Ĭontainers provide an isolated environment for running the application. The question could either be differences between virtualization and containerization or differences between virtual machines and containers. Once you’ve explained containerization and virtualization, the next expected question would be differences. Difference between virtualization and containerization Most famous containerization environments are Docker and Kubernetes.Ĥ.
Now when you wish to run the application on another system, the container is deployed which will give a bug-free environment as all the dependencies and libraries are wrapped together. So basically, an application that is being developed and deployed is bundled and wrapped together with all its configuration files and dependencies. This problem was solved by the containerization concept.
#Interview questions on docker and kubernetes software#
Usually, in the software development process, code developed on one machine might not work perfectly fine on any other machine because of the dependencies. The virtual environment created by the hypervisor is called Virtual Machine. A software called Hypervisor makes this kind of splitting possible. Virtualization lets you split one system into many different sections which act like separate, distinct individual systems. These virtual versions or environments are created from a single physical hardware system. Virtualization is the process of creating a software-based, virtual version of something(compute storage, servers, application, etc.). Type 2: This kind of hypervisor makes use of the underlying host operating system.It has direct access to your host’s system hardware and hence does not require a base server operating system. It runs directly on the underlying host system. Type 1: It’s also called Native Hypervisor or Bare metal Hypervisor.You can basically have multiple OS on a single host system. It divides the host system and allocates the resources to each divided virtual environment. It is also called Virtual Machine Monitor. Let’s have a look at them.Ī hypervisor is a software that makes virtualization possible. An interviewer will start with these and eventually increase the difficulty level. This category of Docker Interview Questions consists of questions that you’re expected to know. I have categorized these 50 questions into: Go ahead and take advantage of all the new job openings with this article which lists down 50 most important Docker Interview Questions. Increasing demand for docker showed an exponential increase in job openings. Soon it turned out to be a big hit by the end of 2017 with 8 billion container image downloads.
Introduced in 2013, Docker hit the IT industry.
