HOW DOCKER AND KUBERNETES WORK TOGETHER SOFTWARE

Create a container image from a Dockerfile.

HereвЂ™s what it takes to move a Docker container to a Kubernetes cluster. The containerized app instance running on the Kubernetes node derives the container runtime from the Kubernetes node along with compute, network, and storage resources, if needed.

A set of instructions for running the imageДЄ containerized application image along with a set of declarative instructions can be passed to Kubernetes to deploy an application.

The environment in which the image is executed.

A runtime instance of a Docker image consists of three parts: Docker provides a standard format for packaging and porting software, much like ISO containers define a standard for shipping freight.

HOW DOCKER AND KUBERNETES WORK TOGETHER SOFTWARE

Docker ContainersДЄ Docker container image is a lightweight, standalone, executable software package that includes everything needed to run an application: code, runtime, system tools, system libraries and settings. The Docker environment also includes a container runtime as well as build and image management. You can build, run and distribute applications in Docker containers to run on Linux, Windows, Macs and almost anywhere elseвЂ“both on-premises and in the cloud. Containers are isolated from each other and are designed to be easily portable.

What is Docker?Дocker is an open source container platform that uses OS-level virtualization to package your software in units called containers.

This guide provides an example of containerizing a simple application using Docker and deploying it on Kubernetes. Once you understand what containers and Kubernetes are, the next step is to learn how the two work together. Getting Started with Docker Containers on Kubernetes
