Kubernetes can also effortlessly scale its environment from one cloud to the next.
Most other orchestrators don't have this flexibility they're locked into specific runtimes or infrastructures.
Kubernetes, the first Cloud Native Cloud Foundation (CNCF) initiative and a Google foundation, is the fastest growing open source software project after Linux.
Kubernetes requires a number of manual interventions to configure its components such as etcd, flannel and docker engine. Kubernetes, Docker Swarm, and Apache Mesos are three common solutions/tools.ĭocker Swarm is the Docker native tool, which is very easy to set up and configure. Container lifecycle management can be accomplished with a variety of container orchestration solutions. It can assist you in deploying the same program across several environments without having to rewrite it.Ĭontainer orchestration technologies offer a framework for controlling containers and microservices architecture.
What is a Container?Ī container image is a ready-to-run software package that includes everything a program needs to execute, including the code and any run-times it needs, application and system libraries, and default values for any important settings.Īpplications are decoupled from the underlying host architecture using containers. VMs, on the other hand, enclose a whole operating system with executable code on top of an abstraction layer of physical hardware resources. Usually people compare Docker with Virtual Machines (VMs). To run several containers on the same OS, Docker leverages resource isolation in the OS kernel. Because of the isolation and security, you can operate multiple containers on a single host. What is Docker?ĭocker allows you to bundle and run an application in a container, which is a loosely isolated environment. Before getting started with Kubernetes, let's have a basic understanding of Docker and Containers.
