The other features include sturdy container deployment, effective persistence in storage, and multi-cloud support. OpenShift also provides centralized policy management with a single console across various clusters to implement policies. However, the differences form crucial aspects of Kubernetes vs docker. Openshift positions itself more packaging platform which takes open source solutions and modifies them and ships them as a proprietary solution. Also, containerization presents credible benefits for the complete software infrastructure. Users can install docker on various nodes termed as Docker hosts. Docker Swarm emphasizes ease of use, making it most suitable for simple … Surrounding Kubernetes' explosive growth is an ecosystem of tools designed to simplify installing and managing Kubernetes clusters. The most prominent answer is that OpenShift depends on Docker and Kubernetes internally. Preparing to become a certified DevOps professional? While it’s common to compare Kubernetes with Docker, a more apt comparison is Kubernetes vs. Docker Swarm. or should we implement docker+openshift+kubernetes? The additions in OpenShift provide a legible course of improvement over Kubernetes and can revise conventional notions of container orchestration. Pros: Opensource and Big Community to support.

Continuing ahead with our discussion on OpenShift vs Kubernetes vs Docker, we shall also look at OpenShift vs docker. As applications in OpenShift v2 typically used multiple gears, applications on OpenShift v3 will expectedly use multiple containers. In terms of setup and installation, Kubernetes needs a series of manual steps for setting up Kubernetes master and worker nodes. Various Linux kernel features, including cgroups and namespaces, as well as configurable virtual environments. Traditional methods involved code development in a particular computing environment, and transfer of code development to a new environment resulted in errors and bugs. At CoreOS we considered Kubernetes to be the "kernel" of distributed systems. Kubernetes is less extensive and customizable whereas Docker Swarm is more comprehensive and highly customizable. The primary product of OpenShift is the OpenShift container platform that has Kubernetes in underlying architecture for container management.
