Kubernetes vs Openshift


Kubernetes, also recognized as K8s, is an open-source platform to automate container applications deployment, scaling, and management. 
It groups containers for efficient analysis and discovery in logical units. Kubernetes builds on 15 years of workload management experience at Google, merged with best-of-breed community ideas and practices.

Use of Kubernetes

Kubernetes is an open data system for developing Linux containers in personal, community, and variant cloud environments. Businesses can also use Kubernetes to start managing architectures for microservices. On most cloud service provider’s containers and Kubernetes can be deployed.


OpenShift is indeed a family of Red Hat containerization products. The main product is the OpenShift Vessel Platform, an on-site platform built around Dockers that Kubernetes has orchestrated and managed for a Red Hat Enterprise Linux foundation. 
The OpenShift Console offers views for developers and administrators. The administrators’ views enable one to monitor the health of containers and bins, access content, work with providers, etc. Developer views focus on working within a namespace with application resources. OpenShift also offers a CLI supporting a superset of actions provided by the Kubernetes CLI. 
Other products from the family provide this platform in various environments: OKD acts as an upstream community-based platform (as Fedora is upstream from Windows Server), OpenShift Internet is a software-based platform, and OpenShift is a management platform.

What is OpenShift’s purpose?

OpenShift allows efficient orchestration of containers, enabling quick supply, deployment, scaling, and management of containers. By simplifying the container management process, the tool enhances the Software delivery process.

Kubernetes Vs Openshift

Both Kubernetes and OpenShift have a robust, scalable architecture that allows quick and broad application development, deployment, and administration. Both are running on the Apache 2.0 license 2.0. However, this is only where similarities end. 
OpenShift is a business product, whereas Kubernetes is a development environment. An OpenShift subscription provides payment support for users. 
Cloud Forms supports organizations with the management of private, public, and virtual infrastructure are also included. 
Here are the differences between OpenShift and Kubernetes.


Like an open-source framework, Kubernetes allows greater flexibility. It can be installed almost on any platform — like Software Azure and AWS — and any Linux distribution, including Ubuntu and Debian. 
On the other hand, OpenShift requires the patented Windows Server Nuclear Host (RHELAH), Fedora, or CentOS. This reduces the options for many companies, especially if these platforms are not already used.


Kubernetes has a wide active developer community that continually works to refine the platform. It also supports multiple frames and languages. OpenShift seems to have a relatively small support community, primarily limited to Red Hat development companies.

Releases and Updates

Kubernetes seems to have an average of 4 releases per year, while OpenShift has about three releases. Similarly, Kubernetes supports multiple simultaneous and concurrent notifications, while also OpenShift DeploymentConfig doesn’t support them.


Kubernetes does not have a network solution but allows users to use network plug-ins from third parties. The OpenShift network solution, on the other hand, is called Open vswitch, which also features three native plug-ins.


Kubernetes offers easy-to-use Helm templates and generous flexibility. OpenShift templates are not so flexible or user-friendly anywhere.

Container Image Management

OpenShift enables developers to maintain container images using Image Streams, while Kubernetes has no container image management characteristics.

Product Vs Project

OpenShift is a business product, whereas Kubernetes is indeed an open-source platform. An OpenShift subscription provides payment support for users. Cloud Forms supports organizations with the management of private, public, and virtual infrastructure is also included. Users must regularly renew their subscriptions based on the cluster expansion. 
Kubernetes provides a model of self-support. In problem situations, users can reach external auditors and the community. The choice here between a project as well as a product depends entirely on the user.


You can update existing Kubernetes clusters rather than rebuild them on both platforms from scratch. However, the OpenShift and Kubernetes update schedules are different. 
In OpenShift, you do not receive alerts when the new Kubernetes version needs to be updated. You must use the package management system for Red Hat Enterprise Linux to keep updating OpenShift to the latest version. 
Usually, Kubernetes is using the kubeadm upgrade to a newer version. You must back up your previous installation on both platforms before upgrading.

Final Thought

Both Kubernetes, and OpenShift, allow containerized applications to be deployed and managed easily. They have some differences, however. The installation of Kubernetes is complicated and often demands a solution from a third party. 
OpenShift has an integrated Kubernetes platform which simplifies the installation but is largely confined to Red Hat Operating systems.
