App development and deployment can help accelerate the pace of development. Containerization is a popular method of deploying these apps. Kubernetes and OpenShift are popular platforms for container management. There are many similarities between them, as OpenShift is Kubernetes. There are still some differences, which we’ll discuss in the article. OpenShift vs Kubernetes.
Kubernetes, an open-source software, automates deployment, management and scaling of containerized applications. OpenShift, on the other hand, allows for multi-tenant deployments and continuous development of applications. OpenShift adds developer and operation-centric tools to Kubernetes, making it possible to rapidly develop applications. These tools allow for easy scaling and deployment.
Top 10 Differences Between OpenShift & Kubernetes (i.e. OpenShift vs Kubernetes
There are many similarities between OpenShift, Kubernetes, as mentioned above. There are some differences between the two, but there are many similarities. Below are the top 10 differences between OpenShift & Kubernetes you should be aware of.
1. Product vs. project
One of the most important differences between OpenShift and Kubernetes is that one is a product and the other is a project. OpenShift is a well-known product, but Kubernetes can be described as a framework or open-source project. OpenShift allows users to install the product, which offers paid support with a subscription. CloudForms is included in the subscription, which further enhances the product’s features. Users must renew their subscriptions for their cluster. The amount increases with cluster expansion. An OpenShift tutorial will guide you through the OpenShift concepts.
Kubernetes is an open-source project that combines self-support with a variety of side projects, a community and a whole ecosystem. It provides support for users in difficult situations by external experts and the community. It is up to the users to decide whether they want to use the project or if they prefer to pay for the support and features. The Certified Kubernetes Administration certification is available to validate one’s skills as a Kubernetes administrator.
OpenShift and Kubernetes have different running environments. Kubernetes allows users to have greater control over the Operating System. OpenShift installation has its limitations. Red Hat Enterprise Linux Atomic Host and Red Hat Enterprise Linux (RHEL) are the two. Fedora and CentOS both allow OpenShift to be installed. Kubernetes does not require any special requirements regarding the operating system. Although Kubernetes deployment requires some skills and effort, it can be done with the latest cloud computing.
OpenShift templates are more flexible than Helm Charts of Kubernetes in terms of flexibility. It is difficult to deploy the OpenShift state-of-the art templates and packages for the Helm chart. Kubernetes can easily install the Automation Broker or Service Catalog available through OpenShift. Helm is not supported by OpenShift. This makes it difficult for users to use the rigid templates of the former.

OpenShift’s security policies are more stringent than those of Kubernetes. OpenShift prohibits the use of many container images, as well as official images. Although it is possible to run simple applications on Kubernetes using the OpenShift security policies, this is not allowed. OpenShift can provide a minimum level of security, but it requires certain permissions to do so. OpenShift makes it easy for users to learn how to deploy more apps.
Kubernetes can be distinguished from OpenShift by the areas of authorization and authentication. Kubernetes doesn’t have login commands but they do offer some authentications that are more difficult to set up and configure. OpenShift, on the other hand, offers integrated server for better authentication.
Both platforms offer authorisation through Role-Based Access Control. Kubernetes Security contexts are part of container specifications. OpenShift however has a separate Security Context Constraint. OpenShift’s approach to security is undoubtedly superior to Kubernetes.
4. Deployment Approach
OpenShift and Kubernetes have a different approach to deployment. Kubernetes has deployment objects, OpenShift uses DeploymentConfig. These deployment objects are
