Kubernetes vs OpenShift
Kubernetes and OpenShift are two popular options for Continuous Integration and Continuous Delivery (CI CD) among developers. While Kubernetes is an open-source platform for container orchestration, OpenShift provides an additional set of features including container orchestration, developer workflow, DevOps automation, and more.
In this blog post, we'll compare Kubernetes and OpenShift based on various parameters to help you choose the right platform for your CI CD needs.
Architecture
Kubernetes has a simple and modular architecture with a master node that manages multiple worker nodes. It provides a platform-agnostic approach to container orchestration and offers a wide range of options for customization.
OpenShift, on the other hand, is built on top of Kubernetes and provides several additional features such as integrated registry, CI CD pipeline, role-based access control (RBAC), and more. It also includes a web console for easier management of your containerized applications.
Ease of Use
Kubernetes is known for its steep learning curve, which can make it challenging for beginners. However, its simple architecture and extensive documentation make it easier to navigate.
OpenShift, on the other hand, provides a more user-friendly interface with a web console that simplifies the deployment of your application. It also includes several pre-built templates and example applications to make it easier for beginners to get started.
Scalability
Both Kubernetes and OpenShift are highly scalable and can handle large-scale containerized applications. However, OpenShift offers enhanced scalability through dynamic provisioning of resources, auto-scaling, and more.
Pricing
Kubernetes is open-source and free to use, but you may need to pay for additional support and management tools. OpenShift is a commercial product that provides additional features on top of Kubernetes and is available in different pricing plans based on your needs.
Community Support
Kubernetes has a large and active community of developers, which makes finding solutions and getting support easier. OpenShift also has a growing community but is relatively smaller than Kubernetes.
Conclusion
Both Kubernetes and OpenShift are solid options for CI CD needs. Kubernetes is a simple and flexible platform that requires additional tools for achieving CI CD workflows. OpenShift provides a comprehensive platform with additional features that make it easier for developers to deploy and manage containerized applications.
Ultimately, choosing between Kubernetes and OpenShift depends on your specific requirements, budget, and level of expertise. Consider your needs carefully and choose the platform that best suits your needs.
