OpenShift vs Kubernetes: The Seven Most Critical Differences

This includes the Kubernetes platform and Docker container images. It also includes additional features that are exclusive to the OpenShift enterprise platform. The biggest difference between Kubernetes and Docker is that while K8s is a container orchestration platform, Docker aims to be a complete containerization system. For example, Docker is a container engine with a container orchestration tool , and a dedicated image registry .

Developers can do all of this without leaving the Docker Desktop UI. We’re the world’s leading provider of enterprise open source solutions—including Linux, cloud, container, and Kubernetes. We deliver hardened solutions that make it easier for enterprises to work across platforms and environments, from the core datacenter to the network edge. OpenShift’s integrated server provides better authorization and authentication processes. You can manage and determine who gets access to specific aspects of your container or processes via the rules-based access control feature.


Community support – Numerous engineers and organizations contribute to the Kubernetes open-source project. Self healing – Through self-monitoring, recovery, and healing, Kubernetes restores or replaces containers that fail automatic health checks. Also, you might be reading this after learning Kubernetes no longer supports Docker in kubelets. So perhaps you are wondering which platform to use moving forward.

Our overview dives deep into their strengths and weaknesses as well as respective deployment scenarios. Hopefully, this article helped you understand the main differences between OpenShift and Kubernetes. When choosing a platform, you should consider your skillset and specs. The goal is to design the pipeline that works best for you, so be sure to experiment and check out the solution before adding the tool to your workflow. DeploymentConfig does not support multiple updates like Kubernetes objects. However, OpenShift DeploymentConfig has other advantages like versioning and triggers that drive automated deployments.

Containerization technology appeared on the scene and changed all that. It allowed developers to bundle the application code with all related libraries, configuration files, and dependencies. Comprehensive and capable CI/CD (Continuous Integration & Continuous Deployment) utilities are absent in Kubernetes, OpenShift, as well Dockers.

Docker and OpenShift are both well-known container management and orchestration platforms. They both have their unique features and advantages that make them suitable choices depending on your requirements. OpenShift’s built-in integration with Jenkins makes it a better, more efficient tool for building continuous integration and delivery pipelines. Both platforms offer a rich array of templates and automation tools to help make your development processes less strenuous and complicated.

Comparing OpenShift and Kubernetes

Resources and tools that help DevOps and IT professionals quickly create and maintain a distributed system. The ability to create applications using Docker Engine and Docker Datacenter remains with DevOps professionals. Premium service with constrained features and support for the entry-level package . Applications can be scaled by DevOps and IT staff by enabling clustering and adding new instances of the apps.

Docker has made a name for itself as an open source platform for creating, managing, deploying, and running applications. The program allows you to package and deploy applications easily on any given platform by separating the application from the environment. You can deploy applications in an Integrated Development Environment , and use Kubernetes to accurately manage them. With OpenShift’s self-service provisioning, your development teams can collaborate better to make ideas a reality.

Cloud Foundry is an open platform as a service that provides a choice of clouds, developer frameworks, and application services. Cloud Foundry makes it faster and easier to build, test, deploy, and scale applications. Both platforms offer authorization through role-based access control . The OpenShift approach outweighs that of Kubernetes in the security aspect. The security policies of OpenShift restrict you from running simple container images as well as many official images. OpenShift requires specific privileges to maintain a minimum security level.

This enables applications to function better, whether on-premises or in any developer ecosystem. Cluster container orchestration is a widely used form of container software technology and it is how Kubernetes is designed. OpenShift is not just an enterprise version of Kubernetes, it provides a lot of value add on top of that. Kubernetes itself isn’t really an end user product, it is just one project, which helps in managing containers. You need to add a bunch of other projects in with Kubernetes to make it more usable to developers.

  • OpenShift enables developers to build and deploy Docker-formatted containers on an integrated development environment , and then manage them with the Kubernetes platform.
  • And you need to look towards their community support for your queries.
  • Available in two different editions with Docker Enterprise edition offering enterprise-class support.
  • Default security procedures are incorporated into the layout of Docker containers.

Openshift is an abstraction layer on top of kubernetes and provides a useful UI that k8s lacks. As you may know, k8s is an orchestrator and requires your application packaged as an image. You can use docker to create your image though you are not limited and use other vendors like rocket etc for this purpose.

Also, as both of the technologies form an integral part of the cloud platform, they can be used independently. Kubernetes coordinates the resources allocated to it on your behalf. Kubernetes controllers ensure applications and containers run as specified. This frees your engineers to focus on writing and improving code — not the infrastructure beneath it.

Although it offers an additional degree of ownership and control over the storage and distribution of container images, Trusted Registry is a repository comparable to Hub. A SaaS tool called Docker Hub enables customers to exchange containerized apps through a centralized library. In addition to private and public container registries, it offers over 100,000 publicly accessible applications. CloudZero Dimensions organize your container spend into cost per customer, team, deployment, environment, project, software feature, and so on. Kubernetes and Docker do not provide comprehensive CI/CD tools out of the box. Yet Docker and K8s enable developers to automate their CI/CD pipelines, adding features such as load balancing and storage orchestration.

To achieve a consistent user experience, this can be deployed across cloud and infrastructure boundaries. The core K8s functionality is complemented by security and monitoring features and is based on centralised policy management. This ensures a high quality across the software landscape of an entire organisation. In contrast to previously ubiquitous but rather heavy virtual machines, containers are lightweight.

Support for developers and other personnel involved in the software development lifecycle to migrate apps to a cloud environment with the least amount of effort. Along with Docker and Kubernetes, Red Hat Enterprise Linux forms the foundation of the OpenShift platform. The administration of a project’s entire pipeline can be made easier with the help of OpenShift. Self-service provisioning for computing resources, container provisioning, and code pulls from version control systems are all possible. The Docker Swarm mode in Docker Engine allows load balancing of clusters. Users can quickly extend their container deployments to many hosts by doing this, which entails pooling together numerous Docker host resources so they function as one.

OpenShift vs. Kubernetes software: A comparative overview

So, the possibility of an intertwined DevOps tools suite cannot be underscored here. Therefore, OpenShift moves a step ahead in the battle of OpenShift vs Kubernetes with the feature to visualize applications in real-time. OpenShift also provides centralized policy management with a single console across various clusters to implement policies. The compatibility openshift vs docker aspect of OpenShift with Kubernetes is also a prominent factor in Kubernetes and OpenShift. The bundle of software or ‘container’ abstracts away from the host operating system, thereby implying its portability. Containers are very high in demand, currently with almost 61% of enterprise employees trying out their hands at containerization technology.

OpenShift vs Docker: Templates

With the help of container orchestration and management tools like Docker and OpenShift, companies can easily and seamlessly scale their apps. You can also create a more agile, swift, and secure code development process. Red Hat’s® OpenShift® is an open-source container platform that runs on the Red Hat enterprise Linux operating system and Kubernetes. The product is typically termed a “Platform as a Service” because it combines a host of services within the platform for enterprise businesses.

Who already receive the best AWS and cloud cost intelligence content. Experienced engineers often prefer Docker for development and Kubernetes for operations phases of their deployments. Both support various third-party tools, such as CircleCI and Jenkins, to create robust CI/CD pipelines in Kubernetes or Docker. Kubernetes’ inherent extensibility and horizontal scaling capabilities make it the most scalable compared to Docker.

“OpenShift vs. Docker – which is better for container virtualization? Kubernetes usually uses the kubeadm upgrade command to update to a newer version. On both platforms, you have to back up your existing installation before upgrading. You cannot implement DeploymentConfig with controllers; you have to use dedicated pod logics.
