OpenShift is an enterprise platform for container orchestration, while Docker is just a container engine. However, docker vs kubernetes vs openshift when you add Docker Swarm to the mix, Docker can be considered an alternative to OpenShift for small-scale use cases. OpenShift is a PaaS that allows developers to deploy and scale applications easily through their platform which also makes use of container orchestration technology, Kubernetes, to manage Docker containers. The primary product of OpenShift is the OpenShift container platform that has Kubernetes in underlying architecture for container management. OpenShift involves a lot of cloud solutions, and it can be accounted for as a family of solutions. For example, OpenShift Origin is the opensource cloud-based platform of Red Hat used for building, testing, and deploying applications to the cloud.
OpenShift vs. Kubernetes: Key Differences Compared
Once you integrate the CI server, you can use commands to configure a manual CI/CD pipeline. If you’re starting to learn the differences between OpenShift vs Kubernetes, you need to learn a lot about the platforms. So, before we investigate the differences between the two platforms, let’s understand what they are, starting with Kubernetes. IBM offers both Kubernetes and OpenShift as distinct services with IBM Cloud. Moreover, though both are open-source programs, OpenShift is a paid platform service from Red Hat, while Kubernetes open-source code is a free service that can be downloaded from GitHub. Another case is managed Kubernetes, like EKS, CKE or Digital Ocean’s implementation.
Ultimately, OpenShift has a significant advantage over vanilla Kubernetes for both developers and IT operations. However, if your organization has the technical expertise to leverage Kubernetes’ flexibility and prefers an open-source solution, Kubernetes is the stronger choice. These built-in pipelines facilitate a seamless transition from development to production, enhancing productivity and reducing time-to-market. Kubernetes typically requires third-party tools for a comprehensive UI experience. While Kubernetes Dashboard offers a basic UI, more advanced functionalities often require integrating additional tools like Rancher or Lens to achieve a similar level of usability.
OpenShift, on the other hand, adds abstracted container cluster orchestration, management and some other features to form a whole software development and deployment solution. Kubernetes-based Kubernetes OpenShift platforms may be requested as a service in the public cloud with minimal infrastructure administration and excellent enterprise support. Companies may save operating costs while migrating to the cloud and still profit from the same tools and developer experiences they had on-premises, thanks to this cloud migration method. The OpenShift Container Platform is developed, managed, and administered by developers of Red Hat Inc., and comes with a paid subscription for administration and infrastructure management. On the other hand, the open-source version of OpenShift, also known as OKD, is a community edition platform that is restricted to ‘self-support’. As we have seen above, Kubernetes uses its basic features for effective container orchestration.
In contrast, Kubernetes requires external CLI tools and dashboards, which must be installed manually. The Kubernetes Dashboard is not included by default, and users must set up authentication, typically by creating bearer tokens. OpenShift simplifies this with its built-in login system and authentication handling, making it easier to manage user access and permissions. The Engine version of OpenShift is available in addition to the OpenShift container platform. In Docker Engine, the Docker Swarm mode supports load balancing of clusters.
Kubernetes Vs Docker: What Are the Differences?
An OpenShift template defines a collection of objects that can be processed and customised. These objects are then parameterised to create a list of deployable resources within the OpenShift Container Platform. Importantly, any resource that you are authorised to create within a project can be generated using a template. Namespaces in Kubernetes and Projects in OpenShift provide valuable ways to manage and allocate resources within a cluster.
- A lot of the Kubernetes features can also be integrated with ECS, however, you’ll have to combine quite a few AWS services like AWS Lambda to get the same features.
- Companies may save operating costs while migrating to the cloud and still profit from the same tools and developer experiences they had on-premises, thanks to this cloud migration method.
- Consider Docker + Kubernetes for larger projects with multiple containers and where you need high-availability and efficient scaling.
- The availability and usability of web-based UIs are important factors when choosing between Kubernetes and OpenShift.
- The manual nature of Kubernetes deployment also requires a deep understanding of its architecture and components, making it less accessible for beginners.
OKD is a sibling Kubernetes distribution to Red Hat OpenShift without the Enterprise-level support offered only by OpenShift. Despite OpenShift’s Kubernetes-based architecture, you can seamlessly work with Docker images. Also note while Red Hat OpenShift Container Platform is based on Kubernetes, it is compatible with Docker tools, like Registry, Builder, and Docker Hub. They are included in workload resources such as Deployments, DaemonSets, and Jobs.
- OpenShift has a much smaller support community that is limited primarily to Red Hat developers.
- Deploy and manage your containerized apps with ease by using IBM Kubernetes Service.
- Because of this, you may create, maintain, and deploy apps in various settings without encountering any problems.
- Engineers use it to deploy and manage clusters of hosts running Linux containers.

Looking to the future, containerization technologies are promising with topics such as Serverless computing, Orchestrated by AI, and improved Multi-cloud environments. By analyzing the differences between these clouds and identifying trends, firms can make decisions for their containerized applications. Kubernetes allows auto-scaling, load balancing and storage management features to containers. OpenShift powered with Kubernetes takes Kubernetes further and enables more simplicity in the management of workloads along with different types of tools.
Openshift Vs Kubernetes Vs Docker
Kubernetes offers Helm templates that are easy to use and provide a generous amount of flexibility. Learn the essentials of YAML and how it simplifies Kubernetes configuration. This guide covers the key structures and tips to write effective YAML files for managing your Kubernetes deployments. OpenShift’s platform may be a more attractive option for businesses seeking out-of-the-box automation and more compliance features. You might think of Kubernetes as the best option for DevOps to configure and customize application templates with more direct command-line controls. For deploymentconfig and many controllers — such as replication and namespace controllers — Kubernetes might be considered a more comprehensive option.
This console provides easy access, and many cluster management tasks can be performed using a straightforward form-based approach. It allows users to view and manage various resources, including servers, projects, and cluster roles. Kubernetes is an open-source Container-as-a-Service (CaaS) technology initially developed by Google and is now part of the Cloud Native Computing Foundation. It provides a portable containerisation solution, transforming application deployment, management, scaling, and networking.
Red Hat OpenShift
Complex applications can require multiple containers, thereby leading to challenges for developers. Kubernetes addresses the majority of operational concerns for application containers. Also, it is the largest open-source project in the world presently with prolific levels of community support. The other features include sturdy container deployment, effective persistence in storage, and multi-cloud support. Discover resources and tools to help you build, deliver, and manage cloud-native applications and services. Overall, OpenShift is a more complex platform than Docker, suited for those looking for a container orchestration tool that provides additional features over bare-bones Kubernetes.
Docker: Simplified Containerization
Two leaders have emerged in the sphere of container orchestration – Kubernetes and Red Hat OpenShift. The choice between OpenShift and Kubernetes for CI/CD depends on your organisation’s needs and preferences. Kubernetes is ideal if you require more customisation and are comfortable building your CI/CD pipeline from scratch. OpenShift, with its opinionated approach, is ideal for organisations looking for a more streamlined solution. It offers a fully integrated CI/CD setup, reducing the complexity of managing CI/CD workflows. The decision depends on the level of control and integration your organisation requires.
OpenShift is not directly comparable to Docker, because OpenShift is a container orchestration platform, while Docker is a container engine. However, in this article we’ll compare the orchestration features of OpenStack to those of Docker Swarm, which is included in the Docker Community Edition. Kubernetes has an extensive ecosystem with numerous plugins and third-party integrations. This flexibility allows organizations to tailor the platform to their needs, leveraging the vast array of tools and services in the Kubernetes community. Kubernetes supports multitenancy but requires additional setup and configuration to achieve the same level of isolation and resource management as OpenShift.
