OpenShift vs Kubernetes : Product & Project Comparison



OpenShift can be described as a complete open-source container application platform. For container management and orchestration, Docker provides Docker EE. Due to its close integration with Docker API for communication, Docker EE is best suited for coordinating Docker images. Support for one-click application deployment, enabling users to deploy applications with a straightforward “Git push” command. 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. The first and most important distinction between OpenShift and Kubernetes is that OpenShift is a commercial product that requires a membership.

They are included in workload resources such as Deployments, DaemonSets, and Jobs. For each workload resource, the controller uses the PodTemplate within the workload object to create actual pods. This PodTemplate belongs to whatever workload resource your app runs on. Both Docker Swarm and Kubernetes support Role-Based Access Control . However, Docker Swarm nodes also implement TLS mutual encryption and authentication to protect what they communicate with each other. Deployment options include public, private, on-premises, and hybrid cloud setups for both.

  • The firm can choose either technology based on its benefits and drawbacks in accordance with its needs.
  • The control has multiple options like build, deploy, update, scale, expose, etc., which can be implemented with just a click of a button.
  • To meet that grade, OpenShift packs additional security, productivity, and hybrid cloud features.
  • It comes under the category of Virtual Machine Containers and Platforms in the tech stack.
  • In Kubernetes, kubectl, a powerful API and command-line tool, automates the bulk of container management tasks.

The default containers engine for OpenShift 4 is transitioning from Docker with CRI-O, which provides a small, simple runtime which moves in lockstep with Kubernetes. Almost everyone in the world uses both of these Docker vs red hat OpenShift technologies. A collection of tasks called Services specifies the status of either a container in a cluster. A single instance of the container is specified for each Service job, and Swarm distributes those instances across the nodes. It boosts productivity by making it easier to configure and deploy apps quickly.


The registry web console shows a token to be used for pull/push operations, but the token showed there is a session token, so it expires. Then, a user does not have to configure for token expiration, secret recreation, and other tasks, as the service account tokens will not expire. Coming to an end, if you are looking for maximum control over your containers, you should choose Kubernetes, but going this way will be a little tough as you’ll need in-depth knowledge. If you want to get the work done in an easier way without diving deep into technicalities and want good security and a user interface from where you can control your resources, OpenShift is the way. OpenShift comes with built-in support for CI/CD (Continuous Integration / Continuous Delivery/Deployment), which enables easier deployment of applications.

For example, imagine a user sent a request to what is now a dead container. Kubernetes can redirect this request to a healthy container, while it still fixes stuff in the background. The user reaches a healthy service so their request succeeds instead of failing.

We all know that we will have complex workflows to containerized applications in Kubernetes platforms. We need to build the container images, integrate with testing workflows, deploy to dev or production, then monitor and feedback the application lifecycle. Most of these operations are manual in Kubernetes or you need to deploy and integrate additional tools for such automated tasks. As well as the OpenShift container platform, the engine version of OpenShift is available. Both OpenShift and Kubernetes allow you to deploy and manage containerized applications quickly.

It pushes changes to the system in incremental steps, ensuring that every container has enough time to initialize smoothly. The platform can automatically add more resources when they’re needed , and remove resources when not needed . Moreover, horizontal scaling ensures that your existing infrastructure is not hampered while scaling up or down. With self-healing, Kubernetes can restart containers when they don’t pass health checks, and it can even terminate those containers once a restart threshold has passed.

Suppose your eCommerce website is going through a sale week, and suddenly the number of users requesting access increases. In this case, event-driven auto-scaling quickly launches new server instances to keep up with the increased demands. This strategy helps you not break down production servers while making newer deployments. The best part about this is Kubernetes can roll back the changes if there are any issues, so you can return to the stable version of your application. You can provide the cluster to Kubernetes and give the details of the resources required by each container that you want to deploy.

OKD is a distribution of Kubernetes optimized for continuous application development and multi-tenant deployment. Kubernetes and OpenShift are popular container management systems, and each has its own set of capabilities, advantages, and disadvantages. While K8s aids in the automation of application deployment, scaling, and operations, OpenShift is a containerization platform that works with Kubernetes to improve application performance.

With OpenShift Container Platform, a different set of steps must be performed, because the users can not run docker login commands on the host. Authenticated registries can be used to limit the images users can pull or who can access the external registries. OpenShift Kubernetes offers a service catalog that has two default service brokers. It also allows the users to integrate another service broker for the managed services as in the case in Kubernetes. The service catalogs of OpenShift allow the comfortable deployment of selective applications by the users. In the difference, the latter proves to be better in terms of the service catalog.

  • Also referred to as Origin, it supports multiple programming languages, including Go, Node.js, Ruby, Python, PHP, Perl, and Java.

Additionally, it offers a range of options for hardening Docker hosts to reduce the severity and risk of container breakouts. The attack surface is reduced by built-in security measures like control groups and kernel namespaces. You can choose your chosen languages and development environments by using the built-in support for Java, Ruby, Node.js, Python, PHP, and Perl while creating your applications. Ideally, to increase productivity, you want the flexibility to move your application between different cloud service providers without having to modify or replace your application infrastructure. In light of the above, when developers run into Kubernetes problems, they must wait for their questions to be answered, relying on the experience of other developers on discussion forums. Red Hat engineers are available to support OpenShift users around the clock.

docker vs kubernetes vs 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. In terms of setup and installation, Kubernetes needs a series of manual steps for setting up Kubernetes master and worker nodes.

Workload TypesAll workload types, including Docker images and Kubernetes-enclosed workloads, are supported by OpenShift. Technically challenging—to fully utilize OpenShift, you must have a working knowledge of both the technology and the market. DeploymentConfig, BuildConfig, Route, ImageStream, and ImageStreamTag objects are examples of resources that are exclusive to the OpenShift Container Platform that can be managed using oc command.

To do so, a free partition must be made available that contains an appropriate amount of free capacity. Both of these platforms are excellent, and it all boils down to your competencies and infrastructure requirements in the end. The web interface of OpenShift also provides a way to manage roles and servers with just a few clicks.

Anything you are authorized to produce within a project can be created using a template. Command line is not the only option that interacts with your Cluster, so does User Interface. Hence, an efficient web-based User Interface is necessary for cluster administration and cannot, therefore, be skipped when talking about Kubernetes vs OpenShift. Once you’ve set up your cluster, you need a way to interact with it. Hence, “Command line” is our next point of discussion in this OpenShift vs Kubernetes article.

Linux containers and virtual machines are packaged computing environments that combine various IT components and isolate them from the rest of the system. A Linux container is a set of processes isolated from the system, running from a distinct image that provides all the files necessary to support the processes. Spacelift is an alternative to using homegrown solutions on top of a generic CI.


From a small microservice or software process to a huge application, a single container can operate it all. All the necessary executables, binary code, libraries, and configuration files are contained within a container. Containers, in contrast to the server or machine virtualization, do not contain operating system images. As a result, they are more lightweight and portable, with less overhead.

Before switching between cloud services, you need to become familiar with the managed Kubernetes services in order to grasp how things work. True enough, the user experience and features of hosted or managed OpenShift remain the same. Docker provides a Docker Hub registry to share images with supported 3rd-party registries like Microsoft Azure Container Registry. Docker professionals can also leverage access to the latest Image Management Dashboard to share rich control and management over stored or shared images. OpenShift and Docker can be used hand in hand in a single customer application workflow.

Kubernetes Client and Server packages need manual upgrades on all systems. The ease of upgrading the Docker Engine makes it easily done in one-click. An observation of the popularity points for Kubernetes as well as docker mentioned above shows their effectiveness in application deployment.


This provides more space, application isolation, load balancing and consistently faster processing speeds. OpenShift, conversely, features an intuitive web console which includes a one-touch login page. The console offers a simple, form-based interface, allowing users to add, delete, and modify resources. Kubernetes doesn’t provide a complete out-of-the-box CI/CD solution. However, you can create an entire CI/CD pipeline by pairing Kubernetes with tools such as automated monitoring, testing, and CI servers. Also, third party plugins such as CircleCI can help you seamlessly build faster CI/CD pipelines in Kubernetes.


There will be multiple parts running inside each worker node that are nothing but a group of containers combined as a working unit. Kubernetes uses YAML to define the resources sent to the API server for creating the actual application. Comparing Kubernetes with OpenShift would not be fair as these container orchestration tools are two different projects. Kubernetes is an open-source project, while OpenShift is a product of Red Hat offerings. Comparing Kubernetes with OpenShift is like comparing an engine of a car with a car. This is because Kubernetes itself is the core part of the overall OpenShift architecture.
