OpenShift vs Docker Top 10 Differences between OpenShift vs Docker

Docker Hub is a software-as-a-service tool that allows users to share containerized applications via a centralized library. It boasts over 100,000 publicly-available applications, in addition to private and public container registries. Docker Engine, which creates server-side daemons to host containers, images, storage volumes, and networks, is the core technology handling tasks and processes.

Docker hub uses the cloud to host and distribute your images and containers, promoting developers’ collaboration. Openshift is a Kubernetes platform developed by Redhat that provides a cloud environment when building application containers. It works as a platform-as-a-service that helps developers containerize their applications. It makes it easy to build, run and deploy applications with good experience.

At Red Hat, we want to make the experience simple when developers target Kubernetes as the runtime environment for their containerized applications. Together with Docker Inc, we have developed the OpenShift Extension for Docker Desktop. This extension allows developers to deploy their Docker containers on a free Developer Sandbox for Red Hat OpenShift environment . Or they can use any other OpenShift cluster of their choice that they can configure. Developers can do all of this without leaving the Docker Desktop UI. Containers only have access to resources defined in the image unless you give the container additional access when creating it.

While OpenShift offers a more sophisticated set of capabilities, specific development teams may find this platform too complicated to use, particularly startups and solitary developers. Also, RedHat OpenShift installation is more complicated, and not all container images from public registries may be utilized because of higher security rules. Red Hat designed OpenShift as an enterprise-grade, open-source container orchestration platform. To meet that grade, OpenShift packs additional security, productivity, and hybrid cloud features.

Understanding The Difference Between Kubernetes Vs. Openshift

Openshift is another popular Container management tool developed by RedHat. The, One of the popular flagship products of OpenShift is OpenShift Container Platform. So, This platform is an on-premises Platform as a Service built with Docker Container and the Kubernetes. Because applications develop over time, a single image name can actually refer to many different versions of the “same” image.

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. Both technologies have advantages and disadvantages, so the business may select the one that best meets its needs. Choose the best Docker kubernetes training to get complete detail. Its accessible Github repository has more stars and forks, rendering it much more prevalent among developers. Docker, on either hand, uses Docker images to do the same thing, and behind the doors, a lot of manual work is required.

Securing Container Images Across the CI/CD Pipeline

Red Hat offers OpenShift platform as a service that is mainly powered by Kubernetes and includes Docker to manage the variety of workloads. OpenShift is a solution by Red Hat built upon Kubernetes and Docker projects. For any glitches or support in implementation, Red Hat OpenShift offers a paid support.

Find out in this report how the two Container Management solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI. Containerization has simplified application development, administration, and distribution across diverse infrastructures for developer teams. Openshift and Docker are well-known openshift consulting containerization technologies,which offer sophisticated features. A pod is collection of containers and its storage inside a node of a Kubernetes cluster. It is possible to create a pod with multiple containers inside it. Following is an example of keeping a database container and web interface container in the same pod.


However, it limits deployment possibilities for organizations that do not use these platforms. Docker supports various desktop and cloud native environments for build, test, and deployment phases. Docker is a container engine for deploying a small number of containers in a development environment. Docker technology enables you to automate the deployment of applications in portable containers that run in the cloud or on-premises. Container orchestrators often use Docker to deploy containers at a larger scale. OpenShift is an enterprise platform for container orchestration, while Docker is just a container engine.

On the other hand, OpenShift does not require this and is incompatible with these systems as well. 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. Comparing just the runtime containers, OpenShift and Docker both use kernel isolation features to keep tenant processes separate. For Docker that is primarily through LXC and for OpenShift that is largely through SELinux and Multiple Category Security .

Exploring the Symbiotic Relationship: OpenShift vs Kubernetes vs Docker

OpenShift can be deployed across cloud and infrastructure borders and is utilized as a platform-as-a-service . OpenShift also reduces the operational complexity of managing self-managed Kubernetes clusters. Developers can make project resource requests via a web interface using the PaaS methodology, and CI/CD approaches and workflows significantly shorten delivery times.

  • Container management relies heavily on these technologies which make it simpler to execute and effectively deploy containers safely.
  • It enabled programmers to include all of the necessary libraries, configuration files, or dependencies in one package.
  • The latest versions of Docker’s root certificate authorities are merged with system defaults.
  • We have been receiving regular requests from our readers who are preparing for any of the Kubernetes, OpenShift, or Docker certifications about the difference between these three.
