Red Hat OpenShift vs Kubernetes: What's the difference?

Last but not least, we want to take advantage of the possibility to orchestrate our container clusters across infrastructure boundaries. At this point, the complexity of the system is no longer manageable for individuals. Special tools are needed which help organisations cope with this complexity. Comparing Kubernetes to OpenShift can be confusing because Kubernetes is a core component of OpenShift. While Kubernetes automates app deployment, scaling, and operations, OpenShift helps apps run more efficiently by integrating with Kubernetes. This article compares and contrasts the most important features of OpenShift with Kubernetes.

There is often confusion surrounding Kubernetes, Docker, and OpenShift, despite 90% of organizations using containers in production. By clicking “Post Your Answer”, you agree to our terms of service and acknowledge that you have read and understand our privacy policy and code of conduct. Connect and share knowledge within a single location that is structured and easy to search. Provide powerful and reliable service to your clients with a web hosting package from IONOS. Add to that the maintenance of the administrative system which will need to be monitored and updated. Furthermore, the security of the entire system must be guaranteed at all times.

How SELinux improves Red Hat Enterprise Linux security

OpenShift offers native routes that have already been configured for directing public traffic inside containers. This includes Fedora, Red Hat Enterprise Linux, CentOS, openshift consulting and Red Hat Atomic Host. In particular, Cloud Volumes ONTAP supports Kubernetes Persistent Volume provisioning and management requirements of containerized workloads.

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 (IDE), and use Kubernetes to accurately manage them. With OpenShift’s self-service provisioning, your development teams can collaborate better to make ideas a reality. OpenShift is compatible with container workloads that are built on different infrastructures.

Kubernetes Project vs OpenShift Product

First of all, the in-built security checks in the container stack across the application lifecycle provide constant security. The next important feature refers to in-built monitoring through a database and application monitoring software, Prometheus. You can also find Kubernetes as a promising instrument for monitoring container health and management of computing resources. The support of auto-scaling features and real-world use cases can simplify the applications of Kubernetes, thereby raising its popularity. Furthermore, the assurance of high availability in Kubernetes leads to its popularity.

A closer look at the features which make Kubernetes and Docker popular can be prominent comparison points in Kubernetes vs docker evaluations. So now, we should focus on observing the reasons for which Docker and Kubernetes are popular to support our discussion on OpenShift vs Kubernetes vs docker. Here’s an example of an actual repository in an image registry, where you can see that it contains a list of tags corresponding to different versions of the image.

Java runtimes and frameworks

Thus, you would need to create bearer tokens or another method of authentication manually, which is time-consuming and tedious. Docker Swarm does not provide automated https://www.globalcloudteam.com/ scaling based on resource utilization, unlike Kubernetes. In Docker, you execute commands and automation through a single API using a client-server architecture.

• Due to the fact that they are both open-source, OpenShift and Docker complement one another or can be utilized separately.
• Containerization is the most prominent trend in software and application development currently.
• Red Hat OpenShift 4 is the next generation of trusted enterprise Kubernetes platform.
• With Kubernetes and Docker CE, you need to download, install, set up, and oversee everything yourself, which requires skill and time.
• It is described as a platform for enterprise applications that require rapid innovation velocity.

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. 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.

Difference between OpenShift and Docker

You can build and deploy OpenShift container clusters in any environment with IBM Cloud Satellite. Businesses can also utilize Red Hat OpenShift tools and APIs with cloud options. IBM provides every form of compliance (e.g., SOC1, 2; GDPR; FIPS Level 4) and lets businesses access Jenkins as part of the OpenShift catalog as well as product expert support. Openshift is an enterprise solution by redhat that builds on kubernetes. Kubernetes is just a framework to help organize and automate working with docker containers.

For simple management and discovery, Kubernetes organizes containers into logical clusters. Kubernetes is capable of running in both cloud and on-premise systems, as well as hybrid clouds. OpenShift is a cloud development platform as a Service (PaaS) developed by Red Hat. Red Hat’s OpenShift is a PaaS (platform as a service) cloud development platform. It’s a user-friendly open-source cloud-based platform for developing, testing, and running applications before deploying them to the cloud. OpenShift allows developers to use an integrated development environment (IDE) to create and deploy Docker-formatted containers, which are then managed by the Kubernetes platform.

Red Hat OpenShift and Kubernetes technology

Traditional methods involved code development in a particular computing environment, and transfer of code development to a new environment resulted in errors and bugs. Containerization deals with this problem through bundling of the application code with configuration files, dependencies, and libraries for running it. Can this much info stand for the comparison between OpenShift, Kubernetes, and Docker? The following discussion aims to outline distinct comparisons between OpenShift, Docker, and Kubernetes. The individual comparisons can shed further light on the potential of each tool and the long-term prospects for their applications.

The three platforms support monitoring, but most cost tools do not provide detailed insights, such as cost per customer or cost per environment, only total and average costs. 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.

OpenShift vs Docker

As an example of when you might choose to use one, imagine you want to run your Python app in your OpenShift cluster. You could have a BuildConfig that knows how to build your image, by taking your source code from your Git repository, building it and layering it on top of a Python 3.8 base image. Then when it’s built, you want this new version to replace the running version in the cluster. Like a lot of (all?) kinds in Kubernetes, an ImageStream is an abstraction.
