Understanding Red Hat OpenShift Container Platform

It’s fast, enables self-service provisioning, and integrates with a variety of 3rd party tools. Red Hat OpenShift provides users with an open-source Kubernetes environment that is developer focused to drive application development at the enterprise scale. But the storage element managed through Gluster can increase the complexity. OpenShift supports application development, deployment, and scaling, while also protecting the development infrastructure and providing a high level of security. Considering cyberattacks increased by 38% across the world in 2022, that’s a key benefit for many developers.

Let’s take a look at what the architecture of installing and working with OpenShift would look like. This blog looks at five major OpenShift benefits that you may not have heard about before. Kubernetes nodes can run on any Linux OS , while OpenShift nodes require Red Hat Enterprise Linux CoreOS.

Docker Images: Everything You Need to Know

The infra node, meaning infrastructure node, is used to host infrastructure services such as monitoring, logging, etc. So, in an OpenShift cluster, there must be a minimum of at least three control planes and a minimum of two worker nodes. Just like Kubernetes, Openshift platform orchestrates and manages containerized applications and can be used to easily scale up applications as required. Kubernetes and Openshift are the two most commonly used platforms for this purpose.

By integrating software bill of materials creation into the software development lifecycle, IT and DevOps teams can build more … Blockchain is most famous for its cryptocurrency applications, but data centers can employ it for a variety of business-related … OpenShift’s implementation of Deployment, called DeploymentConfig is logic-based in comparison to Kubernetes’ controller-based Deployment objects. As of v4.5, OpenShift is steering more towards Deployments by changing the default behavior of its CLI.

Cloud services editions

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. Kubernetes lacks a networking solution but lets users employ third-party network plug-ins. OpenShift, on the other hand, has its out-of-the-box networking solution called Open vSwitch, which comes with three native plug-ins.

The Ingress Operator is a component that implements the IngressController API and allows external access to the OpenShift Container Platform cluster service. All containers in a single pod share the same IP address and use the same data volume. Datastore—storing state and information related to the environment and applications.

Benefits of using OpenShift to manage Kubernetes

Solo.io, delivers application networking software that simplifies and unifies the configuration, operation and visibility of the network traffic within distributed applications. Kubernetes offers Helm templates that are easy to use and provide a generous amount of flexibility. OpenShift templates are nowhere near as flexible or user-friendly. Manually installing different agent types or collecting and correlating metrics is simply ineffective.

If you’re interested in a new career that offers security and excellent benefits, consider DevOps. Kubernetes has an average of four releases each year, while OpenShift trails with around three. Similarly, Kubernetes supports several concurrent and simultaneous updates, while OpenShift DeploymentConfig does not. 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.

How OpenShift differs from other container orchestration platforms

OpenShift’s client program, “oc”, offers a superset of the standard capabilities bundled in the mainline “kubectl” client program of Kubernetes. Using this client, one can directly interact with the build-related resources using https://globalcloudteam.com/ sub-commands (such as “new-build” or “start-build”). For the OpenShift platform, this provides capabilities equivalent to what Jenkins can do. For example, you may get a dashboard view that falls short in dynamic environments.

  • A Kubernetes cluster is made up of a single or a number of master machines called control planes and a single, or a set of worker machines called nodes.
  • You can run either platform on-premises or in the public cloud.
  • Because OpenShift is cloud-based, it works on any infrastructure, which is ideal for multi-platform development.
  • All the examples and code snippets used in this tutorial are tested and working code, which can be simply used in any OpenShift setup by changing the current defined names and variables.
  • While K8s helps automate application deployment, scaling, and operations, OpenShift is the containerization platform that runs with Kubernetes underneath to help applications run more efficiently.
  • This tutorial has been prepared for those who want to understand the features and functionalities of OpenShift and learn how it can help in building cloud-enabled services and applications.

Additionally, OpenShift includes a set of pre-created, easy-to-use templates that offer a simple click interface and can be easily customized to meet your needs. It also works with popular continuous integration tools such as Jenkins. Kubernetes and OpenShift are widespread container management systems, and each has its unique features, benefits, and undoubtedly some drawbacks too. While K8s helps automate application deployment, scaling, and operations, OpenShift is the containerization platform that runs with Kubernetes underneath to help applications run more efficiently. If you are already aware of containerization principles and have some idea about K8s, you would slightly lean towards Kubernetes since it is much more flexible than the OpenShift.

Kubernetes is an open-source container-as-a-service framework created by Google developers more than a decade ago. At its core, Kubernetes is a portable, open-source containerization system that lets developers manage services and workloads. The system automates application deployment, scaling, and operations.

Beginners should use the web interface rather than the command-line interface. The dashboard with K8s, on the other hand, isn’t ideal because it doesn’t add any more value to K8s than the command line. It totally depends on you what you chose, but I hope that this article has helped you in some way in selecting the best considering your needs and requirements. OpenShift supports various third-party integrations, including storage and infrastructure services, log analysis, monitoring, deployment, and diagnostic tools. You can use the Red Hat Marketplace and OpenShift catalog to install integrations on your cluster or use DIY open source software installations, Operators, or Helm charts. Kubernetes and OpenShift are both popular container management platforms with its unique features and advantages.

Implementing continuous integration and delivery (CI/CD)

This fine-grained control allows OpenShift 4 to scale from 10 to 10,000 containers. Red Hat’s self-managed offerings build upon each other to give you the flexibility to choose your level of control and security. OpenShift https://globalcloudteam.com/tech/openshift/ delivers a consistent experience across public cloud, on-premise, hybrid cloud, or edge architecture. The master node, which is also called the control plane, provides the basic services that manage the Open-shift cluster.
