Openshift vs Kubernetes: 9 Differences You Should Know

You could not use knowledge about one platform when working with another platform. Furthermore, the lack of awareness about OpenShift vs Kubernetes vs Docker is also responsible for the lack of clarity about the boundaries of the platforms. Even if they appear unrelated, you can learn to apply the functionalities of one in the other. The features of testability and reproducibility alongside isolation in Docker are superior to the guided approach in OpenShift.

Automated Data Processing

Kubernetes lends a supporting hand to Docker with the facility of containers. Kubernetes is the ideal instrument for coordinating many clusters of nodes at the production level. Enterprise applications don’t do very well with Docker and can involve various microservices. Based on the selected data management pattern, the microservices communicate with each other. Complex applications can require multiple containers, thereby leading to challenges for developers. However, Kubernetes is not a complete platform as a service (PaaS) and there are many considerations to keep in mind when building and managing Kubernetes clusters.

Community and Vendor Support

For example, OpenShift Origin is the opensource cloud-based platform of Red Hat used for building, testing, and deploying applications to the cloud. Both Kubernetes and OpenShift are excellent options for large-scale deployment of containerized applications. Docker EE is suitable mostly for orchestrating Docker images as it is tightly integrated with Docker API for intercommunication. But Kubernetes https://forexhero.info/ handles Docker images as well as independent containers and provides a wide set of features equal to all workloads. OpenShift support all workload types be it docker images as it enclosed with Kubernetes. Kubernetes helps simplify container runtime by managing Docker-based applications that are placed on an underlying assures system that maintains several replicas of running applications.

Integrated CI/CD with Jenkins

Atlassian Compass is an extensible developer experience platform that brings disconnected information about engineering output and team collaboration together in a central, searchable location. When comparing the two, a better comparison is of Kubernetes with Docker Swarm. Docker Swarm, or Docker swarm mode, is a container orchestration tool like Kubernetes, meaning it allows the management of multiple containers deployed across multiple docker vs kubernetes vs openshift hosts running the Docker server. Swarm mode is disabled by default and is something that needs to be setup and configured by a DevOps team. Red Hat OpenShift is an open-source platform for container application development, deployment, and management. OpenShift enables developers to build and deploy Docker-formatted containers on an integrated development environment (IDE), and then manage them with the Kubernetes platform.

  1. On the contrary, with an in-built image registry, OpenShift pairs seamlessly with DockerHub or Red Hat.
  2. Now that we have a basic understanding of what Kubernetes and OpenShift are, let’s delve into the key differences between these two platforms.
  3. Solomon Hykes founded Docker in 2008, when it was formerly known as DotCloud.
  4. First, create a config.json file that enables the configuration of the resulting disk.
  5. Docker Swarm is a container orchestration solution built into the Docker Community Edition.

Infrastructure abstraction

The additions in OpenShift provide a legible course of improvement over Kubernetes and can revise conventional notions of container orchestration. So, the possibility of an intertwined DevOps tools suite cannot be underscored here. While Docker is a container runtime, Kubernetes is a platform for running and managing containers from many container runtimes.

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. However, when you add Docker Swarm to the mix, Docker can be considered an alternative to OpenShift for small-scale use cases. Developed & introduced by RedHat, OpenShift is an open-source but paid container orchestration platform to assist enterprise-grade organizations in developing, deploying, and orchestrating containers. OpenShift is a Kubernetes derivative, incorporating Kubernetes components and additional RedHat utilities.

Kubernetes only makes services available when they are running and ready. Kubernetes bundles a set of containers into a group that it manages on the same machine to reduce network overhead and increase resource usage efficiency. An example of a container set is an app server, redis cache, and sql database. Upgrading is simple, as you only have to invoke the kubeadm upgrade command to get the recent version.

OpenShift lets users deploy applications from their source code repository, following DevOps best practices. OpenShift takes care of container management and orchestration in an efficient manner. As a part of Red Hat’s project, it has a mix of features of both Kubernetes and Docker to serve as a potent tool. In addition, this cloud-based solution provides automated installation and maintenance, allowing organizations to streamline application deployment and scaling, both on-premises and in the cloud. Beyond just observation, Komodor integrates with your existing CI/CD pipelines and configuration management tools to make routine tasks more seamless.

These systems fail fast, bugs show up in QAC, and typically don’t make it to production. They do this without red tape, since there’s a reliable process around deployment. Red Hat had created Openshift long before Kubernetes existed and was a PaaS from start. By implementing K8s, it became easier to bring more features and one of the most exciting is integrated, Jenkins. Even though there are plenty of CI/CD software solutions available, Jenkins is still the biggest, most universal, generic and mature solution.

They act as load balancers, distributing incoming requests across all available pods to maintain optimal performance and availability. This architecture allows closely related containers to share the same lifecycle—for example, an application container and its helper containers. When packaging containers in pods, they should  be as lightweight as possible, focusing on a single responsibility per container for modularity and scalability. The situation right now is a little more complicated than when the question was originally asked. Inside the container, OpenShift models units of functionality (web servers, dbs) via “cartridges”, which are a set of shell script hooks that are called when the system is invoked.
