Kubernetes Vs Docker Vs. OpenShift UPDATED 2023

The OpenShift platform prohibits running most container images, including many official images, which enhances security. It also requires a certain minimal level of privileges for most basic operations. Because it is based on Kubernetes, it also offers all the built-in security features in Kubernetes (as described below). Kubernetes is a portable containerization platform that provides a rich set of features designed to help manage services and workloads. Kubernetes comes with features that automate a range of tasks, including deployment, networking, and scaling. As well as the OpenShift container platform, the engine version of OpenShift is available.

  • Openshift uses an integrated container registry called ImageStreams to make image management easy, something which is not natively handled in Kubernetes.
  • A substantial change came with the recent introduction of OpenShift V3 (released October 2019).
  • It boosts productivity by making it easier to configure and deploy apps quickly.
  • It uses Tekton building blocks to automate deployments across multiple platforms by abstracting away the underlying implementation details.
  • The broad range of prefabricated container images is very practical.

The enterprise version comes with support from the Red Hat, and the open-source doesn’t. They both feature robust and scalable architecture that enables rapid and large-scale application development, deployment, and management. But that’s just about where the likeliness ends but not the analogy. I have tried to cover just a few out of many ways in OpenShift and Kubernetes differ. Plenty of Kubernetes experts will tell you, nothing in Open Source is free. Multiple people on the team need to learn some very complicated, inter-connected technologies that are written in new languages that they might have had no exposure to (GoLang in particular).

Does OpenShift support Docker images?

In short, containers contain code and the resources needed to run the code, while container orchestration is the automation of the management tasks of many containers (clusters). If you want to develop container images, Docker is your cup of tea. But for container orchestration, you can choose between OpenShift and Kubernetes based on your use cases, scalability, and budget, keeping in mind the integrated Jenkins support for CI in Dockins.

The machine executing the install has access to the mirror registry as well as the OpenShift API, but it does NOT have access to the internet in any form. All content must be shipped on a USB stick, optical media, or by other “offline” means. Agent Based Installation comprises a bootable ISO that contains the Assisted discovery agent and the Assisted Service. Agent-based installation is a subcommand of the OpenShift installer. It generates a bootable ISO image containing all of the assets required to deploy an OpenShift cluster, with an available OpenShift release image.

  • Utilize all the tools at your disposal, including blogs, YouTube, documentation, and any other online resources available to you.
  • You can use Terraform to manage all of your infrastructure which includes Kubernetes.
  • The openshift-install agent create image subcommand generates an ephemeral ISO based on the inputs you provide.
  • In short, containers contain code and the resources needed to run the code, while container orchestration is the automation of the management tasks of many containers (clusters).

In Kubernetes, the addition of virtual machines takes a lot of time. On the other hand, deployment in Kubernetes is complex and often performed only by an expert. You will have to set up every step of the pipeline for application deployment manually.

Infrastructure Support

Therefore, in the case of any issues or bugs, OpenShift offers a good paid support alternative for troubleshooting the issues. You can integrate the kubernetes with the Continuous Integration/Continuous Deployment (CI/CD) tools which will automate the deployment of the applications. With serverless computing and container technology being at the forefront, the demand for container technology has risen considerably. Container management platforms such as Kubernetes and OpenShift may be well-known, though possibly not as well understood. In this article, we will examine and point out some of the differences between two popular container orchestration management systems, Red Hat OpenShift and native Kubernetes.

OpenShift vs Kubernetes: Command line

Hence in the Kubernetes vs OpenShift, the former definitely has a fair advantage. Kubernetes technology is used by the reliable cloud-based Redhat OpenShift container platform. With the help of this platform, which is built on top of a Kubernetes cluster and makes use of its microservices-based design, you can create and release apps utilizing smaller, loosely linked components. OpenShift, a product of Red Hat, is a container management platform designed to support the development of applications.

So, This platform is an on-premises Platform as a Service built with Docker Container and the Kubernetes. It also does not provide built-in CI/CD integration but is easier to construct CI/CD pipelines as it offers Jenkins containers. It has support for Node.js, Python, Ruby, Perl, Go, and Java-based applications. You can also use Spacelift to mix and match Terraform, Pulumi, CloudFormation, and Kubernetes Stacks and have them talk to one another.

thoughts on “Docker Swarm vs Kubernetes vs OpenShift”

Depending on your platform, you must prepare the nodes (BareMetal or VM) for the control plane and compute nodes. Make sure all the nodes of the cluster are booting from the generated ISO image. First, docker vs kubernetes vs openshift let’s review each of the installation methods available for self-managed OpenShift clusters. Whether it is virtualized or bare metal, a cluster will have multiple virtual machines within it.

Kubernetes Features

These files are required later to configure the Mirror Registry for installation, and to direct Operators and Update Service to use the local registry. Before getting into the actual installation using the Agent Based Installer, let’s discuss the tools necessary to perform the disconnected installation. Exclusive cloud service use decreased over the past year, with hybrid models taking up the slack, demonstrating the shift in favor of the popularity of the latter option. Hybrid environments (cloud and local) are in use among some respondents. Docker was by far the favorite, with 64% of respondents opting for this choice.

Organizations that use OpenShift on AWS or Microsoft Azure also have the opportunity to use their committed spend on Red Hat products and services. 6 min read – Business today requires smart tools to manage ops and resources. Explore the types of enterprise resource planning (ERP) systems available. You might think of Kubernetes as the best option for DevOps to configure and customize application templates with more direct command-line controls. For deploymentconfig and many controllers — such as replication and namespace controllers — Kubernetes might be considered a more comprehensive option. On the whole, both Kubernetes and OpenShift provide a high-functioning continuous integration and continuous delivery (CI/CD) process.

What container orchestration services do you use in production?

Kubernetes is most commonly used with Docker but it can also be used with any container runtime. To better understand the differences between these services, let’s first look at the difference between containerization and container orchestration. It can be concluded that OpenShift features high-end security features, commercial customer support, user-friendly UI, and an option of the paid or commercial version. Being an open-source platform, OpenShift would not restrict you from sticking to the RedHat utilities as you can easily employ 3rd-party apps or utilities.

Consider Kubernetes if your infrastructure solely consists of containers and you have the resources to build and maintain your own container orchestration solution. 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.
