When should you use OpenShift vs Docker: pros and cons

If you want to develop container images, Docker is your cup of tea. Container technology works by bundling application code — along with its libraries and other necessary information — into a single event. It’s termed a “single unit” of application as it includes the most basic object or process-oriented code.

Though you’ll find certain CD pipeline features may better support your business needs. Openshift is more of an abstraction layer on container orchestration . Kubernetes is container orchestrating system for Docker containers which is more extensive as compared to Docker swarm . A DevOps setting that can support the entire deployment team, including developers and testers. Support for one-click application deployment, enabling users to deploy applications with a straightforward “Git push” command.

The prominent highlight in the world of container tools is the dominance of Kubernetes and Docker. An enterprise application platform with a unified set of tested services for bringing apps to market on your choice of infrastructure. Container orchestration automates the deployment, management, scaling, and networking of containers. The container management and orchestration solutions Docker and OpenShift are well-known. They both have distinct advantages and features that make them ideal selections based on your needs.

However, the differences form crucial aspects of Kubernetes vs docker. Let us take a look at the various points of differences between these two. 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.

Engineers use it to deploy and manage clusters of hosts running Linux containers. Kubernetes works on public, private, and hybrid clouds, as well as on-premises. Aqua Security is the largest pure-play cloud native security company, providing customers the freedom to innovate and accelerate their digital transformations. OpenShift is used to build distributed, scaling application and development environments using the Platform-as-a-Service model. The software provides a complete execution environment in which containers are deployed, executed, managed, and orchestrated.

Docker Engine, which creates server-side daemons to host containers, images, storage volumes, and networks, is the core technology handling tasks and processes. While Docker is merely a container engine, OpenShift is an enterprise platform for container orchestration. In reality, OpenShift deployments allow you to run Docker containers.

However, the update schedules of OpenShift and Kubernetes are different. Web-based User Interface is important for effective cluster administration. You have to install the Kubernetes dashboard separately and use the kube-proxy to forward a port of your local machine to the cluster’s admin server. In addition, you have to manually create a bearer token to provide authorization and authentication, since the dashboard does not have a login page. Docker’s biggest drawbacks stem from its organic growth over the years. What started as container virtualisation has evolved into a monolithic platform that performs too many functions at once.

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. Images created this way can be shared between developers and form the basis of standardized, reproducible developments. Docker is an open-source technology that can be used to package applications in containers or run application containers. Docker is used to create portable, self-contained application containers that can be executed in a cloud environment or on local computing hardware. In addition to the free open-source version, the company offers various paid products.

The platform uses Kubernetes for orchestration and builds on Docker capabilities, offering abstracted cluster orchestration and management tools. Docker is a clear leader when it comes to container-based virtualisation providing a basic technology for creating and running application containers. Docker is used predominantly by developers to standardise development workflows. OpenShift sits at the other end of the virtualisation spectrum, covering the operational needs of an entire organisation. NetApp Cloud Volumes ONTAP, the leading enterprise-grade storage management solution, delivers secure, proven storage management services on AWS, Azure and Google Cloud. In Docker Engine, the Docker Swarm mode supports load balancing of clusters.

  • Built-in encryption for application configuration data, platform secrets, and secure-by-default option.
  • The exact processes may vary, but they are both very reliable when it comes to keeping your data and projects safe.
  • With its fancy, modern interface, developers will find OpenShift to be an uncomplicated software that’s easy to navigate.
  • The platform keeps enterprise-grade security and extensive multi-tenancy features while enabling developers to optimize procedures while creating applications.
  • Also, you might be reading this after learning Kubernetes no longer supports Docker in kubelets.
  • Images created this way can be shared between developers and form the basis of standardised, reproducible developments.

The hosts can either be bare-metal servers or other virtual machines. Some of the notable features which make OpenShift a popular go-to alternative for containerization can help this discussion. First of all, the in-built security checks in the container stack across the application lifecycle provide constant security.

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.

This way, OpenShift will handle the burden of maintaining your clusters for you. OpenShift is designed to handle different kinds of apps and technologies based on your specific needs and capabilities. This means that you can develop multiple applications that run the same way across all your infrastructures from design to testing, staging, and production. So irrespective of where your pipeline workflow is housed—whether locally or in the cloud—you’re good to go.


Containerization uses clusters of nodes that function like one robust server. This provides more space, application isolation, load balancing and consistently faster processing speeds. It’s also helpful to have a basic knowledge of how container orchestration technology developed and where it stands today.

OpenShift vs Docker: Container

Before proceeding ahead on the comparison of OpenShift vs Kubernetes vs Docker, let us know more about containerization. Containerization is the most prominent trend in software and application development currently. It is generally assumed as a supporting element or alternative for virtualization. Containerization involves the packaging of software code and all related dependencies for running uniformly without any issues on any infrastructure. Also, RedHat OpenShift installation is more complicated, and not all container images from public registries may be utilized because of higher security rules.

There is often confusion surrounding Kubernetes, Docker, and OpenShift, despite 90% of organizations using containers in production. Yet to build and maintain containerized apps in optimal health, you’ll need a robust system. Docker Desktop is GUI application; various web interfaces are available for installation. The underlying open-source components are developed as part of the “Moby” project. In addition to the enterprise versions offered by Red Hat, OKD is a freely available community edition.

Alternatively, you can use Docker Hub to find and distribute container images with members of your team or the larger Docker community. It’s a cloud-based collaboration service for app development and registry. The container orchestration tool can help streamline your application development workflow to ensure the speedy delivery of your projects. Docker’s portable and lightweight program makes scaling applications and managing workloads a breeze. OpenShift is an enterprise-level Kubernetes container orchestration platform provided by the open-source software company, Red Hat. You can build and deploy OpenShift container clusters in any environment with IBM Cloud Satellite.

Local development environments are encapsulated as containers together with the tools and workflows in use. Images created this way can be shared between developers and form the basis of standardised, reproducible developments.
