Docker technology allows you to automate the deployment of applications in the form of self-sufficient, portable containers, which can run on-premises or in the cloud. The OpenShift platform is based on Red Hat Enterprise Linux (RHEL), as well as Docker and Kubernetes. OpenShift can facilitate the management of the overall pipeline for a project. You can implement self-service provisioning for computing resources, provision containers and pull code from the version control system.
- It allowed developers to bundle the application code with all related libraries, configuration files, and dependencies.
- Being a highly praised and recommended container technology, both OpenShift and Docker have garnered some prominent recognition.
- However, OpenShift templates are not as user-friendly or flexible as those offered by its rival, Docker.
- Trusted Registry is a repository similar to Hub, but it provides an added layer of ownership and control over the storage and distribution of container images.
- Simple words would say, docker is for creating, running, and managing a few containers, and Kubernetes is the magic trick.
Instead, It offers you to set up a Docker image registry (like Docker Hub) and entices images from Docker’s registry. Docker and OpenShift are both well-known container management and orchestration platforms. They both have their unique features and advantages that make them suitable choices depending on your requirements. Like Docker, OpenShift has strong security measures that help keep your containers and projects safe. You have to learn the platform’s security policies to sustain a minimum safety level and deploy more applications. A runtime container in OpenShift is used to create and deploy individual containers with REST, coordination, or web interfaces, whereas just runtime containers are utilized in Docker.
OpenShift Vs Kubernetes – Key Differences
Dockerhub is home to tons of Docker images from developers and verified companies. Ensure that the apps or services you want to integrate are compatible with your Kubernetes version and OpenShift cluster. You can also integrate a vast range of third-party plugins and tools at any point in your software development cycle. Simply find the plugin, app, or service that you want to integrate and follow the tool’s documentation to install and finalize the setup. The Pro plan costs $5/month when billed annually and $7/month when billed monthly.
Cluster container orchestration is a widely used form of container software technology and it is how Kubernetes is designed. To make your system apps portable, you need to link them with particular tools in the OpenShift deployment environment, including AWS CloudWatch and Azure Monitor. OpenShift has built-in monitoring and logging to streamline development and ensure smooth application deployment and operation. The Docker Swarm version of Docker Engine offers cluster load balancing.
When To Use Docker
OpenShift and Docker both have their own unique ways of orchestrating and managing containers, so there are no winners or losers here, only a matter of preference. Every facet of a container runs in its own namespace and its access is restricted to the namespace. Like its counterpart, it also employs groups to reduce the amount of input/output, CPU, and memory being consumed by your development processes. You can always consult OpenShift’s pricing page for up-to-date information and a detailed breakdown of service costs. In addition, Docker can be hosted on bare metals with a few custom configurations.
Kubernetes by itself is an open source software that automates deploying, managing, and scaling containers. 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.
Benefits of Docker
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. The most preferred management utility for most professionals is OpenShift’s ImageStream.
OpenShift is also a container platform like Docker with the credibility of Red Hat as its developer. Red Hat OpenShift 4 is the next generation of trusted enterprise Kubernetes platform. Kubernetes is very popular among large businesses, while Docker is the crowd favorite and is popular among organizations of different sizes. Interestingly, OpenShift is also making huge strides by gaining popularity as a container application platform powered by Kubernetes. If you’re aspiring to learn OpenShift, you can start with a quick OpenShift tutorial and get ahead. Along with awards, Docker has been a preferred container platform for many prominent IT firms.
Configuration and deployment
Sudip now works a full-time tech writer, focusing on Cloud, DevOps, SaaS, and Cybersecurity. When not writing or reading, he’s likely on the squash court or playing Chess. To deploy OpenShift, you’ll need RHEL, Red Hat CoreOS, or CentOS Linux distributions. Deployment is performed using the DeploymentConfig command, which cannot be implemented with controllers, rather can be used through dedicated pod logics.
The symbiotic relationship between these three tools leaves little for comparison. On the contrary, we should try out new ways of implementing them https://www.globalcloudteam.com/ in unison with each other. For example, Kubernetes can address various issues in Docker-only setup, and OpenShift could do the same for Kubernetes.
Differences between Docker vs Kubernetes vs OpenShift
I would start with the video and then look at kupernetes at a lower level. Once you are comfortable then start looking into the the features that openshift adds. OpenShift only runs on special operating systems from Red Hat, such as “Red Hat Enterprise Linux CoreOS” (RHCOS) and “Red Hat Enterprise Linux” (RHEL). Images openshift consulting created this way can be shared between developers and form the basis of standardized, reproducible developments. This inherent advantage of container virtualization led to the proliferation of distributed microservice architectures. This means that users receive dedicated support, with periodical upgrades.
What started as container virtualisation has evolved into a monolithic platform that performs too many functions at once. With Docker Swarm and Docker Compose, its use extends far beyond the original purpose. Compared to modern approaches, Docker is relatively weak in terms of security and performance. Kubernetes lacks built-in capabilities for authentication and authorization.
Cloud Volumes ONTAP
However, the process of transferring the apps they developed to a new environment was constantly plagued with bugs and errors. Red Hat OpenShift Container Platform comprises a number of core components, such as an authentication engine for APIs, a scheduler, a management platform and data storage. Trusted Registry is a repository similar to Hub, but it provides an added layer of ownership and control over the storage and distribution of container images. For new businesses, particularly for smaller enterprise businesses, OpenShift may be more attractive for its increased support, including easier deployment of CI/CD clusters. At their core, both Kubernetes and OpenShift can deploy and run on public cloud and local environments to enable a better end user experience.
