Home Official Red Hat OpenShift Documentation

Red Hat has worked with hundreds of partners to validate technology integrations with Red Hat OpenShift, so organizations can make the most of their existing investments. API Server − It is an API server which provides all the operation on cluster using the API. API server implements an interface which means different tools and libraries can readily communicate with it. A kubeconfig is a package along with the server side tools that can be used for communication. 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.

A container is the runtime of an Open Container Initiative -compliant image. A node capacity is related to memory and CPU capabilities of the underlying resources whether they are cloud, hardware, or virtualized. Delivers the foundational, security-focused capabilities of enterprise Kubernetes on Red Hat Enterprise Linux CoreOS to run containers in hybrid cloud environments. It came from Red Hat’s acquisition of Makara, a company marketing a platform as a service based on Linux containers, in November 2010. OpenShift was announced in May 2011 as proprietary technology and did not become open-source until May of 2012. Up until v3, the container technology and container orchestration technology used custom developed technologies.

Red Hat OpenShift Service Mesh

It is designed to run on a local computer to simplify setup and testing and emulate the cloud development. The Developer Sandbox for OpenShift provides developers with a private OpenShift environment in a shared, multi-tenant OpenShift cluster that is pre-configured with a set of developer tools. OpenShift Web Terminal brings command-line tools right to the web console and its Linux environment runs a pod deployed on your OpenShift Cluster.

For example, a front-end web service connects to a database instance by communicating with its service. Services allow for simple internal load balancing https://www.globalcloudteam.com/ across application components. OpenShift Container Platform automatically injects service information into running containers for ease of discovery.

Edge computing

With a Red Hat subscription, you can deploy your application into a production environment and get world-class expertise and knowledge about security, stability, and maintenance for your systems. Our subscriptions provide many benefits including access to resources, expertise, upgrades, and the ability to directly influence our commitment to providing an exceptional customer experience. It is the central vehicle for managing access to resources for regular users. A project lets a community of users organize and manage their content in isolation from other communities.

Use containers and microservices to decompose legacy apps into portable workloads. Offload tedious and repetitive tasks around security, compliance, deployment and on-going lifecycle management to Red Hat OpenShift on IBM Cloud. Customers can accelerate application development by leveraging OpenShift APIs and tools for deployments on AWS.

OpenShift on IBM Cloud

A fully supported sandbox in which to rapidly develop, train, and test machine learning models. Red Hat OpenShift Serverless extends Kubernetes in order to deploy and manage serverless workloads. Controller Manager – It can be considered as a daemon which runs in a non-terminating loop and is responsible for collecting and sending information to API server. It works towards getting the shared state of the cluster and then make changes to bring the current status of the server to a desired state.

• OpenShift Container Platform supports multiple types of storage, both for on-premise and cloud providers.
• The web terminal eliminates the need to install software, configure connections, and authenticate your local terminal.
• The kubelet is responsible for registering the node with the cluster and receiving the details of container workloads.
• Developer-friendly workflows, including built-in CI/CD pipelines and source-to-image capability, enable you to go straight from application code to container.
• Red Hat OpenShift Virtualization lets you run and manage virtual machine workloads alongside container workloads.

OpenShift Platform Plus brings together everything you need for a DevSecOps approach to manage multiple clusters in a hybrid cloud environment. The container image registry and OperatorHub provide Red Hat certified products and community built softwares for providing various application services within the cluster. You can manage applications within the cluster either manually by configuring deployments of containers running from pre-built images or through resources known as Operators. You can build custom images from pre-build images and source code, and store these custom images locally in an internal, private or public registry. Red Hat OpenShift Kubernetes Engine delivers the foundational, security-focused capabilities of enterprise Kubernetes on Red Hat Enterprise Linux CoreOS to run containers in hybrid cloud environments. OpenShift Kubernetes Engine and OpenShift Container Platform are built on the same enterprise Kubernetes core platform and contain key Linux, container runtime, networking, management, and security capabilities.

Red Hat OpenShift vs. Kubernetes

Together, they offer an integrated approach to DevOps that incorporates tools for development teams to create and deploy microservices-based applications. The latest version of OpenShift Online provides a container-based platform that developers can access from any web browser, IDE and command-line interface. Dockerfiles are run without many of the normal operational controls of containers, usually running as root and having access to the container network. S2I can be used to control what permissions and privileges are available to the builder image since the build is launched in a single container. In concert with platforms like Red Hat OpenShift, S2I can enable admins to tightly control what privileges developers have at build time. Red Hat OpenShift is focused on security needs and makes deploying and managing container platforms easier.

With OpenShift Pipelines developers are free to choose tools such as Source-to-Image , Buildah, Buildpacks, and Kaniko, making application deployment portable across any Kubernetes platform. Red Hat OpenShift Virtualization lets you run and manage virtual machine workloads alongside container workloads. https://www.globalcloudteam.com/tech/openshift/ OpenShift Virtualization combines two technologies into a single management platform. This way, organizations can take advantage of the simplicity and speed of containers and Kubernetes, while still benefiting from the applications and services that have been architected for virtual machines.

Learn the foundations of OpenShift through hands-on experience deploying and working with applications, using a no-cost OpenShift cluster through the Developer Sandbox for Red Hat OpenShift. You want to deliver customer experiences on time, but you must consider security at every stage. Red Hat® OpenShift® 4 is powered by Kubernetes Operators and Red Hat’s commitment to full-stack security, so you can develop and scale big ideas for the enterprise. The OpenShift Container Platform installation program offers you flexibility. You can use the installation program to deploy a cluster on infrastructure that the installation program provisions and the cluster maintains or deploy a cluster on infrastructure that you prepare and maintain. OpenShift Container Platform utilises a number of computing resources, known as nodes.

Developer views are oriented around working with application resources within a namespace. OpenShift also provides a CLI that supports a superset of the actions that the Kubernetes CLI provides. OpenShift Data Foundation provides accessible data and support for all Red Hat OpenShift apps. Developers can provision storage directly from Red Hat OpenShift without switching to a separate user interface.

FORTIFY_SOURCE improves code security

With IBM Cloud Satellite, extend these workloads into on-prem, edge, or multi-cloud environments. In each Satellite “location,” managed OpenShift clusters ensure high availability through CI/CD, and real-time data through eventing. Developers describe Docker as “Enterprise Container Platform for High-Velocity Innovation”. The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere. On the other hand, OpenShift is detailed as “Red Hat’s free Platform as a Service for hosting Java, PHP, Ruby, Python, Node.js, and Perl apps”.
