From notebooks to pipelines: Using Open Data Hub and Kubeflow on OpenShift

By Juana Nakfour July 29, 2020July 27, 2020

Data scientists often use notebooks to explore data and create and experiment with models. At the end of this exploratory phase is the product-delivery phase, which is basically getting the final model to production. Serving a model in production is not a one-step final process, however. It is a continuous phase of training, development, and data monitoring that is best captured or automated using pipelines. This brings us to a dilemma: How do you move code from notebooks to containers orchestrated in a pipeline, and schedule the pipeline to run after specific triggers like time of day, new batch data, and monitoring metrics?

Advanced Helm support in the OpenShift 4.5 web console

By Serena Chechile Nichols July 20, 2020July 24, 2020

Helm is a popular package manager for Kubernetes that is fully supported on Red Hat OpenShift. Starting with OpenShift 4.5, we’ve made working with Helm charts in the OpenShift web console more intuitive than ever. In this article, we introduce the new features for accessing and managing Helm charts.

What enterprise developers need to know about security and compliance

By Daniel Domkowski and jlien June 23, 2020June 24, 2020

One of the luxuries of my job is that I get to speak to and work with a range of IT people employed by U.S. federal and state government agencies. That range includes DevOps engineers, developers, sysadmins, database administrators, and security professionals. Everyone I talk to, even security professionals, says that IT security and compliance can be imprecise, subjective, overwhelming, and variable—especially in the federal government.

Enterprise Kubernetes development with odo: The CLI tool for developers

By Jason Dudash June 16, 2020June 25, 2020

Kubernetes conversations rarely center the developer’s perspective. As a result, doing our job in a k8s cluster often requires building complicated YAML resource files, writing custom shell scripts, and understanding the countless options that are available in kubectl and docker commands. On top of all of that, we have the learning curve of understanding Kubernetes terminology and using it the way that operations teams do.

An easier way to create custom Jenkins containers

By Jay Flowers June 4, 2020June 25, 2020

In many organizations, it is a struggle for developers to get custom Jenkins container images created. Fortunately, in engineering, there is often more than one way to get the job done. In this article, I show you how to create your own custom Jenkins container image by aggregating readily available containers in a pod template.

Open Data Hub 0.6.1: Bug fix release to smooth out redesign regressions

By Václav Pavlín June 2, 2020June 25, 2020

It is just a few short weeks since we released Open Data Hub (ODH) 0.6.0, bringing many changes to the underlying architecture and some new features. We found a few issues in this new version with the Kubeflow Operator and a few regressions that came in with the new JupyterHub updates. To make sure your experience with ODH 0.6 does not suffer because we wanted to release early, we offer a new (mostly) bugfix release: Open Data Hub 0.6.1.

How the fabric8 Maven plug-in deploys Java applications to OpenShift

By Kevin Boone June 2, 2020June 25, 2020

The fabric8 Maven plug-in, often abbreviated FMP, can be added to a Maven Java project and takes care of the administrative tasks involved in deploying the application to a Red Hat OpenShift cluster. These tasks include:

Creating an OpenShift build configuration (BC).
Coordinating the source-to-image (S2I) process to create a container image from the application’s compiled bytecode.
Creating and instantiating a deployment configuration (DC) from information in the project.
Defining and instantiating OpenShift services and routes.

All of the relevant components of this process are well-documented individually. This article pulls together documentation sources to create an overview of how the plug-in works, and the structure of the image it generates—which might make the plug-in easier to use and troubleshoot.

Getting started with the fabric8 Kubernetes Java client

By Rohan Kumar May 20, 2020July 17, 2020

Fabric8 has been available as a Java client for Kubernetes since 2015, and today is one of the most popular client libraries for Kubernetes. (The most popular is client-go, which is the client library for the Go programming language on Kubernetes.) In recent years, fabric8 has evolved from a Java client for the Kubernetes REST API to a full-fledged alternative to the kubectl command-line tool for Java-based development.

Deploy and bind enterprise-grade microservices with Kubernetes Operators

By Arthur De Magalhaes May 18, 2020June 26, 2020

Deploying enterprise-grade runtime components into Kubernetes can be daunting. You might wonder:

How do I fetch a certificate for my app?
What’s the syntax for autoscaling resources with the Horizontal Pod Autoscaler?
How do I link my container with a database and with a Kafka cluster?
Are my metrics going to Prometheus?
Also, how do I scale to zero with Knative?

Operators can help with all of those needs and more. In this article, I introduce three Operators—Runtime Component Operator, Service Binding Operator, and Open Liberty Operator—that work together to help you deploy containers like a pro.
