Red Hat Enterprise Linux

Many developers would like to run their existing applications in a container with restricted capabilities to improve security. However, it may not be clear which capabilities the application uses because the code uses libraries or other code developed elsewhere. The developer could run the application in an unrestricted container that allows all syscalls and capabilities to be used to avoid possible hard to diagnose failures caused by the application's use of forbidden capabilities or syscalls. Of course, this eliminates the...

For businesses looking to build scalable Internet of Things (IoT) solutions using containers, here is a sample project built on the Red Hat OpenShift Container Platform . This project implements an intelligent IoT gateway on the OpenShift Container platform. The IoT Gateway is critical for enterprise IoT as it brings intelligence, and enables key services, at the edge. In this project, the gateway application is deployed as a set of microservices inside containers on OpenShift. A software sensor sends a...

(Probably, a more accurate title would be "The Evolution of a Linux Container Developer") Since .NET now runs on Linux (as well as Windows and macOS), the whole world of Linux containers and microservices has opened up to .NET developers. With a large pool of developers, a long track record of success, and performance numbers that are impressive, .NET offers a great opportunity to expand the world of Linux containers to formerly Windows-centric developers. While it’s tempting to rush in...

Follow this blog post, and within minutes you will have an ASP.NET MVC website running on Red Hat Enterprise Linux (RHEL). Yes, I'm talking to you, Windows .NET developer; you're about to double your OS skillset. Let's do this. I'm going to start with some assumptions: You are running Windows. You are not running Linux.

Tutorial: Using the OpenSCAP integration in ManageIQ In ManageIQ we have been working on leveraging OpenSCAP to show container images that infringe known vulnerabilities based on the latest CVE content distributed by Red Hat. Integrating...

Part 1 of 2 "Docker is about running random crap from the Internet as root on your host" - Dan Walsh Do you trust your containers? In container-based development flows, a developer will create an image to be the base for an application. Images are stateless, read only, and they are built in layers. These layers represent everything in an application's runtime environment but the kernel, which will be “borrowed” from the hosting machine. Such layers include distribution, packages, environment...

This is the first part of a 2 part article, part 2 (End To End Encryption With OpenShift Part 2: Re-encryption) will be authored by Matyas Danter, Sr Consultant with Red Hat, it will be published soon. This article aims to demonstrate use cases for Openshift routes to achieve end-to-end encryption. This is a desirable and sometimes mandated configuration for many verticals, which deal with strict regulations. For example, financial sectors often are extremely careful about their application security standards...
