Support Lifecycle for Clang/LLVM, Go, and Rust

Support Lifecycle for Clang/LLVM, Go, and Rust

On the heels of our recently announcement, General Availability of Clang/LLVM 6.0, Go 1.10, and Rust 1.29, I want to share how we’ll be supporting them going forward. Previously, these packages had been in “Technology Preview” status, which means that they were provided for “you to test functionality and provide feedback during the development process”, and were “not fully supported under Red Hat Subscription Level Agreements, may not be functionally complete, and are not intended for production use”.

So now that we’ve promoted them to fully supported status, what does that mean? In the simplest terms, General Availability (GA) means that these packages have officially entered the “Full Support Phase” of their lifecycle:

How to install Python 3 on Red Hat Enterprise Linux

How to install Python 3 on Red Hat Enterprise Linux

This article shows how to install Python 3, pip, venv, virtualenv, and pipenv on Red Hat Enterprise Linux 7. After following the steps in this article, you should be in a good position to follow many Python guides and tutorials using RHEL.  Note: For RHEL 8 installs, See Python on RHEL 8.

Using Python virtual environments is a best practice to isolate project-specific dependencies and create reproducible environments. Other tips and FAQs for working with Python and software collections on RHEL 7 are also covered.

There are a number of different ways to get Python 3 installed on RHEL. This article uses Red Hat Software Collections because these give you a current Python installation that is built and supported by Red Hat. During development, support might not seem that important to you. However, support is important to those who have to deploy and operate the applications you write. To understand why this is important, consider what happens when your application is in production and a critical security vulnerability in a core library (for example SSL/TLS) is discovered. This type of scenario is why many enterprises use Red Hat.

Python 3.6 is used in this article. It was the most recent, stable release when this was written. However, you should be able to use these instructions for any of the versions of Python in Red Hat Software Collections including 2.7, 3.4, 3.5, and future collections such as 3.7.

Expanding architectural choices to better arm Red Hat Enterprise Linux developers

Expanding architectural choices to better arm Red Hat Enterprise Linux developers

Red Hat Enterprise Linux continues to deliver the best possible experience for enterprise system administrators and developers, as well as provide a solid foundation for moving workloads into both public and private clouds. One of the ways to enable such ubiquity is Red Hat’s multi-architecture initiative, which focuses on bringing Red Hat’s software portfolio to different hardware architectures.

Last week, Red Hat Enterprise Linux 7.5 went live. It brought forward several improvements relevant to developers and system administrators such as advanced GUI system management via the Cockpit console, which should help new Linux administrators, developers, and Windows users to perform expert tasks without having to get into the command line.

This release also marks a new milestone for Red Hat Enterprise Linux: all supported architectures are now simultaneously enabled. The list of supported architectures includes x86_64, PowerPC Big Endian and Little Endian, s390x, and the more recently introduced 64-bit Arm and IBM POWER9 architectures.

Create a scalable REST API with Falcon and RHSCL

Create a scalable REST API with Falcon and RHSCL

APIs are critical to automation, integration and developing cloud-native applications, and it’s vital they can be scaled to meet the demands of your user-base. In this article, we’ll create a database-backed REST API based on the Python Falcon framework using Red Hat Software Collections (RHSCL), test how it performs, and scale-out in response to a growing user-base.

Flexible Images or Using S2I for Image Configuration

Flexible Images or Using S2I for Image Configuration

Container images usually come with pre-defined tools or services with minimal or limited possibilities of further configuration. This brought us into a way of thinking of how to provide images that contain reasonable default settings but are, at the same time, easy to extend. And to make it more fun, this would be possible to achieve both on a single Linux host and in an orchestrated OpenShift environment.

Source-to-image (S2I) has been introduced three years ago to allow developers to build containerized applications by simply providing source code as an input. So why couldn’t we use it to make configuration files as an input instead? We can, of course!
