Support lifecycle for Clang/LLVM, Go, and Rust in Red Hat Enterprise Linux 8

Red Hat Enterprise Linux (RHEL) 8.1.0 includes updates to our llvm-toolset, go-toolset, and rust-toolset application streams, which provide developers with up-to-date versions of these compiler toolchains. The upstream projects for these streams move very quickly with new feature releases every six months for LLVM and Go, and every six weeks (!) for Rust. The communities around these toolchains encourage users to users to always stay up-to-date with the latest releases, which is why we try to get new versions into Red Hat Enterprise Linux as quickly as we can.

From a support perspective, we will continue to support these application streams for the entire life of RHEL 8. We will provide new features and bug fixes within the stream by updating to newer upstream releases on a regular basis. For llvm-toolset and go-toolset, you can expect stream updates every six months, and for rust-toolset you can expect updates every three months.

Changes to CentOS: What CentOS Stream means for developers

Changes to CentOS: What CentOS Stream means for developers

Today Chris Wright, vice president and CTO at Red Hat, published a post describing how CentOS is changing and the opportunities it opens for developers in the Red Hat Enterprise Linux (RHEL) ecosystem. The net effect of this change is that, in addition to CentOS Linux 8, there is a new version of CentOS—CentOS Stream—which will provide a “rolling preview” of future Red Hat Enterprise Linux kernels and features. This is being announced in addition to the release of the traditional CentOS Linux 8, which is a downstream rebuild of the current RHEL release.

In my previous article, Run Red Hat Enterprise Linux 8 in a container on RHEL 7, I showed how to start developing with the latest versions of languages, databases, and web servers available with Red Hat Enterprise Linux 8 even if you are still running RHEL 7. In this article, I’ll build on that base to show how to get started with Django 2 using the current RHEL 8 application stream versions of Python 3 and PostgreSQL 10.

You can start developing with the latest versions of languages, databases, and web servers available with Red Hat Enterprise Linux 8 even if you are still running RHEL 7. It is pretty simple to do with containers, even if you’ve only been through a “Hello, World” or two.

By the end of this article, you’ll have the current RHEL 8 application stream versions of PHP, MariaDB, and Apache HTTPD running in containers, managed by systemd on your RHEL 7 system. Podman makes it easy to accomplish this since there is no container daemon to complicate things. We’ll use WordPress as a placeholder for your own application code.

In May, we announced the general availability of Red Hat Enterprise Linux (RHEL) 8, the intelligent operating system which we believe is the best RHEL ever for developers. 

The work on Red Hat Enterprise Linux 8 continues, and we are pleased to announce the beta availability of RHEL 8.1., which enables greater developer productivity, improves manageability, and adds new security enhancements. This release also includes updated drivers that deliver new features and bug fixes for supported hardware platforms.

Have you tried Red Hat Enterprise Linux 8 (RHEL8) yet? Read on to learn how to quickly set up a LAMP stack on RHEL8 so you can play around with the new features built into the operating system.

A LAMP stack is made up of four main components and some glue. The first main component in a LAMP stack (the “L”) is Linux. In my example, I’m using Red Hat Enterprise Linux 8 for that, which gives me a secure operating system, a modern programming environment, and a user-friendly set of tools to control it.

Container-related content you might have missed at Red Hat Summit

Container-related content you might have missed at Red Hat Summit

If you weren’t lucky enough to attend the recent Red Hat Summit or you went but couldn’t make it to all the container-related sessions, worry not. We teamed up with Scott McCarty, Principal Technology Product Manager–Containers at Red Hat, to bring you an overview of what you missed.

Choosing the right container base image for your applications

The Red Hat Universal Base Image (UBI) gives you three options for building containers with the full power of Red Hat Enterprise Linux (RHEL) underneath. The goal is to create the smallest possible image that fully supports your application. You select a base image depending on the application you’re packaging in a container. For example, if you have a Golang or .NET application, all of that application’s dependencies are built in. That means you can use the minimal image (ubi-minimal), which contains microdnf, a package manager that only supports install, update, and remove functions. It also includes, well, a minimal set of tools.

Red Hat Enterprise Linux 8 Image Builder: Building custom system images

Red Hat Enterprise Linux 8 Image Builder: Building custom system images

rgerardi
By Ricardo Gerardi

Red Hat Enterprise Linux 8 ships a new tool, called Image Builder, that allows you to create custom Red Hat Enterprise Linux system images in a variety of formats. These include compatibility with major cloud providers and virtualization technologies available in the market. As a result, it enables you to quickly spin up new Red Hat Enterprise Linux (RHEL) systems in different platforms, according to your requirements.

In this article, we’ll show how to set up Image Builder in Red Hat Enterprise Linux 8 and create a couple of images to test its capabilities. Red Hat recommends running Image Builder on its own dedicated virtual machine.

To follow this tutorial, you will need a virtual machine running Red Hat Enterprise Linux 8 where we’ll install Image Builder. This virtual machine needs to be subscribed and have access to the Red Hat Enterprise Linux 8 packages repositories. We’ll not cover Red Hat Enterprise Linux 8 installation in this post. For more information, consult the product documentation.
