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

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.

.NET Core 3.0 for Red Hat Enterprise Linux 7 now available

.NET Core 3.0 for Red Hat Enterprise Linux 7 now available

We are very excited to announce the general availability of .NET Core 3.0 for Red Hat Enterprise Linux 7! .NET Core is the open source, cross-platform .NET platform for building microservices. .NET Core is designed to provide the best performance at scale for applications that use microservices and containers.

.NET Core 3.0 is available today on Red Hat Enterprise Linux 7 via “yum” in the /dotnet repo, and in container images from the Red Hat Container Catalog. Availability for Red Hat Enterprise Linux 8 will come with the release of RHEL 8.1 in Application Streams.

CI/CD for .NET Core container applications on Red Hat OpenShift

CI/CD for .NET Core container applications on Red Hat OpenShift

Many people have done continuous integration and continuous delivery (CI/CD) for .NET Core, but they still may wonder how to implement this process in Red Hat OpenShift Container Platform (OCP). The information is out there, but it has not been structurally documented. In this article, we’ll walk through the process.

Eclipse Che 7 and the .NET developer

Eclipse Che 7 and the .NET developer

Eclipse Che 7, an open source in-the-browser development environment, allows you to define custom workspaces for your software development. Think of a workspace as you would think of a development PC: You have an operating system, programming language support, and all the tools necessary to write code. In this article, I’ll introduce the .NET developer to this new world and highlight ways you can use Eclipse Che to your advantage.

What is Red Hat Universal Base Image?

What is Red Hat Universal Base Image?

Back in May, we launched the Red Hat Universal Base Image (UBI), targeted at developers building containerized applications for the cloud. Since then, we have published an extensive FAQ covering topics ranging from how often UBI is updated, to how the end user license agreement (EULA) allows you to redistribute applications built on it. These are all great fundamental topics to cover, but people still seem to have a lot of questions around what UBI is and what it isn’t.

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.

Develop with Node.js in a container on Red Hat Enterprise Linux

Develop with Node.js in a container on Red Hat Enterprise Linux

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 Node using the current RHEL 8 application stream versions of Node.js and Redis 5.

Develop with Flask and Python 3 in a container on Red Hat Enterprise Linux

Develop with Flask and Python 3 in a container on Red Hat Enterprise Linux

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 the Flask microframework using the current RHEL 8 application stream version of Python 3.

From my perspective, using Red Hat Enterprise Linux 8 application streams in containers is preferable to using software collections on RHEL 7. While you need to get comfortable with containers, all of the software installs in the locations you’d expect. There is no need to use scl commands to manage the selected software versions. Instead, each container gets an isolated user space. You don’t have to worry about conflicting versions.
