Red Hat simplifies container development and redistribution of Red Hat Enterprise Linux packages

Red Hat simplifies container development and redistribution of Red Hat Enterprise Linux packages

Application developers in the Red Hat Partner Connect program can now build their container apps and redistribute them from the full set of Red Hat Enterprise Linux (RHEL) user space packages (non-kernel). This nearly triples the number of packages over UBI only.

When we introduced Red Hat Universal Base Images (UBI) in May 2019, we provided Red Hat partners the ability to freely use and redistribute a substantial number of RHEL packages that can be deployed on both Red Hat and non-Red Hat platforms. This gave developers the ability to build safe, secure, and portable container-based software that could then be deployed anywhere. The feedback on this has been overwhelmingly positive and we thank you for it, but we learned that you needed more, so we’re sharing this advanced preview with Red Hat Partner Connect members to help you with your planning. 

Expanded and exclusive redistribution rights for Red Hat Technology Partners

We are pleased to announce expanded partner terms and conditions that grant Red Hat Technology Partners free use and redistribution rights to all Red Hat Enterprise Linux user space packages when you build upon UBI-based images. With more than triple the number of RHEL packages now available, you can simplify your container and Operator development and freely re-distribute your container-based software through both Red Hat and non-Red Hat registries. This is only available to Red Hat partners who participate in and complete Red Hat Container Certification.

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.

Red Hat Universal Base Image: How it works in 3 minutes or less

When we announced Red Hat Enterprise Linux 8 in May, we also announced that all RHEL 8 base operating systems images, and many new RHEL 7 ones, would be available under the new Universal Base Image End User License Agreement (EULA). If UBI is new for you, this article summarizes UBI, explains why you’d want to use it, and supplies a set of resources to get you started with UBI.  And, if you have questions, we just published a brand new UBI FAQ.
