Guru Night at Red Hat Summit: Hands-on experience with serverless computing

Guru Night at Red Hat Summit: Hands-on experience with serverless computing

Millions of developers worldwide want to learn more about serverless computing. If you’re one of the lucky thousands attending Red Hat Summit in Boston May 7-9, you can gain hands-on experience with the help of Burr Sutter and the Red Hat Developer team.

Guru Night is a BYOL (bring your own laptop) event taking place Wednesday, May 8 from 5:00 p.m. to 8:00 p.m. at the Boston Convention and Event Center in ML2 East-258AB. (Doubtless there will be a map to show you where or what ML2 East etc. is; we have no idea.) Head to the signup page and fill out your details now.

TL;DR: Beer and pizza will be served.

We felt compelled to point that out. But read on.

Podman basics cheat sheet

Podman basics cheat sheet

Here and elsewhere, we get a lot of questions about post-Docker container tools in Red Hat Enterprise Linux 7.6 and Red Hat Enterprise Linux 8 beta. Tools like podman, buildah, and skopeo enable you to create and manage rootless containers, which are containers that don’t require root access to be built and deployed. To help you master the basics, we’re happy to offer a new podman basics cheat sheet.

Kubernetes v1.14: What you need to know

Kubernetes v1.14: What you need to know

Kubernetes v1.14 was released today. The primary themes of the release are extensibility and supporting more workloads. It includes 31 enhancements, with a record 10 features graduating from beta to stable. Here are the highlights:

Persistent local storage

This feature, which was previously available as a beta, is now classified as stable. The primary use cases for persistent local storage are databases and distributed file systems. Obviously, local storage performs better than remote disks, whether that storage is a local SSD delivered by a cloud provider or a disk attached to a bare metal system. This has been in the works since Kubernetes v1.5, so its promotion to stable status is a significant milestone.

An overview of Eclipse Che

An overview of Eclipse Che

This video is a brief overview of Eclipse Che presented by CodeReady Workspaces Product Manager Stévan Le Meur. The tour starts in a git repo that contains a link to a Che factory. Opening that factory loads the code from the git repo and sets up a complete development environment. From there, Stévan covers how to build, run, and debug the code within Che.

CodeReady Workspaces for OpenShift (Beta) – It works on their machines too

CodeReady Workspaces for OpenShift (Beta) – It works on their machines too

“It works on my machine.” If you write code with, for, or near anybody else, you’ve said those words at least once. Months ago I set up a library or package or environment variable or something on my machine and I haven’t thought about it since. So the code works for me, but it may take a long time to figure out what’s missing on your machine.

Code Ready Workspaces and Factories

Built on the open-source Eclipse Che project, CodeReady Workspaces solves this problem (and a couple of others that we’ll talk about in a minute) by delivering secure, sharable developer workspaces. Those workspaces include all the tools and dependencies needed to code, build, test, run, and debug your applications. The entire product runs in an OpenShift cluster (on-premises or in the cloud), so there’s nothing to install on your machine. Or mine.

Modernize your application deployment with Lift and Shift

Modernize your application deployment with Lift and Shift

For many software modernization projects, it’s all about learning to love, lift, and shift. No, wait. It’s all about learning to love lift and shift. The basic idea behind lift and shift is to modernize how an existing application is packaged and deployed. Because it’s not about rewriting the application itself, lift and shift is typically quick to implement.

Modern development environments rely on containers for packaging and deployment. A modern environment also uses a continuous integration / continuous deployment (CI/CD) system that automatically builds, tests, and deploys an application whenever its source code changes.

EclipseCon Europe: Che sessions by Red Hatters

EclipseCon Europe: Che sessions by Red Hatters

EclipseCon Europe is almost here, and many Red Hatters are working furiously to make the show as valuable as possible for attendees. (We’re partly doing it for ourselves as well, of course, because it’s a great opportunity to get the entire Che/Theia community together.)  If you aren’t familiar with Eclipse Che, it’s is a next-generation cloud IDE and developer workspace server for teams and organizations. Theia is an extensible open-source framework to develop multi-language IDEs for the cloud and desktop using state-of-the-art web technologies.

The conference will be held next week on October 22–25 in Ludwigsburg, Germany. Here’s a rundown of what will be offered.
