Linux Foundation & CNCF Launch Free Kubernetes on Edge Training

Offered on the edX.org learning platform, the new online course explores use cases and applications of Kubernetes at the edge

SAN FRANCISCO, May 4, 2021The Linux Foundation, the nonprofit organization enabling mass innovation through open source, and Cloud Native Computing Foundation (CNCF), which builds sustainable ecosystems for cloud native software, today at KubeCon + CloudNativeCon Europe (Virtual) announced the availability of a new online training course on edX.org, the online learning platform founded by Harvard and MIT. The course, Introduction to Kubernetes on Edge with K3s (LFS156x), takes a deep dive into the use cases and applications of Kubernetes at the edge using examples, labs, and a technical overview of the K3s project and the cloud native edge ecosystem.

In this 15 hour course, participants will learn the use cases for running compute in edge locations and about various supporting projects and foundations such as LF Edge and CNCF. The course covers how to deploy applications to the edge with open source tools such as K3s and k3sup, and how those tools can be applied to low-power hardware such as the Raspberry Pi. Students will learn the challenges associated with edge compute, such as partial availability and the need for remote access. Through practical examples, students will gain experience of deploying applications to Kubernetes and get hands-on with object storage, MQTT, and OpenFaaS. It also introduces the fleet management and GitOps models of deployment, and helps the student understand messaging, and how to interface with sensors and real hardware.

LFS156x is designed primarily for developers who need to learn about the growing impact the cloud native movement is having on modernizing edge deployments, though others working with Kubernetes or edge computing will find the content of use.

The course was developed by Alex Ellis, a CNCF Ambassador and the Founder of OpenFaaS and inlets. Ellis is a respected expert on serverless and cloud native computing. He founded OpenFaaS, one of the most popular open-source serverless projects, where he has built the community via writing, speaking, and extensive personal engagement. As a consultant and CNCF Ambassador, he helps companies around the world navigate the cloud native landscape and build great developer experiences. Ellis also authored the existing Introduction to Serverless on Kubernetes (LFS157x) course.

“K3s fills a very specific need and helps lower the barrier to entry for development and operation teams,” said Alex Ellis, Founder of Inlets and OpenFaaS, CNCF Ambassador. “I’ve seen the project grow from Darren’s initial post on Hacker News, to a GA, production-ready Kubernetes distribution housed within CNCF. I’m excited to share this course with the community and customers alike, and am looking forward to seeing increased use of Kubernetes at the edge.”

Introduction to Kubernetes on Edge with K3s is available to begin immediately. Auditing the course through edX is free for ten weeks, or participants can opt for a paid verified certificate of completion, which provides access to the course for a full year and additional assessments and content to deepen the learning experience.

Open-source software economics and community health analytics: Enter CHAOSS

George Anadiotis at ZDNet writes:

CHAOSS stands for Community Health Analytics Open Source Software. It’s a Linux Foundation project, and its roots go back 15 years ago. A research team at the University of Juan-Carlos in Madrid, Spain, was trying to understand how software is being built in open source.

There was no tooling to help them do that, so they built their own open-source software. That was the foundation of what is now called GrimoireLab: A set of free, open-source software tools for software development analytics.

The tools gather data from several platforms involved in software development (Git, GitHub, Jira, Bugzilla, Gerrit, Mailing lists, Jenkins, Slack, Discourse, Confluence, StackOverflow, and more), merge and organize it in a database, and produce visualizations, actionable dashboards, and analytics.

Certification Exam Prices Increase July 1 – Lock in Current Pricing

Since we launched our first certification exam in August of 2014, all Linux Foundation performance-based certification exams have been priced at $300. To address the rise in costs associated with administering these exams, we will be implementing a modest price increase effective July 1, 2021. 

All performance-based exams will increase in price from $300 to $375. Bundles of performance-based certifications and their associated training courses will increase from $499 to $575. Bootcamp pricing will also increase in price from $999 to $1,200, and the Linux Foundation Certified IT Associate (LFCA) knowledge-based exam will increase from $200 to $250. We continue to provide the industry’s only free-retake guarantee (an automatic second attempt if your first is unsuccessful on most exams), and are in the process adding other features for exam takers such as an enhanced interface and exam simulation labs.

We strive to make quality open source certifications as accessible as possible so we want to provide plenty of notice, and the old pricing will remain in place through June 30th.

Don’t forget that our Linux exams and training courses including LFCA, LFCE and LFCS are discounted 30% through the end of 2021 in recognition of the 30th anniversary of Linux. Use code LINUX30 at checkout to take advantage of these savings.

The Linux Foundation Announces Open Source Summit + Embedded Linux Conference 2021 Will Move From Dublin, Ireland to Seattle, Washington

Calls for Speaking Proposals close June 13OSPOCon and Linux Security Summit will also move to SeattleAll events will take place September 27 – October 1

SAN FRANCISCO, April 27, 2021The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced today that Open Source Summit + Embedded Linux Conference 2021, along with Linux Security Summit and OSPOCon, will take place in Seattle, Washington, USA, from September 27 – October 1. 

Earlier in the year, it was announced that instead of separate North America and Europe editions of Open Source Summit + Embedded Linux Conference (OS Summit + ELC), only one would be held in 2021, located in Dublin, Ireland. The decision to move these events from Dublin, Ireland to Seattle, Washington, USA, has been made due to the current state of vaccination rates in Europe and upon review of past attendee survey results regarding where and when they would feel comfortable traveling this year.  

OS Summit + ELC will be held in a hybrid format, with both in-person and virtual offerings, to ensure that everyone who wants to participate is able to do so.

KVM Forum, which was also scheduled to take place in Dublin, will now be a virtual event taking place September 15 -16. New details on Linux Plumbers Conference and Linux Kernel Maintainer Summit, also previously scheduled in Dublin, will be announced shortly. A second OSPOCon – OSPOCon Europe, will be held in London on October 6, 2021, with more details coming soon.

Registration for all events will open in June, after more details on local regulations and venue safety plans are available. 

Calls for Speaking Proposals
The Call for Speaking Proposals for OS Summit + ELC and OSPOCon are open through Sunday, June 13 at 11:59pm PDT.  Interested community members are encouraged to apply here. Speakers will be able to speak in person or remotely. 

Linux Security Summit’s Call for Proposals is open through Sunday, June 27 at 11:59pm PDT.  Applications are being accepted here.

BPF: Application Development and libbpf

A while back, I posted a blog series on BPF, including some suggestions about setting up aBPF development environment. Much has changed since then in terms of BPF features, so it’s worth revisiting how BPF applications are developed now.The key change – at least for the BPF projects I work on – is that libbpf has become central to BPF application development. Why?The SYS_BPF…
