The Linux Foundation has expanded its portfolio of free-to-audit training courses on the edX platform. The latest one explores running compute in edge locations with Kubernetes and the open source tool K3s.

There is a growing interest in running software at the edge. With this motivation, Introduction to Kubernetes on Edge with K3s is a new self-paced course from the Linux Foundation and Cloud Native Computing Foundation (CNCF) which 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. 

As in the case of its previous Kubernetes course, Introduction to Serverless on Kubernetes it is taught by the Linux Foundation and Alex Ellis, Founder of OpenFaaS and a CNCF Ambassador.

According to its edX description,  the course is designed for those interested learning more about Kubernetes, as well as in deploying applications or embedded sensors in edge locations. By way of pre-requisites, you should be familiar with the Linux Operating System and know how to use common CLI commands to pass arguments, make use of configuration files, and to configure networking. Some prior experience with deploying applications to Kubernetes would be helpful and you need to be able to run Docker on your computer.

The 10-week course, which takes about 15 hours to complete, enables developers to learn about the growing impact the cloud native movement is having on modernizing edge deployments. It covers: 

• Use cases for running compute in edge locations

• How to deploy applications to the edge with open source tools such as K3s and k3sup

• How open source tools can be applied to low-power hardware such as the Raspberry Pi

• The challenges associated with edge compute, such as partial availability and the need for remote access

• Gain experience of deploying applications to Kubernetes and get hands-on with object storage, MQTT and OpenFaaS

• Fleet management and GitOps models of deployment

• Understand messaging and how to interface with sensors and real hardware

Announcing the new course yesterday at KubeCon, its author Alex Ellis said:

“K3s fills a very specific need and helps lower the barrier to entry for development and operation teams,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.”

Auditing the course is free of charge. However if you want to take the final exam or want extended access to it (i.e. for a full year rather than 10 weeks) you need to upgrade to the Verified Track. This has the benefit of  a certificate that can be posted on LinkedIn or added to your resume or CV on successful completion of the course. In the case of Introduction to Kubernetes on Edge with K3s the cost is $149 but you can save 15% (down to $126.65) by upgrading within 7 days of enrolling.
