Weighing the options with an Ubuntu 16.04 upgrade Ubuntu 16.04 LTS Xenial Xerus is transitioning from its five-year standard security maintenance window in four months, leaving many asking the question: can I manage an Ubuntu 16.04 LTS upgrade by April 2021, or do I need more time to plan this migration? In the Less than…
This article describes how easy it is for users of Charmed Kubernetes to switch from the Docker container runtime to containerd. You may have heard that Kubernetes is deprecating Docker as a container runtime after v1.20. Docker as an underlying runtime is being deprecated in favor of runtimes that use the Container Runtime Interface(CRI) created…
Ubuntu and Launchpad use OpenPGP keys heavily. Each source package is signed with the uploader’s key, and binary and source package downloads from Ubuntu’s primary archives and from users’ Personal Package Archives (PPAs) are indirectly signed by the publisher process with per-archive keys of its own. Access to Launchpad’s bug-manipulation interface is also controlled by…
One install, one cluster, snap! Today, we’re excited to announce that EKS is available outside of AWS, on any Ubuntu system, with the EKS snap. This announcement builds on the existing collaboration between Amazon and Canonical to ensure the quality, security, and usability of Ubuntu-based EKS clusters on AWS. “Amazon EKS Distro (EKS-D) builds on…
Introduction Our simple ROS 2 talker and listener setup runs well on a single Kubernetes node, now let’s distribute it out across multiple computers. This article builds upon our simple ROS 2 talker / listener setup by running it on multiple K8s nodes. At the completion of this setup expect to have a ROS2 Kubernetes…

Kubernetes provides many critical attributes that can contribute to a robust robotics platform: isolated workloads, automated deployments, self-configuring work processes, and an infrastructure that is both declarative and immutable. However, robots designed with ROS 2 face challenges in setting up individual components on Kubernetes so that all parts smoothly work together. In this blog series,…
