Exploring ROS 2 with Kubernetes

Image
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, we construct a prototype ROS 2 system distributed across multiple computers using Kubernetes. Our goal is not only to provide you with a working configuration, but also to help you understand why it succeeds and overcome future design challenges. Getting into Kubernetes can be a pretty steep learning curve, so our prototype will use MicroK8s to make it easy. MicroK8s is a lightweight pure-upstream Kubernetes distribution and offers low-touch, self-healing, highly-available clusters. Its low resource footprint makes it ideal for running on robot computers. Even with very little Kubernet...

OpenStack Charms 20.10 – Victoria, OVN, CNTT and more

Canonical is proud to announce the availability of OpenStack Charms 20.10. This new release introduces a range of exciting features and several improvements which enhance Charmed OpenStack. OpenStack Victoria OpenStack Charms 20.10 brings OpenStack Victoria on Ubuntu 20.04 LTS (via Cloud Archive) and Ubuntu 20.10 with full support from Canonical until April 2022. Victoria is the 22nd release of OpenStack which comes with many interesting features of its own, including solutions for complex networking scenarios. Neutron now provides its metadata service over IPv6 networks which means that users can access it without a configuration drive in IPv6-only networks. Neutron has also added support for flat networks for Distributed Virtual Routers (DVR), Floating IP port forwarding for the OVN backend, and router availability zones in OVN. Octavia load balancer pools now support version two of the PROXY protocol. This allows one to pass client information to member servers when using TCP p...
