Lessons Learned from Building a Kubernetes Offering for Small Edge Devices - Daniel Fröhlich, Red Hat

There is a rising demand to use cloud technologies like container orchestration at the far edge. Far edge usually comes with tight resource constraints like very limited compute power (2 cores, 2GB RAM), limited energy (passive cooled on solar energy), only intermitted any slow network connectivity (e.g. mobile/sat networks). MicroShift.io is a Kubernetes distribution targeting these types of environments. In this talk, we share lessons learned on the challenges of designing MicroShift. Topics we will address: - Selecting CNI and CSI implementations - How to embed container images into the device to avoid pulling from remote - How to handle updates/rollback without bricking a device - Fine details on Conformance testing
