Talos, with Andrew Rynhard Aug 19, 2021

Show notes

Kubernetes lets us manage our infrastructure declaratively, so why do we still manage the underlying OS with a myriad of different text files? And why allow shell and SSH access to a machine that should be immutable? So asked Andrew Rynhard before creating Talos, a Linux distribution built for Kubernetes. He's now CTO of Talos Systems, a company founded to take it to market.
