In today’s world of containers and abstraction, we’re told OS choice doesn’t matter—but in reality, compliance, licensing, and in-house expertise make it critical. The same goes for your Kubernetes flavor. Yet, setting up infra shouldn’t be tedious. Kairos Factory brings the “poke bowl” experience to Kubernetes infrastructure: a web-based builder to assemble secure, immutable OS images tailored to your needs. Pick your base OS, choose your K8s (k3s, k0s), and add your config “toppings”—from VPNs to TPM-backed boot. Unlike rigid, opinionated stacks, Kairos is truly composable: swap layers as you like, no lock-in. In this talk, see live demos and real-world use cases showing how teams use Kairos to gain flexibility and control across edge, bare metal, or cloud—without giving up existing know-how or security. Build your own Kubernetes Poke Bowl, and maybe leave hungry for sushi.
