Dalton Hubble 4cfafeaa07 Fix Kubelet starting before hostname set on FCOS AWS
* Fedora CoreOS `kubelet.service` can start before the hostname
is set. Kubelet reads the hostname to determine the node name to
register. If the hostname was read as localhost, Kubelet will
continue trying to register as localhost (problem)
* This race manifests as a node that appears NotReady, the Kubelet
is trying to register as localhost, while the host itself (by then)
has an AWS provided hostname. Restarting kubelet.service is a
manual fix so Kubelet re-reads the hostname
* This race could only be shown on AWS, not on Google Cloud or
Azure despite attempts. Bare-metal and DigitalOcean differ and
use hostname-override (e.g. afterburn) so they're not affected
* Wait for nodes to have a non-localhost hostname in the oneshot
that awaits /etc/resolve.conf. Typhoon has no valid cases for a
node hostname being localhost (not even single-node clusters)

Typhoon

Typhoon is a minimal and free Kubernetes distribution.

  • Minimal, stable base Kubernetes distribution
  • Declarative infrastructure and configuration
  • Free (freedom and cost) and privacy-respecting
  • Practical for labs, datacenters, and clouds

Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.

Features

  • Kubernetes v1.18.4 (upstream)
  • Single or multi-master, Calico or flannel networking
  • On-cluster etcd with TLS, RBAC-enabled, network policy, SELinux enforcing
  • Advanced features like worker pools, spot workers, and snippets customization
  • Ready for Ingress, Prometheus, Grafana, CSI, and other optional addons
