  • Kubernetes v1.13.5
  • Resolve in-addr.arpa reverse DNS lookups (PTR) for pod IPv4 addresses (#415)
    • Reverse DNS lookups for service IPv4 addresses unchanged
  • Upgrade Calico from v3.5.2 to v3.6.0 (#430)
    • Change pod IPAM from host-local to calico-ipam. pod_cidr is still divided into /24 subnets per node, but managed as ippools and ipamblocks
  • Suggest updating terraform-provider-ct from v0.3.0 to v0.3.1 (#434)
  • Announce: Fedora Atomic modules will be not be updated beyond Kubernetes v1.13.x (#437)
    • Thank you Project Atomic team and users, please see the deprecation notice

AWS

  • Support terraform-provider-aws v2.0+ (#419)

Bare-Metal

  • Change the default iPXE kernel and initrd download protocol from HTTP to HTTPS (#420)
    • Require an iPXE-enabled network boot environment with support for TLS downloads. PXE clients must chainload to iPXE firmware compiled with DOWNLOAD_PROTO_HTTPS enabled. (action required)
    • Only affects Container Linux and Flatcar Linux install profiles that pull public images (default)
    • Add download_protocol variable. Recognizing boot firmware TLS support is difficult in some environments, set the protocol to "http" for the old behavior (discouraged)

DigitalOcean

  • Fix kubelet hostname-override to set node metadata InternalIP correctly (#424)
    • Uniquely, DigitalOcean does not resolve hostnames to instance private IPs. Kubelet auto-detect mechanisms require the internal IP be set directly.
    • Regressed in v1.12.3 (#337) which aimed to provide friendly hostname-based node names on DigitalOcean

Addons

  • Update Prometheus from v2.7.1 to v2.8.0
    • Refresh rules based on upstreams (#426)
    • Define NetworkPolicy to allow only traffic from the Grafana addon
  • Update Grafana from v6.0.0 to v6.0.2
    • Add liveness and readiness probes
    • Refresh dashboards and organize to stay below ConfigMap size limit (#426)
  • Remove heapster manifests from addons (#427)
    • Heapster addon powers kubectl top (in early Kubernetes, running the addon was expected). Today, there are better monitoring options.
    • kubectl top reliance on a non-core extension means its not in-scope for minimal Kubernetes
    • Look to prior releases if you still wish to apply heapster
