His favorite enhancements:

  • Dual-stack IPv4/IPv6 is GA
  • PodSecurity Admission goes to beta (PSP replacement)
  • TTL Controller (Cleanup Jobs and Pods of Jobs) goes to GA
  • HPA v2 API is GA
  • Ephemeral Containers (supports kubectl debug) goes to beta
  • Auto remove PVCs from StatefulSets is intro'd as alpha
  • SLSA Level 1 compliance (provenance attestation files are generated that describe staging and release phases)
  • Quick review:
    • Kubelet CRI went to beta (pre docker-shim)
    • Supply chain: taint based propagation analysis. How does data move within an application and make sure we don't log secrets.
