  • Bump up pod short start timeout to 2 minutes. (#69291, @mrunalp)

This allows specifying ranges of allowed GIDs for pods/containers without forcing a default GID the way MustRunAs does. This means that a container to which such a policy applies to won't use any fsGroup/supplementalGroup GID if not explicitly specified, yet a specified GID must still fall in the GID range according to the policy. (#65135, @stlaz)
  • Images for cloud-controller-manager, kube-apiserver, kube-controller-manager, and kube-scheduler now contain a minimal /etc/nsswitch.conf and should respect /etc/hosts for lookups (#69238, @BenTheElder)

  • kubectl: add the --no-headers flag to kubectl top ... (#67890, @WanLinghao)
  • Restrict redirect following from the apiserver to same-host redirects, and ignore redirects in some cases. (#66516, @tallclair)
  • Fixed pod cleanup when /var/lib/kubelet is a symlink. (#68741, @jsafrane)
  • Add "only_cpu_and_memory" GET parameter to /stats/summary http handler in kubelet. If parameter is true then only cpu and memory will be present in response. (#67829, @krzysztof-jastrzebski)
  • Start synchronizing pods after network is ready. (#68752, @krzysztof-jastrzebski)
  • kubectl has gained new --profile and --profile-output options to output go profiles (#68681, @dlespiau)

  • remove unused ReplicasetControllerOptions (#68121, @dixudx)
  • Pass signals to fluentd process (#68064, @gianrubio)
  • Flex drivers by default do not produce metrics. Flex plugins can enable metrics collection by setting the capability 'supportsMetrics' to true. Make sure the file system can support fs stat to produce metrics in this case. (#67508, @brahmaroutu)
  • Use monotonically increasing generation to prevent scheduler equivalence cache race. (#67308, @cofyc)
