      Remove support for Calico CNI · 8059eb9f
      Dalton Hubble authored
      * Cilium has been the default for about 3 years and is the defacto
      standard CNI choice. flannel is supported as a simple alternative
      * Remove various historical options that were needed that are
      specific to Calico

      Configure Kubelets for parallel image pulls · a8eae32b
      Dalton Hubble authored
      * By default, Kubelet will pull container images one by one
      (in series), which is mostly related to Docker-era bugs in
      parallel image pulls. These days we use containerd so parallel
      pulls should be fine
      * Serial image pulls are undesirable because one slow registry
      or image can cause other image pulls to wait. Parallel image
      pulls ensure only large images / slow registries see that impact

      Change the default Pod CIDR to 10.20.0.0/14 · 44fc53e8
      Dalton Hubble authored
      * Change the default Pod CIDR from 10.2.0.0/16 to 10.20.0.0/14
      (10.20.0.0 - 10.23.255.255) to support 1024 nodes by default
      * Most CNI providers divide the Pod CIDR so that each node has
      a /24 to allocate to local pods (256). The previous `10.2.0.0/16`
      default only fits 256 /24's so 256 nodes were supported without
      customizing the pod_cidr
