  # To enable the PodDisruptionBudget, configure it by specifying the

  # minimum number of available replicas to 1, you can update this value as follows:
  #
  # podDisruptionBudget:
  #   minAvailable: 1
  #
  # Or, to allow a maximum of 1 unavailable replica, you can set:
  #
  # podDisruptionBudget:
  #   maxUnavailable: 1

  // The maximum number of nodes with an existing available DaemonSet pod that
  // can have an updated DaemonSet pod during during an update.
  // Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%).
  // This can not be 0 if MaxUnavailable is 0.
  // Absolute number is calculated from percentage by rounding up to a minimum of 1.

This is a work in progress - building on top of the multi-cluster installer.

As an extreme, the goal is to be possible to run Istio workloads in a cluster without installing any Istio component
in that cluster. Currently, the minimum we require is the security provider (node agent or citadel).

### Install Istio CRDs

This is the first step of the installation. Please do not remove or edit any CRD - config currently requires
