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

    docker exec "${C2_NODE}" ip route add "${C1_SVC_CIDR}" via "${C1_DOCKER_IP}"
  fi
}

function install_calico {
  local KUBECONFIG="${1}"
  local CONFIG_DIR="${2}"

  echo "Setting up ambient cluster, Calico CNI will be used."
  kubectl --kubeconfig="$KUBECONFIG" apply -f "${CONFIG_DIR}"/calico.yaml

  kubectl --kubeconfig="$KUBECONFIG" wait --for condition=ready -n kube-system pod -l k8s-app=calico-node --timeout 90s
