Race condition when applying CRDs

Tiltfile:

project = str(local('gcloud config get-value project')).strip()

k8s_yaml(local('capdctl platform -capd-image gcr.io/' + project + '/capd-manager'))

  'gcr.io/' + project +'/capd-manager',
  'go build ./cmd/capd-manager && docker build -t $EXPECTED_REF .',
  ['.'],
  ignore='capd-manager',
)

Everfree.yaml:

---
apiVersion: "cluster.k8s.io/v1alpha1"
kind: Cluster
metadata:
  name: vanhoover
spec:

    services:
      cidrBlocks: ["10.96.0.0/12"]
    pods:

    serviceDomain: "cluster.local"

    command:
      - "bin/bash"
      - "-c"
      - "sleep 10000"

apiVersion: "cluster.k8s.io/v1alpha1"
kind: Machine
metadata:
  name: vanhoover-controlplane-0
  labels:
    cluster.k8s.io/cluster-name: vanhoover

spec:
  versions:
    kubelet: v1.14.4
    controlPlane: v1.14.4
  providerSpec: {}  

Leads me to an error:

ERROR: kubectl apply:
stderr: unable to recognize "STDIN": no matches for kind "Cluster" in version "cluster.k8s.io/v1alpha1"
unable to recognize "STDIN": no matches for kind "Machine" in version "cluster.k8s.io/v1alpha1"
: exit status 1

Is this because the capd-manager isn't running yet?

I'm not familiar with capd (and I'm not super familiar with CRDs in general, so thanks for explaining). What needs to happen for you to not see this error?

1. the CRD is applied
2. the controller for the CRD is up and serving
3. something else entirely?

@liztio I'm curious about this, can you explain the race condition?
