I am trying to create a deployment declaratively, using kubectl apply. The below configuration is created just fine when I do

kubectl create -f postgres-deployment.yaml

but if I go

kubectl apply -f postgres-deployment.yaml

I am presented with the lovely error message:

error: unable to decode "postgres-deployment.yaml": no kind "Deployment" is registered for version "apps/v1beta1"

I have tried searching for an explanation to what this means but I cannot figure it out.

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: postgres-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: postgres
  template:
    metadata:
      labels:
        app: postgres
    spec:
      containers:
      - name: postgres
        image: postgres:10.1
        ports:
        - containerPort: 5432
