Running the directed command: kubectl patch deployment ingress-nginx-controller --patch "$(cat ingress-nginx-controller-patch.yaml)" -n kube-system results in an error The Deployment "ingress-nginx-controller" is invalid: spec.template.spec.containers[0].image: Required value.

EDIT:
I think the real problem is that the container name mentioned in the docs is ingress-nginx-controller. The deployment ingress-nginx-controller has container controller. That container is what should be patched.

From the docs:

spec:
  template:
    spec:
      containers:
      - name: ingress-nginx-controller
        ports:
         - containerPort: 6379
           hostPort: 6379
