on line 20 during Deployment creation. looks good to me though.

```auto
apiVersion: apps/v1
kind: Deployment
metadata:
  name: webserver
  labels:
    app: nginx
spec:
  replicas: 3
  selector:
    matchlabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:alpine
        ports:
        - containerPort: 80

Copying directly, I get this error:

```auto
error: error validating "test.yaml": error validating data: 
ValidationError(Deployment.spec.selector): unknown field "matchlabels" in
io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelector;
if you choose to ignore these errors, turn validation off with
--validate=false

```

you need to capitalize the L in the match labels selector:

`matchlabels` -\> `matchLabels`

After doing that it worked for me.

Yeah, I see that now. I wish it had said something about that instead of an indentation error.  
Is that test.yaml file something you custom made ?

I copied and pasted the yaml you posted into a text file and called it `test.yaml` 👍

You got a different error message than I did. did you pass the file to kubectl ?

Yup – all I did was: `kubectl create -f test.yaml`
