Answer 1

更改标识。template应与replicas等处于同一级别

spec:
replicas:
selector:
template:

正确的yaml:

apiVersion: apps/v1
kind: Deployment
metadata:
name: ngx-dep3
labels:
app: ngx
type: webservice
spec:
replicas: 1
selector:
matchLabels:
app: ngx
template:
metadata:
labels:
app: ngx
spec:
containers:
- name: nginx
image: nginx:1.8
kubectl apply -f a.yaml
deployment.apps/ngx-dep3 created
