Deployment issue

Kubernetes
#1

Hello everybody

i’m actually facing an issue while applying my deployment:

I have the below message:

Error from server (BadRequest): error when creating "manifest/front/flaskapp-deployment.yaml": Deployment in version "v1" cannot be handled as a Deployment: json: cannot unmarshal object into Go struct field PodSpec.spec.template.spec.containers of type []v1.Container

Here’s my yaml file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: flaskapp-deployment
  labels:
    app: flaskapp
spec:
  replicas: 1
  selector:
    matchLabels:
      app: flaskapp
  template:
    metadata:
      labels:
        app: flaskapp
    spec:
      containers:
        env:
          - name: MYSQL_DATABASE_DB
            valueFrom:
             secretKeyRef:
                name: flaskapp-credentials
                key:  MYSQL_DATABASE_DB 
          - name: MYSQL_DATABASE_HOST
            valueFrom:
             secretKeyRef:
                name: flaskapp-credentials
                key:  MYSQL_DATABASE_HOST       
          - name: MYSQL_DB_USER
            valueFrom:
             secretKeyRef:
                name: flaskapp-credentials
                key: MYSQL_DB_USER
          - name: MYSQL_USER_PASSWORD
            valueFrom:
             secretKeyRef:
                name: flaskapp-credentials
                key: MYSQL_USER_PASSWORD
        name: flaskapp
        image: p3dr07/macertif:flaskapp-newest
        resources:
          limits:
            memory: 1Gi
            cpu: "0.5"
        ports:
         - containerPort: "5000"
      imagePullSecrets:
        - name: registry-secret

Could you please check what i’m doing wrong in my yaml file ?

Thank you,
