kubernetes – Error trying to create a pod in namespace with kubectl

I’m new to Kubernetes and I’m trying to create a pod inside a namespace.

I have the following namesapce.yaml:

apiVersion: v1
kind: Namespace
metadata:
   name: swirlai

The following configMap.yaml is:

apiVersion: v1
kind: ConfigMap
metadata:
   name: config
   namespace: swirlai
data:
   enviroment: dev # Key - Value
   db-host: localhost # Key - Value
   airflow.cfg:
    dags_folder = ../CodeExample/airflow/dags
    base_log_folder = ../CodeExample/airflow/logs

The secret.yaml is:

apiVersion: v1
kind: Secret
metadata:
  name: secret
  namespace: swirlai
data:
  secret-data: c3VwZXItc2VjcmV0

And the pod.yaml is:

apiVersion: v1
kind: Pod
metadata:
  name: swirlai-pod
  namespace: swirlai
spec:
  containers:
  - name: swirlai-container
    image: nginx:latest
    ports:
    - containerPort: 80
    env:
    - name: DIRECT
      value: Some String
    - name: ENVIRONMENT
      valueFrom:
         configMapKeyRef:
           name: config
           key: environment
    - name: SECRET_DATA
      valueFrom:
         secretKeyRef:
           name: secret
           key: secret-data

After running the “kubectl apply -f pod.yaml” command I can see that I have an error with the command “describe pod -n swirlai”

The error is:

Error: couldn’t find key environment in ConfigMap swirlai/config
