Olá pessoal, tudo bem?

Após criar os arquivos de deployment estou tomando este erro:

PDOException Object ( [message:protected] => SQLSTATE[HY000] [2002] No such file or directory [string:Exception:private] => [code:protected] => 2002 [file:protected] => /var/www/html/funcoes.php [line:protected] => 7 [trace:Exception:private] => Array ( [0] => Array ( [file] => /var/www/html/funcoes.php [line] => 7 [function] => __construct [class] => PDO [type] => -> [args] => Array ( [0] => mysql:host=;dbname= [1] => [2] => ) ) [1] => Array ( [file] => /var/www/html/index.php [line] => 6 [args] => Array ( [0] => /var/www/html/funcoes.php ) [function] => include ) ) [previous:Exception:private] => [errorInfo] => )

Já recriei e revisei os módulos de sistema-noticia e db-noticias mas eles estão iguais ao do instrutor.

Eu uso mac e estou utilizando o minikube para usar a estrutura do kubernets.

Segue os arquivos de deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: sistema-noticias-deployment
spec:
  replicas: 1
  template:
    metadata:
      name: sistema-noticias
      labels:
        app: sistema-noticias
    spec:
      containers:
        - name: sistema-noticias-container
          image: aluracursos/sistema-noticias:1
          ports:
            - containerPort: 80
          envFrom:
            - configMapRef:
                name: sistema-configmap
  selector:
    matchLabels:
      app: sistema-noticias

          image: aluracursos/mysql-db:1
          ports:
            - containerPort: 3306
          envFrom:
            - configMapRef:
                name: db-configmap
  selector:
    matchLabels:
      app: db-noticias

Desde já agradeço!
