"Duplicate value: http" error when it is declared in service.yml file

Description

Declared a deployment.yml file with the following structure:

spec:
  template:
    spec:
      containers:
        - ports:
          - containerPort: 8181
            name: http
            protocol: TCP

Throws the following exception when the application is deployed:

The next definition works successfully:

spec:
  template:
    spec:
      containers:
        - ports:
          - containerPort: 8181
            name: http-web
            protocol: TCP

However the deployment declares finally two ports (http:8080) and (http-web:8181), but my applications has not declared that port as needed.

spec:
  template:
    spec:
      containers:
        - ports:
            - name: http-web
              containerPort: 8181
              protocol: TCP
            - name: http
              containerPort: 8080
              protocol: TCP

IMHO my deployment definition should be used to define the service ports.
