#### Union { #union }

Puedes declarar que una variable puede ser cualquiera de **varios tipos**, por ejemplo, un `int` o un `str`.

Para definirlo usas la <dfn title='también llamado "operador OR a nivel de bits", pero ese significado no es relevante aquí'>barra vertical (`|`)</dfn> para separar ambos tipos.

Esto se llama una "unión", porque la variable puede ser cualquiera en la unión de esos dos conjuntos de tipos.

    
- Kubeadm: improve the validation of serviceSubnet and podSubnet.
  ServiceSubnet has to be limited in size, due to implementation details, and the mask can not allocate more than 20 bits.
  PodSubnet validates against the corresponding cluster "--node-cidr-mask-size" of the kube-controller-manager, it fail if the values are not compatible.
