+Todas las variables que se repiten y que, en un principio, no tendría sentido cambiarlas para este chart se marcaron con default.
+
+Por ejemplo, busque los default de service.yaml. Verá que `type` es por defecto "ClusterIP" y que `targetPort` es por defecto `$port`.
+
+Esto tiene dos beneficios:
+
+1) Elimina redundancia en values.yaml
+2) Da libertad para que en un futuro se pueda simplemente modificarlo en `values.yaml`. Por ejemplo, supongamos que queremos cambiar el `type` a "NodePort" en el servicio de `api`, basta con hacer el siguiente cambio:
+
+```yaml
+services:
+  - api:
+    name: "api"
+    tier: "backend"
+    port: 5000
+    type: "NodePort"
+```
+
+----------
+
+En `ingress` se repite el `host` por dos razones:
+
+1) Si quisieran que la api esté en otro dominio se pueda hacer fácilmente mediante:
+
+```yaml
+ingress:
+  annotations:
+    nginx.ingress.kubernetes.io/ssl-redirect: "true"
+  hosts:
+    - host: kube.slc.ar
+      paths:
+        - path: /
+          name: "client"
+          port: 8080
+          pathType: "Prefix"
+    - host: api.kube.slc.ar
+        - path: /
+          name: "api"
+          port: 5000
+          pathType: "Prefix"
+  tls:
+   - secretName: exam-crt
+     hosts:
+       - kube.slc.ar
+       - api.kube.slc.ar
+```
+2) No se pueden reutilizar variables en YAML. Existe la posibilidad de usar YAML anchors pero en la [documentación](https://helm.sh/docs/chart_template_guide/yaml_techniques/#yaml-anchors) no lo recomiendan: "Because Helm and Kubernetes often read, modify, and then rewrite YAML files, the anchors will be lost." 
+
+TODO: probar igual los anchors
