 ## Build Simples da API 
 
 ```
-    $ docker build . -t example/api
+$ docker build . -t example/api
 ```
 
 ## Build da API no Developer Mode com o Compose v2
 
 ```
-    $ docker-compose up -d 
+$ docker-compose up -d 
 ```
 
 ## Deploy da API no Swarm Mode - Compose v3
 
 ```
-    $ docker stack deploy -c docker-compose-prodswarm.yml app
+$ docker stack deploy -c docker-compose-prodswarm.yml app
+```
+
+### Verificando a distribuição dos containers
+
+```
+$ docker stack ps app
+```
+```

+### Escalando a API 
+
+Verificando os services disponíveis
+
+```
+$ docker stack services app
+```
+```
+ID                  NAME                MODE                REPLICAS            IMAGE

+docker@master:~$ docker stack services app
+```
+
+```
+$ docker service scale app_api=10
+app_api scaled to 10
+```
+
+Podemos olhar novamente agora e...
+
+```
+$ docker stack services app
+```
+
+```
