+## Deploy on SMPPIRHOMOLOGA
+
+Whenever you are ready to deploy, please change the `datasources.json` with the `datasources.json.homologa`.
+
+After that, you can use the Docker image:
+
+Para criar a imagem nova
+
+`sudo docker build --tag mapping-api .` 
+
+Para exportar a imagem
+
+`sudo docker save -o ~/mapping-api.tar mapping-api`
+
+Para importar a image
+
+`sudo docker load -i ~/mapping-api.tar ` 
+
+Para rodar a imagem
+
+`sudo docker run -d --rm -p 4001:4001 --net="host" --name mapping-api mapping-api`
+
+
+:warning: O `-d` significa daemon, não quiser que o comando de rodar imagem rode em segundo plano, remova este argumento :warning:
