# cliente-api
API para gerenciar os dados de Clientes. É possível fazer a inclusão, alteração, consulta, listagem e exclusão de clientes.
Neste projeto mostraremos como armazenar arquivos no MySQL.
Para mais vídeos e tutorias acesso o canal [feltex](https://www.youtube.com/c/FeltexBr)
## Pré-requisitos
1. [Java](https://youtu.be/_NCt_82M0MA)
1. [Maven](https://youtu.be/P29usdprI-E)
1. IDE [Intellij](https://youtu.be/Wsm3lbY8_bI) ou [Eclipse](https://youtu.be/veXmZJdyouQ)
1. [MySQL](https://youtu.be/vramc8g9h_s)
1. [Postman](https://youtu.be/tWGi_QKdGHo)
## Configurar banco de dados MySQL
Utilizamos o Docker para executar o MySQL neste exemplo. Para aprender mais sobre
Docker assista a nossa playlist sobre [Docker](https://www.youtube.com/playlist?list=PLoBE72jMC_aL9xp7273MaJad-et_5GFph)
Acesse a pasta docker e execute o comando:
docker-compose up
Se não quiser utilizar o Docker você precisa ter o MySQL instalado no seu computador e precisará criar um banco de dados
com o nome `clientedb`. Atualize o usuário e senha no arquivo `application.properties` para os dados do seu banco de dados
spring.datasource.username=root
spring.datasource.password=feltex
## Iniciar a aplicação
Existem algumas formas de iniciar esta API
java -jar target/cliente-api.jar
ou utilizando o maven
mvn spring-boot:run
## Criando a imagem Docker da API
docker build -t andrefelix/cliente-api:V1 .
docker push andrefelix/cliente-api:V1
## Possíveis problemas
1. Banco de dados não iniciado
