OBJETIVO

O projeto tem como finalidade, a criação de um ambiente de desenvolvimento para uma aplicação web, utilizando a plataforma Docker. Toda a arquitetura foi desenvolvida em conjunto com os alunos Lucas Gabriel Moya Arantes Pereira e João Gustavo Rodrigues.

ESTRUTURA

• Toda base de código utilizada no back-end e front-end possui a seguinte estrutura:
