In the last projects, I started using GitLab, not only as git repository server, but also as DevOps platform. So here I am going to describe a very simple architecture to deploy a single page application using Docker and docker-compose, nginx. In this specific project I used also dotnet-core for the back-end API and VueJS as front-end framework, but it is language-agnostic, meaning that you can replace whatever back-end or front-end you prefer.
