[TECH ED] Docker Compose

### Link to the coursework

https://docs.docker.com/

### Why are we doing this?

Research Docker Compose, its syntax and a few examples. Think how it can help you orchestrate your 3 containers for local development, and then create a docker-compose file to use this tool to automatically build, start and network your containers. Find a way to specify dependencies, to ensure that the backend start initialising only when the database is up and running.

If you want, you can experiment with running all 3 components in EC2 via Docker compose, but keep it as an experiment. Think about some advantages and disadvantages of the 2 approaches (all in a docker-compose file inside a EC2 instance vs using multiple managed services such as S3 and RDS)

### How to get help

If you are doing this for the first time, **this will be hard**. You **must** reach out to volunteers to help you. Your ability to ask for help is actively assessed during this time. Ask good, curious questions with links, code samples, and no screenshots.

You are **not** expected to be able to complete this module completely independently. You **are** expected to get help from volunteers.

### How to submit

In this advanced module you will demo your work. You may wish to make notes for case studies to add to your portfolio.

Comece pelo link do trabalho prático de Docker Compose e inspecione os três contêineres do projeto e sua configuração atual de build e inicialização. Crie um arquivo docker-compose que faça o build, inicie e conecte os contêineres em rede, além de expressar a dependência do banco de dados; valide o workflow local e documente o experimento entre serviços gerenciados e EC2, caso tenha sido tentado.
