[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.

從 Docker Compose 課程作業連結開始，檢查專案的三個容器及其目前的建置與啟動設定。建立一個 docker-compose 檔案，用於建置、啟動並連接這些容器的網路，同時表達對資料庫的相依性；驗證本機工作流程，並在曾經嘗試的情況下記錄託管服務與 EC2 之間的實驗。
