如何在已经通过Terraform和GitHub Action启动的AWS EC2机器中使用Docker-Compose？

我有一个简单的小网络应用程序，该应用程序由四个带有烧瓶应用程序的Docker容器和一个Docker-Compose文件组成。他们通过消息队列通信。对于本地启动该应用程序，我只需使用Docker-Compose。然后，可以通过Localhost上的网关访问所有Web应用程序：5004。

现在，我试图以下面的方式自动化部署：

每次我推到github repo时，通过github操作的工作流程开始启动
此工作流程将连接到Terraform Cloud（在Terraform.yml中指定）
Terraform创建一个新的AWS EC2实例端口5004打开（在main.tf中指定）
，这里出现了问题...

在本地，我将

使用“ SCP -R -I -i my_key .pem ”将文件复制到EC2计算机。 pathtoproject ec2-user@ publicip ：〜/“
ssh进入ec2机器
安装docker and docker-compose
do doce do docker-compose
在此之后，我可以使用 publicip：5004

我该如何通过github动作和Terraform做到这一点？

我已经尝试了以下操作：

在main.tf中：使用EC2计算机的用户_DATA属性添加启动计算机后应执行的命令。问题：我不知道如何从存储库中复制文件或克隆EC2计算机内的存储库。要复制，我需要正确的路径（显然，它不仅仅是指向文件的链接）。对于克隆，我需要在EC2计算机内创建一个新的SSH键，然后手动将其添加到我的GitHub帐户中 - 但是由于它应该是自动化的，因此这不是解决方案。
另一个选择是使用我的容器的公共码头图像 - 它们也是由另一个github动作创建的。但是我仍然有同样的问题：我必须以某种方式上传 /复制 /克隆docker-compose文件到EC2计算机。
我还试图通过GitHub操作直接进行操作，并仅将Terraform用于机器的创建，但是由于我每次都在创建新机器，因此EC2机器的IP地址总是会更改。但是我需要SSH-ing在...

我希望我能够准确描述这个问题，如果不是，我很抱歉，我是所有CI/CD材料的新手：-)。

最好的问候，谢谢 Jana

I have a simple little web application that consists of four docker containers with flask apps in them and a docker-compose file. They communicate via a message queue.
For starting the app locally, I simply use docker-compose up.
Then, all the web apps can be accessed via a gateway on localhost:5004.

Now I am trying to automate the deployment in the following way:

Every time I push to the GitHub repo, a workflow via Github Actions is started
This workflow connects to Terraform Cloud (specified in terraform.yml)
Terraform creates a new AWS EC2 instance with port 5004 opened (specified in main.tf)
And here comes the problem...

Locally, I would now

copy the files to the EC2 machine with "scp -r -i my_key.pem pathtoproject ec2-user@publicIP:~/"
ssh into the EC2 machine
install docker and docker-compose
do docker-compose up
After that, I am able to access my app with publicIP:5004

How can I do that via Github Actions and Terraform?

I already tried the following:

In main.tf: Use the user_data property of the EC2 machine for adding commands that should be executed after starting the machine. Problem here: I don't know how I can copy the files from the repository or clone the repository inside the EC2 machine. For copying, I would need the correct path (apparently, it is not simply the link to the file). For cloning, I would need to create a new SSH key inside the EC2 machine and add it manually to my github account - but since it should be automated, this is not a solution.
Another option would be to use the public docker images of my containers - they are also being created by another Github Action. But still here, I have the same problem: I would have to somehow upload / copy / clone the docker-compose file to the EC2 machine.
I also tried to do it directly via Github Actions and using Terraform solely for the creation of the machine, but since I am creating a new machine every time, also the IP address of the EC2 machine always changes. But I need that for ssh-ing in...

I hope I was able to describe the issue accurately, if not, I am sorry, I am new to all the CI/CD stuff :-).

Best regards and thanks,
