ECR - Ngnix image with multiple sites

Question

I'm working on the deployment of multiple websites with nginx. I want to use ECS for that and create Github actions for automatic deployment on commit. The problem is that I have multiple websites for the same company, and so on, multiple repositories. How can I automatically create an image (ngnix) from different repositories and push it into ECR?

For example, I have 3 repositories: simulator_1, simulator_2, and simulator_3, I want to automatically create a ngnix image that contains simulator_1, simulator_2, and simulator_3 and push it into ECR.

Thanks by advance

Answer 1

Finally, I chose to go to one image per repository / one ngnix server per repository, because it seems that ngnix doesn't take too much performance from the server.
