如何使用亚马逊 ecs 运行 15 个 docker 容器

Question

My dockerized application has 12 services in docker-compose.yml, now I want to deploy this application on AWS ECS so any idea how to do that?

In task definition, we can add only up to 10 containers, also is there a way to add multiple task definitions in services?

Answer 1

You should not put all the service in a single task definition, better to run each task in a separate service and for service to service communications use service discovery or internal load balancer .

In task definition, we can add only up to 10 containers, also is there a way to add multiple task definitions in services

Beside 10 containers limit, there are many other issues with this approach

• You can not scale one container , for example scaling PHP container will scale Nginx as well
• Hard to maintain replica and essential container for the service
• Not a production grade approach as it uses linking for service to service communication
• Fewer resources utilization

Or if you need a quick fix then break the task definition into a dependency group, create two task definition for depended containers so they will able to communicate with each other being part of the same task definition.
