ELK on ECS

[Khaldoun488]

Thanks @maxpou .

I am using my app in production on AWS ECS and I have some questions about ELK.

In my task definition, i added 3 containers : php-fpm, nginx and elk.

In elk, i specified the volumes_from by adding the php/nginx sources containers.

This is my task definition :
