ECS does not start the instance, "cannot set the task because resources cannot be found."

Question

I can’t understand why my ecs service does not start and does not receive the error message “the service cannot post the task because the resources cannot be found”.

In my task definition, I have 500 processor units and 250 memory, for just a small example of a node application that just serves my static assets.

I start my service with 1 task and without ELB.

I assume your processors are too high. https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html#container_definition_environment

this is a more complex metric to guess if you have not actually measured it in your application.

In any case, I encounter a similar problem, so I’m right there in the same boat, but I would try to erase the processor, since it is optional, and see if it allows it.
