Which solution will meet these requirements?
Install the Amazon CloudWatch agent on the Amazon EC2 host that runs Fargate.
Configure the awslogs log driver in the ECS task definition.
Configure AWS CloudTrail for the ECS containers.
Install the ECS logs collector on the ECS hosts.
Explanations:
Fargate does not use EC2 instances directly, so installing the CloudWatch agent on EC2 hosts is not applicable. Fargate abstracts away EC2 infrastructure, so the logs should be configured at the ECS task level.
The awslogs log driver can be configured in the ECS task definition to send logs from Fargate tasks directly to Amazon CloudWatch Logs. This meets the requirement of storing logs centrally.
AWS CloudTrail captures API calls for AWS services, not the application-level API calls made by users to the ECS tasks. CloudTrail is useful for tracking AWS service actions but not for application-specific logs.
There is no ECS logs collector for Fargate. The ECS logs collector is for EC2 instances running ECS tasks, but with Fargate, log configuration should be done through the task definition using the awslogs driver.
I gauge that the answer is:
Configure the awslogs log driver in the ECS task definition.
