Which solution will meet this requirement?
Turn on the awslogs log driver by specifying parameters for awslogs-group and awslogs-region in the LogConfiguration property.
Download and configure the CloudWatch agent on the container instances.
Set up Fluent Bit and FluentD as a DaemonSet to send logs to Amazon CloudWatch Logs.
Configure an IAM policy that includes the logs:CreateLogGroup action. Assign the policy to the container instances.
Explanations:
By using theawslogslog driver in the task definition, you can configure ECS to send container logs directly to CloudWatch Logs. Theawslogs-groupandawslogs-regionparameters specify the CloudWatch log group and region for the logs. This is the recommended and simplest approach for Fargate tasks.
The CloudWatch agent is typically used on EC2 instances, not in Fargate, since Fargate does not manage EC2 instances. Fargate requires the logging configuration to be set up within the ECS task definition itself.
Fluent Bit and FluentD are useful for log aggregation in certain environments, but they are not necessary or optimal for Fargate containers. The ECS service on Fargate can directly use theawslogslog driver for CloudWatch integration. This introduces additional complexity without a clear benefit in this case.
While setting up an IAM policy withlogs:CreateLogGroupis required for permissions, this alone will not send logs to CloudWatch. The logging configuration within the ECS task definition (like theawslogslog driver) is needed to specify how logs are collected and forwarded.
I compute that the answer is:
Turn on the awslogs log driver by specifying parameters for awslogs-group and awslogs-region in the LogConfiguration property.
