Stream docker container logs to the AWS CloudWatch

Configure a role for EC2 instance with permissions to write to the CloudWatch.
Assign that role to EC2 instance with docker.
Open CloudWatch and create docker-logs logging group.
Login into EC2 node and create file

{
  "log-driver": "awslogs",
  "log-opts": {
   "awslogs-group": "docker-logs"
  }
}

Restart docker with

systemctl restart docker

That’s it.

Go to the CloudWatch group and check logs, everything should be there :)
