Package awslogs provides the logdriver for forwarding container logs to Amazon CloudWatch Logs
New creates an awslogs logger using the configuration passed in on the context. Supported context configuration variables are awslogs-region, awslogs-group, and awslogs-stream. When available, configuration is also taken from environment variables AWS_REGION, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, the shared credentials file (~/.aws/credentials), and the EC2 Instance Metadata Service.
ValidateLogOpt looks for awslogs-specific log options awslogs-region, awslogs-group, and awslogs-stream
