awslogs provides two modes for delivering messages from the container to the log driver.

Example

declare const cluster: ecs.Cluster;
// Create a Task Definition for the container to start
const taskDefinition = new ecs.Ec2TaskDefinition(this, 'TaskDef');
taskDefinition.addContainer('TheContainer', {
  image: ecs.ContainerImage.fromAsset(path.resolve(__dirname, '..', 'eventhandler-image')),
  memoryLimitMiB: 256,
  logging: new ecs.AwsLogDriver({ streamPrefix: 'EventDemo', mode: ecs.AwsLogDriverMode.NON_BLOCKING }),
});

// An Rule that describes the event trigger (in this case a scheduled run)
const rule = new events.Rule(this, 'Rule', {
  schedule: events.Schedule.expression('rate(1 minute)'),
});

// Pass an environment variable to the container 'TheContainer' in the task
rule.addTarget(new targets.EcsTask({
  cluster,
  taskDefinition,
  taskCount: 1,
  containerOverrides: [{
    containerName: 'TheContainer',
    environment: [{
      name: 'I_WAS_TRIGGERED',
      value: 'From CloudWatch Events'
    }],
  }],
}));

Name	Description
BLOCKING	(default) direct, blocking delivery from container to driver.
NON_BLOCKING	The non-blocking message delivery mode prevents applications from blocking due to logging back pressure.

BLOCKING

(default) direct, blocking delivery from container to driver.

NON_BLOCKING

The non-blocking message delivery mode prevents applications from blocking due to logging back pressure.

Applications are likely to fail in unexpected ways when STDERR or STDOUT streams block.
