Terraform snippet

You can easily integrate it in your Terraform project using a null_resource which is triggered by a task definition change:

resource "null_resource" "deploy" {
  triggers = {
    task_definition_arn = aws_ecs_task_definition.api.arn
  }

  provisioner "local-exec" {
    command = <<EOT
      codedeploy-trigger \
        -applicationName "codedeploy-application-name" \
        -deploymentGroupName "codedeploy-deployment-group-name" \
        -containerName "container-name" \
        -containerPort "1337" \
        -taskDefinitionARN "${aws_ecs_task_definition.api.arn}"
    EOT
  }
}
