ScheduledEc2Task

class aws_cdk.aws_ecs_patterns.ScheduledEc2Task(scope, id, *, scheduled_ec2_task_definition_options=None, scheduled_ec2_task_image_options=None, schedule, cluster=None, desired_task_count=None, enabled=None, rule_name=None, security_groups=None, subnet_selection=None, vpc=None)

Bases: aws_cdk.aws_ecs_patterns.ScheduledTaskBase

A scheduled EC2 task that will be initiated off of CloudWatch Events.

Constructs a new instance of the ScheduledEc2Task class.

Parameters
  • scope (Construct) –

  • id (str) –

  • scheduled_ec2_task_definition_options (Optional[ScheduledEc2TaskDefinitionOptions]) – The properties to define if using an existing TaskDefinition in this construct. ScheduledEc2TaskDefinitionOptions or ScheduledEc2TaskImageOptions must be defined, but not both. Default: none

  • scheduled_ec2_task_image_options (Optional[ScheduledEc2TaskImageOptions]) – The properties to define if the construct is to create a TaskDefinition. ScheduledEc2TaskDefinitionOptions or ScheduledEc2TaskImageOptions must be defined, but not both. Default: none

  • schedule (Schedule) – The schedule or rate (frequency) that determines when CloudWatch Events runs the rule. For more information, see Schedule Expression Syntax for Rules in the Amazon CloudWatch User Guide.

  • cluster (Optional[ICluster]) – The name of the cluster that hosts the service. If a cluster is specified, the vpc construct should be omitted. Alternatively, you can omit both cluster and vpc. Default: - create a new cluster; if both cluster and vpc are omitted, a new VPC will be created for you.

  • desired_task_count (Union[int, float, None]) – The desired number of instantiations of the task definition to keep running on the service. Default: 1

  • enabled (Optional[bool]) – Indicates whether the rule is enabled. Default: true

  • rule_name (Optional[str]) – A name for the rule. Default: - AWS CloudFormation generates a unique physical ID and uses that ID for the rule name. For more information, see Name Type.

  • security_groups (Optional[Sequence[ISecurityGroup]]) – Existing security groups to use for your service. Default: - a new security group will be created.

  • subnet_selection (Optional[SubnetSelection]) – In what subnets to place the task’s ENIs. (Only applicable in case the TaskDefinition is configured for AwsVpc networking) Default: Private subnets

  • vpc (Optional[IVpc]) – The VPC where the container instances will be launched or the elastic network interfaces (ENIs) will be deployed. If a vpc is specified, the cluster construct should be omitted. Alternatively, you can omit both vpc and cluster. Default: - uses the VPC defined in the cluster or creates a new VPC.
