ScheduledFargateTask

class aws_cdk.aws_ecs_patterns.ScheduledFargateTask(scope, id, *, platform_version=None, scheduled_fargate_task_definition_options=None, scheduled_fargate_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: ScheduledTaskBase

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

ExampleMetadata:: infused

Example:

# cluster: ecs.Cluster

scheduled_fargate_task = ecs_patterns.ScheduledFargateTask(self, "ScheduledFargateTask",
    cluster=cluster,
    scheduled_fargate_task_image_options=ecsPatterns.ScheduledFargateTaskImageOptions(
        image=ecs.ContainerImage.from_registry("amazon/amazon-ecs-sample"),
        memory_limit_mi_b=512
    ),
    schedule=appscaling.Schedule.expression("rate(1 minute)"),
    platform_version=ecs.FargatePlatformVersion.LATEST
)

Constructs a new instance of the ScheduledFargateTask class.

Parameters:

scope (Construct)
id (str)
platform_version (Optional[FargatePlatformVersion]) – The platform version on which to run your service. If one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide. Default: Latest
scheduled_fargate_task_definition_options (Union[ScheduledFargateTaskDefinitionOptions, Dict[str, Any], None]) – The properties to define if using an existing TaskDefinition in this construct. ScheduledFargateTaskDefinitionOptions or ScheduledFargateTaskImageOptions must be defined, but not both. Default: none
scheduled_fargate_task_image_options (Union[ScheduledFargateTaskImageOptions, Dict[str, Any], None]) – The properties to define if the construct is to create a TaskDefinition. ScheduledFargateTaskDefinitionOptions or ScheduledFargateTaskImageOptions 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 (Union[SubnetSelection, Dict[str, Any], None]) – 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.
