Inputs

Name	Description	Type	Default	Required
appautoscaling_high_cpu_threshold	The value against which the specified statistic is compared. This parameter is required for alarms based on static thresholds, but should not be used for alarms based on anomaly detection models.	number	65	no
appautoscaling_low_cpu_threshold	The value against which the specified statistic is compared. This parameter is required for alarms based on static thresholds, but should not be used for alarms based on anomaly detection models.	number	15	no
appautoscaling_max_capacity	The max capacity of the scalable target.	number	10	no
appautoscaling_min_capacity	The min capacity of the scalable target.	number	2	no
appautoscaling_scale_down_adjustment	The number of members by which to scale, when the adjustment bounds are breached. A positive value scales up. A negative value scales down.	number	-1	no
appautoscaling_scale_down_cooldown	The amount of time, in seconds, after a scaling activity completes and before the next scaling activity can start.	number	150	no
appautoscaling_scale_up_adjustment	The number of members by which to scale, when the adjustment bounds are breached. A positive value scales up. A negative value scales down.	number	2	no
appautoscaling_scale_up_cooldown	The amount of time, in seconds, after a scaling activity completes and before the next scaling activity can start.	number	60	no
ecs_assign_public_ip	Whether to assign a public IP to the Fargate tasks.	bool	false	no
ecs_cluster_name	Name of an existing ECS Cluster.	string	n/a	yes
ecs_container_name	The container name value, already specified in the task definition, to be used for your service discovery service.	string	n/a	yes
ecs_container_port	The port value, already specified in the task definition, to be used for your service discovery service.	number	80	no
ecs_deployment_maximum_percent	The upper limit (as a percentage of the service's desiredCount) of the number of running tasks that can be running in a service during a deployment.	number	200	no
ecs_deployment_minimum_healthy_percent	The lower limit (as a percentage of the service's desiredCount) of the number of running tasks that must remain running and healthy in a service during a deployment.	number	100	no
ecs_desired_count	The number of instances of the task definition to place and keep running.	number	2	no
ecs_health_check_grace_period_seconds	Seconds to ignore failing load balancer health checks on newly instantiated tasks to prevent premature shutdown, up to 2147483647.	number	0	no
ecs_security_group_ids	A list of security groups associated with the task or service.	list(string)	n/a	yes
ecs_task_definition_arn	The family and revision (family:revision) or full ARN of the task definition that you want to run in your service.	string	n/a	yes
lb_health_check_enabled	The number of consecutive health checks successes required before considering an unhealthy target healthy.	bool	true	no
lb_health_check_healthy_threshold	The number of consecutive health checks successes required before considering an unhealthy target healthy.	number	3	no
lb_health_check_interval	The approximate amount of time, in seconds, between health checks of an individual target. Minimum value 5 seconds, Maximum value 300 seconds.	number	30	no
lb_health_check_matcher	The HTTP codes to use when checking for a successful response from a target. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299").	string	"200-299"	no
lb_health_check_path	The destination for the health check request.	string	"/"	no
lb_health_check_timeout	The amount of time, in seconds, during which no response means a failed health check. The range is 2 to 120 seconds, and the default is 5 seconds.	number	5	no
lb_health_check_unhealthy_threshold	The number of consecutive health check failures required before considering the target unhealthy.	number	3	no
name	Name of the ECS Service.	string	n/a	yes
private_subnet_ids	A list of private subnets.	list(string)	[]	no
public_subnet_ids	A list of public subnets.	list(string)	[]	no
stage	Stage of the ECS Service, e.g staging, beta, qa, prod.	string	n/a	yes
tags	Key-value map of resource tags.	map(string)	n/a	yes
vpc_id	The identifier of the VPC in which to create the resources.	string	n/a	yes
