Я пытаюсь создать правило события AWS Clouwatch через terraform
variable "schedule_expression" {
default = "cron(5 * * * ? *)"
description = "the aws cloudwatch event rule scheule expression that specifies when the scheduler runs. Default is 5 minuts past the hour. for debugging use 'rate(5 minutes)'. See https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/ScheduledEvents.html"
}
Я хочу указать переменную вместо 5
variable "AutoStopSchedule" {
default = "5"
}
variable "schedule_expression" {
default = "cron(${var.AutoStopSchedule} * * * ? *)"
description = "the aws cloudwatch event rule scheule expression that specifies when the scheduler runs. Default is 5 minuts past the hour. for debugging use 'rate(5 minutes)'. See https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/ScheduledEvents.html"
}
но получаю:
Error: variable "schedule_expression": default may not contain interpolations
main.tf
# Cloudwatch event rule
resource "aws_cloudwatch_event_rule" "check-scheduler-event" {
name = "check-scheduler-event"
description = "check-scheduler-event"
schedule_expression = "${var.schedule_expression}"
depends_on = ["aws_lambda_function.demo_lambda"]
}
Я хочу создать выражение schedule_expression на основе переменной AutoStopSchedule, как это сделать?
Попробовал следующее:
resource "aws_cloudwatch_event_rule" "check-scheduler-event" {
name = "check-scheduler-event"
description = "check-scheduler-event"
#schedule_expression = "cron(15 * * * ? *)"
schedule_expression = "${var.AutoStopSchedule == "5" ? cron(5 * * * ? *) : cron(15 * * * ? *)}"
depends_on = ["aws_lambda_function.demo_lambda"]
}
получение expected expression but found "*"
