AS_policys

Description

The module allows you to set list of AutoScaling-Policy with Cloudwatch metric alarms for AutoScaling-group for EKS cluster in AWS. Automatically will be created:

• AutoScaling-Policys
• Cloudwatch metric alarms

WARNING: Different types of AutoScaling-Policy may conflict with each other.

Usage

  {
    estimated_instance_warmup = ""
    adjustment_type           = "ChangeInCapacity"
    policy_type               = "SimpleScaling"
    cooldown                  = "300"
    scaling_adjustment        = "0"
    alarm_name                = "alarm"
    alarm_comparison_operator = "GreaterThanOrEqualToThreshold"
    alarm_evaluation_periods  = "2"
