Cloud Resource LifeCycle Scheduler

Cloud resource lifecycle scheduler to save and avoid surprising cost. Cloud resource lifecycle scheduler allows you to automatically cleanup temporary workloads such as EC2 instances depending on the lifecycle that you set through resource tag.

Note: EventBridge will trigger CloudCycle every 15 minutes.

Usage

Just specify that tag and set your desired lifecycle for supported resources with CloudCycle Key. Below is the supported duration.

Suffixes	Detail	Sample Value
m	Minutes	60m
h	Hours	2h
d	Days	7d

How does it works?

CloudCycle will get all the supported resources with a tagged key CloudCycle and it will simply compare the current time vs launch time of the supported resources with the specified key/value pair resource tag if the supported resources are valid for termination.

Below are the sample terraform code.

Specify ec2 lifecycle by 24 hours from it's launch date.

data "aws_ami" "ubuntu" {
  most_recent = true

  filter {
    name   = "name"
    values = ["ubuntu/images/hvm-ssd/ubuntu-jammy-22.04-amd64-server-*"]
  }

  filter {
    name   = "virtualization-type"
    values = ["hvm"]
  }

  owners = ["099720109477"] # Canonical
}

resource "aws_instance" "web" {
  ami           = data.aws_ami.ubuntu.id
  instance_type = "t3.micro"

  tags = {
    CloudCycle = "1d" // This ec2 instance will be terminated within 24 hours from it's launch date.
  }
}
