Cloudoff

Cloudoff is a lightweight Go application designed to automate the management of AWS EC2 instances. It helps reduce cloud costs by automatically stopping instances at night, restarting them during the day, and cleaning up instances that have exceeded their Time-To-Live (TTL).

🚀 Features

  • ⏰ Scheduled stop and start of EC2 instances (e.g., stop at night, start in the morning)
  • 🧹 Automatic cleanup of EC2 instances after their TTL expiration
  • 📊 Optimizes cost by limiting the runtime of non-critical resources
  • 🔒 Follows AWS best practices (tag-based selection, IAM roles, etc.)

🔧 Requirements

  • Go 1.18+
  • AWS credentials with EC2 management permissions (via environment or IAM role)
  • Tagged EC2 instances (see below)

🛠️ Installation

git clone https://github.com/bananaops/cloudoff.git
cd cloudoff
go build -o cloudoff

⚙️ Usage

🏷️ EC2 Tags Used by Cloudoff

Cloudoff relies on specific EC2 tags to determine which instances to manage and when to clean them up.

Tag KeyExample ValueDescription
cloudoff:uptimeMon-Fri 08:00-20:00 Europe/ParisSpecifies when the instance should be running. Timezone must be specified.
cloudoff:downtimeSat-Sun 00:00-23:59 Europe/ParisSpecifies when the instance must be stopped. Overrides uptime if both overlap.
cloudoff:ttl3d or 12h or 1wTime-to-live from instance launch. Supports h (hours), d (days), w (weeks).

*ttl starts counting from instance atttach time of first network insterface. If exceeded, the instance is considered expired and eligible for termination.
