Preflight Check

Preflight

Initial system validation before bootstrapping. Checks root, deps (curl/bash), internet, OS (Ubuntu/Linux Mint), arch (x86_64/amd64). Fails fast if not ready.

Lab Environment Only

This tool is intended for ephemeral, short-lived lab environments and is not hardened for production use.

System Requirements

This script is designed for Ubuntu LTS and derivatives (Linux Mint, Pop!_OS). Other distributions (RHEL, Fedora, Debian, ARM) are not supported.

Installation Command

curl -sL https://raw.githubusercontent.com/ibtisam-iq/infra-bootstrap/main/scripts/system-checks/preflight.sh | sudo bash

What It Verifies

  • Root privileges.
  • curl/bash installed.
  • Internet (ping 8.8.8.8).
  • OS compatibility.
  • Architecture, hardware, virtualization and systemd check.
