kubespray-lab-setup

The code fragment can provision a local Kubespray lab but uses high-risk security patterns unsuitable for anything beyond an isolated lab. Hardcoded credentials, root SSH access with password authentication, and unverified external downloads create substantial risk for credential exposure and supply-chain integrity. To improve security, replace plaintext credentials with ephemeral or vaulted credentials, disable password-based SSH in production-like contexts, pin and verify external artifacts (checksums/signatures), enable appropriate firewall/SELinux policies, and implement least-privilege access controls. Given these improvements, the footprint would still be acceptable for a controlled lab but would no longer resemble best practices for secure distribution of infrastructure tooling.
