About

Infra Field Notes is a collection of practical infrastructure notes based on real-world systems, migrations, incidents, and troubleshooting.

The focus is on infrastructure that small IT and DevOps teams actually run: Linux, Kubernetes and k3s, Proxmox, cloud platforms, CI/CD, networking, backup and disaster recovery.

Most articles on this site originate from real problems encountered while operating or migrating systems. Production-specific details such as customer names, domains, IP addresses, credentials, and internal network information are removed or changed before publication.

The goal is simple: document what worked, what failed, and what I would do differently next time.

Topics covered include:

  • Kubernetes and k3s
  • Proxmox and virtualization
  • Azure and cloud infrastructure
  • GitLab CI/CD and container deployments
  • Cloudflare and networking
  • Backup and disaster recovery
  • Linux and Windows troubleshooting

Infra Field Notes is independently maintained and is not affiliated with the vendors or products mentioned in its articles.
