🚀 Welcome to Frikiteam Docs 🚀¶

Welcome to Frikiteam's technical documentation! I am a professional passionate about technology who shares knowledge and experiences in the world of infrastructure, cloud, and automation.

🎯 My Idea¶

My idea is to provide practical, clear, and useful documentation about the technologies I use daily. I want to share not only theory but also real experiences, tricks, and best practices I've learned in the technological "trenches."

🆕 Latest Updates¶

📅 August 3, 2026¶

🛡️ Linux operations: firewall, scripting and diagnosis (ES/EN)¶

nftables + fail2ban: a persistent ruleset and real integration — sets with expiry, a safety net so you don't lock yourself out, backend = systemd and banaction = nftables-* (the values in older guides leave the jail silently idle), the recidive jail and custom filters.
Bash and REST APIs: curl and jq without scripts that lie — separating body/status/network errors, exponential backoff, pagination, secrets off the command line and a tested service checker.
Terminal monitoring: btop, glances, ctop, lazydocker and k9s — how to read load average and PSI correctly, plus a diagnostic order for "the server is slow".

🐋 Podman Quadlet: containers as systemd services (ES/EN)¶

Quadlet: declaring containers as systemd units — .container/.volume/.network/.pod files, healthchecks with automatic restart, startup dependencies, auto-update with rollback and a translation table from Docker Compose.
Expands the Quadlet section of Rootless Podman, which now links here for the full lifecycle.

🚦 Traefik: dynamic reverse proxy (ES/EN)¶

Traefik: base guide to the reverse proxy with automatic discovery — static vs dynamic configuration, automatic HTTPS with Let's Encrypt (HTTP-01 and DNS-01 for wildcards), middlewares, secure dashboard and Prometheus metrics.
Rounds out the load-balancing section alongside HAProxy and the load balancer comparison, with explicit criteria for choosing between them.

📅 July 19, 2026¶

🔒 Cybersecurity: backup, incident response, compliance and offensive auditing (ES/EN)¶

Secure backup: encryption, immutability and restore testing against ransomware, with a restore-verification script.
Incident response: a practical playbook with TheHive and MISP following the NIST SP 800-61 lifecycle.
Compliance and auditing: GDPR, ISO 27001 and OpenSCAP as technical controls with reproducible evidence.
Applied cryptography: primitives, password hashing and key management, the conceptual companion to TLS and the existing VPN guides.
Basic pentesting: a methodology for auditing your own infrastructure with Nmap, Burp Suite and Metasploit, framed around authorization and legal scope.

🤖 LLMs in production: Kubernetes, observability and cost (ES/EN)¶

LLMs on Kubernetes: GitOps deployment with Helm and ArgoCD, plus three reliability fixes to the existing deployment guide (startupProbe, HPA on vLLM metrics, secrets management).
LLM monitoring: inference observability covering TTFT/TPOT, KV cache saturation and verified vLLM metrics.
Open-source vs cloud: cost, latency, privacy and control, using this repo's own multi-server inference pipeline as a real case study.

🐳 Containers and databases (ES/EN)¶

Rootless Podman: containers without a daemon or root, threat model versus Docker and a practical migration path.
PostgreSQL High Availability: replication, Patroni and tested failover, expanding the HA section of the base PostgreSQL guide.

📅 July 18, 2026¶

🤖 Complete local LLM ecosystem (ES/EN)¶

Inference engines: LLaMA.cpp (build, GGUF quantization and benchmarking), LM Studio (graphical interface) and vLLM (serving at scale with high throughput).
Unified gateway: LiteLLM as a single OpenAI-compatible layer in front of local models and cloud providers, with budget control and fallbacks.
Distributed inference: MeshLLM, a P2P mesh that pools GPUs from several machines behind a single endpoint.
MCP protocol: MCP and FastMCP integrated into the navigation.

🔒 Security: runtime, IaC and GitOps (ES/EN)¶

Container isolation: Docker Runtime Security with gVisor and Kata Containers, complementing image hardening.
Infrastructure as Code: IaC Security with Checkov and TFLint, integrated into pre-commit and CI/CD.
Versioned secrets: Secrets in GitOps comparing SOPS, Sealed Secrets and External Secrets Operator.

☸️ Kubernetes and storage (ES/EN)¶

Service Mesh: Istio vs Linkerd vs Cilium comparison, including an honest section on when you don't need a service mesh.
Persistent storage: Kubernetes Storage comparing Ceph RBD, Longhorn and OpenEBS, with a reproducible benchmark methodology.

📅 April 18, 2026¶

🌐 New vRouters section (ES/EN)¶

Overview: new guide on vRouters and virtual firewalls with selection criteria.
Platform guides: specific documentation for OPNsense, pfSense, MikroTik CHR and VyOS.
Performance testing: new reusable template with KPIs, per-environment profiles and acceptance criteria.
Language parity: equivalent content also available in English under en/doc/networking/.

📅 January 25, 2026¶

🚀 Complete OpenStack + Ceph documentation¶

New deployment guide: Deployment with Kolla-Ansible - Full OpenStack installation in production
Storage integration: OpenStack + Ceph - Ceph backend for Glance, Cinder and Nova
Advanced troubleshooting: OpenStack issues and Ceph issues
Production operations: Day-2 Operations expanded with upgrades, backups, monitoring and DR

📊 Privacy-friendly analytics¶

Plausible Analytics: complete self-hosting guide (GDPR-compliant, cookie-free)
Log script: access analysis to monitor without invasive tracking
Ready-made configuration: MkDocs prepared to integrate analytics when deployed

🔧 Maintainability improvements¶

Freshness tracking: script that detects stale documentation (>90 days)
Simplified checklist: contribution guide updated with 5 essential points
Improvement roadmap: TODO.md with a practical maintainability plan

🤖 Artificial Intelligence section¶

LLM fundamentals: complete introduction to language models
Ollama: practical guide to local AI
Models and evaluation: benchmarking and model comparison

📅 January 24, 2026¶

Full ES/EN parity: translation of 40+ critical files (Kubernetes, Docker, networking, cybersecurity)
New AI documentation: local ecosystems, RAG, vector databases
Storage improvements: PostgreSQL + Ceph, Pure Storage, NetApp

📅 January 23, 2026¶

Blog reorganization: technical posts moved to drafts for publication on WordPress
i18n link fixes: symmetric Spanish/English navigation
Build validation: clean MkDocs build with no errors
