Treat network config like code: review in merge requests, validate offline with Batfish, push with a diff gate, and roll back on failure. A GitLab pipeline that turns "SSH in and paste" into a reviewable, reversible process.
SNMP polls; gNMI streams. How model-driven telemetry with gNMI subscriptions, gnmic, and OpenConfig paths replaces the poll-and-pray loop, and how to land the data in Prometheus without writing a collector.
A source of truth only earns the name when config is generated from it, not typed beside it. Modeling your network in NetBox, pulling it with pynetbox, and using it as a dynamic inventory so the database and the devices cannot drift.
When Ansible YAML stops scaling, Python automation takes over. How Nornir handles inventory and concurrency, NAPALM abstracts vendor CLIs, and the two combine into config push with diffs and rollback.
A practical guide to automating network infrastructure using Ansible. Real examples from production environments including device configuration, backup strategies, and compliance checking.
Practical VyOS automation with Git, templates, and safe deployment practices. Covers config backup strategies, Jinja2 templates, Ansible integration, rollback procedures, and why automation reduces errors only if you have rules of the game.
Reliable IP address management for Proxmox VMs. Covers DHCP strategies, MAC-to-IP mapping, router integrations, inventory collection, and why IP addresses are data that must be collected automatically.
Automated VM template creation for Proxmox. Covers Packer integration, cloud-init pipelines, image versioning, testing, and why images must be reproducible or they become unique snowflakes.
Terraform with Proxmox done right. Covers provider configuration, module structure, state management, safe changes, and why IaC is about predictability, not faster clicking.
Building secure multi-tenant Proxmox environments. Covers RBAC configuration, resource pools, API token management, audit logging, and why access control is a product that requires design.
Creating and using VM templates with cloud-init on Proxmox. Covers template creation workflow, cloud-init configuration, customization, and why a template is a contract that must stay stable.
