ITNEXT·1yKubernetes Networking: Pod-to-Pod Communication
Kubernetes ensures each pod can communicate with any other pod in the cluster without Network Address Translation (NAT). This communication relies on CNI plugins like Kindnet to establish routing rules between nodes. Pods operate within isolated network namespaces connected to the host network via virtual Ethernet pairs. Intra-node communication happens at Layer 2, while inter-node communication is routed through physical interfaces using static routes. Each pod gets a unique IP address from a range allocated to its node, enabling direct communication within the cluster.
NetBox Labs·1yHow to Automate Proxmox Virtual Machine Configuration with NetBox and Ansible AWX/Tower/Automation Platform (AAP)
NetBox is a popular Network Source of Truth (NSoT) that can be integrated with Proxmox to automate and manage virtual machine (VM) states using Ansible AWX/Tower/Automation Platform (AAP). This integration leverages event-driven automation with webhooks and event rules in NetBox to trigger automated actions in Proxmox using predefined Ansible playbooks. Version 1.1.0 of netbox-proxmox-automation facilitates this setup, requiring a running AWX instance, defined projects, credentials, and job templates. Users must configure necessary scripts and settings to ensure seamless automation.
