3. OAI Core Network Deployment

  • Target OS
    • Ubuntu 18.04 (bionic) server edition
    • Red Hat Entreprise Linux 8
  • Hardware Requirements
    • x86-64 Intel/AMD CPU
    • At least one 1 network device
  • Linux Kernel
    • Generic kernel is enough
  • Deployment feasible on:
    • PC
    • Server
    • Container
    • Virtual Machine

We strongly recommend a container-based deployment (either in a docker-compose fashion, or in a Kubernetes-like cluster).
