Nomad 0.12 introduces significant networking improvements, including multi-interface networking and CNI plugin support, which allows cluster administrators to define CNI plugins available on a node for job authors to use, and enables the selection of which network a job requires. This feature is useful in cases such as ingress services that route traffic from the public Internet to internal services, where multiple logical networking interfaces can be utilized. The improvements also address security concerns with host networking and task driver-based workarounds, allowing Nomad to enforce more secure networking configurations. Existing clusters and workloads will continue to function as usual, and cluster administrators can leverage these new features to enhance network configuration options for job authors.
