EVE IaC

Your lab becomes code

topology.yml is a portable, reviewable description of the lab — nodes, networks, links, configuration and intent. Interface names in this example come from the IOL and VPCS templates; confirm them on yours before you copy them. YAML

version: eve-iac/v1
name: iol-vpcs-minimal
nodes:
  n_1:
    name: SW1
    template: iol
    configset: default
  n_2:
    name: PC1
    template: vpcs
    configset: default
links:
  - endpoints:
      - { node: n_1, interface: e0/0 }
      - { node: n_2, interface: eth0 }

Diff it. Review it. Commit it. Reconcile it.

eve-iac plan ./lab prints one status line. eve-iac plan ./lab --json includes text, which the agent formats like the listing below. These rows illustrate a create and a change that must stop a running node. They are not a captured transcript. Plan / reconcile
