You are building a Cisco Modeling Labs (CML) topology that a GitLab CI pipeline will start via the CML REST API before running automation tests. The tests require each router node to boot with a known baseline configuration (hostname, management IP, and NETCONF/RESTCONF enabled) so the pipeline can reach devices without an interactive console step. What is the correct way to ensure each node comes up with this baseline already applied when the lab is started programmatically?
