error finding network: %v

Error message

error finding network: %v

What it means

setupVPC (Openstack branch) wraps the error from finding the Openstack network matching the given subnet ID. It fires when the network query fails or the subnet's network cannot be located, so cluster.Spec.Networking.NetworkID cannot be populated.

Solutions

  1. Verify the subnet/network IDs exist in the OpenStack project
  2. Check Networking (Neutron) API access and quotas
  3. Pass the network ID explicitly via configuration options
Defensive patterns

Strategy: try-catch
