Public bug reported:
The script to convert nic config files from old-style to new-style will fail if
the the input yaml file has a blank like followed by a comment, like this:
-
type: vlan
vlan_id: {get_param: TenantNetworkVlanID}
addresses:
-
ip_netmask: {get_param: TenantIpSubnet}
# Uncomment when including environments/network-management.yaml
-
type: vlan
vlan_id: {get_param: ManagementNetworkVlanID}
addresses:
-
ip_netmask: {get_param: ManagementIpSubnet}
It will result in this error:
