Hi, I have built a Nano server using cloudbase-init-offline-install and used that image in Ironic (Bifrost).

.\NewNanoServerImage.ps1 -IsoPath $isoPath -TargetPath $targetPath -AdministratorPassword $password -Platform "BareMetal" -Compute -Clustering -AddCloudbaseinit

The newly populated server don't get the metadata from configdrive. I have set the networking manually and used PowerShell to connect to the server. I see there is a Cloudbase-Init folder and all it's content, but: 1. Get-PSDrive don't show any extra partition with meta-data 2. Get-Service don't show any service related to cloudbase-init 3. C:\Cloudbase-init\logs are empty (never run?)

For the moment, can you try generating the image with .\NewNanoServerImage.ps1 -IsoPath $isoPath -TargetPath $targetPath -AdministratorPassword $password -Platform "BareMetal" -Compute -Clustering -AddCloudbaseinit -CloudbaseInitCOMPort $null ?

Thank you,
Adrian vladu

Now I can see Cloudbase-init execution from logs. Server did get the hostname from configdrive, but no network. Here is the log from cloudbase-init.log

Here is the configdrive structure:


Here is the content of networkinfo.json. networkdata.json is the same as network_info.json

"links": [
        "ethernet_mac_address": "0c:c4:7a:8e:0a:c4", 
        "id": "0c:c4:7a:8e:0a:c4", 
        "mtu": "1500", 
        "type": "phy"
"networks": [
        "dns_nameservers": [
        "id": "ipv4-0c:c4:7a:8e:0a:c4", 
        "ip_address": "", 
        "link": "0c:c4:7a:8e:0a:c4", 
        "netmask": "", 
        "routes": [
                "gateway": "", 
                "netmask": "", 
                "network": ""
        "type": "ipv4"
"services": [
        "address": "", 
        "type": "dns"

Make sure your environment is clean, as per the cloudbase-init log you provided, cloudbase-init already ran: Plugin 'NetworkConfigPlugin' execution already done, skipping To cleanup the environment, you can run from powershell: Remove-Item -Recurse "'HKLM:\SOFTWARE\Cloudbase Solutions\'"

I have done many clean installation, but nevertheless I could not make the Cloudbase-init to read network_data.json. Here is the log output from another "clean" run - I see NetworkConfigPlugin executed, read openstack/latest/meta_data.json but no network.

Got it. For the moment, we are working on adding support for the network_data.json file. currently, cloudbase-init supports only the debian like network information. Here is information you need to enable it:

Hello, Can you try with a non-production version of cloudbase-init zip, where the network_data.json support is implemented? You can use a local cloudbase-init zip path with the -CloudbaseInitZipPath param. I will add the link in the next comment.
