Bulk Import vSphere dvPortGroups to phpIPAM 2022-02-04 I wrote a Python script to interface with the phpIPAM API and import a large number of networks exported from vSphere for IP management. false false true true code.png false Scripts

I recently wrote about getting started with VMware's Tanzu Community Edition and deploying phpIPAM as my first real-world Kubernetes workload. Well I've spent much of my time since then working on a script which would help to populate my phpIPAM instance with a list of networks to monitor.

Planning and Exporting

The first step in making this work was to figure out which networks I wanted to import. We've got hundreds of different networks in use across our production vSphere environments. I focused only on those which are portgroups on distributed virtual switches since those configurations are pretty standardized (being vCenter constructs instead of configured on individual hosts). These dvPortGroups bear a naming standard which conveys all sorts of useful information, and it's easy and safe to rename any dvPortGroups which don't fit the standard (unlike renaming portgroups on a standard virtual switch).

The standard naming convention is [Site/Description] [Network Address]{/[Mask]}. So the networks (across two virtual datacenters and two dvSwitches) look something like this: Production dvPortGroups approximated in my testing lab environment

Some networks have masks in the name, some don't; and some use an underscore (_) rather than a slash (/) to separate the network from the mask . Most networks correctly include the network address with a 0 in the last octet, but some use an x instead. And the VLANs associated with the networks have a varying number of digits. Consistency can be difficult so these are all things that I had to keep in mind as I worked on a solution which would make a true best effort at importing all of these.

As long as the dvPortGroup names stick to this format I can parse the name to come up with a description as well as the IP space of the network. The dvPortGroup also carries information about the associated VLAN, which is useful information to have. And I can easily export this information with a simple PowerCLI query:

PS /home/john> get-vdportgroup | select Name, VlanConfiguration

Name                           VlanConfiguration
----                           -----------------
MGT-Home 192.168.1.0
MGT-Servers 172.16.10.0        VLAN 1610
BOW-Servers 172.16.20.0        VLAN 1620
BOW-Servers 172.16.30.0        VLAN 1630
BOW-Servers 172.16.40.0        VLAN 1640
DRE-Servers 172.16.50.0        VLAN 1650
DRE-Servers 172.16.60.x        VLAN 1660
VPOT8-Mgmt 172.20.10.0/27      VLAN 20
VPOT8-Servers 172.20.10.32/27  VLAN 30
VPOT8-Servers 172.20.10.64_26  VLAN 40

In my homelab, I only have a single vCenter. In production, we've got a handful of vCenters, and each manages the hosts in a given region. So I can use information about which vCenter hosts a dvPortGroup to figure out which region a network is in. When I import this data into phpIPAM, I can use the vCenter name to assign remote scan agents to networks based on the region that they're in. I can also grab information about which virtual datacenter a dvPortGroup lives in, which I'll use for grouping networks into sites or sections.

The vCenter can be found in the Uid property returned by get-vdportgroup:

PS /home/john> get-vdportgroup | select Name, VlanConfiguration, Datacenter, Uid

Name                     VlanConfiguration   Datacenter Uid
----                     -----------------   ---------- ---
MGT-Home 192.168.1.0                         Lab        /VIServer=lab\john@vcsa.lab.bowdre.net:443/DistributedPortgroup=DistributedVirtualPortgroup-dvportgroup-27015/

It's not pretty, but it'll do the trick. All that's left is to export this data into a handy-dandy CSV-formatted file that I can easily parse for import:

get-vdportgroup | select Name, VlanConfiguration, Datacenter, Uid | export-csv -NoTypeInformation ./networks.csv

My networks.csv export, including the networks which don't match the naming criteria and will be skipped by the import process.

Setting up phpIPAM

After deploying a fresh phpIPAM instance on my Tanzu Community Edition Kubernetes cluster, there are a few additional steps needed to enable API access. To start, I log in to my phpIPAM instance and navigate to the Administration > Server Management > phpIPAM Settings page, where I enabled both the Prettify links and API feature settings - making sure to hit the Save button at the bottom of the page once I do so. Enabling the API

Then I need to head to the User Management page to create a new user that will be used to authenticate against the API: New user creation

And finally, I head to the API section to create a new API key with Read/Write permissions: API key creation

I'm also going to head in to Administration > IP Related Management > Sections and delete the default sample sections so that the inventory will be nice and empty: We don't need no stinkin' sections!

Well that's enough prep work; now it's time for the Python3 script:

I'll run it and provide the path to the network export CSV file:

python3 phpipam-bulk-import.py ~/networks.csv

The script will print out a little descriptive bit about what sort of networks it's going to try to import and then will straight away start processing the file to identify the networks, vCenters, VLANs, and datacenters which will be imported:

Importing networks from /home/john/networks.csv...
Processed 17 lines and found:

- 10 networks:
        ['BOW-Servers 172.16.20.0', 'BOW-Servers 172.16.30.0', 'BOW-Servers 172.16.40.0', 'DRE-Servers 172.16.50.0', 'DRE-Servers 172.16.60.x', 'MGT-Home 192.168.1.0', 'MGT-Servers 172.16.10.0', 'VPOT8-Mgmt 172.20.10.0/27', 'VPOT8-Servers 172.20.10.32/27', 'VPOT8-Servers 172.20.10.64_26']

        [0, 20, 30, 40, 1610, 1620, 1630, 1640, 1650, 1660]

- 2 Datacenters:
        ['Lab', 'Other Lab']

It then starts prompting for the additional details which will be needed:

Region name for vCenter vcsa:
Labby

Comma-separated list of nameserver IPs in Lab vCenter:

Fully-qualified domain name of the phpIPAM host:

api-user

Use per-region remote scan agents instead of a single local scanner? (y/N):
y

Up to this point, the script has only been processing data locally, getting things ready for talking to the phpIPAM API. But now, it prompts to confirm that we actually want to do the thing (yes please) and then gets to work:

[FINISH] Created 10 of 10 networks.

Success! Now I can log in to my phpIPAM instance and check out my newly-imported subnets: New subnets!

Even the one with the weird name formatting was parsed and imported correctly: Subnet details

So now phpIPAM knows about the vSphere networks I care about, and it can keep track of which vLAN and nameservers go with which networks. Great! But it still isn't scanning or monitoring those networks, even though I told the script that I wanted to use a remote scan agent. And I can check in the Administration > Server management > Scan agents section of the phpIPAM interface to see my newly-created agent configuration. New agent config

... but I haven't actually deployed an agent yet. I'll do that by following the same basic steps described here to spin up my phpipam-agent on Kubernetes, and I'll plug in that automagically-generated code for the IPAM_AGENT_KEY environment variable:

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: phpipam-agent
spec:
  selector:
    matchLabels:
      app: phpipam-agent

        env:
        - name: IPAM_DATABASE_HOST
          value: "ipam-k8s.lab.bowdre.net"
        - name: IPAM_DATABASE_NAME
          value: "phpipam"
        - name: IPAM_DATABASE_USER
          value: "phpipam"
        - name: IPAM_DATABASE_PASS
          value: "VMware1!"
        - name: IPAM_DATABASE_PORT
          value: "3306"
        - name: IPAM_AGENT_KEY
          value: "CxtRbR81r1ojVL2epG90JaShxIUBl0bT"
        - name: IPAM_SCAN_INTERVAL
          value: "15m"
        - name: IPAM_RESET_AUTODISCOVER
          value: "false"
        - name: IPAM_REMOVE_DHCP
          value: "false"
        - name: TZ
          value: "UTC"

I kick it off with a kubectl apply command and check back a few minutes later (after the 15-minute interval defined in the above YAML) to see that it worked, the remote agent scanned like it was supposed to and is reporting IP status back to the phpIPAM database server: Newly-discovered IPs

I think I've got some more tweaks to do with this environment (why isn't phpIPAM resolving hostnames despite the correct DNS servers getting configured?) but this at least demonstrates a successful proof-of-concept import thanks to my Python script. Sure, I only imported 10 networks here, but I feel like I'm ready to process the several hundred which are available in our production environment now.

And who knows, maybe this script will come in handy for someone else. Until next time!
