TL;DR: If you maintain VMware Cloud Foundation at scale, mapping clusters to custom ESXi ISOs by hand doesn’t scale. This post introduces a script that discovers your inventory, lets you pick an ESXi bundle, maps clusters to the right ISO (per‑vendor or per‑cluster), handles mixed‑vendor clusters by skipping non‑selected hosts, writes the JSON spec, and updates LCM properties and optionally restarts the LCM service for you.
Note: This script only works for vLCM Baseline/VUM mode clusters
Why this matters
SDDC Manager supports custom ESXi ISOs for patching/upgrades by pointing LCM at a JSON mapping (Bundle → Cluster → ISO) and setting a property in application-prod.properties. That’s fine for a handful of clusters. But with multiple domains, hundreds of clusters, and mixed hardware vendors, the manual workflow becomes slow and error‑prone.
What the script does
- Discovers inventory (domains, clusters, hosts) from SDDC Manager API.
- Lists ESXi bundles (
GET /v1/bundles?productType=ESX) and lets you pick one. - Lets you choose single ISO per vendor or per‑cluster ISO with cluster context in the prompt.
- For mixed‑vendor clusters, you choose which vendor to upgrade; other vendor hosts are added to skip list.
- Multiple ISOs cannot be mapped to a single cluster, a cluster with two vendors will have to be upgraded twice, once per vendor.
- With mixed-vendor clusters, the hosts that are not mapped to a custom ISO will be skipped.
- Generates
generated_custom_iso_spec.jsonwithesxCustomImageSpecListentries per cluster. - Updates LCM properties:
lcm.esx.upgrade.custom.image.spec=<absolute_path_to_generated_custom_iso_spec.json>esx.upgrade.skip.host.ids=<comma-separated-host-ids>(only when applicable)
- Prints a summary per vendor and an optional LCM restart prompt.
Requirements
- VUM/vLCM Baseline mode. vLCM Image mode is not supported.
- Run on SDDC Manager as root.
- Valid SSO credentials with permission to obtain a token.
- ISO files are present on disk and readable (e.g.
/nfs/vmware/vcf/nfs-mount/isos/*.iso).
Mixed‑vendor handling
What if my cluster has 3 Dell + 1 HPE host?
You choose Dell → the single HPE host is added to esx.upgrade.skip.host.ids. The console prints each skipped host as:
Hosts that will be skipped are:
– esxi-1.vrack.vsphere.local (HPE) in domain MGMT, cluster SDDC-Cluster1
If you choose HPE → the three Dell hosts are added to esx.upgrade.skip.host.ids. The console output would be:
Hosts that will be skipped are:
– esxi-2.vrack.vsphere.local (Dell) in domain MGMT, cluster SDDC-Cluster1
– esxi-3.vrack.vsphere.local (Dell) in domain MGMT, cluster SDDC-Cluster1
– esxi-4.vrack.vsphere.local (Dell) in domain MGMT, cluster SDDC-Cluster1
Clusters with multiple vendors will need to be updated multiple times
Usage
Help
python custom-cluster-with-domain.py -h
usage: cluster-iso-mapping.py [-h] [-a] [-d ]
VMware Cloud Foundation – Generate custom ISO spec for ESXi cluster upgrades
*** Note that this script only works for VUM/vLCM Baseline clusters. ***
options:
-h, --help show this help message and exit
-a, --all Automatically include all clusters in all domains
-d <domain name>, --domain <domain name>
Comma-separated domain name(s) to limit selection (works with --all or interactive mode)
-a, --allselect all clusters (optionally scope with--domain).-d, --domain domain— comma-separated domain names, e.g.--domain MGMT,sfo-w01(works in both modes).
Typical runs
Interactive across all domains (default)
python cluster-iso-mapping.py
- Prompts you to select domains, then lists clusters to pick.
Interactive for specific domains
python cluster-iso-mapping.py --domain MGMT,sfo-w01
- Only clusters from MGMT and sfo-w01 domains are offered.
All clusters across all domains
python cluster-iso-mapping.py --all
- Selects every cluster in every domain
All clusters for specific domains
python cluster-iso-mapping.py --all --domain MGMT,sfo-w01
- Selects every cluster only in the listed domains
Examples
In my environment, I have 6 workload domains (Management + 5 VI WLDs). Each VI WLD has 10 clusters with 10 hosts each.
I can also query the environment to see a list of vendors associated with each domain and each cluster.
Code Examples
Interactive across all domains, single iso per vendor
python cluster-iso-mapping.py
