How to change the Internal Docker subnet for License Server in VCF 9.1

Products

• VCF Operations

Issue/Introduction

This article provides the steps to change the internal Docker subnet configuration for the License Server component in VMware Cloud Foundation (VCF).

Environment

VMware Operations 9.1.0
License Server 9.1.0

Cause

The default internal Docker network pool requires modification to accommodate a custom network range via vCenter Advanced Parameters.

Resolution

Please follow the below steps to change the Docker internal IP:

1. Verify that the VCF Operations and License Server components are running on version 9.1.0.0400 or above

2. Power off the License Server Virtual Machine (VM) in vCenter.

3. Navigate to the VM Settings and access Advanced Parameters.

4. Add the following parameter:

   • Key: guestinfo.ls.docker.pool

   • Value: xxx.xxx.0.0/xx (or substitute with another valid network range as required)

5. Power on the VM.

Additional Information

In version 9.1.0.0400, non-external IP addresses were removed from the vCenter console. The network configuration will be honored exactly as configured, but the docker IP address will be missing from the vCenter display.
