Prepare templates for cloud-init

...

For VMware (vCenter hosts, vCenter clusters, VCD) and other private cloud hypervisors, where cloud-init uses a configuration drive, you might need to prepare the operating system of your VM templates for this configuration.

  1. Edit the cloud config installer file. The location of this file will vary by operating system. For example, /etc/cloud/cloud.conf.d/99-installer.cfg. Set the datasource to ConfigDrive as shown here.

    Code Block
    datasource:
  ConfigDrive:
datasource_list: [ConfigDrive]

  2. In the case of Ubuntu 18+, disable any default network configuration utility.

    1. Remove /etc/cloud/cloud.conf.d/subiquity-disable-cloudinit-networking.cfg

    2. Remove /etc/netplan/00-installer-config.yml
