Deploy a VM With Cloud-Init

Cloud-Init is widely recognized as the de facto method for bootstrapping modern workloads on hyperscalers, including VM Service on vSphere.

Example

The example below illustrates a VirtualMachine resource that specifies a Cloud-Init Cloud Config via a Secret resource (my-vm-bootstrap-data).

apiVersion: vmoperator.vmware.com/v1alpha3
kind: VirtualMachine
metadata:
  name:      my-vm
  namespace: my-namespace
spec:
  className:    my-vm-class
  imageName:    vmi-0a0044d7c690bcbea
  storageClass: my-storage-class
  bootstrap:
    cloudInit:
      cloudConfig:
        users:
        - name: jdoe
          primary_group: jdoe
          groups: users
          passwd:
            name: my-vm-bootstrap-data
            key:  jdoe-passwd
          ssh_authorized_keys:
          - ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDSL7uWGj...
        runcmd:
        - "ls /"
        - [ "ls", "-a", "-l", "/" ]
        write_files:
        - path: /etc/my-plain-text
          permissions: '0644'
          owner: root:root
          content: |
            Hello, world.
        - path: /etc/my-secret-data
          permissions: '0644'
          owner: root:root
          content:
            name: my-vm-bootstrap-data
            key:  etc-my-secret-data

apiVersion: v1
kind: Secret
metadata:
  name:      my-vm-bootstrap-data
  namespace: my-namespace
stringData:
  jdoe-passwd: my-password
  etc-my-secret-data: |
    My super secret message.
