    What's Changed

    Full Changelog: https://github.com/cloudymax/kubevirt-community-stack/compare/kubevirt-stack-0.3.0...cloud-init-3.0.0

    This version changes the way user passwords are discovered.

    In cloud-init, users are defined as as list: users[].

    Previously we had been discovering user passwords by looking for the env var ${USERNAME}_PASSWORD

    eg.

    extraEnvVars:
  - name: USERNAME
    value: friend
  - name: FRIEND_PASSWORD
     valueFrom:
       secretKeyRef:
         name: admin-password
         key: password

    but this made it difficult to obscure usernames for security purposes and was not very ergonomic when using list-generators in argocd to define multiple VMs with different users.

    eg.

    apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
  name: bastions-app-set
  namespace: argocd
  annotations:
    argocd.argoproj.io/sync-wave: "1"

spec:
  goTemplate: true
  generators:
    - list:
        elements:
          - vmName: vm0
            passwordSecret: user0-credentials

          - vmName: vm1
            passwordSecret: user1-credentials

    Now, we look for usernames and passwords according to the index in the users[] list.

    eg.

    extraEnvVars:
  - name: USER0_USERNAME
     valueFrom:
       secretKeyRef:
         name: '{{ .passwordSecret }}'         
         key: username
  - name: USER0_PASSWORD
     valueFrom:
       secretKeyRef:
         name: '{{ .passwordSecret }}' 
         key: password
