packer - using different communicator credentials in a provisioner

[Frank.Lapierre]

Hi All,

I'm trying to fully automate a Windows 10 build using Packer. I'm mostly successful, with the exception of patching the OS before I generate the AMI/VM template.

I don't know if that's feasible or how to approach this, but here's what I'm trying:

1. Use specific WINRM credentials before my VM is joined to the domain.

2. After it is joined to the domain, use new credentials to keep interacting with the VM.

Since I can't specify a different communicator within the "provisioners" block, I'm not sure how I could do this? Reason I need to join the domain is because windows won't patch if it is not activated.

Invalid example (as I specified communicator info in the provisioner):

builder:

...

      "communicator": "winrm",

      "winrm_use_ssl": true,

      "winrm_insecure": true,

      "winrm_use_ntlm": true,

      "winrm_username": "Administrator",

      "winrm_password": "Password1",

...

  "provisioners": [

    {

      "type": "powershell",

      "environment_vars": [

        "vm_hostname={{user `vm_hostname`}}"

      ],

      "inline": ["Rename-Computer -NewName \"$env:vm_hostname\""]

    },

    { "type": "windows-restart",

      "pause_before": "30s"

    },

    {

      "type": "powershell",

      "script": "{{template_dir}}/join-domain.ps1",

      "environment_vars": [

        "vm_hostname={{user `vm_hostname`}}",

        "ad_domain={{user `ad_domain`}}",

        "ad_ou_path={{user `ad_ou_path`}}",

        "ad_domain_user=DOMAIN\\user",

        "ad_domain_pw=DOMAIN\\password"

      ]

    }

  ],

    "provisioners": [

    {

      "communicator": "winrm",

      "winrm_use_ssl": true,

      "winrm_insecure": true,

      "winrm_use_ntlm": true,

      "winrm_username": "{{ user `ad_username` }}",

      "winrm_password": "{{ user `ad_password` }}",

      "type": "windows-restart",

      "pause_before": "30s"

    }

  ]

}

Thanks!

We have a known issue with domain-joins not working because they mess up Packer's connection, but I haven't had a chance to investigate. Sorry :(
