- `winrm_username` (string) - The username to use to connect to WinRM. - `winrm_password` (string) - The password to use to connect to WinRM. - `winrm_host` (string) - The address for WinRM to connect to. NOTE: If using an Amazon EBS builder, you can specify the interface WinRM connects to via [`ssh_interface`](/docs/builders/amazon-ebs#ssh_interface) - `winrm_port` (int) - The WinRM port to connect to. This defaults to `5985` for plain unencrypted connection and `5986` for SSL when `winrm_use_ssl` is set to true. - `winrm_timeout` (duration string | ex: "1h5m2s") - The amount of time to wait for WinRM to become available. This defaults to `30m` since setting up a Windows machine generally takes a long time. - `winrm_use_ssl` (bool) - If `true`, use HTTPS for WinRM. - `winrm_insecure` (bool) - If `true`, do not check server certificate chain and host name. - `winrm_use_ntlm` (bool) - If `true`, NTLMv2 authentication (with session security) will be used for WinRM, rather than default (basic authentication), removing the requirement for basic authentication to be enabled within the target guest.
