Valid variables to request are: "ID", "Host",
"Port", "User", "Password", "ConnType",
"PackerRunUUID", "PackerHTTPAddr", "SSHPublicKey", and "SSHPrivateKey".
Depending on which communicator you are using, some of these values may be
empty -- for example, the public and private keys are unique to the SSH
communicator. InstanceID represents the vm being provisioned. For example,
in Amazon it is the instance id; in digitalocean, it is the droplet id; in
Vmware, it is the vm name.
Valid variables to request are:
- __ID__: Represents the vm being provisioned. For example, in Amazon it is the instance id; in digitalocean,
it is the droplet id; in Vmware, it is the vm name.
- __Host__, __Port__, __User__ and __Password__: The host, port, user, and password that Packer uses to access the machine.
Useful for using the shell local provisioner to run Ansible or Inspec against the provisioned instance.
- __ConnType__: Type of communicator being used. For example, for SSH communicator this will be "ssh".
- __PackerRunUUID__: Current build's unique id. Can be used to specify build artifacts.
- __PackerHTTPAddr__: HTTP address of the file server Packer creates to serve items in the "http" dir to the vm, displayed in the format `IP:PORT`.
- __SSHPublicKey__ and __SSHPrivateKey__: The public and private key that Packer uses to connect to the instance.
These are unique to the SSH communicator and are unset when using other communicators.
__SSHPublicKey__ and __SSHPrivateKey__ can have escape sequences and special characters so their output should be single quoted to avoid surprises. For example:
```
{
...
"provisioners": [
{
"type": "shell",
"inline": [
"echo '{{ build `SSHPrivateKey`}}' > /tmp/packer-session.pem"
]
}
]
}
```
For backwards compatability, `WinRMPassword` is also available through this
engine, though it is no different than using the more general `Password`.
