# Salt Masterless Provisioner
Type: `salt-masterless`
The `salt-masterless` Terraform provisioner provisions machines built by Terraform
using [Salt ](http://saltstack.com/ ) states, without connecting to a Salt master. The `salt-masterless` provisioner supports `ssh` [connections ](/docs/provisioners/connection.html ).

-> **Note:** Provisioners should only be used as a last resort. For most
common situations there are better alternatives. For more information, see
[the main Provisioners page ](./ ).

## Requirements
The `salt-masterless` provisioner has some prerequisites. `cURL` must be available on the remote host.
## Example usage
The example below is fully functional.
```hcl
provisioner "salt-masterless" {
"local_state_tree" = "/srv/salt"
}
```
## Argument Reference
The reference of available configuration options is listed below. The only
required argument is the path to your local salt state tree.
Optional:
- `bootstrap_args` (string) - Arguments to send to the bootstrap script. Usage
is somewhat documented on
[github ](https://github.com/saltstack/salt-bootstrap ), but the [script
itself](https://github.com/saltstack/salt-bootstrap/blob/develop/bootstrap-salt.sh)
has more detailed usage instructions. By default, no arguments are sent to
the script.
- `disable_sudo` (boolean) - By default, the bootstrap install command is prefixed with `sudo` . When using a
Docker builder, you will likely want to pass `true` since `sudo` is often not pre-installed.
- `remote_pillar_roots` (string) - The path to your remote [pillar
roots](http://docs.saltstack.com/ref/configuration/master.html#pillar-configuration).
default: `/srv/pillar` . This option cannot be used with `minion_config` .
- `remote_state_tree` (string) - The path to your remote [state
tree](http://docs.saltstack.com/ref/states/highstate.html#the-salt-state-tree).
default: `/srv/salt` . This option cannot be used with `minion_config` .
- `local_pillar_roots` (string) - The path to your local [pillar
roots](http://docs.saltstack.com/ref/configuration/master.html#pillar-configuration).
This will be uploaded to the `remote_pillar_roots` on the remote.
- `local_state_tree` (string) - The path to your local [state
tree](http://docs.saltstack.com/ref/states/highstate.html#the-salt-state-tree).
This will be uploaded to the `remote_state_tree` on the remote.
- `custom_state` (string) - A state to be run instead of `state.highstate` .
Defaults to `state.highstate` if unspecified.

- `minion_config_file` (string) - The path to your local [minion config
2017-06-23 05:37:17 +02:00
file](http://docs.saltstack.com/ref/configuration/minion.html). This will be
uploaded to the `/etc/salt` on the remote. This option overrides the
`remote_state_tree` or `remote_pillar_roots` options.
- `skip_bootstrap` (boolean) - By default the salt provisioner runs [salt
bootstrap](https://github.com/saltstack/salt-bootstrap) to install salt. Set
this to true to skip this step.
- `temp_config_dir` (string) - Where your local state tree will be copied
before moving to the `/srv/salt` directory. Default is `/tmp/salt` .
- `no_exit_on_failure` (boolean) - Terraform will exit if the `salt-call` command
fails. Set this option to true to ignore Salt failures.
- `log_level` (string) - Set the logging level for the `salt-call` run.
- `salt_call_args` (string) - Additional arguments to pass directly to `salt-call` . See
[salt-call ](https://docs.saltstack.com/ref/cli/salt-call.html ) documentation for more
information. By default no additional arguments (besides the ones Terraform generates)
are passed to `salt-call` .
- `salt_bin_dir` (string) - Path to the `salt-call` executable. Useful if it is not
on the PATH.
