# 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).
Fix docs for 0.15 for vendor provisioners

!> **Note:** This provisioner was removed in the 0.15.0 version of Terraform after being deprecated as of Terraform 0.13.4. For most common situations there are better alternatives to using provisioners. For more information, see [the main Provisioners page](./).
website: Warn against using provisioners For a long time now we've been advising against the use of provisioners, but our documentation for them is pretty prominent on the website in comparision to the better alternatives, and so it's little surprise that many users end up making significant use of them. Although in the longer term a change to our information architecture would probably address this even better, this is an attempt to be explicit about the downsides of using provisioners and to prominently describe the alternatives that are available for common use-cases, along with some reasons why we consider them to be better. I took the unusual step here of directly linking to specific provider documentation pages about the alternatives, even though we normally try to keep the core documentation provider-agnostic, because otherwise that information tends to be rather buried in the provider documentation and thus the reader would be reasonable to use provisioners just because we're not giving specific enough alternative recommendations.

## 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.
provisioner/salt-masterless: add "_file" suffix to "minion_config" In #15870 we got good feedback that it'd be more useful to have the various filename-accepting arguments on this provisioner instead accept strings that represent the contents of such files, so that they can be generated from elsewhere in the Terraform config. This change does not achieve that, but it does make room for doing this later by renaming "minion_config" to "minion_config_file" so that we can later add a "minion_config" option alongside that takes the file content, and deprecate "minion_config_file". Ideally we'd just implement the requested change immediately, but unfortunately the release schedule doesn't have time for this so this is a pragmatic change to allow us to make the full requested change at a later date without backward incompatibilities. This change is safe because the salt-masterless provisioner has not yet been included in a release at the time of this commit.

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.
