# local-exec Provisioner
The `local-exec` provisioner invokes a local executable after a resource
is created. This invokes a process on the machine running Terraform, not on
the resource. See the `remote-exec` [provisioner](/docs/provisioners/remote-exec.html)
to run commands on the resource.
## Example usage
```
# Join the newly created machine to our Consul cluster
resource "aws_instance" "web" {
...
provisioner "local-exec" {
command = "consul join ${aws_instance.web.private_ip}"
}
}
```
## Argument Reference
The following arugments are supported:
* `command` - (Required) This is the command to execute. It can be provided
as a relative path to the current working directory or as an absolute path.
It is evaluated in a shell, and can use environment variables or Terraform
variables.
