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 to run commands on the resource.

Beware that even though the resource is fully created when the provisioner is run, it doesn't need to have finished booting or starting system services.

Example usage

# Join the newly created machine to our Consul cluster
resource "aws_instance" "web" {
    ...
    provisioner "local-exec" {
        command = "echo ${aws_instance.web.private_ip} >> private_ips.txt"
    }
}

Argument Reference

The following arguments 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.
