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.

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.
