Remote-Exec Provisioner

The remote-exec provisioner invokes a script on a remote resource after it is created. This can be used to run a configuration management tool, bootstrap into a cluster, etc. The remote-exec provisioner supports both ssh and winrm type connections.

# creating instance.
resource "aws_instance" "web" {
  ami                    = data.aws_ami.ubuntu.id
  instance_type          = var.instance_type
  key_name               = aws_key_pair.key-tf.key_name
  vpc_security_group_ids = ["${aws_security_group.allow_tls.id}"]
  tags = {
    Name = "first-tf-instance"
  }
  user_data = file("${path.module}/script.sh")
  connection {
    type        = "ssh"
    user        = "ubuntu"
    private_key = file("${path.module}/id_rsa")
    host        = self.public_ip
  }
  provisioner "remote-exec" {
    inline = [
      "ifconfig > /tmp/ifconfig.output",
      "echo 'hello gaurav'>/tmp/test.txt"
    ]
  }
  provisioner "remote-exec" {
    script = "./testscript.sh"
  }
}
