Terraform : remote_exec

  1. Connection sur le remote server ensuite installation de nginx:

Les provisionneurs peuvent être utilisés pour modéliser des actions spécifiques sur la machine locale ou sur une machine distante afin de préparer des serveurs ou d’autres objets d’infrastructure pour le service.

variable “ssh_host” {}
variable “ssh_user” {}
variable “ssh_key” {}
resource “null_resource” “ssh_target” {
connection {
type = “ssh”
user = var.ssh_user
host = var.ssh_host
private_key = file(var.ssh_key)}
provisioner “remote-exec” {
inline = [
“sudo apt update -qq >/dev/null”,
“sudo apt install -qq -y nginx >/dev/null”
]
}
}
