Подготовка Consul

Есть разные способы - тут привожу пример с использованием терраформ

• Требуется токен (получение токена - https://noname.com.ua/mediawiki/index.php/Consul_Basic_Setup#management_token )
• токен приведен для примера

export CONSUL_TOKEN="4f6037ed-5f62-5463-d165-cbb984791ef1"

• Установить терраформ (если не установлен)

apt install terraform

cat acl.tf

variable "consul_datacenter" {

   type = string
   default = "kilda-fred"

} provider "consul" {

 address    = "http://127.0.0.1:8500"
