描述

我们将看到如何通过名为 "Terraform "的基础设施即代码工具快速部署一个或多个IKOULA One云实例。

首先，你需要安装Terraform，如果你还没有这样做，并且有一个IKOULA One Cloud账户。 Terraform可用于大多数操作系统，链接如下。 https://www.terraform.io/downloads.html

Terraform支持几十个供应商，其清单可在其网站上找到(https://www.terraform.io/docs/providers/). 我们将使用 "Cloudstack "供应商，在Cloud Ikoula One上进行部署。


部署单一实例

我们将编写我们的第一个Terraform配置文件，允许部署一个单一的IKOULA云实例。

这是一个扩展名为".tf "的文本文件（注意不要在你的工作目录中创建多个".tf "文件，否则Terraform会将它们全部载入），我们将使用经典的Terraform格式，但也可以使用JSON语法。

这里是我们的Terraform文件的内容，可以用你自己的参数进行调整。


对于在基本区域部署一个实例， 。 

provider "cloudstack" {
  api_url   = "https://cloudstack.ikoula.com/client/api"
  api_key    = "< Votre clé API de votre compte/utilisateur Cloud Ikoula One  >"
  secret_key = "< Votre clé secrète de votre compte/utilisateur Cloud Ikoula One>"
}

resource "cloudstack_instance" "< Nom de votre choix pour votre ressource >" {
  zone = "< Nom de la zone basic Cloud Ikoula One de votre choix >"
  service_offering = "< Nom de l'offre de calcul Cloud Ikoula One de votre choix > "
  template = "< Nom du modèle Cloud Ikoula One de votre choix"
  name = "< Nom de votre choix pour votre instance Cloud Ikoula One"
  keypair = "< Nom de votre paire de clé SSH Cloud Ikoula One>"
  expunge = "true"
  security_group_ids = ["< ID de votre groupe de sécurité Cloud Ikoula One à utiliser >",]
}


  • Pour le déploiement d'une instance en zone avancée (avec création d'une règle de redirection de port, pour ssh dans cet exemple) :
provider "cloudstack" {
  api_url   = "https://cloudstack.ikoula.com/client/api"
  api_key    = "< Votre clé API de votre compte/utilisateur Cloud Ikoula One  >"
  secret_key = "< Votre clé secrète de votre compte/utilisateur Cloud Ikoula One>"
}

resource "cloudstack_instance" "< Nom de votre choix pour votre ressource d'instance >" {
  zone = "< Nom de la zone avancée/adv Cloud Ikoula One de votre choix >"
  service_offering = "< Nom de l'offre de calcul Cloud Ikoula One de votre choix > "
  template = "< Nom du modèle Cloud Ikoula One de votre choix"
  name = "< Nom de votre choix pour votre instance Cloud Ikoula One"
  keypair = "< Nom de votre paire de clé SSH Cloud Ikoula One>"
  expunge = "true"
  network_id = ["< ID de votre réseau d'invités Cloud Ikoula One à utiliser >",]
}

# Redirection de port (ici SSH)

resource "cloudstack_port_forward" "SshTerraformVM1" {
  ip_address_id = "< ID de l'adresse ip NAT Source de votre réseau d'invités >"
  forward {
    protocol     = "tcp"
    private_port = "22"
    public_port  = "< port ssh publique de votre choix>"
    virtual_machine_id = "${cloudstack_instance.< Nom que vous avez choisis au-dessus pour votre ressource d'instance >.id}"
  }
}

Note : la ligne 'expunge = "true"' nous permettra de supprimer notre instance lors de l'appel "terraform destroy".


Une fois votre fichier de configuration enregistré, nous allons initialiser Terraform puis l'appliquer : 

$ terraform init

Initializing provider plugins...

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, it is recommended to add version = "..." constraints to the
corresponding provider blocks in configuration, with the constraint strings
suggested below.

* provider.cloudstack: version = "~> 0.1"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.


Avant de lancer notre déploiement (ici en zone basic), nous pouvons vérifier ce qui sera exécuté sans rien appliquer via la commande :

  1. terraform plan
$ terraform plan
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.


------------------------------------------------------------------------

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  + cloudstack_instance.TerraformVM1
      id:                            <computed>
      display_name:                  <computed>
      expunge:                       "true"
      group:                         <computed>
      ip_address:                    <computed>
      keypair:                       "MY_SSH_KEYPAIR"
      name:                          "TerraformVM1"
      network_id:                    <computed>
      project:                       <computed>
      root_disk_size:                <computed>
      security_group_ids.#:          "1"
      security_group_ids.3260590242: "84be7eef7-4pne-51c6-9abf6f3f9-c4zoek90887"
      service_offering:              "t1.pico"
      tags.%:                        <computed>
      template:                      "Debian 9 - Minimal - 64bits"
      zone:                          "US-FL-MIAMI02-Z2-BASIC"


Plan: 1 to add, 0 to change, 0 to destroy.

------------------------------------------------------------------------

Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.

Si c'est bien ce que nous voulons faire alors nous pouvons appliquer via la commande "terraform apply" et saisir "yes" pour confirmer quand cela nous est demandé : 

$ terraform apply

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:

Terraform will perform the following actions:

Ici nous venons de déployer en quelques secondes, une instance nommée "TerraformVM1" avec le modèle "Debian 9 - Minimal - 64bits" dans la zone basic "US-FL-MIAMI02-Z2-BASIC" avec l'offre de calcul "t1.pico".

Nous pouvons voir celle-ci depuis notre interface Cloud Ikoula One :

Nous pouvons nous connecter sur notre instance fraichement déployée. Note : Pour que cela fonctionne il faut que le 安全组 dans lequel nous avons déployé le permette, sinon il faudra y rajouter une règle autorisant la connexion. 

$ ssh -i MY_SSH_KEYPAIR root@38.93.X.X

Pour supprimer notre instance, il nous suffira d'exécuter la commande "terraform destroy" et valider en saisissant "yes" quand cela nous est demandé : 

$ terraform destroy

Do you really want to destroy?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.

  Enter a value: yes
