Расширяемость с помощью external resource, в качестве которого может быть скрипт на BASH:

Создание кластера машин с помощью Terraform
Создание кластера с помощью Terraform рассматривается в Создание инфраструктуры в GCP. Сейчас уделим больше внимания самому кластеру, а не инструментам по его созданию. Создам через панель администратора GCE проект (отображается в шапке интерфейса) node-cluster. Ключ для Kubernetes я скачал IAM и администрирование –> Сервисные аккаунты –> Создать сервисный аккаунт и при создании выбрал роль Владелец и положил в проект под названием kubernetes_key.JSON:
eSSH@Kubernetes-master:~/node-cluster$ cp ~/Downloads/node-cluster-243923-bbec410e0a83.JSON ./kubernetes_key.JSON
Скачал terraform:
essh@kubernetes-master:~/node-cluster$ wget https://releases.hashicorp.com/terraform/0.12.2/terraform_0.12.2_linux_amd64.zip >/dev/null 2>/dev/null
essh@kubernetes-master:~/node-cluster$ unzip terraform_0.12.2_linux_amd64.zip && rm -f terraform_0.12.2_linux_amd64.zip
Archive: terraform_0.12.2_linux_amd64.zip
inflating: terraform
essh@kubernetes-master:~/node-cluster$ ./terraform version
Terraform v0.12.2
Добавили провайдера GCE и запустил скачивание "драйверов" к нему:
essh@kubernetes-master:~/node-cluster$ cat main.tf
provider "google" {
credentials = "${file("kubernetes_key.json")}"
project = "node-cluster"
region = "us-central1"
}essh@kubernetes-master:~/node-cluster$ ./terraform init
Initializing the backend…
Initializing provider plugins…
– Checking for available provider plugins…
– Downloading plugin for provider "google" (terraform-providers/google) 2.8.0…
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.google: version = "~> 2.8"
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.
Добавлю виртуальную машину:
essh@kubernetes-master:~/node-cluster$ cat main.tf
provider "google" {
credentials = "${file("kubernetes_key.json")}"
project = "node-cluster-243923"
region = "europe-north1"
}
resource "google_compute_instance" "cluster" {
name = "cluster"
zone = "europe-north1-a"
machine_type = "f1-micro"
boot_disk {
initialize_params {
image = "debian-cloud/debian-9"
}
}
network_interface {
network = "default"
access_config {}
}
essh@kubernetes-master:~/node-cluster$ sudo ./terraform apply
An execution plan has been generated and is shown below.
