rerun this command to reinitialize your working directory. If you forget, other

commands will detect it and remind you to do so if necessary.

Add a virtual machine:

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.

Resource actions are indicated with the following symbols:

+ create

Terraform will perform the following actions:

# google_compute_instance.cluster will be created

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

Do you want to perform these actions?

Terraform will perform the actions described above.

Only 'yes' will be accepted to approve.

Enter a value: yes

google_compute_instance.cluster: Creating …

google_compute_instance.cluster: Still creating … [10s elapsed]

google_compute_instance.cluster: Creation complete after 11s [id = cluster]

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

Add a public static IP address and SSH key to the node:

essh @ kubernetes-master: ~ / node-cluster $ ssh-keygen -f node-cluster

Generating public / private rsa key pair.

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in node-cluster.

Your public key has been saved in node-cluster.pub.

The key fingerprint is:
