before start you need gcloud setup and terraform setup as well you can follow my 2020 setup
1- install google provider
First we need to install google provider on terraform if you didnt do it yet !
create a file provider.tf
provider "google" {
credentials = file("./credentials/serviceaccount.json")
project = "demo"
region = "us-east1"
}
now run terraform init, gonna output something like
* provider.google: version = "~> 3.32"
2- create a cluster kubernets
create a file as you wish (all .tf from the folder is gonna be loaded ), I used gkecluster.tf
resource "google_container_cluster" "gke-cluster" {
name = "uelei-gke-cluster"
network = "default"
location = "us-east1-b"
initial_node_count = 1
provisioner "local-exec" {
command = "gcloud container clusters get-credentials ${google_container_cluster.gke-cluster.name} --zone ${google_container_cluster.gke-cluster.zone} --project [PROJECT_ID]"
}
}
ps. local-exec is only for export kubectl credentials, you can do it manualy after terraform apply
now run terraform apply, and answer yes when prompted, all the magic is goona work !
Done !!
extras
You can also set a node pool with your disired machines
resource "google_container_node_pool" "gke-cluster-nodepool" {
name = "gke-cluster-node-pool"
location = google_container_cluster.gke-cluster.location
cluster = google_container_cluster.gke-cluster.name
node_count = 2
node_config {
preemptible = true
machine_type = "e2-micro"
metadata = {
disable-legacy-endpoints = "true"
}
oauth_scopes = [
"https://www.googleapis.com/auth/logging.write",
"https://www.googleapis.com/auth/monitoring",
"https://www.googleapis.com/auth/devstorage.read_only"
]
}
}
also add
remove_default_node_pool = true to your google_container options
thats it !
