I have a regional cluster for redundancy. In this cluster I want to create a node-pool in just 1 zone in this region. Is this configuration possible? reason I trying this is, I want to run service like RabbitMQ in just 1 zone to avoid split, and my application services running on all zones in the region for redundancy.
I am using terraform to create the cluster and node pools, below is my config for creating region cluster and zone node pool
resource "google_container_cluster" "regional_cluster" {
provider = google-beta
project = "my-project"
name = "my-cluster"
location = "us-central1"
node_locations = ["us-central1-a", "us-central1-b", "us-central1-c"]
master_auth {
username = ""
password = ""
client_certificate_config {
issue_client_certificate = false
}
}
}
resource "google_container_node_pool" "one_zone" {
project = google_container_cluster.regional_cluster.project
name = "zone-pool"
location = "us-central1-b"
cluster = google_container_cluster.regional_cluster.name
node_config {
machine_type = var.machine_type
image_type = var.image_type
disk_size_gb = 100
disk_type = "pd-standard"
}
}
This throws an error message
error creating NodePool: googleapi: Error 404: Not found: projects/my-project/zones/us-central1-b/clusters/my-cluster., notFound
Found out that location
in google_container_node_pool
should specify cluster master's region/zone. To actually specify the node-pool location node_locations
should be used. Below is the config that worked
resource "google_container_cluster" "regional_cluster" {
provider = google-beta
project = "my-project"
name = "my-cluster"
location = "us-central1"
node_locations = ["us-central1-a", "us-central1-b", "us-central1-c"]
master_auth {
username = ""
password = ""
client_certificate_config {
issue_client_certificate = false
}
}
}
resource "google_container_node_pool" "one_zone" {
project = google_container_cluster.regional_cluster.project
name = "zone-pool"
location = google_container_cluster.regional_cluster.location
node_locations = ["us-central1-b"]
cluster = google_container_cluster.regional_cluster.name
node_config {
machine_type = var.machine_type
image_type = var.image_type
disk_size_gb = 100
disk_type = "pd-standard"
}
}
