[英]How to limit disk usage on kubernetes cluster using terraform
我一直在玩 GCP 免費計划。 我正在嘗試學習如何將 gitops 與 IaC 一起應用。 為此,我嘗試使用 terraform 為 kube.netes 集群創建基礎設施,使用谷歌作為雲提供商。
設法配置 Github 操作以在進行推送時應用更改。 但是我收到以下錯誤:
│ Error: googleapi: Error 403: Insufficient regional quota to satisfy request: resource "SSD_TOTAL_GB": request requires '300.0' and is short '50.0'. project has a quota of '250.0' with '250.0' available. View and manage quotas at https://console.cloud.google.com/iam-admin/quotas?usage=USED&project=swift-casing-370717., forbidden

│ with google_container_cluster.primary,
│ on main.tf line 26, in resource "google_container_cluster" "primary":
│ 26: resource "google_container_cluster" "primary" ***
上面提到的terraform配置文件如下:
# https://registry.terraform.io/providers/hashicorp/google/latest/docs
provider "google" {
project = "redacted"
region = "europe-west9"
}
# https://www.terraform.io/language/settings/backends/gcs
terraform {
backend "gcs" {
bucket = "redacted"
prefix = "terraform/state"
}
required_providers {
google = {
source = "hashicorp/google"
version = "~> 4.0"
}
}
}
resource "google_service_account" "default" {
account_id = "service-account-id"
display_name = "We still use master"
}
resource "google_container_cluster" "primary" {
name = "k8s-cluster"
location = "europe-west9"
# We can't create a cluster with no node pool defined, but we want to only use
# separately managed node pools. So we create the smallest possible default
# node pool and immediately delete it.
remove_default_node_pool = true
initial_node_count = 1
}
resource "google_container_node_pool" "primary_preemptible_nodes" {
name = "k8s-node-pool"
location = "europe-west9"
cluster = google_container_cluster.primary.name
node_count = 1
node_config {
preemptible = true
machine_type = "e2-small"
# Google recommends custom service accounts that have cloud-platform scope and permissions granted via IAM Roles.
service_account = google_service_account.default.email
oauth_scopes = [
"https://www.googleapis.com/auth/cloud-platform"
]
}
}
看來我需要限制資源,以便它們最多使用 250 GB,我該怎么做?
根據文檔默認大小為 100GB 並將其更改為 50,如下所示:
resource "google_container_node_pool" "primary_preemptible_nodes" {
name = "k8s-node-pool"
location = "europe-west9"
cluster = google_container_cluster.primary.name
node_count = 1
node_config {
preemptible = true
machine_type = "e2-small"
disk_size_gb = 50
# Google recommends custom service accounts that have cloud-platform scope and permissions granted via IAM Roles.
service_account = google_service_account.default.email
oauth_scopes = [
"https://www.googleapis.com/auth/cloud-platform"
]
}
}
盡管減小了大小,但錯誤消息根本沒有改變。
google_container_cluster
資源還允許您指定磁盤使用情況。 更新配置如下:
resource "google_container_cluster" "primary" {
name = "k8s-cluster"
location = "europe-west9"
# We can't create a cluster with no node pool defined, but we want to only use
# separately managed node pools. So we create the smallest possible default
# node pool and immediately delete it.
remove_default_node_pool = true
initial_node_count = 1
node_config {
disk_size_gb = 50
}
}
