CCE Node Pool Terraform Module

Terraform module which creates node pool resources for HuaweiCloud CCE clusters.

Usage

module "cce_node_pool" {
  source = "./modules/node-pool"

  cluster_id         = "cluster-xxxxx"
  name               = "my-node-pool"
  initial_node_count = 2
  flavor_id          = "s7n.2xlarge.2"
  availability_zone  = "tr-west-1a"
  os                 = "EulerOS 2.9"
  password           = "YourSecurePassword123!"

  root_volume = {
    size       = 40
    volumetype = "SAS"
  }

  data_volumes = [{
    size       = 100
    volumetype = "SAS"
  }]

  scall_enable   = true
  min_node_count = 1
  max_node_count = 10

  labels = {
    "node-pool" = "default"
  }

  tags = {
    Environment = "dev"
  }
}

Features

This module supports the following features:

• ✅ Node Pool Management: Create and manage CCE node pools
• ✅ Auto Scaling: Auto-scaling support at node pool level
• ✅ Storage Configuration: Root and data volume configuration
• ✅ Security: Security group, pod security group, and taint management
• ✅ Kubernetes Integration: Label and taint management
• ✅ Billing: Prepaid and postpaid mode support
• ✅ Multi-AZ: Availability zone support
• ✅ Extended Parameters: Advanced node configuration parameters
• ✅ Storage Groups: Storage selector and group configuration
• ✅ Extension Scale Groups: Extended scaling groups

Node Pool Types

• vm: Virtual machine nodes (default)
• ElasticBMS: Bare metal server nodes

Auto Scaling

Auto-scaling configuration at node pool level:

scall_enable             = true
min_node_count           = 1
max_node_count           = 10
scale_down_cooldown_time = 10
priority                 = 1

Storage Configuration

Root Volume

root_volume = {
  size       = 40
  volumetype = "SAS"  # SAS, SATA, SSD, GPSSD, ESSD
  kms_key_id = "key-xxxxx"  # Optional: KMS encryption
}

Data Volumes

data_volumes = [
  {
    size       = 100
    volumetype = "SAS"
  },
  {
    size       = 200
    volumetype = "SSD"
    kms_key_id = "key-xxxxx"
  }
]
