使用terraform+ansible交付个nacos集群

最近博主在用python折腾nacos，顺便写下nacos的快速构建方式

terraform创建资源

主要资源：

• 三个nacos节点
• 一个mysql节点
• 一个nginx节点
• 将本地的某用户的公钥配置到上述节点中
• 本地用模板生成ansible主机清单文件
• 创建dns记录到nginx主机

准备项目目录

xadocker@xadocker-virtual-machine:~$ cd workdir/datadir/terraform/
xadocker@xadocker-virtual-machine:~/workdir/datadir/terraform$ mkdir -p tf-nacos-cluster/ansible-deploy
xadocker@xadocker-virtual-machine:~/workdir/datadir/terraform$ cd tf-nacos-cluster/

provider的ak/sk配置

xadocker@xadocker-virtual-machine:~/Desktop/workdir/datadir/terraform/tf-nacos-cluster$ cat providers.tf 
provider "alicloud" {
  access_key = var.access_key
  secret_key = var.secret_key
  region = var.region
}

provider版本配置

注意这里博主将terraform state保存在oss中，需要读者自行提前准备

xadocker@xadocker-virtual-machine:~/Desktop/workdir/datadir/terraform/tf-nacos-cluster$ cat version.tf 
terraform {
  backend "oss" {
    profile = "terraform"
    bucket  = "iac-tf-oss-backend"
    prefix  = "cluster-manager/env-dev/nacos-cluster"
    access_key = "ossak"
    secret_key = "osssk"
    region     = "cn-guangzhou"
  }
  required_providers {
    alicloud = {
      #source = "aliyun/alicloud"
      source = "local-registry/aliyun/alicloud"
      version = "1.166.0"
    }
    local = {
      #source = "hashicorp/local"
      source = "local-registry/hashicorp/local"
      version = "2.2.3"
    }
    archive = {
      #source = "hashicorp/archive"
      source = "local-registry/hashicorp/archive"
      version = "2.2.0"
    }
    http = {
      #source = "hashicorp/http"
      source = "local-registry/hashicorp/http"
      version = "3.2.1"
    }
    null = {
      #source = "hashicorp/null"
      source = "local-registry/hashicorp/null"
      version = "3.2.1"
    }
    random = {
      #source = "hashicorp/random"
      source = "local-registry/hashicorp/random"
      version = "3.4.3"
    }
    template = {
      #source = "hashicorp/template"
      source = "local-registry/hashicorp/template"
      version = "2.2.0"
    }
  }
}

variables配置

xadocker@xadocker-virtual-machine:~/Desktop/workdir/datadir/terraform/tf-nacos-cluster$ cat variables.tf 
variable "access_key" {
  type = string
  default = "xxxxxxx"
  sensitive = true
}
# export TF_VAR_alicloud_access_key=""

variable "secret_key" {
  type = string
  default = "xxxxxxxxxx"
  sensitive = true
}
# export TF_VAR_alicloud_secret_key=""

variable "region" {
  type = string
  default = "cn-guangzhou"
}
# export TF_VAR_region="cn-guangzhou"

main资源声明配置

nginx负载配置模板

• 通过groups['nacos']取得nacos组内对象
• 通过hostvars[i]['ansible_default_ipv4']['address']获取nacos组的内网地址

后续调整

• terraform资源配置调整
  • 创建无公网ip ECS，使得nacos集群限制在内网即可，此处有公网ip是因为博主在外网测试使用
• ansible剧本调整
  • 使用block去除掉大量的when判断，直接点用roles方式配置~

后续也可以将此工程目录托管至gitlab中，配合jenkins进行 giops 管理
