| tf 文件在 Vim 中的语法加亮是安装的hashivim/vim-terraform;插件
| |
|
| |
| Terraform被设计成一个多云基础设施编排工具,不像CloudFormation那样绑定AWS平台,Terraform可以同时编排各种云平台或是其他基础设施的资源。Terraform实现多云编排的方法就是Provider插件机制。

| | |
| 2 在上一步创建的专有网络中创建一个安全组,并添加一个允许任何地址访问的安全组规则。
| |
| 在terraform.tf文件中增加以下内容。
| |
| resource "alicloud_security_group" "default" {
| |
| name = "default"
| |
| vpc_id = alicloud_vpc.vpc.id
| |

| port_range = "1/65535"
| |
| priority = 1
| |
| security_group_id = alicloud_security_group.default.id
| |
| cidr_ip = "0.0.0.0/0"
| |
| }
| |
| 运行terraform apply #开始创建。 有时time out 再来一次就好了
| |
| 运行terraform show查看已创建的安全组和安全组规则。
| |
| 您也可以登录ECS控制台查看安全组和安全组规则。

| |
| | |
| 3.创建ECS实例。
| |
| 在terraform.tf文件中增加以下内容。
| |
| resource "alicloud_instance" "instance" {
| |
| # cn-beijing
| |
| availability_zone = "cn-beijing-b"
| |
| security_groups = alicloud_security_group.default.*.id
| |
| | |
| # series III 能找个最小的么 ecs.s6-c1m1.small
| |
| instance_type = "ecs.s6-c1m1.small"
| |
| #instance_type = "ecs.n2.small"
| |
| system_disk_category = "cloud_efficiency"
| |
| image_id = "ubuntu_18_04_64_20G_alibase_20190624.vhd"
| |
| instance_name = "test_foo"
| |
| vswitch_id = alicloud_vswitch.vsw.id
| |
| internet_max_bandwidth_out =10
| |
| password = "$Eevan2240881"
| |
| }
| |
| | |
| 说明
| |
| 在上述示例中,指定了internet_max_bandwidth_out= 10,因此会自动为实例分配一个公网IP。
| |
| 详细的参数解释请参见
| |
| | |
| image_id 指定ubuntu_16_0402_32,最终会匹配ubuntu_16_0402_32_40G_alibase_20170711.vhd。

| NOTES 将秘钥直接填入到.tf文件中是十分不安全的,在多用户共同管理资源时,不建议把腾讯云API 的秘钥直接写到源代码里,以免一不小心更新到公开的版本中,造成安全风险。
| |
| | |
| 腾讯云提供了另一种更为安全可靠的方式,把秘钥信息放在环境变量中配置
| |
| | |
| // Configure the secret key in the environment path
| |
| $ export TENCENTCLOUD_SECRET_ID="your_fancy_accessid"
| |
| $ export TENCENTCLOUD_SECRET_KEY="your_fancy_accesskey"
| |
| $ export TENCENTCLOUD_REGION="ap-hongkong"
| |

| 关于 Terraform 工作目录中文件命名
| |
| | |
| Terraform 运行时会读取工作目录中所有的 *.tf, *.tfvars 文件,所以我们不必把所有的东西都写在单个文件中去,应按职责分列在不同的文件中,例如:
| |
| | |
| provider.tf -- provider 配置
| |
| terraform.tfvars -- 配置 provider 要用到的变量
| |
| varable.tf -- 通用变量
| |
| resource.tf -- 资源定义
| |
| data.tf -- 包文件定义
| |
| output.tf -- 输出
| |

| 以此篇最简单的入门出发,以后可以深入了解 Lambda, Lambda 触发器,及 API Gateway, EC2 实例怎么用 Terraform 来管理,也知晓了资源的可用属性应该到哪里去查。
| |
| | |
| 一个小提示:在执行像 terraform plan 或 terraform apply 等命令的时候,可以按下 ctrl + c 让控制台输出详细的日志信息。

| 局部变量可以引用variable,resource,data中的一些资源属性,从而拼接改造需要的样式以供一起资源引用,local比variable更灵活,但local不能从外部来赋值。
| |
| 局部值可能有助于避免在配置中多次重复相同的值或表达式,但是如果过度使用局部值,也可能通过隐藏使用的实际值而使以后的维护人员难以读取配置。
| |
| 仅在某些地方使用单个值或结果且将来可能会更改该值的情况下,才应适度使用局部值。易于在中心位置更改值的能力是本地值的主要优势。

| 目前社区主要有两个 provider:

| Telmate/terraform-provider-proxmox: 用户最多,但是只支持管理虚拟机资源。
| |
| danitso/terraform-provider-proxmox: stars 少,但是可以管理 PVE 的大部分资源,包括节点、用户、资源池、TLS证书等等。
| |
| 代码更顺眼,但是作者忙,没时间合并 pr,导致 Bug 更多一些。

| Initializing the backend...
| |
| Do you want to copy existing state to the new backend?
| |
| Pre-existing state was found while migrating the previous "local" backend to the
| |
| newly configured "oss" backend. An existing non-empty state already exists in
| |
| the new backend. The two states have been saved to temporary files that will be
| |
| removed after responding to this query.
| |
|
| |
| Previous (type "local"): /tmp/terraform3485871911/1-local.tfstate
| |
| New (type "oss"): /tmp/terraform3485871911/2-oss.tfstate
| |
|
| |
| Do you want to overwrite the state in the new backend with the previous state?
| |
| Enter "yes" to copy and "no" to start with the existing state in the newly
| |
| configured "oss" backend.
| |
| | |
| oss bucket中就会有个state文件terraform.tfstate,而我们本地的state文件则为空
| |
| 这时只需要有providers.tf、terraform.tf这两个文件就可在别的地方重用state了

| ==区分不同的环境==
| |
| 一、工作目录和配置文件命名
| |
| | |
| 可以为不同的环境创建不同的工作目录,并使用有意义的命名来区分。例如:
| |
| | |
| production目录用于生产环境配置。
| |
| staging目录用于预发布环境配置。
| |
| development目录用于开发环境配置。
| |
| | |
| | |
| 二、变量文件
| |
| | |
| 定义不同的变量文件
| |
| 为每个环境创建独立的变量文件,比如:
| |
| variables.tfvars用于开发环境,其中包含开发环境特定的变量值,如服务器规格较小、数据库存储量较低等。
| |
| staging.tfvars用于预发布环境,变量值可能介于开发和生产环境之间。
| |
| production.tfvars用于生产环境,具有更高的资源配置和更严格的安全设置。
| |
| 使用变量
| |
| 在 Terraform 配置文件中,可以通过 var.<variable_name> 的方式引用变量。例如:
| |
| | |
| | |
| resource "aws_instance" "example" {
| |
| ami = var.ami_id
| |
| instance_type = var.instance_type
| |
| }
| |
| | |
| | |
| 在运行 Terraform 命令时,可以指定特定的变量文件,如 terraform apply -var-file=staging.tfvars。
| |
| | |
| | |
| 三、环境变量
| |
| | |
| 设置环境变量
| |
| 可以通过设置环境变量来区分不同的环境。例如,在不同的环境中设置不同的 TF_VAR_environment 环境变量。
| |
| 使用环境变量
| |
| 在 Terraform 配置文件中,可以通过 var.<variable_name> 的方式引用环境变量设置的变量值。例如,如果环境变量 TF_VAR_environment 设置为 staging,可以在配置文件中使用:
| |
| | |
| | |
| | |
| resource "aws_instance" "example" {
| |
| ami = var.ami_id
| |
| instance_type = var.instance_type
| |
| tags = {
| |
| Environment = var.environment
| |
| }
| |
| }
| |
| | |
| | |
| 四、模块参数传递
| |
| | |
| 创建模块时传递参数
| |
| 可以将环境相关的参数传递给模块。例如,创建一个 networking 模块,在不同环境中调用这个模块时传递不同的参数。
| |
| | |
| | |
| | |
| module "networking" {
| |
| source = "./networking_module"
| |
| environment = var.environment
| |
| }
| |
| | |
| | |
| 在模块内部使用参数
| |
| 在模块内部,可以根据传入的参数进行不同的配置。例如,在 networking_module 中,可以根据 environment 参数来创建不同规模的网络资源。
| |
| | |
| | |
| | |
| | |
| | |
| variable "environment" {}
| |
| | |
| resource "aws_vpc" "example" {
| |
| cidr_block = if var.environment == "production" then "10.0.0.0/16" else "10.1.0.0/16"
| |
| }
| |
| | |
| | |
| 通过以上方法,可以在 Terraform 中有效地区分不同的环境,实现对不同环境的独立管理和配置
