Terraform 帮我们创建好instance以后，这个时候我们只是有一个空的instance，任何事情都干不了，我们需要做一些初始化的操作，例如安装必要的软件包，增加特定用户，修改特定配置文件等 Terraform 也帮我们提供了这个工具：Provisioner 直接看例子 [crayon-5e595f0af12f7045170608……
Terraform resource之间的依赖问题
Terraform 修改 清理

和上一篇文章不同的地方是我们修改了ami 链接 这个时候如何应用我们的修改呢？我们只需要执行如下命令： [crayon-5e59……

Terraform 如何创建一个aws instance
首先，我们要先安装Terraform， Terraform的安装很简单,以Mac 为例：

$brew install terraform $terraform --help Usage: terraform [-version] [-help] <command> [args] The available commands for execution are listed below. The most common, useful commands are shown first, followed by less common or more advanced commands. If you're just getting started with Terraform, stick with the common commands. For the other commands, please read the help and docs before usage. Common commands: apply Builds or changes infrastructure console Interactive console for Terraform interpolations destroy Destroy Terraform-managed infrastructure env Workspace management fmt Rewrites config files to canonical format get Download and install modules for the configuration graph Create a visual graph of Terraform resources import Import existing infrastructure into Terraform init Initialize a Terraform working directory output Read an output from a state file plan Generate and show an execution plan providers Prints a tree of the providers used in the configuration refresh Update local state file against real resources show Inspect Terraform state or plan taint Manually mark a resource for recreation untaint Manually unmark a resource as tainted validate Validates the Terraform files version Prints the Terraform version workspace Workspace management All other commands: 0.12upgrade Rewrites pre-0.12 module source code for v0.12 debug Debug output management (experimental) force-unlock Manually unlock the terraform state push Obsolete command for Terraform Enterprise legacy (v1) state Advanced state management |
安装完成后我们来使用Terraform在aws中创建一个instance 先看代码 example.tf：

provider "aws" { profile = "default" region = "us-east-1" } resource "aws_instance" "example" { ami = "ami-2757f631" instance_type = "t2.micro" } |
