How to convert Jenkins string parameter to Terraform map variable?

问题

我试图将字符串参数传递给 Terraform 的映射变量，但收到错误消息 "Invalid number literal"。在通过 terraform apply -var ... 传递 Jenkins 参数时，如何访问 Terraform 映射中的键和值并不太清楚。

Jenkinsfile:

  1. pipeline {
  2.     agent any
  4.     parameters {
  5.         string(name: 'IP1', defaultValue: '', description: 'Enter first IP address')
  6.     }
  8.     stages {
  9.         stage('Git Checkout') {
  10.             steps {
  11.                 git branch: 'branch1', credentialsId: '', url: 'http://<redacted>.git'
  12.             }
  13.         }
  14.         stage('Deploy Terraform') {
  15.             steps {
  16.                 script {
  17.                     dir('Linux') {
  18.                         sh """
  19.                         terraform init
  20.                         terraform plan
  21.                         terraform apply -var 'vms=${params.IP1}' --auto-approve
  22.                         """
  23.                     }
  24.                 } 
  25.             }
  26.         }
  27.     }
  28. }

variables.tf:

  1. variable "vm_map" {
  2.   type = map(object({
  3.     name = string
  4.     ip   = string
  5.   }))
  6.   default = {
  7.     "first" = {
  8.       name = "ubuntu-jenkins1"
  9.       ip   = "172.30.100.160"
  10.     }
  11.     "second" = {
  12.       name = "ubuntu-jenkins2"
  13.       ip   = "172.30.100.161"
  14.     }
  15.     "third" = {
  16.       name = "ubuntu-jenkins3"
  17.       ip   = "172.30.100.162"
  18.     }
  19.   }
  20. }

I'm trying to pass string parameter(s) to a Terraform map variable, but receiving error "Invalid number literal". It's not quite clear how to access keys and values in Terraform maps when passing a Jenkins parameter via terraform apply -var ...

Jenkinsfile:

  1. pipeline {
  2.     agent any
  4.     parameters {
  5.         string(name: &#39;IP1&#39;, defaultValue: &#39;&#39;, description: &#39;Enter first IP address&#39;)
  6.     }
  7.     
  8.     stages {
  9.         stage(&#39;Git Checkout&#39;) {
  10.             steps {
  11.                 git branch: &#39;branch1&#39;, credentialsId: &#39;&#39;, url: &#39;http://&lt;redacted&gt;.git&#39;
  12.             }
  13.         }
  14.         stage(&#39;Deploy Terraform&#39;) {
  15.             steps {
  16.                 script {

  23.                                 &quot;&quot;&quot;
  24.                             }
  25.                     } 
  26.                 }

我弄清楚了！你可以将'vm1'替换为标识第一个地图对象的任何值。

  1. terraform apply -var vms={'vm1': {name: "ubuntu",ip: "${params.IP1}"}} --auto-approve

如果你还想为虚拟机名称添加一个名字字符串参数，它将如下所示：

  1. terraform apply -var vms={'vm1': {name: "${params.VM_NAME1}",ip: "${params.IP1}"}} --auto-approve

这是用于多个虚拟机的terraform apply命令：

  1. terraform apply -var 'vm_map={"first": {"name": "ubuntu-jenkins1", "ip": "172.30.100.160"}, \
  2.       "second": {"name": "ubuntu-jenkins2", "ip": "172.30.100.161"}, \
  3.       "third": {"name": "ubuntu-jenkins3", "ip": "172.30.100.162"}}' --auto-approve
英文:

I figured it out! You can substitute 'vm1' for any value that identifies the first map object.

  1. terraform apply -var vms=&#39;&#39;&#39;{vm1: {name: &quot;ubuntu&quot;,ip: &quot;${params.IP1}&quot;}}&#39;&#39;&#39; --auto-approve

If you also wanted to add a name string parameter for the vm name, it would look like

  1. terraform apply -var vms=&#39;&#39;&#39;{vm1: {name: &quot;${params.VM_NAME1}&quot;,ip: &quot;${params.IP1}&quot;}}&#39;&#39;&#39; --auto-approve

Here's the terraform apply for multiple vm's

  1. terraform apply -var &#39;vm_map={&quot;first&quot;: {&quot;name&quot;: &quot;ubuntu-jenkins1&quot;, &quot;ip&quot;: &quot;172.30.100.160&quot;}, \
  2.       &quot;second&quot;: {&quot;name&quot;: &quot;ubuntu-jenkins2&quot;, &quot;ip&quot;: &quot;172.30.100.161&quot;}, \
  3.       &quot;third&quot;: {&quot;name&quot;: &quot;ubuntu-jenkins3&quot;, &quot;ip&quot;: &quot;172.30.100.162&quot;}}&#39; --auto-approve
