# Infrastructure as code with Terraform and GitLab[](#infrastructure-as-code-with-terraform-and-gitlab "Permalink")
## Motivation[](#motivation "Permalink")
GitLab 中的 Terraform 集成功能使您的 GitOps /基础设施即代码(IaC)工作流能够与 GitLab 的身份验证和授权结合在一起. 这些功能着重于降低团队采用 Terraform,在 GitLab 中有效协作以及支持 Terraform 最佳实践的准入门槛.
## GitLab managed Terraform State[](#gitlab-managed-terraform-state "Permalink")
在 GitLab 13.0 中[引入](https://gitlab.com/groups/gitlab-org/-/epics/2673) .
[Terraform 远程后端](https://www.terraform.io/docs/backends/index.html)使您可以将状态文件存储在远程共享存储中. GitLab 使用[Terraform HTTP 后端](https://www.terraform.io/docs/backends/types/http.html)将状态文件安全地存储在本地存储(默认)或[您选择的远程存储中](../../administration/terraform_state.html) .
由 GitLab 管理的 Terraform 状态后端可以轻松安全地存储 Terraform 状态,并使您免于设置其他远程资源(如 Amazon S3 或 Google Cloud Storage). 其功能包括:
* 在传输和静止时都支持状态文件的加密.
* 锁定和解锁状态.
* 远程 Terraform 计划并执行.
要开始使用 GitLab 管理的 Terraform State,有两种不同的选择:
* [Use a local machine](#get-started-using-local-development).
* [Use GitLab CI](#get-started-using-gitlab-ci).
## Permissions for using Terraform[](#permissions-for-using-terraform "Permalink")
在 GitLab 版本 13.1 中,需要[维护者访问权限](../permissions.html)才能使用 GitLab 管理的 Terraform 状态后端. 在 GitLab 版本 13.2 和更高版本中,需要[维护者访问权限](../permissions.html)才能锁定,解锁和写入状态(使用`terraform apply` ),而需要[开发人员访问权限](../permissions.html)来读取状态(使用`terraform plan -lock=false` ).
## Get started using local development[](#get-started-using-local-development "Permalink")
如果您计划仅运行`terraform plan`并从本地计算机上执行`terraform plan` `terraform apply`命令,这是一种入门的简单方法:
1. 在您的 GitLab 实例上创建项目.
2. 导航 **设置>常规,**并记下您的**项目名称**和**项目 ID** .
3. Define the Terraform backend in your Terraform project to be:
```
terraform {
backend "http" {
}
}
```
4. 使用`api`范围创建一个[个人访问令牌](../profile/personal_access_tokens.html) .
5. 在本地计算机上,运行`terraform init` ,传入以下选项,并用相关值替换`<YOUR-PROJECT-NAME>` , `<YOUR-PROJECT-ID>` , `<YOUR-USERNAME>`和`<YOUR-ACCESS-TOKEN>` . 此命令将初始化 Terraform 状态,并将该状态存储在 GitLab 项目中. 这个例子使用`gitlab.com` :
```
terraform init \
-backend-config="address=https://gitlab.com/api/v4/projects/<YOUR-PROJECT-ID>/terraform/state/<YOUR-PROJECT-NAME>" \
-backend-config="lock_address=https://gitlab.com/api/v4/projects/<YOUR-PROJECT-ID>/terraform/state/<YOUR-PROJECT-NAME>/lock" \
-backend-config="unlock_address=https://gitlab.com/api/v4/projects/<YOUR-PROJECT-ID>/terraform/state/<YOUR-PROJECT-NAME>/lock" \
-backend-config="username=<YOUR-USERNAME>" \
-backend-config="password=<YOUR-ACCESS-TOKEN>" \
-backend-config="lock_method=POST" \
-backend-config="unlock_method=DELETE" \
-backend-config="retry_wait_min=5"
```
Next, [configure the backend](#configure-the-backend).
## Get started using GitLab CI[](#get-started-using-gitlab-ci "Permalink")
如果您不想开始本地开发,也可以使用 GitLab CI 来运行`terraform plan`和`terraform apply`命令.
Next, [configure the backend](#configure-the-backend).
## Configure the backend[](#configure-the-backend "Permalink")
执行`terraform init`命令后,必须配置 Terraform 后端和 CI YAML 文件:
1. 在 Terraform 项目中,通过在`.tf`文件(例如`backend.tf` )中添加以下代码块来定义远程后端,以定义[HTTP](https://www.terraform.io/docs/backends/types/http.html)后端:
```
terraform {
backend "http" {
}
}
```
2. 在项目存储库的根目录中,配置`.gitlab-ci.yaml`文件. 本示例使用一个包含`gitlab-terraform`帮助器的预构建图像. 有关受支持的 Terraform 版本,请参见[GitLab Terraform Images 项目](https://gitlab.com/gitlab-org/terraform-images) .
```
image: registry.gitlab.com/gitlab-org/terraform-images/stable:latest
```
3. 在`.gitlab-ci.yaml`文件中,定义一些环境变量以简化开发. 在此示例中, `TF_ROOT`是必须执行 Terraform 命令的目录, `TF_ADDRESS`是该管道在其上运行的 GitLab 实例上的状态的 URL,并且`TF_ADDRESS`的最后路径段是 Terraform 状态的名称. 项目可能具有多个状态,并且该名称是任意的,因此在此示例中,我们将其设置为项目的名称,并确保使用基于缓存的缓存键在管道中的作业之间缓存`.terraform`目录.州名:
```
variables:
TF_ROOT: ${CI_PROJECT_DIR}/environments/cloudflare/production
TF_ADDRESS: ${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/terraform/state/${CI_PROJECT_NAME}
cache:
key: ${CI_PROJECT_NAME}
paths:
- ${TF_ROOT}/.terraform
```
4. 在`before_script` ,更改为`TF_ROOT` :
```
before_script:
- cd ${TF_ROOT}
stages:
- prepare
- validate
- build
- deploy
init:
stage: prepare
script:
- gitlab-terraform init
validate:
stage: validate
script:
- gitlab-terraform validate
plan:
stage: build
script:
- gitlab-terraform plan
- gitlab-terraform plan-json
artifacts:
name: plan
paths:
- ${TF_ROOT}/plan.cache
reports:
terraform: ${TF_ROOT}/plan.json
apply:
stage: deploy
environment:
name: production
script:
- gitlab-terraform apply
dependencies:
- plan
when: manual
only:
- master
```
5. 将项目推送到 GitLab,这将触发 CI 作业管道. 该管道运行`gitlab-terraform init` , `gitlab-terraform validate`和`gitlab-terraform plan`命令.
以上`terraform`命令的输出应在作业日志中可见.
## Example project[](#example-project "Permalink")
请参阅使用 GitLab 和 Terraform 在自定义 VPC 中部署基本 AWS EC2 的[参考项目](https://gitlab.com/nicholasklick/gitlab-terraform-aws) .
## Output Terraform Plan information into a merge request[](#output-terraform-plan-information-into-a-merge-request "Permalink")
使用[GitLab Terraform Report 工件](../../ci/pipelines/job_artifacts.html#artifactsreportsterraform) ,您可以将`terraform plan`运行中的详细信息直接暴露到合并请求小部件中,使您能够查看有关 Terraform 将创建,修改或销毁的资源的统计信息.
让我们探索如何配置 GitLab Terraform Report 工件. 您可以使用包含上述`gitlab-terraform`帮助器的预构建映像,其中`gitlab-terraform plan-json`输出所需的工件,或者您可以按以下方式手动进行配置:
1. 为简单起见,让我们定义一些可重用的变量,以允许我们多次引用这些文件:
```
variables:
PLAN: plan.cache
PLAN_JSON: plan.json
```
2. 安装`jq` ,这是一种[轻巧灵活的命令行 JSON 处理器](https://stedolan.github.io/jq/) .
3. 为特定的`jq`命令创建一个别名,该别名解析出我们要从`terraform plan`输出中提取的信息:
```
before_script:
- apk --no-cache add jq
- alias convert_report="jq -r '([.resource_changes[]?.change.actions?]|flatten)|{\"create\":(map(select(.==\"create\"))|length),\"update\":(map(select(.==\"update\"))|length),\"delete\":(map(select(.==\"delete\"))|length)}'"
```
**注意:**在使用 Bash 的发行版(例如,Ubuntu)中, `alias`语句不会在非交互模式下扩展. 如果您的管道失败并显示错误`convert_report: command not found` ,则可以通过在脚本中添加`shopt`命令来明确激活别名扩展:
```
before_script:
- shopt -s expand_aliases
- alias convert_report="jq -r '([.resource_changes[]?.change.actions?]|flatten)|{\"create\":(map(select(.==\"create\"))|length),\"update\":(map(select(.==\"update\"))|length),\"delete\":(map(select(.==\"delete\"))|length)}'"
```
4. 定义运行`terraform plan`和`terraform show`的`script` . 这些命令通过管道`PLAN_JSON`输出并将相关位转换为存储变量`PLAN_JSON` . 此 JSON 用于创建[GitLab Terraform Report 工件](../../ci/pipelines/job_artifacts.html#artifactsreportsterraform) . Terraform 报告获取 Terraform `tfplan.json`文件. 收集的 Terraform 计划报告作为工件上传到 GitLab,并在合并请求中显示.
```
plan:
stage: build
script:
- terraform plan -out=$PLAN
- terraform show --json $PLAN | convert_report > $PLAN_JSON
artifacts:
reports:
terraform: $PLAN_JSON
```
有关使用预构建图像的完整示例,请参见[Example `.gitlab-ci.yaml`文件](#example-gitlab-ciyaml-file) .
有关显示多个报告的示例,请参见[`.gitlab-ci.yaml`多个报告文件](#multiple-terraform-plan-reports) .
5. 运行管道会在合并请求中显示小部件,如下所示:
[![Merge Request Terraform widget](https://img.kancloud.cn/f1/aa/f1aa23a6efe2f114b0f32d304f42d36d_1600x288.png)](img/terraform_plan_widget_v13_2.png)
6. Clicking the **查看完整日志** button in the widget takes you directly to the plan output present in the pipeline logs:
[![Terraform plan logs](https://img.kancloud.cn/72/9b/729b0e245abb23e6760ab769c7c2689e_1338x282.png)](img/terraform_plan_log_v13_0.png)
### Example `.gitlab-ci.yaml` file[](#example-gitlab-ciyaml-file "Permalink")
```
image: registry.gitlab.com/gitlab-org/terraform-images/stable:latest
variables:
TF_ROOT: ${CI_PROJECT_DIR}/environments/cloudflare/production
TF_ADDRESS: ${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/terraform/state/${CI_PROJECT_NAME}
cache:
key: ${CI_PROJECT_NAME}
paths:
- ${TF_ROOT}/.terraform
before_script:
- cd ${TF_ROOT}
stages:
- prepare
- validate
- build
- deploy
init:
stage: prepare
script:
- gitlab-terraform init
validate:
stage: validate
script:
- gitlab-terraform validate
plan:

apply:
stage: deploy
environment:

```
### Multiple Terraform Plan reports[](#multiple-terraform-plan-reports "Permalink")
从 13.2 开始,您可以在"合并请求"页面上显示多个报告. 报告还将显示`artifact: name:` 有关建议的设置,请参见下面的示例.
```
image:
name: registry.gitlab.com/gitlab-org/gitlab-build-images:terraform
entrypoint:
- '/usr/bin/env'
- 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'
cache:
paths:
- .terraform
stages:
- build
.terraform-plan-generation:
stage: build
variables:
PLAN: plan.tfplan
JSON_PLAN_FILE: tfplan.json
before_script:
- cd ${TERRAFORM_DIRECTORY}
- terraform --version
- terraform init
- apk --no-cache add jq
script:
- terraform validate
- terraform plan -out=${PLAN}
- terraform show --json ${PLAN} | jq -r '([.resource_changes[]?.change.actions?]|flatten)|{"create":(map(select(.=="create"))|length),"update":(map(select(.=="update"))|length),"delete":(map(select(.=="delete"))|length)}' > ${JSON_PLAN_FILE}
artifacts:
reports:
terraform: ${TERRAFORM_DIRECTORY}/${JSON_PLAN_FILE}
review_plan:

variables:
TERRAFORM_DIRECTORY: "review/"
# Review will not include an artifact name
staging_plan:
