【问题描述】：

我想从 chart.yaml 文件中获取 appVersion 并与从 project.csproj 文件中获取的版本进行比较。

所以，我创建了三个任务

从 project.csproj 获取版本的版本阅读器 文件内容到变量以从chart.yaml获取内容 比较版本和appVersion的powerscript shell

文件内容到变量获取所有内容。我只想获取appversion。

怎么可能像这样$env:helmchart_appVersion 如何从 chart.yaml 获取 appVersion ？

这是我的例子。

$env:Project_Version 正在从版本阅读器获取

$env:helmchart 正在从文件内容获取变量

chart.yaml 文件：

apiVersion: v2
name: asset-api
description: Helm Chart for Kubernetes

# A chart can be either an 'application' or a 'library' chart.
#
# Application charts are a collection of templates that can be packaged into versioned archives
# to be deployed.
#
# Library charts provide useful utilities or functions for the chart developer. They're included as
# a dependency of application charts to inject those utilities and functions into the rendering
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
type: application

# This is the chart version. This version number should be incremented each time you make changes
# to the chart and its templates, including the app version.
# Versions are expected to follow Semantic Versioning (https://semver.org/)
version: 1.5.2

# This is the version number of the application being deployed. This version number should be
# incremented each time you make changes to the application. Versions are not expected to
# follow Semantic Versioning. They should reflect the version the application is using.
# It is recommended to use it with quotes.
appVersion: "1.0.2"

比较脚本：

 write-host($env:helmchart)
 write-host($env:helmchart -match "appVersion: ")
 write-host($env:Project_Version)
if($env:helmchart -match "appVersion: " + $env:Project_Version) 
     write-host('Helm Chart appVersion Validated!')

else 
 write-error 'Helm Chart appVersion not matched with your project version! Check Chart.yaml file!'

【问题讨论】：

什么不适用于您的解决方案？你采取了哪些步骤来调试它？

文件内容到变量获取所有内容。我只想获取 appversion。

【参考方案1】：

我注意到了，缺少的双引号没有给出错误。

$env:Project_Version 是 1.0.2 $env:helmchart 是 appVersion: "1.0.2"

所以脚本应该是：

 if($env:helmchart -match 'appVersion: "' + $env:Project_Version '"') 

     write-host('Helm Chart appVersion Validated!')

else 

   write-error 'Helm Chart appVersion not matched with your project version! Check 
    Chart.yaml file!'
