如何決議 yaml 檔案以從中提取 appVersion？
我可以將檔案內容與檔案內容一起讀取到變數以獲取所有內容，但我無法決議 yaml 檔案以從中提取 appVersion。
PowerShell 腳本：
# get chart.yaml file content to yamlfilecontent variable.
write-host($env:yamlfilecontent)
# how to parse content ?
write-host($env:yamlfilecontent["appVersion"])
圖表.yaml
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"

不幸的是，從 7.2 版本開始，PowerShell沒有決議 YAML 的內置支持 - 請參閱GitHub 問題 #3607 中的相關功能請求。
但是，可以使用第三方模塊，例如powershell-yaml，可從此處的 PowerShell 庫中獲得，您可以從此處將其直接部署到 Azure 自動化。要在本地安裝它，請使用Install-Module -Name powershell-yaml.
假設模塊已安裝，以下是如何決議問題中的 YAML，使用here-string定義輸入文本：
$yamlText = @'
apiVersion: v2
name: asset-api
description: Helm Chart for Kubernetes
# A chart can be either an 'application' or a 'library' chart.
# ...
version: 1.5.2
# This is the version number of the application being deployed. This version number should be
# ...
appVersion: "1.0.2"
'@
($yamlText | ConvertFrom-Yaml).appVersion
1.0.2如預期的那樣，上述產量為 。
ConvertFrom-Yaml輸出一個表示 YAML 輸入的有序哈希表（技術上，一個 type 的實體[System.Collections.Specialized.OrderedDictionary]），其條目 PowerShell 允許您訪問，就好像它們是屬性（例如.appVersion）或使用索引語法（例如['appVersion']）。
