问题
I have an Azure Pipeline setup with MyVariable variable defined:
How do I write Azure PowerShell Inline Script to read the variable, and set it to a value after some processing?
回答1:
Reading:
Variables are exposed as environment-variables, to read the variable "TestVar" you can do this:
$myScriptVariable = $env:TESTVAR
Note that "." will be replaced with "_" and all is uppercase.
Setting or Updating:
To set or update a variable you'll have to write following 'command' to the host with "write-host":
Write-Host "##vso[task.setvariable variable=testvar;]testvalue"
There are more logging-commands for different actions, i'll just leave the link to the documentation here -> https://github.com/Microsoft/azure-pipelines-tasks/blob/master/docs/authoring/commands.md
回答2:
build variables are exposed as environment variables inside build steps, so you can just reference it using normal powershell syntax:
$env:MyVariable
