How to use the PowerShell plugin
Run PowerShell scripts for Windows automation, Azure management, and cross-platform scripting from Kestra flows.
Common properties
containerImage defaults to mcr.microsoft.com/powershell. taskRunner defaults to Docker and can be overridden for other execution environments.
Tasks
Script runs inline PowerShell code defined in the script property — best for short, flow-specific logic. Commands runs PowerShell commands against script files; use it when your scripts live in namespace files shared across flows, or are cloned from a Git repository with a preceding Clone task.
Install PowerShell modules in beforeCommands with Install-Module -Name <Module> -Force -AllowClobber. For Azure automation, Az module is the standard; for Microsoft Graph, use Microsoft.Graph. Use a custom containerImage pre-built with your modules to avoid long install times on each execution.
