SharePoint 2013
 

Applies to: SharePoint Server 2013 Enterprise, SharePoint Foundation 2013

Topic Last Modified: 2013-12-18

Installs an instance of an app.

Install-SPApp -Identity <SPApp> -Web <SPWebPipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

Use the Install-SPApp cmdlet to install an instance of an app within a web application.

 

Parameter Required Type Description

Identity

Required

Microsoft.SharePoint.Administration.SPApp

Specifies the app to install. The App object is created by using the Import-SPAppPackage cmdlet.

Site

Required

Microsoft.SharePoint.PowerShell.SPWebPipeBind

Specifies the web, either as an ID or URL, in which the app will be installed.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

NoteNote:
When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.

Confirm

Optional

System.Management.Automation.SwitchParameter

Prompts you for confirmation before executing the command. For more information, type the following command: get-help about_commonparameters

WhatIf

Optional

System.Management.Automation.SwitchParameter

Displays a message that describes the effect of the command instead of executing the command. For more information, type the following command: get-help about_commonparameters

------------EXAMPLE------------

$spapp = Import-SPAppPackage -Path .\feature-upgrade-v1.spapp -Site http://localhost -Source ([microsoft.sharepoint.administration.spappsource]::ObjectModel)
$instance = Install-SPApp -Web http://localhost -Identity $spapp

This example installs an app by first importing the app package, and then installing it.
