Deploy: IIS Web App Deploy


icon Deploy a Website or Web Application.

Use this task to deploy IIS Websites and Virtual Applications using WebDeploy. Supports file transforms and variable substitution, removing additional files at destination, excluding files from App_Data, and taking the app offline.

To use this task, you must first install the IIS Web App Deployment Using WinRM extension from Visual Studio Marketplace.

Basic arguments

Argument Description
Website name The display name of the existing IIS Website or IIS Web Application to deploy to.
Virtual Application The name of existing virtual application. You can use the IIS Web App Manage task to create an IIS Website or an IIS Web Application.
Package or Folder The folder or file path to the web app package to deploy. Build and Release variables and wild cards are supported. Example: $(System.DefautlWorkingDirectory\**\*.zip)

File Transforms and Variable Substitution options

Argument Description
XML transformation Set this option to specify that configuration transforms will run for *.Release.config and *.<EnvironmentName>.config on the *.config file. Configuration transforms will run prior to the XML variable substitution. XML transforms are supported for only Windows platforms.
XML variable substitution Set this option to specify that variables defined in the Build or Release definition will be matched against the key or name entries in the appSettings, applicationSettings, and connectionStrings sections of any configuration file and parameters.xml. Variable substitution runs after Configuration transforms. Note: If same variables are defined in the Release definition and in the Environment, the Environment variables supersede the Release definition variables.
JSON variable substitution Enter a newline-separated list of JSON files to substitute the variable values. Build and Release system definition variables are excluded from substitution. Files names must be relative to the root folder. Variable substitution runs after Configuration transforms.

To substitute JSON variables that are nested or hierarchical, specify them using JSONPath expressions. For example, to replace the value of ConnectionString in the sample below, you must define a variable as Data.DefaultConnection.ConnectionString in the build or release definition (or the release definition's environment):

      "ConnectionString": "Server=(localdb)\SQLEXPRESS;Database=MyDB;Trusted_Connection=True"

Advanced Deployment options

Argument Description
SetParameters File Optional. Location of the SetParameters.xml file to use.
Remove Additional Files at Destination Set this option to delete files in the Website or Web Application that have no matching files in the Web App zip package.
Exclude Files from the App_Data Folder Set this option to prevent files in the App_Data folder from being deployed.
Take App Offline Set this option to take the website or app offline by placing an app_offline.htm file in the root directory before the deployment begins. The file will be removed after the synchronization operation completes successfully.
Additional Arguments Additional Web Deploy arguments that will be applied when deploying the website or app. Examples: -disableLink:AppPoolExtension and -disableLink:ContentExtension

Do I need an agent?

You need at least one agent to run your build or release. Get an agent.

I can't select a default agent queue and I can't queue my build or release. How do I fix this?

See queues.
