Deploying Web Packages

This topic describes how you can publish web deployment packages to a remote server by using the Internet Information Services (IIS) Web Deployment Tool (Web Deploy) 2.0.

There are two main ways in which you can deploy a web package to a remote server:

You can use the MSDeploy.exe command-line utility directly.

You can run the [project name].deploy.cmd file that the build process generates.

The end result is the same regardless of which approach you use. Essentially, all the .deploy.cmd file does is to run MSDeploy.exe with some predetermined values, so that you don’t have to provide as much information in order to deploy the package. This simplifies the deployment process. On the other hand, using MSDeploy.exe directly gives you a lot more flexibility over exactly how your package is deployed.

Which approach you use will depend on a variety of factors, including how much control you require over the deployment process and whether you’re targeting the Web Deploy Remote Agent service or the Web Deploy Handler. This topic explains how to use each approach and identifies when each approach is appropriate.

The tasks and walkthroughs in this topic assume that:

You’ve built and packaged your web application, as described in Building and Packaging Web Application Projects.

You’ve modified the SetParameters.xml file to provide the right parameter values for your target environment, as described in Configuring Parameters for Web Package Deployment.

Running the [project name].deploy.cmd file is the simplest way to deploy a web package. In particular, using the .deploy.cmd file offers these advantages over using MSDeploy.exe directly:

You don’t need to specify the location of the web deployment package—the .deploy.cmd file already knows where it is.
You don’t need to specify the location of the SetParameters.xml file—the .deploy.cmd file already knows where it is.
You don’t need to specify source and destination MSDeploy providers—the .deploy.cmd file already knows which values to use.
You don’t need to specify MSDeploy operation settings—the .deploy.cmd file adds the commonly required values to the MSDeploy.exe command automatically.

Before you use the .deploy.cmd file to deploy a web package, you should ensure that:

The .deploy.cmd file, the [project name].SetParameters.xml file, and the web package ([project name].zip) are in the same folder.
Web Deploy (MSDeploy.exe) is installed on the computer that runs the .deploy.cmd file.

The .deploy.cmd file supports various command-line options. When you run the file from a command prompt, this is the basic syntax:

[!code-consoleMain]

   1:  [project name].deploy.cmd [/T | /Y]

   2:                            [/M:<computer name>]

   3:                            [/A:<Basic | NTLM>]

   4:                            [/U:<user name>]

   5:                            [/P:<password>]

   6:                            [/L]

   7:                            [/G:<true | false>]

   8:                            [Additional MSDeploy.exe flags]

You must specify either a /T flag or a /Y flag, to indicate whether you want to perform a trial run or a live deployment respectively (don’t use both flags in the same command). This table explains the purpose of each of these flags.

Flag	Description
/T	Calls MSDeploy.exe with the –whatif flag, which indicates a trial run. Rather than deploying the package, it creates a report of what would happen if you did deploy the package.
/Y	Calls MSDeploy.exe without the –whatif flag. This deploys the package to the local computer or the specified destination server.
/M	Specifies the destination server name or service URL. For more information on the values you can provide here, see the Endpoint Considerations section in this topic. If you omit the /M flag, the package will be deployed to the local computer.
/A	Specifies the authentication type that MSDeploy.exe should use to perform the deployment. Possible values are NTLM and Basic. If you omit the /A flag, the authentication type defaults to NTLM for deployment to the Web Deploy Remote Agent service and to Basic for deployment to the Web Deploy Handler.
/U	Specifies the user name. This applies only if you’re using basic authentication.
/P	Specifies the password. This applies only if you’re using basic authentication.
/L	Indicates that the package should be deployed to the local IIS Express instance.
/G	Specifies that the package is deployed using the tempAgent provider setting. If you omit the /G flag, the value defaults to false.

[!NOTE] Every time the build process creates a web package, it also creates a file named [project name].deploy-readme.txt that explains these deployment options.

In addition to these flags, you can specify Web Deploy operation settings as additional .deploy.cmd parameters. Any additional settings you specify are simply passed through to the underlying MSDeploy.exe command. For more information on these settings, see Web Deploy Operation Settings.

Suppose you want to deploy the ContactManager.Mvc web application project to a test environment by running the .deploy.cmd file. Your test environment is configured to use the Web Deploy Remote Agent service, as described in Configure a Web Server for Web Deploy Publishing (Remote Agent). To deploy the web application, you need to complete the next steps.

To deploy a web application using the .deploy.cmd file

Build and package the web application project, as described in Building and Packaging Web Application Projects.
Modify the ContactManager.Mvc.SetParameters.xml file to contain the correct parameter values for your test environment, as described in Configuring Parameters for Web Package Deployment.
Open a Command Prompt window and navigate to the location of the ContactManager.Mvc.deploy.cmd file.

Type this command, and then press Enter:

[!code-consoleMain]

   1:  ContactManager.Mvc.deploy.cmd /Y /M:TESTWEB1 /A:NTLM

In this example:

The /Y flag indicates that you want to actually deploy the package, rather than doing a trial run.
The /M flag indicates that you want to deploy the package to the server named TESTWEB1. From this value, MSDeploy.exe will attempt to deploy the package to the Web Deploy Remote Agent service at http://TESTWEB1/MSDeployAgentService.
The /A flag indicates that you want to use NTLM authentication. As such, you don’t need to specify a user name and password.

To illustrate how using the .deploy.cmd file simplifies the deployment process, take a look at the MSDeploy.exe command that gets generated and executed when you run ContactManager.Mvc.deploy.cmd using the options shown above.

[!code-consoleMain]

   1:  msdeploy.exe

   2:  -source:package='C:\Users\matt.FABRIKAM\Desktop\ContactManager-03\ContactManager\

   3:   Publish\Out\_PublishedWebsites\ContactManager.Mvc_Package\ContactManager.Mvc.zip' -dest:auto,computerName='TESTWEB1.fabrikam.net', authtype='NTLM',

   4:   includeAcls='False'

   5:  -verb:sync

   6:  -disableLink:AppPoolExtension

   7:  -disableLink:ContentExtension

   8:  -disableLink:CertificateExtension

   9:  -setParamFile:"C:\Users\matt.FABRIKAM\Desktop\ContactManager-03\ContactManager\

  10:   Publish\Out\_PublishedWebsites\ContactManager.Mvc_Package\

  11:   ContactManager.Mvc.SetParameters.xml"

For more information on using the .deploy.cmd file to deploy a web package, see How to: Install a Deployment Package Using the deploy.cmd File.

Using MSDeploy.exe

Although using the .deploy.cmd file generally simplifies the deployment process, there are some situations when it’s preferable to use MSDeploy.exe directly. For example:

If you want to deploy to the Web Deploy Handler as a non-administrator user, you can’t use the .deploy.cmd file. This is due to a bug in Web Deploy 2.0, as described under Endpoint Considerations.
If you want to manually switch between different SetParameters.xml files in different locations, you may prefer to use MSDeploy.exe directly.
If you want to override several MSDeploy.exe command-line arguments, you may prefer to use MSDeploy.exe directly.

When you use MSDeploy.exe, you need to provide three key pieces of information:

A –source parameter that indicates where your data is coming from.
A –dest parameter that indicates where your data is going to.
A –verb parameter that indicates the operation you want to perform.

MSDeploy.exe relies on Web Deploy providers to process source and destination data. Web Deploy includes a lot of providers that represent the range of applications and data sources it can work with—for example, there are providers for SQL Server databases, IIS web servers, certificates, global assembly cache (GAC) assemblies, various different configuration files, and lots of other types of data. Both the –source parameter and the –dest parameter must specify a provider, in the form –source:[providerName]=[location]. When you’re deploying a web package to an IIS website, you should use these values:

The –source provider is always package. For example:
[!code-consoleMain]
```
   1:  -source:package='[path to web package]'
```
The –dest provider is always auto. For example:
[!code-consoleMain]
```
   1:  -dest:auto='[server name or service URL]'
```
The –verb is always sync.

[!code-consoleMain]
```
   1:  -verb:sync
```

In addition, you’ll need to specify various other provider-specific settings and general operation settings. For example, suppose you want to deploy the ContactManager.Mvc web application to a staging environment. The deployment will target the Web Deploy Handler and must use basic authentication. To deploy the web application, you need to complete the next steps.

To deploy a web application using MSDeploy.exe

Build and package the web application project, as described in Building and Packaging Web Application Projects.
Modify the ContactManager.Mvc.SetParameters.xml file to contain the correct parameter values for your staging environment, as described in Configuring Parameters for Web Package Deployment.
Open a Command Prompt window and browse to the location of MSDeploy.exe. This is typically at %PROGRAMFILES%Web Deploy V2.exe.

Type this command, and then press Enter (disregard the line breaks):

[!code-consoleMain]

   1:  MSDeploy.exe

   2:    -source:package="[path]\ContactManager.Mvc.zip"

   3:    -dest:auto,

   4:          computerName="https://stageweb1:8172/MSDeploy.axd?site=DemoSite",

   5:          username="FABRIKAM\stagingdeployer",

   6:          password="Pa$$w0rd",

   7:          authtype="Basic",

   8:          includeAcls="False"

   9:    -verb:sync

  10:    -disableLink:AppPoolExtension

  11:    -disableLink:ContentExtension

  12:    -disableLink:CertificateExtension

  13:    -setParamFile:"[path]\ContactManager.Mvc.SetParameters.xml"

  14:    -allowUntrusted

In this example:

The –source parameter specifies the package provider and indicates the location of the web package.
The –dest parameter specifies the auto provider. The computerName setting provides the service URL of the Web Deploy Handler on the destination server. The authtype setting indicates that you want to use basic authentication, and as such you need to provide a username and a password. Finally, the includeAcls=“False” setting indicates that you don’t want to copy the access control lists (ACLs) of the files in your source web application to the destination server.
The –verb:sync argument indicates that you want to replicate the source content on the destination server.
The –disableLink arguments indicate that you don’t want to replicate application pools, virtual directory configuration, or Secure Sockets Layer (SSL) certificates on the destination server. For more information, see Web Deploy Link Extensions.
The –setParamFile parameter provides the location of the SetParameters.xml file.
The –allowUntrusted switch indicates that Web Deploy should accept SSL certificates that were not issued by a trusted certification authority. If you’re deploying to the Web Deploy Handler, and you’ve used a self-signed certificate to secure the service URL, you need to include this switch.

Automating Web Package Deployment

In a lot of enterprise scenarios, you’ll want to deploy your web packages as part of a larger single-step or automated deployment. Regardless of whether you choose to deploy your web packages by running the .deploy.cmd file or by using MSDeploy.exe directly, you can parameterize your commands and call them from a target in a Microsoft Build Engine (MSBuild) project file.

In the Contact Manager sample solution, take a look at the PublishWebPackages target in the Publish.proj file. This target runs once for each .deploy.cmd file identified by an item list named PublishPackages. The target uses properties and item metadata to build up a full set of argument values for each .deploy.cmd file and then uses the Exec task to run the command.

[!code-xmlMain]

   1:  <Target Name="PublishWebPackages" Outputs="%(PublishPackages.Identity)">

   2:    ...

   3:    <PropertyGroup>

   4:      <_WhatIfSwitch>/Y</_WhatIfSwitch>

   5:      <_WhatIfSwitch Condition=" '$(_WhatIf)'=='true' ">/T</_WhatIfSwitch>

   6:      <_Cmd>

   7:        %(PublishPackages.FullPath) $(_WhatifSwitch) /M:$(MSDeployComputerName)

   8:        /U:$(MSDeployUsername) /P:$(Password) /A:$(MSDeployAuth)

   9:        %(PublishPackages.AdditionalMSDeployParameters)

  10:      </_Cmd>

  11:    </PropertyGroup>

  12:    <Exec Command="$(_Cmd)"/>

  13:  </Target>

Endpoint Considerations

Regardless of whether you deploy your web package by running the .deploy.cmd file or by using MSDeploy.exe directly, you need to specify a computer name or a service endpoint for your deployment.

If the destination web server is configured for deployment using the Web Deploy Remote Agent service, you specify the target service URL as your destination.

[!code-consoleMain]

   1:  http://[server name]/MSDeployAgentService

Alternatively, you can specify the server name alone as your destination, and Web Deploy will infer the remote agent service URL.

[!code-consoleMain]

   1:  [server name]

If the destination web server is configured for deployment using the Web Deploy Handler, you need to specify the endpoint address of the IIS Web Management Service (WMSvc) as your destination. By default, this takes the form:

[!code-consoleMain]

   1:  https://[server name]:8172/MSDeploy.axd

You can target any of these endpoints using either the .deploy.cmd file or MSDeploy.exe directly. However, if you want to deploy to the Web Deploy Handler as a non-administrator user, as described in Configure a Web Server for Web Deploy Publishing (Web Deploy Handler), you need to add a query string to the service endpoint address.

[!code-consoleMain]

   1:  https://[server name]:8172/MSDeploy.axd?site=[IIS website name]

This is because the non-administrator user doesn’t have server-level access to IIS; he or she only has access to a specific IIS website. At the time of writing, due to a bug in the Web Publishing Pipeline (WPP), you can’t run the .deploy.cmd file using an endpoint address that includes a query string. In this scenario, you need to deploy your web package by using MSDeploy.exe directly.

[!NOTE] For more information on the Web Deploy Remote Agent service and the Web Deploy Handler, see Choosing the Right Approach to Web Deployment. For guidance on how to configure your environment-specific project files to deploy to these endpoints, see Configure Deployment Properties for a Target Environment.

Authentication Considerations

Regardless of whether you deploy your web package by running the .deploy.cmd file or by using MSDeploy.exe directly, you need to specify an authentication type. Web Deploy accepts two possible values: NTLM or Basic. If you specify basic authentication, you also need to provide a user name and password. There are various factors you need to be aware of when you select an authentication type:

If you’re deploying to the Web Deploy Remote Agent service, you must use NTLM authentication. The remote agent service doesn’t accept basic authentication credentials.
If you’re deploying to the Web Deploy Handler, you can use either NTLM or basic authentication. The default setting is basic authentication. Although basic authentication relies on user names and passwords being transmitted in plain text, your credentials are protected as the Web Deploy Handler always uses SSL encryption.
If your web package includes a database, and the web server and database server are separate machines, you won’t be able to deploy the database using NTLM authentication due to the NTLM “double-hop” limitation. You need to either use SQL Server credentials in your deployment connection string or supply basic authentication credentials to Web Deploy. This issue is described in more detail in Deploying Membership Databases to Enterprise Environments.
