Release your app to environments without deployment agents

  • 项目

| TFS 2015 | Previous version

Important

Release Management features have been integrated into Azure Pipelines and Team Foundation Server (TFS). For more information, see Build and Release in Azure Pipelines.

The newer web-based version is the recommended alternative to the server and client version described in this topic. If you do not already have Release Management installed, we encourage you to use the web-based version in TFS 2015 Update 2 and above or Azure Pipelines instead of the version described here. If you are already using an earlier server and client version, you should be aware that no new features will be added to these versions.

If you want to use Windows PowerShell, Windows PowerShell Desired State Configuration (DSC), or Chef to deploy your app, follow these steps. If you are using deployment agents, go here for instructions.

Why deploy my app this way?

  • If you already deploy your app with PowerShell or DSC, use the same scripts with Release Management.
  • You don't have to install a deployment agent on any machine that you use for the environment.
  • Create complex scripts to deploy using all the features of PowerShell or DSC.
  • If you want to deploy your app to a server machine that is not running a Windows operating system, you can use Chef to do that. (In this version, Chef is supported if you manage your release with an on-premises Release Management server, but it is not supported if you manage your release with Visual Studio Azure Pipelines.)

Set up your environment

Environments without deployment agents are called vNext environments. You can only use these vNext environments with vNext Components, vNext Release Templates and vNext Release Paths to deploy without deployment agents.

To use Windows PowerShell or DSC, you can set up a vNext on-premises environment with physical or virtual machines (VMs), or a vNext Azure environment with Azure VMs. For Chef, you must set up a vNext on-premises environment.

You need Release Management for Visual Studio 2015 to deploy without deployment agents. See Install Release Management.

If you haven't already done so, connect to release management and add stages for your release.

Prerequisites for computers

Based on the tool that you are using to deploy, check these prerequisites for any computer you plan on using in your environment.

DSC

  • Windows 8.1, Windows Server 2012 R2: DSC is already installed.

Chef

  • Target node must be bootstrapped and registered with your Chef server.
  • Add an attribute to the cookbook that maps to build drop location.
  • Upload cookbooks to the Chef server.
  • Assign recipes to the target node.
  • Set up your Release Management Server as a Chef Workstation. Instructions are here.
  • Release Management uses Knife to communicate with Chef. Run the following commands to install the Windows plugin for Knife:
    • gem install knife-windows --no-ri --no-rdoc
    • gem install knife-reporting --no-ri --no-rdoc

Set up Microsoft Azure environments

Microsoft Azure makes it easy to set up VMs to use as servers in your environment. Azure adds your VMs to cloud services. You'll need a Microsoft Azure account to create your VMs. If you don't have one yet, sign up for free through Visual Studio Dev Essentials.

In Release Management, you'll create an Azure environment for each release stage. You then link your environment to a cloud service associated with your Azure subscription. Release Management can then access any of the VMs in this cloud service to use in the environment. If you have multiple VMs associated with a cloud service, you can add any of these VMs as servers to your Azure environment in Release Management.

  1. In the Azure portal, create the VMs that you want to use in your release environment. By default, each VM you create is added to its own cloud service. If you want to use multiple VMs in an environment, they must all be in the same cloud service. To add a VM to a specific cloud service, choose From Gallery when you create the VM.

    Windows Azure portal, Virtual Machines tab

  2. For each Azure VM that runs Windows, if the prerequisites listed above for PowerShell and DSC are not yet met, add the Visual Studio Release Management extension to meet the prerequisites. Learn how.

  3. Add the details for your Azure subscription to Release Management.

    Administration tab; Manage Azure tab; click New

    Download the settings file from the Azure portal and open it with a text editor, such as Notepad, to get your subscription ID and Management Certificate key. (After using the settings file, consider deleting or securing it as it contains information that can be used by others to access your Azure account.) Go here to get the name of an existing storage account or add a new storage account using the Azure portal.

    Enter the details of your Azure subscription and a storage account that you want to use

  4. Create a vNext Azure environment for each stage in your release path.

    Configure Paths tab; Environments tab; click New and then choose New vNext: Azure from the dropdown list

  5. Link your Azure environment in Release Management to the Azure subscription that you entered.

    Configure Paths tab; Environments tab; click Link Azure Environment

    Select the Azure subscription that you want to use with this environment. (Sometimes it takes a few minutes to load your subscription.) The Azure cloud services for this subscription are displayed. Select a cloud service to link the subscription to the environment.

    Select subscription from dropdown list; choose the VM; click Link

    If there are no cloud services for your Azure subscription, you cannot link it to the environment. Go to the Azure portal and create a VM for this subscription. When you create a VM, a cloud service with the same name is created by default. Refresh to select this cloud service.

  6. Link your Azure VMs in the cloud service as servers for the environment.

    From the Environments tab, click Link Azure Servers

    Select the servers that you want to link.

  7. For each server, you can add configuration variables that can be used by your deployment actions. For example, you can add username and password here.

    If you add configuration variables with the same name for actions in your release template, the values in any actions will override the values that you set here.

  8. View the environments that you created in the Environments tab. The type is shown as Azure.

Set up on-premises (standard) environments

Servers in your on-premises environment must have a fully qualified domain name. They can be virtual or physical machines. All these machines must be in the same domain, or in two-way trusted domains. Use on-premises environments if you want to deploy using Chef.

  1. For PowerShell or DSC deployment, enable PowerShell remoting and set up the WinRM port for HTTP communication. Run these commands from a PowerShell session with administrator privileges on all the server machines in your environment:

    • Enable-PSRemoting -Force
    • winrm quickconfig -transport:http

    More details about how to configure Windows Remote Management can be found here, including how to set up session time-outs for a machine. For Chef, check that each server is set up as required in the prerequisites section above.

  2. Create a vNext on-premises environment for each stage.

    Configure Paths tab; Environments tab; click New and select New vNext: Standard

  3. Open an on-premises environment to add your servers for the environment. You need to supply the DNS name and the WinRM port number. If you don't know the port number, run this command:

    winrm e winrm/config/listener

    To deploy with Chef, add your Chef node as a server. This machine can run any OS supported by Chef and can be a virtual or physical machine. The server name and port must match the node name and port that's registered with the Chef server. For Unix-based machines, use ssh port to find the port.

    Configure Paths tab; Environments tab; from the Servers section, click Add

  4. For each server, you can add configuration variables that can be used by your deployment actions. For example, you can add username and password here. If you add configuration variables with the same name for actions in your release template, the values in any actions will override the values that you set here.

  5. View the environments that you created in the Environments tab. The type is shown as Standard.

Create a release template

Check that the code for your app has been added to version control. You also need a build definition that builds your app.

  1. Create a vNext release path to represent the stages that your release must go through.

    Configure Paths tab; vNext Release Paths tab; click New

    Choose the environment and approvers to use for each stage of your release. You can add multiple final approvers for each stage if you want to.

    vNext Release Paths tab; click Add in Stages section

  2. Create a vNext component for each component of your app that you need to deploy separately. For example, you might have a component to deploy your web server and another component to deploy your database. Choose the location of the build package for each component to use when your app is deployed.

    Configure Apps tab; Components tab; click New to add a component

    For Chef deployments, use the Build externally option and supply the path to the package. This can be a URL or an FTP path. This path will be used as the node's attribute value by the cookbooks to access the package for your app.

  3. Create a vNext release template and use the release path that you just added.

    Configure Apps tab; vNext Release Templates tab; click New

    Add all the vNext components that you created to this vNext release template. (Right-click Components in the toolbox to show the context menu.)

    Configure Apps tab; vNext Release Templates tab; right-click Components in the Toolbox and click Add in the context menu

    Select the components and add them to your release template.

    Components dialog box; select component; click Link to add the component to the vNext Release Template

    You can now see the components in the toolbox and you can use these as parameters for your deployment actions.

  4. Add the deployment actions from the toolbox based on your environment type and how you want to deploy your app. You need to do this for each stage in this vNext release path.

    Drag the deployment action from the toolbox to the deployment sequence

    For on-premises environments: Open the Standard section in the toolbox.

    • To deploy with Powershell or DSC, drag the Deploy to Standard Environment action into the deployment sequence. Parameter details for this action are here.
    • To deploy with Chef, drag the Deploy Using Chef action into the deployment sequence. Parameter details for this action are here.

    For Windows Azure environments: Open the Azure section in the toolbox. Drag the Deploy to Azure Environment, the Start Environment, or the Stop Environment actions into the deployment sequence. Parameter details for the Deploy to Azure Environment action are here.

    Add your PowerShell or DSC script name and relative path to the action. A DSC script must contain a DSC configuration and a command to create a .mof file for that DSC configuration. You should not call Start -DscConfiguration here. Release Management will do this for you. You can use $applicationPath in your script - this is the relative path you added as your component package path.

    This example shows how to use a DSC configuration script to copy files with a command to generate a .mof file at the end.

    configuration FileCopy
{
  Node $AllNodes.NodeName  
  {
    File CopyDeploymentBits
    {  
      Ensure = "Present"
      Type = "Directory"
      Recurse = $true
      SourcePath = $applicationPath
      DestinationPath = $Node.DeploymentPath
    }
  }
}

FileCopy -ConfigurationData $ConfigData --"Verbose

    The parameter values $AllNodes and $Node in this example are from an optional configuration file - not to be confused with the DSC configuration. Use configuration files if you want to use the same script but parameterize the values when you deploy to a different stage. Here's what this configuration file looks like.

    $ConfigData = @{
AllNodes = @(
    @{ NodeName = $env:COMPUTERNAME;
        DeploymentPath = $env:SystemDrive + "\FolderCopyTest"
     }
  )
}

  1. Start a new release.
  2. Approve steps in a stage.

FAQ

Q: Are there any DSC actions that are not currently supported by Release Management?

A: Yes. Set-DscLocalConfigurationManager is not supported.

Q: What other differences are there between using a vNext release template and the deployment agent-based release template?

A: Apart from not needing deployment agents, these are the other differences:

  • You cannot drag components and servers into the deployment sequence editor. These are parameters to deployment actions only.
  • The vNext components are not associated with tools.
  • You cannot use custom tools, or custom actions for your deployment.
  • Flow control is not supported, so if an action fails all previous actions will be rolled back. It is recommended to handle this in your scripts.

Q: What are each of the parameters for the Deploy to Standard Environment action?

A: Here are the details:

  • ServerName: On-premises machine where you want to deploy this component.

  • UserName: Account name to connect to the server. This user must be a domain user and also a member of the Administrators group on the server.

  • Password: Password for the user account.

  • PSScriptPath: Path and filename of PowerShell or DSC script to deploy this component. This path is relative to the package path for the component.

  • PSConfigurationPath: Path and filename of PowerShell or DSC script to configure the server before deployment of this component. This script is optional. It will be run before the script in the PSScriptPath parameter. This path is relative to the package path for the component.

  • UseCredSSP: If set to true, the scripts use the same PowerShell session as Release Management when it connects remotely to the server. You must manually enable CredSSP. Run the following PowerShell command on the server with administrator privileges.

    Enable-WSManCredSSP -Role Client -DelegateComputer <Server DNS Name> -Force

    By default, this value is false.

  • UseHTTPS: Set to true to use a secure connection. To do this, check that WinRM is enabled for HTTPS on the target server. The default value is false.

  • SkipCACheck: The Release Management Server and the deployment machine use an SSL connection to communicate if UseHTTPS is set to true. This parameter determines if certificate verification is required to set up this connection. If it is true, the verification is skipped. If it is set to false, a certificate for the deployment machine must be installed.

Q: What are each of the parameters for the Deploy to Azure Environment action?

A: Here are the details:

  • ServerName: Name of the Azure virtual machine where you want to deploy this component.

  • UserName: Account name to connect to the virtual machine. This user must be a domain user and also a member of the Administrators group on the server.

  • Password: Password for the user account.

  • PSScriptPath: Path and filename of PowerShell or DSC script to deploy this component. This path is relative to the package path for the component.

  • PSConfigurationPath: Path and filename of PowerShell or DSC script to configure the VM before deployment of this component. This script is optional. It will be run before the script in the PSScriptPath parameter. This path is relative to the package path for the component.

  • UseHTTPS: This is always set to true for the connection to the Azure VM. A secure connection is always used, so you must check that WinRM is enabled for HTTPS on the virtual machine.

  • SkipCACheck: The Release Management Server and the Azure VM use an SSL connection to communicate because UseHTTPS is always set to true. This parameter determines if certificate verification is required to set up this connection. If it is true, the verification is skipped. If it is set to false, a certificate for the deployment machine must be installed.

Q: What are each of the parameters for the Deploy to Chef action?

A: Here are the details:

  • NodeName: Name of the Chef Node where you want to deploy the application. This must match the name of the server in the on-premises environment.

  • IsUnixNode: Set this parameter to true if it is a UNIX based machine.

  • UserName: Account name to connect to the node. For UNIX based systems this should be a user that has sudo privileges with ssh permissions. For Windows based systems this should be a user with winRM permissions, or a local administrator.

  • Password: Password for the user account.

  • ComponentName: Name of the component to be deployed.

  • AttributeName: Name of the Chef node attribute which is used by the cookbooks to get the application package. Nested attributes are supported. The format of this name is: ['AttributeLevel1']['AttributeLevel2'][...]

  • KnifeInstallationPath: The absolute path to the knife.bat file on the Release Management Server.

  • ChefRepoPath: The absolute path to the chef repo directory on the Release Management Server.
