New Iterate List Action

A new Iterate List action introduced in version 6.0.0.98 allows for iterating a collection of items and calling a designated Action List once for each item in the collection.

The action will iterate any IList<object> collection. The collections to iterate can come from the results of other Actions, such as the Find Files and the Find Services actions. The Set Shared Property action has been extended to include a new Text List type of Shared Property, which can be iterated. And finally, the Iterate List action can be used in conjunction with the C#/VB.Net action, which exposes programmatic access to the entire Shared Properties dictionary, to perform complex repetitive operations during package execution.

Example Usage

To demonstrate the usage of this action, we’ll add 10 sub-directories to our Application Install Directory and add an image file to each one. We’ll start by creating the Action List that will add the files to the designated directory. Note the use of the item Shared Property.

Next, we’ll create the List to iterate. This list will contain the Directory Names for each of the new directories. The Action List will use the current value of the list item to define the directory name. The value is provided to the Action List in the form of a Shared Property (item), who’s key value is defined by the Iterate List action settings.

Finally, we’ll add the Iterate List action to the Primary Action List. Configure it to iterate our list created by the Set Shared Property action and call our specific CreateAndPopulate Action List once for each item.

While the example provided is quite trivial, the demonstrated usage of the Iterate List action will hopefully trigger thoughts on how the action can improve the installation and maintenance of your AppLife managed applications.

Deploying Applications with AppLife Cloud

AppLife provides the ability to easily deploy and maintain many applications on your Windows clients and servers. By installing AppLife Manager on your deployed systems a channel is created with which one or more applications can be deployed and maintained using AppLife packages. This is the first of a series of posts that will discuss and demonstrate the use of AppLife tools to deploy software. This series will include:

  1. Deploying an application with AppLife
    Using mostly default settings, we’ll start from a brand new AppLife subscription and deploy a .NET WPF application through AppLife Manager.
  2. Explore Manager Deployment Options
    After looking at a default deployment in the first post, we’ll demonstrate the different configuration options available with AppLife Manager.
  3. Explore the AppLife Engine
    The deployment package in the first post added two files to the installation directory. In this post, we’ll look at other actions and demonstrate the features of the AppLife Update engine.
  4. Using the Dashboard
    The AppLife Dashboard provides the ability to control which of your deployed systems get applications and updates. It can help in troubleshoot defective packages, can identify which clients are running what version of your applications and more. The final post in the series will look at how the dashboard enhances your AppLife deployment model.

Connecting AppLife Manager to your Subscription

The AppLife Manager application gets installed on all of the systems that will run your software and connects your deployed clients to your AppLife subscription. AppLife Manager is downloaded from AppLife Update home page (www.applifeupdate.com). Once installed, you’ll connect Manager to your subscription through a registration process. To register AppLife Manager, you’ll need your Publisher Code. You’ll also need to define a Client Access Key. The Client Access Key will be a value that identifies an individual client, or perhaps a group of clients.

Your publisher code can be found on the Subscription view of your dashboard and can be replaced with a custom value.

Find your publisher code

Defining a Custom Publisher Code

You can set a custom publisher code for your subscription. One that is more meaningful and easier to remember, such as your domain name. A custom publisher code is set from the Subscription view on your dashboard.

With your publisher code entered, the default settings of your initial application will allow it to be discovered. It’ll be displayed within AppLife Manager. Nothing is actually installed on this deployed client yet, as there are no AppLife packages published for the application.

Deploying an Application

We have an application, called First Look that we want to deploy. We are going to effectively XCopy deploy our First Look application to our client machines through AppLife Manager. To accomplish this, we’ll create and publish an AppLife package that, when executed, will place our application on the deployed client. Once published, AppLife Manager will automatically discover and apply the package.

To create the package, we’ll use the AppLife Builder application. Like AppLife Manager, this can be downloaded from the AppLife Update home page. Once downloaded and installed, log into AppLife using your credentials. Select your subscription application. You’ll be prompted for the basic information about your application.

  1. Application Name
    Set this to your application’s name. In this case, First Look. Note that this will change the name displayed in AppLife Manager.
  2. Executable Name
    Set this to the name of the primary executable of your application. FirstLook.exe.
  3. Local Working Directory
    This is a local value that defines the local directory for your application and will be used for relative paths later. For custom software, this is usually a bin directory or an output directory of your build process.

AppLife Actions

An AppLife Package consists of a series of Actions that will take place when the package is executed on a deployed client. There are many actions available. This first package is going to include only one action. An Add & Replace Files action, which will copy two files to the designated Application Directory. When AppLife Manager discovers and applies this package, these two files will be copied.

By default, AppLife Manager applications will check for new versions every 24 hours. After having published this package, any connected clients will install First Look on their next check. AppLife Manager can also be refreshed manually, which will find the application immediately.

Deployments in the Dashboard

When a client applies an AppLife Package, the results are reported to your dashboard and can be reviewed there.

Summary

Using a new AppLife Subscription, we just built an AppLife Package that deploys our existing application through AppLife Manager. With the exception of setting a custom Publisher Code and changing the application name, we used entirely default settings. In the next post, we’ll explore the configuration options available through AppLife Manager that will let you customize the deployment and maintenance model to better fit different scenarios.
