Action Center: Azure PaaS Installation

The Azure installation script enables you to install Action Center on one or multiple nodes.

Important: All the steps in the installation procedures listed below are mandatory.

Before You Begin

Make sure you have the following tools installed on your machine:

• PowerShell Web Deploy Snapin
• PowerShell AzureAZ Module version 7.0 or higher.

Single node installation

Creating the Azure App Service for Action Center

1. Navigate to your Azure Portal and search for App Services.
2. Create a new app service and name it accordingly, for example UiPathActionCenter.
   Note: From the Runtime stack drop-down select .NET Core 3.1.
3. Open the previously created web app and navigate to Configuration > General settings from the left-side menu and set the Platform field to 64 Bit.

Creating the Azure Service Principal for Action Center

1. In the Azure portal, search for App registrations and create a new one, named accordingly.

   Important: You need to assign the Contributor role to the app registration. See here how to do it.

2. On your app's Overview page, copy the Application (client) ID and save it for later use. This is your Azure service principal ID.

   
   

   

   
   

3. On the Clients & secrets page of the previously created app registration, generate a new client secret. Copy its Value and save it for later use. This is your Azure service principal password.

   
   

   

   
   
   Note: Optionally, you can ask your friendly DevOps team to provide you with an Azure service principal ID and password that can access the app service and its associated resource group.

Installing Action Center on Azure

1. Download the UiPathActionCenter.zip archive to your local machine. This contains all the necessary installation scripts.
   Note: UiPath provides the UiPathActionCenter.zip archive on request. Contact us for details.
2. Extract the content of the .zip file to a folder on your machine.
3. Run the Publish-ActionCenter-Azure.ps1 script in PowerShell, using these installation parameters.

   Check out this script example.

4. Enjoy using Action Center on your Azure Portal.

Multi-node Installation

The multi-node installation is similar to the single node installation, with an additional step between steps 6 and 7 of the single node procedure.

Therefore, after step 6, you need to perform the following actions:

• Open the newly created app service.
• Go to the Scale out (App Service plan) tab from the left-side menu.
• Select the Scale to a specific instance count option.
• Provide the desired Instance count.

Continue with step 7 of the single node procedure afterward.

Important:

After migrating or upgrading to Orchestrator 2021.10 PaaS, go to the Azure App Service Configuration and make sure that the following keys are present in the list and their value is set to true:

• IdentityServer.OAuth.Enabled
• IdentityServer.S2SIntegration.Enabled

Storage Buckets Requests

Action Center features that use the storage buckets inside Orchestrator, such as images & PDF rendering on Form actions, Document Classification, and Document Validation actions, require the following configuration in Orchestrator:

To accept Action Center requests to Orchestrator:

• Open the Orchestrator web app in your Azure Portal.
• Navigate to Configuration and select Application Settings.

• Add a New application setting and input the following:

  • Name - AcceptedRootUrls
  • Value - https://localhost:6234,https://<ActionCenterServiceURL>
    Important: Make sure the value entered in the Value field has no empty spaces in it.
    Note: Replace <ActionCenterServiceURL> with the corresponding URL of your Action Center Service.

    

To allow OPTIONS in the web.config file of the Orchestrator web app:

• Open the Orchestrator web app in your Azure Portal.
• Navigate to App Service Editor (Preview).
• Edit the web.config file:
  • Navigate to the <requestFiltering> <verbs> section.
  • Append <add verb="OPTIONS" allowed="true" /> at the end of the section.
    Note: Upgrading Orchestrator resets the web.config file, so you need to allow the OPTIONS verb once again.

    For third party storage providers, read more details about the CORS/CSP Configuration.

Upgrading

To upgrade Azure PaaS Action Center, you need to install a new, higher version that replaces the current one.

Uninstalling

To remove Action Center from your Azure Portal, delete the following Azure resources:

• Action Center app service
• Action Center app registration
