Administrator tasks and considerations

This article discusses the tasks and considerations that are relevant for administrators of Citrix Workspace app for iOS.

Feature flag management

If an issue occurs with Citrix Workspace app in production, we can disable an affected feature dynamically in Citrix Workspace app even after the feature is shipped. To do so, we use feature flags and a third-party service called LaunchDarkly. You do not need to make any configurations to enable traffic to LaunchDarkly, except when you have a firewall or proxy blocking outbound traffic. In that case, you enable traffic to LaunchDarkly via specific URLs or IP addresses, depending on your policy requirements.

You can enable traffic and communication to LaunchDarkly in the following ways:

Enable traffic to the following URLs

• app.launchdarkly.com
• events.launchdarkly.com
• stream.launchdarkly.com
• clientstream.launchdarkly.com
• Firehose.launchdarkly.com
• mobile.launchdarkly.com

List IP addresses in an allow list

If you must list IP addresses in an allow list, for a list of all current IP address ranges, see LaunchDarkly public IP list. You can use this list to ensure that your firewall configurations are updated automatically in keeping with the infrastructure updates. For details about the status of the infrastructure changes, see the LaunchDarkly Status page.

LaunchDarkly system requirements

Ensure that the apps can communicate with the following services if you have split tunneling on the Citrix ADC set to OFF for the following services:

• LaunchDarkly service.
• APNs listener service

Provision to disable LaunchDarkly service:

You can disable LaunchDarkly service on both on-premises and cloud stores.

On the cloud setup, administrators can disable the LaunchDarkly service by setting the enableLaunchDarkly attribute to False in the Global App Configuration Service.
