The Turbo Hub Server Administration Site enables you to manage and control all aspects of your Turbo Hub Server.

The default location of the Administration Site is: http://localhost:80/admin, and consists of the following links:

  • Hub: This page lists all applications repositories on your Turbo Hub Server. From here Federation can be configured to source application repositories from a master hub. API Keys can be defined to allow access to your hub without using a password (useful for automation, tooling, federation, and other similar scenarios). For more information refer to Managing Hub.

  • Users: This page list all users and groups on your Turbo Hub Server. From here Directory Services can be configured to import users from LDAP or Active Directory. Authentication Method allows you to configure how users will authenticate with the Turbo Hub Server. Device Keys allows you to manage all registered devices. For more information refer to Managing Users and Authentication.

  • Domain: This page lists all servers that are included as part of the current Turbo Hub Server installation. Server settings such as roles, web service bindings, and SSL certificates may be configured here. For more information refer to Managing the Domain.

  • Workspaces: This page lists all workspaces on your Turbo Hub Server. From here workspaces may be added, configured, and deleted. For more information refer to Managing Workspaces.

  • Reports: This page provides preconfigured customizable analytics reports, sorted according to Administration, Hub, and Users. For more information refer to Reports.

  • General: This page contains a summary of your Turbo Hub Server license, and information and options for configuring Turbo Hub Server. For more information refer to Configuration and Customization.

Managing Hub

Server admin hub

All application repositories on Turbo Hub Server are managed from the Hub page of the Administration Site.

Application Repositories

Each new application repository is added to Turbo Hub Server in the form of a Turbo container image, or SVM, which are pushed to the hub using the Turbo Client command line tools. For more information about SVMs and Turbo Virtualization Technology refer to Turbo Server Technology.

Adding a Container Image

Server admin cli push image

Complete the following steps to add a new application image to Turbo Hub Server:

  1. Install the Turbo Client for Windows platform.

  2. Connect the client to your hub server using the turbo config command. See Config Command for more information.

> turbo config --hub=http://[hubserver]
  1. Log in as a hub administrator account or use a system API key. This is done using the turbo login command. See Login Command for more information.
> turbo login admin-user
> turbo login --api-key=6g8BwsIlU7ezl_CMIZ_0PYBwK6WVAUZdx1mxYO1WFOg
  1. Create your container image. See Building Containers for more information on ways to create container images.

As an example, we will make a create an empty container that executes the native notepad.exe application.

> turbo new clean -n=test-container
(exit the container window that is shown)
> turbo commit test-container test/notepad:1.0 --no-base --startup-file=notepad.exe
> turbo push test/notepad:1.0

You will now see your test image in your hub list in the administration site. This image will be accessible to all users who are defined to have access to the hub server.

NOTE: If you do not specify a namespace in the image name (ex, "test" in "test/notepad") then the image will be pushed to the user's private namespace. This image will only be accessible by the user who pushed it and it will not show in the hub list on the administration site.


The push command is denied with following error message:

> turbo push mozilla/firefox-base:68.0.1
Pushing image mozilla/firefox-base:68.0.1 to mozilla/firefox-base:68.0.1
Error: Push failed. This user may not be authorized to push to the mozilla repository.

The current logged in user may not be an administrator of the Hub server. Add the user to the administrators group. For more information refer to Managing Users and Authentication.

NOTE: If you add the user to the administrators group after already attempting to push an image to the Hub server, you may have to wait up to 5 minutes for the permissions to propagate to the Hub server. Either switch to an API key based login, or restart the Hub server process and try again.

Managing Repositories

Server admin edit repository

On the repository edit page, a repository display name can be modified. This shows up in the hub administration page list. The repository ID field cannot be modified and is assigned when the first container image is pushed to the hub. The versions list shows all available images that are available for this repository. They can be referenced by their tag or their ID (ex, "mozilla/firefox:64.0" or "mozilla/firefox#44397e23bf46a08a8a567ba13b2c215668d451c9dde41b030706779dc977cc02"). Accessing a repository without a tag or ID will use the latest available image (ex, "mozilla/firefox"). Note that any repository updates may take up to 24hrs to be automatically retrieved by the Turbo Client.

Importing Repositories

Server admin import repository

With the Import Repository feature, you can import repositories from an external Hub server, such as the Hub, into your local Turbo Server Hub. To import a repository, click the Add Repository dropdown on the Hub page and click Import Repository. The import page has the following options available:

  • Hub Source URL: The Hub server from which the repository will be imported. By default only is available, however if you have domain federation enabled the source domain will also be available.
  • API Key: The API key used to access private repositories from the source Hub. This field is not required for public repositories.
  • Repository Id: The name of the external repository. For example, mozilla/firefox.
  • Revision History Length: The number of application revisions to pull from the remote repository. The default value is 1 revision.

After setting the properties, click Import. The import may take a few minutes to complete depending on the size of the repository. After the import is complete you will see the new repository in your main repository list on the Hub administration page.

Managing API Keys

Server admin API keys

API Keys allow you to login to your hub with a code other than with a username/password. This is useful when configuring automation or in other scenarios where a plain text password is not desirable. If an API Key has been compromised, it can be refreshed to a new value or deleted to immediately revoke access.

Server admin add API key

When adding an API Key, give it a name that describes the general usage of the key. It is also recommended to have distinct keys for distinct usages so that if one is compromised or updated, all usages will not require update. Run as System controls whether the key is given administrative privileges to push new images or delete repositories. Without this setting, the API key will only have read access to repositories.

Managing Users and Authentication

Server admin users

Turbo Hub Server users are tracked and managed via the Administration Site. Users are entered manually or via automated import from LDAP or Active Directory directory services. Users and user groups can be viewed and managed on the Users page. From this page you can view user directories, status, and available actions. Displayed above the user list is the total number of licenses available and the number of licenses currently in use.

Managing Users

Server admin edit user

To manage a user, select the user name from the list on the Users page. The following fields are displayed on the page:

  • Name: Full name of the user.

  • Login Name: The unique login name for the user.

  • Enabled: Determines whether a user can access Turbo Hub Server. After a user is disabled he no longer consumes a seat.

Managing User Groups

Server admin edit user group

To create a user group select Add Group. The Add User Group screen displays. This screen contains the following fields:

  • Name: The group name that displayed on the user screen.

  • Description: A group description (optional).

  • Members: Users and groups that are members of this group. Users and groups are inherited when including other groups as members. Add users or other groups by selecting Add Members.

There are three special groups that are created automatically, Administrators, Anonymous Users, and Everyone:

  • Administrators: This group will be able to log into the administration site and push shared images. Note that changes to the Administrators group will require a service restart before they are honored by the hub services. Access to the administration site will be honored immediately.

  • Anonymous: This group automatically includes any user discovered when the authentication mode is set to Anonymous.

  • Everyone: This group automatically includes all users regardless of authentication mode.

Adding an External Directory Service

Server admin add directory service

Using Turbo Hub Server you can add an external directory service, such as Active Directory. This enables you to manage users with the touch of a button and easily import existing users and groups into Turbo Hub Server. Complete the following steps to add an external directory service:

  1. Open a Turbo Server administration site page in your web browser.

  2. Choose the Users category from the top navigation bar.

  3. Select Manage Directory Services.

  4. Select Add Service. The Add Directory Service screen displays.

  5. Enter your specific settings into Turbo Server. Each section is detailed below.

Note: When synchronizing external directory-services containing of over 5,000 users, the command-line administration utility should be used instead of the Administrator web site. For more information on using the administration utility, see Manage Turbo Server from the Command Line. Synchronizing large directory services uses up to 1 GB memory per 500,000 users and groups on the hub server. Ensure that your hub server has enough memory to handle ordinary load when the directory service sync is running.




This field indicates which service is being added or controlled by the entry. The Name field must not be the same as the service or server you are using.


Administrators can include a description of the directory service being added, which can be helpful in recording notes about the service.

Login Prefix

Login prefixes are given to each user in the directory service to use when they log into the server and are helpful in distinguishing users across different directories. For example, if the directory's login prefix is "acme" and the users name is "aaron", they would log on using the full name "acme\aaron." Once this login prefix is chosen for a directory, it cannot be changed. If you must change the login prefix, the directory service can be deleted and a new one added for the same directory; settings for all users from that directory are lost.

Type In the Type section you can choose the type of the directory service from which to import users and groups.
There is variability in location, security, and schema settings for directory services. Turbo Hub Server provides two templates: Active Directory and Other LDAP. The local Active Directory can be found by selecting Try Local. When found, working connection settings are set automatically.
To synchronize with the local Microsoft Windows domain's Active Directory service, select Try Local. This loads default settings into the Connection and Directory Schema fields. For large directories this can take several minutes.
If the operation is unsuccessful, continue to the Choosing Your Connection Settings section.
If the operation is successful, continue to the Choosing the Directories to Synchronize section.

This section can be used to specify your connection settings to the LDAP directory you are trying to connect to.

For more on this section, scroll down on this page to Choosing Your Connection Settings

Binding Type

This field is used to specify the form of security being employed by the LDAP server you are connecting to.

If "Default" is chosen for Port in the Server section, changing the Binding Type will automatically change the port to the standard LDAP port number for that setting.

Synchronization Account This field specifies the account to use when synchronizing users with the directory services. For more information, scroll down on this page to Choosing Your Connection Settings.
Directory Schema  Allows the administrator to specify which names in the LDAP directory will be imported into the Turbo Hub Server user information. For more information, see Directory Schema, further down this page
Synchronized Items Used to identify items in the directory tree that should be synchronized with Turbo Hub Server. For more information, see Choosing Items to Synchronize, further down this page.

Choosing Your Connection Settings

Complete the following steps to choose your connection settings:

  1. Enter the settings for the Server section. The Host, Port, and Top directory are initialized with typical values, but you can customize them to match your directory service settings. They are best discovered using the management tools for the application that hosts them, such as Microsoft Windows or Apache Directory Services.

    • The Top directory should be specified to avoid potential login issues that are difficult to troubleshoot.
  2. Set the Binding Type. Changing the Binding Type will change the Port to the standard LDAP port number for that setting, if you have not specified another port number.

    • Choosing the Simple binding type is not recommended if you are binding to Active Directory, but it can be useful while on the page in diagnosing connection problems via the Test button.
  3. Enter your credentials at the Synchronization Account section. To connect with a specific account in the Synchronization Account section, specify the username:

    • Active Directory: The domain login (e.g. acme\aaron)

    • Generic LDAP: The distinguished name (e.g. uid=aaron,ou=acme,ou=system)

  4. To test these settings, click on the Test button.

  5. Once the test is successful, proceed to the Directory Schema section.

Directory Schema

Directory schema settings are customizable within any directory service; you can change these settings to match the names in your directory service. The most common schema values are tried by selecting Discover. You can select Discover when you are not satisfied with the result in the Synchronized Directories section. Complete the following steps to use the Discover functionality:

  1. Select Refresh from the Synchronized Directories section and inspect the results. If the users and groups shown there are accurate, leave the directory schema settings as they are.

  2. If the Synchronized Directories does not accurately depict the users and groups you expect, select Discover and wait for the schema settings text boxes to fill with the recommended values. Test these values at any time from using Refresh in the Synchronized Directories section.

  3. If you know the correct schema name for the given properties, you can enter it manually. If there are more than one name for the same value you can enter each name separated by a semicolon. Each is searched during synchronization.

  4. To reset the settings to the Turbo Server default, select Defaults.

Choosing Items to Synchronize

You may limit the scope of users and groups that will be synchronized from your directory service, either by choosing specific directories within the service, or by selecting the user groups in which you are interested.

Choosing directories

Your directory service might contain some subdirectories that have useful information and others that contain unwanted information. You can choose which subdirectories to synchronize using Synchronized Items, selecting the Directories option. Complete the following steps to use Synchronized Items:

  1. Select Refresh to use the current connection and directory schema settings to scan your directory service. Information about discovered sub-directories is available via tooltip popups. For large directories this operation can take several seconds to complete.

  2. To narrow the scope of your synchronization to specific directories complete the following:

    a. Uncheck Include All.

    b. Check directories to include.

Choosing groups

You may have a specific subset of existing users that will use Turbo Server, in a group or groups native to your directory service. You can choose which groups to synchronize using Synchronized Items, selecting the Groups option. Complete the following steps to use Synchronized Items:

  1. Select Refresh to use the current connection and directory schema settings to scan your directory service. Information about discovered group is available via tooltip popups. For large directories this operation can take several seconds to complete.

  2. To narrow the scope of your synchronization to specific groups complete the following:

    a. Uncheck Include All.

    b. Check groups to include. All members of that group will be synchronized, including contained groups and all of their members.

When you are satisfied with your settings, select Save. At this point, the users and groups in your directory service are not synchronized with Turbo Server. From the Manage Directory Services page, click the synchronization button and verify there are positive counts for users and/or groups when it has finished. For large directories this can take several seconds.

Authentication Method

Server admin authentication method

The Authentication Method page configures which Authentication Method is used when an end-user logs into the Hub Site and Turbo Client. The supported methods are:

  • Anonymous: Anonymous authentication allows users to access the Portal without logging in. All anonymous users are added to the Anonymous Users group.

  • Username and Password: Username and Password authentication requires users to provide their username and password in order to log in. Passwords may be managed from the user settings page.

  • Single Sign-On: Single Sign-On authentication allows users to login to external directory services such as Azure AD. For more information on configuring SSO, refer to Configure Azure AD

Device Keys

Server admin device keys

The Device Keys page lists all devices that are registered to the Hub Server. Devices are automatically registered with the Hub Server when subscribing or installing applications. Device Keys may be deleted in order to immediately revoke that device's access to the Hub Server.

Managing the Domain

Server admin domain

The Domain page lists all servers that are included as part of the current Turbo Server installation, along with their current status. Clicking a server name will navigate to the server configuration page.

Domain Settings

Server admin domain settings

The Settings page lists allows you to configure domain-wide settings, including:

  • Domain URL: A URL or DNS hostname of the domain that hosts all Turbo Server web services. For more information, see Understanding the Domain URL

  • Resource Allocation Strategy: The load balancing strategy used to allocate applications to application servers. The available strategies are:

    • Active Sessions: New application requests will be allocated to the active application server with the lowest active session count.
    • Total Sessions: New application requests will be allocated to the active application server with the lowest total session count.
    • CPU Load: New application requests will be allocated to the active application server with the lowest CPU load.
  • Default Launch Mode: The default launch location used when launching applications from the dashboard. If an application is configured with its own launch location, that setting will take precedence. The available options are:

    • Run in Cloud (HTML5): Application launches will open a new browser tab to which the application will stream from the application server.
    • Run in Cloud (Windowed): Application Launches will open a new browser tab and attempt an auto-launch. If a native client is installed, the application will stream from the application server.
    • Run on My PC (Local): Application Launches will open a new browser tab and attempt an auto-launch. If a native client is installed, the application will run on the local machine.

Domain Federation

Server admin domain federation

The Federation page allows you to configure federation across multiple domains to reduce setup time and keep domain resources in sync. According to these settings, the server will will periodically check the source domain for updates and replicate any changes.

A domain federated server replicates the source server's workspaces, workspace permissions, and the workspaces' associated image repositories. In addition, the source server's users, groups, directory services, and identity method are also replicated to allow the users to run applications from workspaces using the same login identity. If the identity method is an external authentication method such as Azure AD, the subdomain's redirect url must be added in the Azure Portal.

If an existing login name or built in group, directory service, or user exists on the server, it will not be replicated. For example, the built in SYSTEM user will not be replicated. Replicated users will automatically belong to the 'Everyone' built in user group, but not the Anonymous or Administrator built in user groups.

If an existing workspace with the same url friendly ID exists on the subdomain, it will be overwritten. If the source workspace permission references a built in group (Anonymous, Administrators, or Everyone), it will be normalized to reference the subdomain's built in group and automatically apply to the users belonging to those groups.

The available configurations are described below:

  • Source Domain URL: A federation source URL from which domain resources will be replicated.

  • System API Key: The API key used to access federation resources from the federation source. This API key must be configured as a system-level key on the source server. See Managing API Keys for information on configured API keys.

  • Default Synchronization Frequency: The frequency at which this server will check the federation source for updates.

  • Identity: Federate identity data from the source domain, including users, groups, directory services, and authentication settings.

  • Workspaces: Federate selected workspaces from the source domain. All repositories associated with the selected workspaces will also be federated.

  • Request Forwarding: Automatically pull repositories from the federated domain when a local repository is not found.

  • Revision History Length: Number of application revisions to pull from the remote repository.

Managing a Server

Server admin domain server settings

  • Name: A display name for the server, shown in the Administration Site.

  • Role: The roles for which this server is responsible, including: Hub Server, Hub Site (Portal), and Application Server. Changing the server role will trigger a service restart which may take a few minutes to complete.

  • Use Advanced Video Coding: Enables the use of Advanced Video Coding (H.264) for remote application streaming if the Application Server supports it. This setting is only available for servers with the Application role enabled.

  • Web Service Root: Configures the web service bindings for where the hub, portal, broker, and public web services will be hosted. This setting is only available for servers with the Hub or Portal role enabled.

  • Web Service SSL Certificate: Configures the SSL certificate files that are used for HTTPS web service bindings. The provided file paths must point to permanent locations that are available to the service account.

  • Java Virtual Machine Settings: Configures the JVM heap space for the Hub and Broker Java processes. This setting is only available for servers with the Hub or Portal roles enabled.

  • Image Cache: Configures an image cache path where the Hub will store SVM images. This prevents the redownload of the same application when ran by different users. This can be a local file path which will be shared by all users on the same device, or a network path which may be shared by all users across multiple devices. This setting is only available for servers with the Hub role enabled.

  • Configuration API Key: The API key used by the Launch Configuration Service to post custom application configurations. Configurations posted with this API key are publicly accessibly. This setting is recommended if you will be using an external portal instead of the Turbo Portal. This setting is only available for servers with the Portal role enabled.

  • Configuration Cache Expiration: The length of time (in milliseconds) that a configuration is valid after it is added to the launch configuration service. This timeout is reset any time the application configuration is accessed, such as during an application launch. This setting is only available for servers with the Portal role enabled.

Managing Workspaces

Server admin workspaces

A workspace defines a set of applications and user permissions. These workspaces are shown on the Turbo Streaming Server portal and on the Turbo Clients to users with sufficient permissions. By default there is a single Default Workspace with User permissions granted to the Everyone user group, allowing access to all users. Applications, permissions, and analytics can be managed from the the Workspace Administration page.

Server Administrators, as well as users with Administrator permissions to the workspace, may click the Manage button to access the Workspace Administration site.

Workspace Administration Dashboard
