  1. From the left navigation bar, click Settings.

  2. The left side of the Settings window is a set of configurable Authentication settings. Select from the following options:

Different authentication types require you to enter different information. Be sure to include all the information as required.

  1. Click Save to apply the settings or Cancel to abandon the changes.

15.2. Jobs

15.4.1. Usability Analytics and Data Collection

Usability data collection is included with Tower to collect data to better understand how Tower users specifically interact with Tower, to help enhance future releases, and to continue streamlining your user experience.

Only users installing a trial of Tower or a fresh installation of Tower are opted-in for this data collection.

If you want to change how you participate in this analytics collection, you can opt out or change your settings in the User Interface settings, by clicking Settings from the left navigation bar.

Ansible Tower collects user data automatically to help improve the Tower product. You can control the way Tower collects data by setting your participation level in the User Interface settings in the Settings menu.

_images/configure-tower-ui-tracking_state.png
  1. Select the desired level of data collection from the User Analytics Tracking State drop-down list:

  • Off: Prevents any data collection.

  • Anonymous: Enables data collection without your specific user data.

  • Detailed: Enables data collection including your specific user data.

  1. Click Save to apply the settings or Cancel to abandon the changes.

15.4.2. Custom Logos and Images

automation controller supports the use of a custom logo. You can add a custom logo by uploading an image; and supply a custom login message from the User Interface settings of the Settings menu.

_images/configure-tower-ui.png

For the custom logo to look its best, use a .png file with a transparent background. GIF, PNG, and JPEG formats are supported.

If needed, you can add specific information (such as a legal notice or a disclaimer) to a text box in the login modal by adding it to the Custom Login Info text field.

For example, if you uploaded a specific logo, and added the following text:

_images/configure-tower-ui-logo-filled.png

The Tower login dialog would look like this:

_images/configure-tower-ui-angry-spud-login.png

Selecting Revert will result in the appearance of the standard automation controller logo.

15.5. License

Available subscriptions or a subscription manifest authorize the use of Tower. To obtain your Tower subscription, you can either:

  1. Provide your Red Hat or Satellite username and password on the license page.

  2. Obtain a subscriptions manifest from your Subscription Allocations page on the customer portal. See Obtaining a subscriptions manifest in the Automation Controller User Guide for more detail.

If you have a Red Hat Ansible Automation Platform subscription, use your Red Hat customer credentials when you launch Tower to access your subscription information (see instructions below).

If you do not have a Red Hat Ansible Automation Platform subscription, you can request a trial subscription here or click Request Subscription and follow the instructions to request one.

Disconnected environments with Satellite will be able to use the login flow on vm-based installations if they have configured subscription manager on the Tower instance to connect to their Satellite instance. Recommended workarounds for disconnected environments without Satellite include [1] downloading a manifest from access.redhat.com in a connected environment, then uploading it to the disconnected Tower instance, or [2] connecting to the Internet through a proxy server.

Note

In order to use a disconnected environment, it is necessary to have a valid automation controller entitlement attached to your Satellite organization’s manifest. This can be confirmed by using hammer subscription list \--organization <org_name>.

If you have issues with the subscription you have received, please contact your Sales Account Manager or Red Hat Customer Service at https://access.redhat.com/support/contact/customerService/.

When Tower launches for the first time, the Tower Subscription screen automatically displays.

no license

  1. By default, the option to retrieve and import your subscription is to upload a subscription manifest you generate from https://access.redhat.com/management/subscription_allocations. See Obtaining a subscriptions manifest for more detail. Once you have a subscription manifest, you can upload it by browsing to the location where the file is saved (the subscription manifest is the complete .zip file, not its component parts).

Note

If the Browse button in the subscription manifest option is grayed-out, clear the username and password fields to enable the Browse button.

Alternatively, you can choose the option to enter your Red Hat customer credentials using your username and password. Use your Satellite username/password if your Tower cluster nodes are registered to Satellite via Subscription Manager. Once you entered your credentials, click Get Subscriptions.

  1. The subscription metadata is then retrieved from the RHSM/Satellite API, or from the manifest provided.

  • If it is a subscription manifest, and multiple subscription counts were applied in a single installation, Tower will combine the counts but use the earliest expiration date as the expiry (at which point you will need to refresh your subscription).

  • If you entered your credential information (username/password), Tower retrieves your configured subscription service. Then it prompts you to choose the subscription you want to run (the example below shows multiple subscriptions) and entitles Tower with that metadata. You can log in over time and retrieve new subscriptions if you have renewed.

Note

When your subscription expires (you can check this in the Subscription details of the Subscription settings window), you will need to renew it in Tower by one of these two methods.

_images/license-password-entered.png

If you encounter the following error message, you will need the proper permissions required for the Satellite user with which the Tower admin uses to apply a subscription.

_images/tower-license-error-satellite-user.png

The Satellite username/password is used to query the Satellite API for existing subscriptions. From the Satellite API, Tower gets back some metadata about those subscriptions, then filter through to find valid subscriptions that you could apply, which are then displayed as valid subscription options in the UI.

The following Satellite roles grant proper access:

  • Custom with view_subscriptions and view_organizations filter

  • Viewer

  • Administrator

  • Organization Admin

  • Manager

As the Custom role is the most restrictive of these, this is the recommend role to use for your Tower integration. Refer to the Satellite documentation on managing users and roles for more detail.

Note

The System Administrator role is not equivalent to the Administrator user checkbox, and will not provide sufficient permissions to access the subscriptions API page.

  1. Click Next to proceed to Tracking and Insights. Tracking and insights collect data to help Red Hat improve the product by delivering you a much better user experience. For more information about data collection, refer to Usability Analytics and Data Collection. This option is checked by default, but you may opt out of any of the following:

  • User analytics collects data from the Tower User Interface.

  • Insights Analytics provides a high level analysis of your automation with automation controller, which is used to help you identify trends and anomalous use of Tower. For opt-in of Automation Analytics to have any effect, your instance of automation controller must be running on Red Hat Enterprise Linux. See instructions described in the Automation Analytics section. If you select to opt-in for this option, the screen expands and prompts for a username and password to enable Insights, if applicable.

Note

You may change your analytics data collection preferences at any time, as described in the Usability Analytics and Data Collection section.

  1. After you have specified your tracking and insights preferences, click Next to proceed to the End User Agreement.

  2. Review and check the I agree to the End User License Agreement checkbox and click Submit.

Once your subscription has been accepted, Tower briefly displays the subscription details and navigates you to the Dashboard of the automation controller interface. For later reference, you can return to this screen by clicking Settings from the left navigation bar and select Subscription settings from the Subscription option.
