Available subscriptions or a subscription manifest authorize the use of Tower. To obtain your Tower subscription, you can either:
Provide your Red Hat or Satellite username and password on the license page.
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  downloading a manifest from access.redhat.com in a connected environment, then uploading it to the disconnected Tower instance, or  connecting to the Internet through a proxy server.
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.
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).
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.
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.
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.
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.
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:
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.
The System Administrator role is not equivalent to the Administrator user checkbox, and will not provide sufficient permissions to access the subscriptions API page.
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.
You may change your analytics data collection preferences at any time, as described in the Usability Analytics and Data Collection section.
After you have specified your tracking and insights preferences, click Next to proceed to the End User Agreement.
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.
