This article was originally published on the Red Hat Customer Portal. The information may no longer be current.
With the introduction of the newer Systems Management tools such as Satellite 6, we introduced a new concept, the Subscription Manifest (which are different from Satellite 5 Entitlement XML certificates), as the means to import Subscriptions into Satellite for the purposes of synchronizing content and attaching subscriptions to systems.
What is a subscription manifest?
A subscription manifest is a digitally signed zip file containing:
- A listing of subscriptions that can be used by an on-premise subscription management tool (such as Red Hat Satellite)
- Various entitlement certificates associated with those subscriptions usable to download content from the Red Hat Content Delivery Network (CDN).
- A listing of Content Sets (directories on the CDN which access is granted to)
- A x.509 certificate used to authenticate with the Red Hat Customer Portal
- This is used by the Red Hat Insights tool to authenticate when uploading telemetry data
- This is used by Red Hat Satellite to authenticate when downloading updated manifests (using the Refresh manifest button in the UI)
Manifests are to Satellite 6 what XML Entitlement certificates were to Satellite 5.
How do I get a subscription manifest?
Subscription manifests can be created/downloaded via the Customer Portal by visiting https://access.redhat.com -> Subscriptions ->
Subscription Management Applications & selecting either
- Register a Subscription Management Application (for Subscription Asset Manager)
- Register a Satellite (for Satellite 5 & Satellite 6) (Note: This page only appears if you have a valid Satellite subscription)
What is a 'Subscription Management Application'
A 'Subscription Management Application', (occasionally called a 'distributor') is effectively a 'bucket of subscriptions' which have being selected for usage with an on-premise subscription management tool, such as Satellite. Thus, any subscription you wish to use with Satellite needs to be added to a Subscription Management Application first. After creating a Subscription Management Application, one needs to create the Subscription Manifest, which is a signed (thus authoritative) copy of what is actually in the bucket. (at time of signature).
The relationship between the two is similar to 'cargo' (Subscription Management Application) versus 'bill of lading' (Subscription Manifest)
How many subscription manifests do I need?
There is a pretty big difference between Satellite 5 and Satellite 6 with regards to the number of certificates / manifests needed.
Satellite 5 requires:
- A single certificate for the Satellite, which provided entitlements for the entire Satellite, which could be divided into logical organizations for systems management.
The upside to this was that a single certificate supported the entire Satellite. The downside was that is was very difficult to support multiple Red Hat Network Accounts. If you have > 1 Red Hat Network Account you wanted to support with Satellite 5, you had two options:
- Purchase a Satellite for each account.
- Work with your Red Hat account team to transfer subscriptions into a singular account for management.
Neither of these were usually ideal.
Summary: Satellite 5 requires one certificate per installation of Satellite 5.
Satellite 6 requires:
- A single manifest for each organization configured on the Satellite.
The upsides to this model is that since each organization maintains completely separate subscriptions, you can:
- create multiple Subscription Management applications (remember: bucket of sub) supporting multiple organizations.
- support multiple Red Hat Network Accounts
Example follows: In the example above, there are two fictitious customers, ACME Corp and Example Corp, who each wish to leverage the same Satellite 6 installation. Their subscriptions are in two distinct Red Hat Network accounts. In this scenario, ACME Corp can allocate any subset of their 60 subscriptions (in this example, they've allocated 30) to a Subscription Management Application, which can be imported in Example Corp's Satellite as a distinct Organization. This allows ACME's system administrators the ability to manage their systems leveraging Satellite 6 completely independently of Example Corp's 3 organizations (R&D, Operations, and Engineering)
Summary : Satellite 6 requires one manifest per organization. Manifests can be issued from any Red Hat Network Account that has Smart Management subscriptions for the systems that will be managed via Satellite 6
Examining a subscription manifest
Now that we've created a subscription manifest and downloaded it, let's take a look at it. As mentioned above, the subscription manifest is a .zip file, which can be extracted to inspect the various metadata files within. However, included in Red Hat Enterprise Linux is the rct command, part of the subscription-manager package, which allows you to introspect manifests.

When do I need a new subscription manifest?
A new subscription manifest is required whenever the contents of the Subscription Management Application changes OR when the content that the subscriptions provided changes. Examples:
- When Satellite 6.2 was released, updated manifests were required to reflect the new Satellite 6.2 repositories.
- When renewing subscriptions, your new subscriptions need to be added to the Subscription Management Application.
- When adding subscriptions to your Subscription Management Application.
When it is necessary to refresh a manifest, you can do this one of two ways:
- In the UI via the Content->Red Hat Subscriptions->Manage Manifests->Refresh Manifest button.
- By downloading it from the Customer Portal and uploading it in the Satellite user interface.
Connected customers whose Satellites can connect to the Red Hat Customer Portal can use either option. Disconnected customers, whose Satellites cannot connect to the Red Hat Customer Portal can only use the latter option.
Hopefully this document helps to explain what a manifest is, and how they interact with Red Hat Satellite.
