Use Satellite 6 as an Inventory Source in Ansible Tower

Welcome to another entry in the Getting Started series! In this post we’ll talk about how to use Red Hat Satellite 6 as an inventory source within Ansible Tower. A common scenario we see is the use of Satellite 6.3 to manage Red Hat Enterprise Linux infrastructure, which makes adding Red Hat Ansible Tower to the existing environment a snap.

First, Create a User in Satellite

Ansible Tower will need to authenticate to Satellite, so create a user with an integration role that has the permissions needed to manage inventory. The permissions needed are:

Resource	Permission	Access Type
Fact value	view_facts	Read Satellite Server facts.
Host	view_hosts	Read Satellite Server hosts.
Host group	view_hostgroups	View Satellite Server host groups.

Once you’ve created your user, log in to the Tower host.

Create Credential in Tower With the Satellite User

Navigate to Settings >> Credentials in Tower and create a new credential.

The credential type can be found in the credential type list:

Once you select ‘Red Hat Satellite 6’, the field to add the Satellite URL will be available:

Add New Inventory

With the Satellite server prepared and the credential in place within Tower, all that’s left is creating the new inventory and setting the source. Navigate to Inventories and add a new inventory:

Give your inventory a name that you’ll remember.

Add Sat6 as the Source

Now to connect to Satellite. In your new inventory, navigate to the Sources tab. You’ll create a Source for the inventory to search:

Like the inventory, set the name and choose the corresponding credential. Choose your verbosity level-- if this is your first time, setting the verbosity higher will give you more information for troubleshooting.

Choose your update options to match your desired behavior. Checking ‘Overwrite’ means that changes in the Satellite inventory will overwrite the inventory in Ansible Tower when synced. If hosts are removed in Satellite, they’ll be removed from Tower when syncing. The ‘Overwrite Variables’ selection covers all groups and hosts within the inventory, with the same behavior as above. If checked, then the Satellite version of variables are written to the Tower inventory. If not checked, the variables are merged from both sources. ‘Update On Launch’ is self-describing in what the option does. When a playbook is run using the inventory, a sync will occur using the options selected.

Once you save the new source, you can click the sync icon to begin the first sync.

That’s it! Now you can use Ansible Tower with the Red Hat Satellite 6 inventory for streamlining your provisioning process using callbacks without managing two separate inventories. Integrating Ansible Tower and Satellite shortens and automates provisioning for your Red Hat products.
