Chapter 3. Managing alternate content sources Alternate content sources define alternate paths to download content during synchronization. The content itself is downloaded from the alternate content source, while the metadata is downloaded from the Satellite Server or the upstream URL, depending on the configuration. You can use alternate content source to speed up synchronization if the content is located on the local filesystem or on a nearby network. You can set up alternate content sources for Satellite Server and Capsule. You must refresh the alternate content source after creation or after making any changes. A weekly cron job refreshes all alternate content sources. You can also refresh the alternate content sources manually by using the Satellite web UI or the Hammer CLI. Alternate content sources associated with your Satellite Server, or Capsule Servers attached to multiple organizations, affect all organizations. There are three types of alternate content sources: Custom Custom alternate content sources download the content from any upstream repository on the network or filesystem. Simplified Simplified alternate content sources copy the upstream repository information from your Satellite Server for the selected products. Simplified alternate content sources are ideal for situations where the connection from your Capsule to the upstream repo is faster than from your Satellite Server. Selecting the Red Hat products when creating a simplified alternate content source will download the content to the Capsules from the Red Hat CDN. RHUI RHUI alternate content sources download content from a Red Hat Update Infrastructure server. Satellite web UI provides examples to help you find the network paths and to import authentication credentials. The RHUI alternate content source must be RHUI version 4 or greater and use the default installation configuration. For example, AWS RHUI is unsupported because it uses an installation scenario with unique authentication requirements. Permission requirements for alternate content sources Non-administrator users must have the below permissions to manage alternate content sources: view_smart_proxies view_content_credentials view_organizations view_products In addition to the above permissions, assign permissions specific to alternate content sources, depending on the actions the users can perform: view_alternate_content_sources create_alternate_content_sources edit_alternate_content_sources destroy_alternate_content_sources 3.1. Configuring custom alternate content sources Prerequisites If the repository requires SSL authentication, import the SSL certificate and key to the Satellite. For more information, see Importing Custom SSL Certificates in Managing content . Note that the alternate content source paths consist of a base URL appended with the subpaths that you provide. For example, if your base URL is https://server.example.com and your subpaths are rhel7/ and rhel8/ , then both https://server.example.com/rhel7/ and https://server.example.com/rhel8/ will be searched. Procedure In the Satellite web UI, navigate to Content > Alternate Content Sources . Click Add Source and set the Source type as Custom . Select the Content type . In the Name field, enter a name for the alternate content source. Optional: In the the Description field, provide a description for the ACS. Select Capsules to which the alternate content source is to be synced. Enter the Base URL of the alternate content source. Enter a comma-separated list of Subpaths. Provide the Manual Authentication or Content Authentication credentials, if these are needed. If SSL verification is required, enable Verify SSL and select the SSL CA certificate. Review details and click Add . Navigate to Content > Alternate Content Sources > click the vertical ellipsis to the newly created alternate content source > Select Refresh . CLI procedure On Satellite Server, enter the following command: Check if the newly created alternate content source is listed: Refresh the alternate content source: Add the Capsules to which the alternate content source is to be synced: Refresh the alternate content sources: 3.2. Configuring simplified alternate content sources Procedure In the Satellite web UI, navigate to Content > Alternate Content Sources . Click Add Source and set the Source type as Simplified . Select the Content type . In the Name field, enter a name for the alternate content source. Optional: In the Description field, provide a description for the ACS. Select Capsules to which the alternate content source is to be synced. Optional: Select Use HTTP proxies if you want the ACS to use the Capsule Server's HTTP proxy. Select the products that should use the alternate content source. Review details and click Add . Navigate to Content > Alternate Content Sources , click the vertical ellipsis to the newly created alternate content source, and select Refresh . CLI procedure Create a simplified ACS: Check if the newly created ACS is listed: Refresh the ACS: 3.2.1. Synchronizing Capsule directly from Red Hat CDN You can use simplified alternate content sources to configure your Capsule to sync content directly from Red Hat CDN. Procedure In the Satellite web UI, navigate to Content > Alternate Content Sources . Click Add Source and set the Source type as Simplified . Set the Content type to Yum . In the Name field, enter a name for the alternate content source. Optional: In the Description field, provide a description for the alternate content source. Select Capsules that you want to sync directly from Red Hat CDN. Optional: Select Use HTTP proxies if you want the ACS to use the Capsule Server's HTTP proxy. Select the Red Hat products that should be synced to the Capsule from Red Hat CDN. Review details and click Add . Navigate to Content > Alternate Content Sources , click the vertical ellipsis to the newly created alternate content source, and select Refresh . The Capsule will now download content from Red Hat CDN and not the Satellite. 3.3. Configuring RHUI alternate content sources Prerequisites Generate the client entitlement certificates for the required repos on the RHUA node as described in Creating a client entitlement certificate with the Red Hat Update Infrastructure Management Tool in Configuring and Managing Red Hat Update Infrastructure . Import the client entitlement certificates into Satellite. For more information, see Importing Custom SSL Certificates in Managing content . Obtain a list of the subpaths for the required repositories. Execute the following command on your RHUA server: Note that the alternate content source paths consist of a base URL appended with the subpaths that you provide. For example, if your base URL is https://server.example.com and your subpaths are rhel7/ and rhel8/ , then both https://server.example.com/rhel7/ and https://server.example.com/rhel8/ will be searched. Procedure In the Satellite web UI, navigate to Content > Alternate Content Sources . Click Add Source and set the Source type as RHUI . Generate RHUI certificates using the command provided in the Satellite web UI. Ensure that you pass the repo labels of the desired repositories. In the Name field, enter a name for the alternate content source. Optional: In the Description field, provide a description for the ACS. Select Capsules to which the alternate content source is to be synced. Optional: Select Use HTTP proxies if you want the ACS to use the Capsule's HTTP proxy. Enter the Base URL of the Red Hat Update Infrastructure CDS node. Enter a comma-separated list of Subpaths. Provide the Content Credentials , if these are needed. If SSL verification is required, enable Verify SSL and select the SSL CA certificate. Review details and click Add . Navigate to Content > Alternate Content Sources , click the vertical ellipsis to the newly created alternate content source, and select Refresh . CLI procedure On Satellite Server, enter the following command: Check if the newly created alternate content source is listed: Refresh the alternate content source: Add the Capsules to which the alternate content source is to be synced: Refresh the alternate content sources:
