Managing SUSE Content

You can use the SCC Manager plug-in to manage content from SUSE on your orcharhino.

Running SUSE Linux Enterprise Server on managed hosts requires a subscription from SUSE. Ensure to provide valid licenses for all used SUSE products. Using insufficient, invalid, or otherwise inadequate licenses might violate your terms with SUSE.

We recommend using the SCC Manager plugin to import available products from SUSE to orcharhino. Navigate to Content > SUSE Subscriptions to see available and consumed SUSE subscriptions.

Preparing SUSE Installation Media

Use this procedure to extract the SUSE installation medium on your orcharhino Server to provision hosts in a disconnected environment. This example prepares the installation medium for SUSE Linux Enterprise Server 15 SP3.

Procedure

  1. Download the SLES 15 SP3 installation medium from suse.com/download/sles.

  2. Download the signature and checksum from suse.com.

  3. Transfer the .iso image, the signature, and the checksum from your local machine to orcharhino Server using scp:

    # scp SLE-15-SP3-Full-x86_64-GM-Media1.iso root@orcharhino.example.com:/tmp/
# scp SLE-15-SP3-Full-x86_64-GM-Media1.iso.sha256 root@orcharhino.example.com:/tmp/
# scp sles_15_sp3.signature root@orcharhino.example.com:/tmp/

  4. On your orcharhino Server, verify the integrity and authenticity of the .iso image using GPG public keys:

    # cd /tmp
# gpg --verify sles_15_sp3.signature SLE-15-SP3-Full-x86_64-GM-Media1.iso.sha256
# echo '2a6259fc849fef6ce6701b8505f64f89de0d2882857def1c9e4379d26e74fa56 SLE-15-SP3-Full-x86_64-GM-Media1.iso' | sha256sum --check

  5. Mount the .iso image:

    # mount SLE-15-SP3-Full-x86_64-GM-Media1.iso /mnt

  6. Copy the content of the mounted installation medium to the pub directory:

    # mkdir -p /var/www/html/pub/installation_media/sles/15sp3
# cp -a /mnt/* /var/www/html/pub/installation_media/sles/15sp3/

  7. Unmount and delete the .iso image:

    # cd
# umount /mnt
# rm -f /tmp/SLE-15-SP3-Full-x86_64-GM-Media1.iso
# rm -f /tmp/SLE-15-SP3-Full-x86_64-GM-Media1.iso.sha256
# rm -f /tmp/sles_15_sp3.signature

You can use the path to the local installation media files when creating an installation medium, for example http://orcharhino.example.com/pub/installation_media/sles/15sp3/. For more information, see Adding Installation Media to orcharhino in Provisioning Hosts.

Creating a SUSE Operating System

Use this procedure to create an installation medium and operating system entry for SLES 15 SP3. For more information, see:

Prerequisite

  • An extracted .iso image on orcharhino or an HTTP server that can be reached from hosts during their provisioning process. For more information, see Preparing SUSE Installation Media.

Procedure

  1. In the orcharhino management UI, navigate to Hosts > Installation Media and click Create Medium.

  2. Set a Name for the installation medium for SLES 15 SP3. Add local to the name because the path of the extracted .iso image points to your orcharhino.

  3. Set the Path of the extracted .iso image. The content of /var/www/html/pub/ is publicly available on http://orcharhino.example.com/pub/. If you extract the .iso image to /var/www/html/pub/installation_media/sles/15sp3/, the path is http://orcharhino.example.com/pub/installation_media/sles/15sp3/.

  4. Set the Operating System Family to SUSE for all SLES systems.

  5. Set a location and organization context for the installation media.

  6. On the Parameters tab, add the sle-module-basesystem-url parameter, select the string type, and enter the value http://orcharhino.example.com/pub/installation_media/sles/15sp3/. Note that the value depends on the path of the extracted .iso image.

    Add the or_client_repo_url parameter, select the string type, and enter the value http://orcharhino.example.com/pulp/repos/My_Organization/Library/custom/SLES_Client/SLES_Client_15SP3/.

    If you want to provision hosts through orcharhino Proxies, you have to use the sle-module-basesystem-path and or_client_repo_path parameters containing the Published At paths of your content on orcharhino Server. orcharhino Proxy will add the FQDN of your orcharhino Proxy to generate the URL based on the Content Source setting of your host.

    (SLES 12 only) Add the parameter additional_media, select the string type, and enter the value "".

  7. Click Submit to save the installation media entry for SLES 15 SP3.

  8. In the orcharhino management UI, navigate to Hosts > Operating Systems and click Create Operating System.

  9. Set the Name of the operating system. Choose a name as reported by Ansible, Puppet, or Salt as fact.

  10. Set the Major Version of SLES, for example 15.

  11. Set the Minor Version of SLES, for example 3 for SLES 15 SP3.

  12. Optional: Add an arbitrary Description.

  13. Set the Family to SUSE for all SLES systems.

  14. Set the Root Password Hash to SHA256 for SLES 15 SP3.

  15. Assign the Architectures to SLES 15 SP3.

  16. Click Submit to save the operating system entry.

  17. In the orcharhino management UI, navigate to Hosts > Partition Tables and click Create Partition Table. The partition tables are stored in the /usr/share/foreman/app/views/unattended/partition_tables_templates/ directory on your orcharhino Server.

    For more information, see Partition Tables in Provisioning Hosts.

  18. In the orcharhino management UI, navigate to Hosts > Provisioning Templates and click Create Template. The provisioning templates are stored in the /usr/share/foreman/app/views/unattended/provisioning_templates/ directory on your orcharhino Server.

    For more information, see Provisioning Templates in Provisioning Hosts.

  19. In the orcharhino management UI, navigate to Hosts > Operating Systems.

  20. Select the previously created operating system.

  21. On the Partition Table tab, select the previously created partition table.

  22. On the Templates tab, select the previously created provisioning template.

  23. Click Submit to save the operating system entry.
