Chapter 2. Preparing Capsule Servers for load balancing

Procedure

1. In the Satellite web UI, navigate to Hosts > Register Host.
2. From the Capsule dropdown list, select your Capsule Server configured for load balancing.
3. Select Force to register a host that has been previously registered to a Capsule Server.
4. From the Activation Keys list, select the activation keys to assign to your host.
5. Click Generate to create the registration command.
6. Click on the files icon to copy the command to your clipboard.
7. Connect to your host using SSH and run the registration command.
8. Check the /etc/yum.repos.d/redhat.repo file and ensure that the appropriate repositories have been enabled.

CLI procedure

1. Generate the host registration command using the Hammer CLI:

   $ hammer host-registration generate-command \
   --activation-keys "My_Activation_Key"

   If your hosts do not trust the SSL certificate of Satellite Server, you can disable SSL validation by adding the --insecure flag to the registration command.

   $ hammer host-registration generate-command \
   --activation-keys "My_Activation_Key" \
   --insecure true

   Include the --smart-proxy-id My_Capsule_ID option. You can use the ID of any Capsule Server that you configured for host registration load balancing. Satellite will apply the load balancer to the registration command automatically.

   Include the --force option to register a host that has been previously registered to a Capsule Server.

2. Connect to your host using SSH and run the registration command.
3. Check the /etc/yum.repos.d/redhat.repo file and ensure that the appropriate repositories have been enabled.

API procedure

1. Generate the host registration command using the Satellite API:

   # curl -X POST https://satellite.example.com/api/registration_commands \
   --user "My_User_Name" \
   -H 'Content-Type: application/json' \
   -d '{ "registration_command": { "activation_keys": ["My_Activation_Key_1, My_Activation_Key_2"] }}'

   If your hosts do not trust the SSL certificate of Satellite Server, you can disable SSL validation by adding the --insecure flag to the registration command.

   # curl -X POST https://satellite.example.com/api/registration_commands \
   --user "My_User_Name" \
   -H 'Content-Type: application/json' \
   -d '{ "registration_command": { "activation_keys": ["My_Activation_Key_1, My_Activation_Key_2"], "insecure": true }}'

   Use an activation key to simplify specifying the environments. For more information, see Managing Activation Keys in Managing content.

   Include { "smart_proxy_id": My_Capsule_ID }. You can use the ID of any Capsule Server that you configured for host registration load balancing. Satellite will apply the load balancer to the registration command automatically.

   Include { "force": true } to register a host that has been previously registered to a Capsule Server.

   To enter a password as a command line argument, use username:password syntax. Keep in mind this can save the password in the shell history. Alternatively, you can use a temporary personal access token instead of a password. To generate a token in the Satellite web UI, navigate to My Account > Personal Access Tokens.

2. Connect to your host using SSH and run the registration command.
3. Check the /etc/yum.repos.d/redhat.repo file and ensure that the appropriate repositories have been enabled.

Procedure

1. Disable all repositories:

   # subscription-manager repos --disable "*"

2. Enable the following repositories:

   # subscription-manager repos \
   --enable=rhel-9-for-x86_64-baseos-rpms \
   --enable=rhel-9-for-x86_64-appstream-rpms \
   --enable=satellite-capsule-6.17-for-rhel-9-x86_64-rpms \
   --enable=satellite-maintenance-6.17-for-rhel-9-x86_64-rpms

1. Update all packages:

   # dnf upgrade

2. Install the Capsule Server packages:

   # dnf install satellite-capsule
