Managing hosts

Procedure

1. In the Satellite web UI, navigate to Hosts > Create Host.
2. On the Host tab, enter the required details.
3. Click the Ansible Roles tab, and from the Ansible Roles list, select one or more roles that you want to add to the host. Use the arrow icon to manage the roles that you add or remove.
4. On the Puppet Classes tab, select the Puppet classes you want to include.

5. On the Interfaces tab:

   1. For each interface, click Edit in the Actions column and configure the following settings as required:

      • Type — For a Bond or BMC interface, use the Type list and select the interface type.
      • MAC address — Enter the MAC address.
      • DNS name — Enter the DNS name that is known to the DNS server. This is used for the host part of the FQDN.
      • Domain — Select the domain name of the provisioning network. This automatically updates the Subnet list with a selection of suitable subnets.
      • IPv4 Subnet — Select an IPv4 subnet for the host from the list.
      • IPv6 Subnet — Select an IPv6 subnet for the host from the list.
      • IPv4 address — If IP address management (IPAM) is enabled for the subnet, the IP address is automatically suggested. Alternatively, you can enter an address. The address can be omitted if provisioning tokens are enabled, if the domain does not manage DNS, if the subnet does not manage reverse DNS, or if the subnet does not manage DHCP reservations.
      • IPv6 address — If IP address management (IPAM) is enabled for the subnet, the IP address is automatically suggested. Alternatively, you can enter an address.
      • Managed — Select this checkbox to configure the interface during provisioning to use the Capsule provided DHCP and DNS services.
      • Primary — Select this checkbox to use the DNS name from this interface as the host portion of the FQDN.
      • Provision — Select this checkbox to use this interface for provisioning. This means TFTP boot will take place using this interface, or in case of image based provisioning, the script to complete the provisioning will be executed through this interface. Note that many provisioning tasks, such as downloading packages by anaconda or Puppet setup in a %post script, will use the primary interface.

      • Virtual NIC — Select this checkbox if this interface is not a physical device. This setting has two options:

        • Tag — Optionally set a VLAN tag. If unset, the tag will be the VLAN ID of the subnet.
        • Attached to — Enter the device name of the interface this virtual interface is attached to.
   2. Click OK to save the interface configuration.
   3. Optionally, click Add Interface to include an additional network interface. For more information, see Chapter 5, Adding network interfaces.

3. Create a "feature" field of the string type with value "katello_package_install".
4. Create a "search_query" field of the string type and input a search query matching the hosts on which you want to install the packages.

5. Optional: If you want to install packages as a specific user, create an ssh object with the following fields of the string type:

   • "effective_user" with the name of the ssh user
   • "effective_user_password" with the password of the ssh user if this password is required

6. Optional: If you want to install packages at a later time, create the "scheduling" object. The object can contain one or both of the following fields of the string type with date, time, and a timezone in the ISO 8601 format:

   • "start_at"- sets the time to install the packages
   • "start_before" - sets the latest time to install the packages. If it is not possible to install the packages by this time, then this action is cancelled.

   If you omit time, it defaults to 00:00:00. If you omit timezone, it defaults to UTC.

7. Optional: If you want to limit the number of hosts on which the job is run concurrently, create the "concurrency_control" object with the "concurrency_level" field of the integer type. Assign the number of hosts as the field value.
8. Optional: If you want to install packages at a later time and you want the host search query to be evaluated at a time of running the job, create a "targeting_type" field of the string type with the "dynamic_query" value. This is useful if you expect the result of the search query to be different at the time of running the job due to changed status of the hosts. If you omit this field, it defaults to "static_query".

9. Send a POST request with the created body to the /api/job_invocations endpoint of your Satellite Server and use a tool like Python to see a formatted response.

   Example API request:

   -u My_Username:My_Password | python3 -m json.tool

Procedure

1. In the Satellite web UI, navigate to Hosts > All Hosts.
2. Click the name of the host you want to modify.
3. Click the Content tab, then click the Packages tab.
4. Select Upgradable from the Status list.
5. Select upgrade version from the dropdown menu in Upgradable to column where applicable.
6. Select the packages you want to upgrade.
7. Click Upgrade. You get a REX job notification once the remote execution job is complete.

API procedure

1. Create the "job_invocation" object and place rest of the body inside this object.
2. Create the "inputs" object with the "package" field of the string type specifying the packages you want to update. If you are specifying multiple packages, separate them with a whitespace.
3. Create a "feature" field of the string type with value "katello_package_update".
4. Create a "search_query" field of the string type and input a search query matching the hosts on which you want to update the packages.

5. Optional: If you want to update packages as a specific user, create an ssh object with the following fields of the string type:

   • "effective_user" with the name of the ssh user
   • "effective_user_password" with the password of the ssh user if this password is required

6. Optional: If you want to update packages at a later time, create the "scheduling" object. The object can contain one or both of the following fields of the string type with date, time, and a timezone in the ISO 8601 format:

   • "start_at"- sets the time to update the packages
   • "start_before" - sets the latest time to update the packages. If it is not possible to update the packages by this time, then this action is cancelled.

   If you omit time, it defaults to 00:00:00. If you omit timezone, it defaults to UTC.

7. Optional: If you want to limit the number of hosts on which the job is run concurrently, create the "concurrency_control" object with the "concurrency_level" field of the integer type. Assign the number of hosts as the field value.
8. Optional: If you want to update packages at a later time and you want the host search query to be evaluated at a time of running the job, create a "targeting_type" field of the string type with the "dynamic_query" value. This is useful if you expect the result of the search query to be different at the time of running the job due to changed status of the hosts. If you omit this field, it defaults to "static_query".

9. Send a POST request with the created body to the /api/job_invocations endpoint of your Satellite Server and use a tool like Python to see a formatted response.

   Example API request:

   curl https://satellite.example.com/api/job_invocations \
   -H "content-type: application/json" \
   -X POST \
   -d @Path_To_My_API_Request_Body \
   -u My_Username:My_Password | python3 -m json.tool

Procedure

2. Click the name of the host you want to modify.
3. Click the Content tab, then click the Packages tab.
4. Click the vertical ellipsis for the package you want to remove and select Remove. You get a REX job notification once the remote execution job is complete.
