Configuring provisioning resources

Provisioning contexts

A provisioning context is the combination of an organization and location that you specify for orcharhino components. The organization and location that a component belongs to sets the ownership and access for that component.

Organizations divide orcharhino components into logical groups based on ownership, purpose, content, security level, and other divisions. You can create and manage multiple organizations through orcharhino and assign components to each individual organization. This ensures orcharhino Server provisions hosts within a certain organization and only uses components that are assigned to that organization. For more information about organizations, see Managing Organizations in Managing Organizations and Locations.

Locations function similar to organizations. The difference is that locations are based on physical or geographical setting. Users can nest locations in a hierarchy. For more information about locations, see Managing Locations in Managing Organizations and Locations.

Setting the provisioning context

When you set a provisioning context, you define which organization and location to use for provisioning hosts.

The organization and location menus are located in the menu bar, on the upper left of the orcharhino management UI. If you have not selected an organization and location to use, the menu displays: Any Organization and Any Location.

Procedure

  1. Click Any Organization and select the organization.

  2. Click Any Location and select the location to use.

Each user can set their default provisioning context in their account settings. Click the user name in the upper right of the orcharhino management UI and select My account to edit your user account settings.

CLI procedure

  • When using the CLI, include either --organization or --organization-label and --location or --location-id as an option. For example:

    # hammer host list --organization "My_Organization" --location "My_Location"

    This command outputs hosts allocated to My_Organization and My_Location.

Creating operating systems

An operating system is a collection of resources that define how orcharhino Server installs a base operating system on a host. Operating system entries combine previously defined resources, such as installation media, partition tables, provisioning templates, and others.

You can add operating systems using the following procedure. To use the CLI instead of the orcharhino management UI, see the CLI procedure.

You can use a script to add operating system entries to your orcharhino Server.

On your orcharhino Server, uncomment the operating systems and orcharhino Client for Ubuntu that you want to add in /etc/orcharhino-ansible/or_operating_systems_vars.yaml, replace the default organization and location names, and run /opt/orcharhino/automation/play_operating_systems.sh. For more information, see /usr/share/orcharhino-ansible/README.md on your orcharhino Server.
Procedure

  1. In the orcharhino management UI, navigate to Hosts > Operating systems and click New Operating system.

  2. In the Name field, enter a name to represent the operating system entry.

  3. In the Major field, enter the number that corresponds to the major version of the operating system.

  4. In the Minor field, enter the number that corresponds to the minor version of the operating system.

  5. In the Description field, enter a description of the operating system.

  6. From the Family list, select the operating system’s family.

  7. From the Root Password Hash list, select the encoding method for the root password.

  8. From the Architectures list, select the architectures that the operating system uses.

  9. Click the Partition table tab and select the possible partition tables that apply to this operating system.

  10. Click the Installation Media tab and enter the information for the installation media source. For more information, see Adding Installation Media to orcharhino.

  11. Click the Templates tab and select a PXELinux template, a Provisioning template, and a Finish template for your operating system to use. You can select other templates, for example an iPXE template, if you plan to use iPXE for provisioning.

  12. On the Parameters tab, 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/My_OS_Client/My_OS_Client_Version/.

    If you want to provision hosts through orcharhino Proxies, you have to use the or_client_repo_path parameter containing the Published At path 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.

  13. Click Submit to save your provisioning template.

CLI procedure

  • Create the operating system using the hammer os create command:

    # hammer os create \
--architectures "x86_64" \
--description "My_Custom_Operating_System" \
--family "Debian" \
--major 22.04 \
--media "Debian" \
--minor 1 \
--name "Ubuntu" \
--partition-tables "My_Partitioning_Table" \
--provisioning-templates "My_Provisioning_Template"

Creating an operating system for Ubuntu

Create an operating system in orcharhino to provision hosts running Ubuntu. This example creates an operating system entry for Ubuntu 22.04.1.

You can use a script to add operating system entries to your orcharhino Server.

On your orcharhino Server, uncomment the operating systems and orcharhino Client for Ubuntu that you want to add in /etc/orcharhino-ansible/or_operating_systems_vars.yaml, replace the default organization and location names, and run /opt/orcharhino/automation/play_operating_systems.sh. For more information, see /usr/share/orcharhino-ansible/README.md on your orcharhino Server.
Procedure

  1. In the orcharhino management UI, navigate to Hosts > Provisioning Setup > Operating Systems.

  2. Click Create Operating System to create an operating system entry for Ubuntu.

  3. Enter Ubuntu 22.04 as Name for the operating system. Choose a name as reported by Ansible, Puppet, or Salt as fact.

  4. Set the Major Version to 22.04.

  5. Set the Minor Version to 1.

    orcharhino searches for the boot files in the installation medium depending on the major and minor version of the operating system. Ensure to enter both the major and minor version correctly.

    For example, for Ubuntu 22.04, set the major field to 22.04 and leave the minor field empty. For example, for Ubuntu 22.04.1, set the major field to 22.04 and the minor field to 1.

  6. Set the Release Name to Jammy Jellyfish for Ubuntu 22.04.

  7. On the Partition Table tab, select the Preseed partition table.

    For more information, see creating partition tables.

  8. On the Templates tab, select the Preseed Finish template as Finish template, the Preseed template as Provisioning Template, and the Preseed PXELinux template as PXELinux template.

  9. On the Parameters tab, 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/Ubuntu_Client/Ubuntu_Client_22.04/.

    If you want to provision hosts through orcharhino Proxies, you have to use the or_client_repo_path parameter containing the Published At path 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.

    For more information, see creating provisioning templates.

  10. Click Submit to save the operating system entry for Ubuntu.

Updating the details of multiple operating systems

Use this procedure to update the details of multiple operating systems. This example shows you how to assign each operating system a partition table called Kickstart default, a configuration template called Kickstart default PXELinux, and a provisioning template called Kickstart Default.

Procedure

  1. On orcharhino Server, run the following Bash script:

    PARTID=$(hammer --csv partition-table list | grep "Kickstart default," | cut -d, -f1)
PXEID=$(hammer --csv template list --per-page=1000 | grep "Kickstart default PXELinux" | cut -d, -f1)
SATID=$(hammer --csv template list --per-page=1000 | grep "provision" | grep ",Kickstart default" | cut -d, -f1)

for i in $(hammer --no-headers --csv os list | awk -F, {'print $1'})
do
   hammer partition-table add-operatingsystem --id="${PARTID}" --operatingsystem-id="${i}"
   hammer template add-operatingsystem --id="${PXEID}" --operatingsystem-id="${i}"
   hammer os set-default-template --id="${i}" --config-template-id=${PXEID}
   hammer os add-config-template --id="${i}" --config-template-id=${SATID}
   hammer os set-default-template --id="${i}" --config-template-id=${SATID}
done

  2. Display information about the updated operating system to verify that the operating system is updated correctly:

    # hammer os info --id 1

Creating architectures

An architecture in orcharhino represents a logical grouping of hosts and operating systems. Architectures are created by orcharhino automatically when hosts check in with Puppet. Basic i386 and x86_64 architectures are already preset in orcharhino.

Use this procedure to create an architecture in orcharhino.

Procedure

  1. In the orcharhino management UI, navigate to Hosts > Provisioning Setup > Architectures.

  2. Click Create Architecture.

  3. In the Name field, enter a name for the architecture.

  4. From the Operating Systems list, select an operating system. If none are available, you can create and assign them under Hosts > Provisioning Setup > Operating Systems.

  5. Click Submit.

CLI procedure

  • Enter the hammer architecture create command to create an architecture. Specify its name and operating systems that include this architecture:

    # hammer architecture create \
--name "My_Architecture" \
--operatingsystems "My_Operating_System"

Creating hardware models

Use this procedure to create a hardware model in orcharhino so that you can specify which hardware model a host uses.

Procedure

  1. In the orcharhino management UI, navigate to Hosts > Provisioning Setup > Hardware Models.

  2. Click Create Model.

  3. In the Name field, enter a name for the hardware model.

  4. Optionally, in the Hardware Model and Vendor Class fields, you can enter corresponding information for your system.

  5. In the Info field, enter a description of the hardware model.

  6. Click Submit to save your hardware model.

CLI procedure

  • Create a hardware model using the hammer model create command. The only required parameter is --name. Optionally, enter the hardware model with the --hardware-model option, a vendor class with the --vendor-class option, and a description with the --info option:

    # hammer model create \
--hardware-model "My_Hardware_Model" \
--info "My_Description" \
--name "My_Hardware_Model_Name" \
--vendor-class "My_Vendor_Class"

Adding installation media to orcharhino

Installation media are sources of packages that orcharhino Server uses to install a base operating system on a machine from an external repository.

You can view installation media by navigating to Hosts > Provisioning Setup > Installation Media.

Installation media must be in the format of an operating system installation tree and must be accessible from the machine hosting the installer through an HTTP URL.

If you want to improve download performance when using installation media to install operating systems on multiple hosts, you must modify the Path of the installation medium to point to the closest mirror or a local copy.

To use the CLI instead of the orcharhino management UI, see the CLI procedure.

Procedure

  1. In the orcharhino management UI, navigate to Hosts > Provisioning Setup > Installation Media.

  2. Click Create Medium.

  3. In the Name field, enter a name to represent the installation media entry.

  4. In the Path enter the URL that contains the installation tree.

  5. From the Operating system family list, select the distribution or family of the installation medium. Ubuntu belongs to the Debian family.

  6. Click the Organizations and Locations tabs, to change the provisioning context. orcharhino Server adds the installation medium to the set provisioning context.

  7. Click Submit to save your installation medium.

ATIX AG provides file repositories for installation media. You can synchronize them to provision hosts in disconnected environments by using local installation media. For a list of upstream URLs, see Using file repositories for installation media for Debian/Ubuntu in the ATIX Service Portal.

ATIX AG provides the following installation media as file repository:

  • Debian 9

  • Debian 10

  • Debian 11

  • Debian 12

  • Ubuntu 18.04

  • Ubuntu 20.04

  • Ubuntu 22.04
CLI procedure

  • Create the installation medium using the hammer medium create command:

    # hammer medium create \
--locations "My_Location" \
--name "My_OS" \
--organizations "My_Organization" \
--os-family "Debian" \
--path "http://download.example.com/ubuntu/22.04.1/"

Creating an installation medium for Ubuntu

Create an installation medium in orcharhino to provision hosts running Ubuntu.

You can use a script to add operating system entries to your orcharhino Server.

On your orcharhino Server, uncomment the operating systems and orcharhino Client for Ubuntu that you want to add in /etc/orcharhino-ansible/or_operating_systems_vars.yaml, replace the default organization and location names, and run /opt/orcharhino/automation/play_operating_systems.sh. For more information, see /usr/share/orcharhino-ansible/README.md on your orcharhino Server.
Procedure

  1. In the orcharhino management UI, navigate to Hosts > Provisioning Setup > Installation Media.

  2. Click Create Medium to create an installation medium entry.

  3. Enter a Name for the installation medium.

  4. Set the Path to the upstream URL http://ftp.ubuntu.com/ubuntu/.

    Alternatively, you can also use a Ubuntu Mirror. Note that synchronized content from orcharhino does not work for two reasons: first, the linux and initrd.gz files are not synchronized; second, the Release file is not signed with the official Ubuntu GPG private key.

  5. Set the Operating System Family to Debian.

  6. Click Submit to save the installation medium to orcharhino.

Associating Templates to an Operating System

Associate the previously created partition table and provisioning templates with the Ubuntu 22.04 operating system.

Procedure

  1. Navigate to Hosts > Operating Systems.

  2. Select the Ubuntu 22.04 operating system.

  3. On the Partition Table tab, select your previously created Preseed partition table as Partition Table.

  4. On the Templates tab, select your previously created Preseed Finish template as Finish template, Preseed template as Provisioning Template, and Preseed PXELinux template as PXELinux template.

  5. Click Submit to associate the partition table and provisioning templates with Ubuntu 22.04.

For Ubuntu 22.04 "Jammy", select Preseed default PXELinux Autoinstall as PXELinux template, Preseed Autoinstall cloud-init user data as User data template, and Preseed orcharhino finish as Finish template.

Creating partition tables

A partition table is a type of template that defines the way orcharhino Server configures the disks available on a new host. A Partition table uses the same ERB syntax as provisioning templates. orcharhino contains a set of default partition tables to use, including a Preseed default. You can also edit partition table entries to configure the preferred partitioning scheme, or create a partition table entry and add it to the operating system entry.

To use the CLI instead of the orcharhino management UI, see the CLI procedure.

Procedure

  1. In the orcharhino management UI, navigate to Hosts > Templates > Partition Tables.

  2. Click Create Partition Table.

  3. In the Name field, enter a name for the partition table.

  4. Select the Default checkbox if you want to set the template to automatically associate with new organizations or locations.

  5. Select the Snippet checkbox if you want to identify the template as a reusable snippet for other partition tables.

  6. From the Operating System Family list, select the distribution or family of the partitioning layout. Ubuntu belongs to the Debian family.

  7. In the Template editor field, enter the layout for the disk partition. For example:

    zerombr
clearpart --all --initlabel
autopart

    You can also use the Template file browser to upload a template file.

    The format of the layout must match that for the intended operating system. For example, Ubuntu requires a layout that matches a Preseed file.

  8. In the Audit Comment field, add a summary of changes to the partition layout.

  9. Click the Organizations and Locations tabs to add any other provisioning contexts that you want to associate with the partition table. orcharhino adds the partition table to the current provisioning context.

  10. Click Submit to save your partition table.

CLI procedure

  1. Before you create a partition table with the CLI, create a plain text file that contains the partition layout. This example uses the ~/My_Partition_Table file.

  2. Create the installation medium using the hammer partition-table create command:

    # hammer partition-table create \
--file "~/My_Partition_Table" \
--locations "My_Location" \
--name "My_Partition_Table" \
--organizations "My_Organization" \
--os-family "Debian" \
--snippet false

Dynamic partition example

Using an Anaconda kickstart template, the following section instructs Anaconda to erase the whole disk, automatically partition, enlarge one partition to maximum size, and then proceed to the next sequence of events in the provisioning process:

zerombr
clearpart --all --initlabel
autopart <%= host_param('autopart_options') %>

Dynamic partitioning is executed by the installation program. Therefore, you can write your own rules to specify how you want to partition disks according to runtime information from the node, for example, disk sizes, number of drives, vendor, or manufacturer.

If you want to provision servers and use dynamic partitioning, add the following example as a template. When the #Dynamic entry is included, the content of the template loads into a %pre shell scriplet and creates a /tmp/diskpart.cfg that is then included into the Kickstart partitioning section.

#Dynamic (do not remove this line)

MEMORY=$((`grep MemTotal: /proc/meminfo | sed 's/^MemTotal: *//'|sed 's/ .*//'` / 1024))
if [ "$MEMORY" -lt 2048 ]; then
    SWAP_MEMORY=$(($MEMORY * 2))
elif [ "$MEMORY" -lt 8192 ]; then
    SWAP_MEMORY=$MEMORY
elif [ "$MEMORY" -lt 65536 ]; then
    SWAP_MEMORY=$(($MEMORY / 2))
else
    SWAP_MEMORY=32768
fi

cat <<EOF > /tmp/diskpart.cfg
zerombr yes
clearpart --all --initlabel
part /boot --fstype ext4 --size 200 --asprimary
part swap --size "$SWAP_MEMORY"
part / --fstype ext4 --size 1024 --grow
EOF

Provisioning templates

A provisioning template defines the way orcharhino Server installs an operating system on a host.

orcharhino includes many template examples. In the orcharhino management UI, navigate to Hosts > Templates > Provisioning Templates to view them. You can create a template or clone a template and edit the clone. For help with templates, navigate to Hosts > Templates > Provisioning Templates > Create Template > Help.

Templates accept the Embedded Ruby (ERB) syntax. For more information, see Template Writing Reference in Managing Hosts.

You can download provisioning templates. Before you can download the template, you must create a debug certificate. For more information, see Creating an Organization Debug Certificate in Managing Organizations and Locations.

You can synchronize templates between orcharhino Server and a Git repository or a local directory. For more information, see Synchronizing Templates Repositories in Managing Hosts.

To view the history of changes applied to a template, navigate to Hosts > Templates > Provisioning Templates, select one of the templates, and click History. Click Revert to override the content with the previous version. You can also revert to an earlier change. Click Show Diff to see information about a specific change:

  • The Template Diff tab displays changes in the body of a provisioning template.

  • The Details tab displays changes in the template description.

  • The History tab displays the user who made a change to the template and date of the change.

Kinds of provisioning templates

There are various kinds of provisioning templates:

Provision

The main template for the provisioning process. For example, a kickstart template.

PXELinux, PXEGrub, PXEGrub2

PXE-based templates that deploy to the template orcharhino Proxy associated with a subnet to ensure that the host uses the installer with the correct kernel options. For BIOS provisioning, select PXELinux template. For UEFI provisioning, select PXEGrub2.

Finish

Post-configuration scripts to execute using an SSH connection when the main provisioning process completes. You can use Finish templates only for image-based provisioning in virtual or cloud environments that do not support user_data. Do not confuse an image with a foreman discovery ISO, which is sometimes called a Foreman discovery image. An image in this context is an install image in a virtualized environment for easy deployment.

When a finish script successfully exits with the return code 0, orcharhino treats the code as a success and the host exits the build mode.

Note that there are a few finish scripts with a build mode that uses a call back HTTP call. These scripts are not used for image-based provisioning, but for post configuration of operating-system installations such as Debian, Ubuntu, and BSD.

user_data

Post-configuration scripts for providers that accept custom data, also known as seed data. You can use the user_data template to provision virtual machines in cloud or virtualised environments only. This template does not require orcharhino to be able to reach the host; the cloud or virtualization platform is responsible for delivering the data to the image.

Ensure that the image that you want to provision has the software to read the data installed and set to start during boot. For example, cloud-init, which expects YAML input, or ignition, which expects JSON input.

cloud_init

Some environments, such as VMWare, either do not support custom data or have their own data format that limits what can be done during customization. In this case, you can configure a cloud-init client with the foreman plug-in, which attempts to download the template directly from orcharhino over HTTP or HTTPS. This technique can be used in any environment, preferably virtualized.

Ensure that you meet the following requirements to use the cloud_init template:

  • Ensure that the image that you want to provision has the software to read the data installed and set to start during boot.

  • A provisioned host is able to reach orcharhino from the IP address that matches the host’s provisioning interface IP.

    Note that cloud-init does not work behind NAT.

Bootdisk

Templates for PXE-less boot methods.

Kernel Execution (kexec)

Kernel execution templates for PXE-less boot methods.

Script

An arbitrary script not used by default but useful for custom tasks.

ZTP

Zero Touch Provisioning templates.

POAP

PowerOn Auto Provisioning templates.

iPXE

Templates for iPXE or gPXE environments to use instead of PXELinux.

Creating provisioning templates

  7. In the Audit Comment field, enter a summary of changes to the provisioning template for auditing purposes.

  8. Click the Type tab and if your template is a snippet, select the Snippet checkbox. A snippet is not a standalone provisioning template, but a part of a provisioning template that can be inserted into other provisioning templates.

  9. From the Type list, select the type of the template. For example, Provisioning template.

  10. Click the Association tab and from the Applicable Operating Systems list, select the names of the operating systems that you want to associate with the provisioning template.

  11. Optionally, click Add combination and select a host group from the Host Group list or an environment from the Environment list to associate provisioning template with the host groups and environments.

  12. Click the Organizations and Locations tabs to add any additional contexts to the template.

  13. Click Submit to save your provisioning template.

Creating custom provisioning snippets

Custom provisioning snippets allow you to execute custom code during host provisioning. You can run code before and/or after the provisioning process.

Prerequisites

  • Depending on your provisioning template, multiple custom snippet hooks exist which you can use to include custom provisioning snippets. Ensure that you check your provisioning template first to verify which custom snippets you can use.

Procedure

  1. In the orcharhino management UI, navigate to Hosts > Templates > Provisioning Templates and click Create Template.

  2. In the Name field, enter a name for your custom provisioning snippet. The name has to start with the name of a provisioning template that supports including custom provisioning snippets:

    • Append ` custom pre` to the name of a provisioning template to run code before provisioning a host.

    • Append ` custom post` to the name of a provisioning template to run code after provisioning a host.

  3. On the Type tab, select Snippet.

  4. Click Submit to create your custom provisioning snippet.

CLI procedure

  1. Before you create a template with the CLI, create a plain text file that contains your custom snippet.

  2. Create the template using hammer:

    # hammer template create \
--file "/path/to/My_Snippet" \
--locations "My_Location" \
--name "My_Template_Name_custom_pre" \
--organizations "_My_Organization" \
--type snippet

Custom provisioning snippet example for Debian

You can use Custom Post snippets to call external APIs from within the provisioning template directly after provisioning a host.

Preseed default custom post Example for Debian/Ubuntu
echo "Calling API to report successful host deployment"

apt-get install -y curl ca-certificates

curl -X POST \
-H "Content-Type: application/json" \
-d '{"name": "<%= @host.name %>", "operating_system": "<%= @host.operatingsystem.name %>", "status": "provisioned",}' \
"https://api.example.com/"

Installing katello-host-tools-tracer Manually

The katello-host-tools package is responsible for the connection between managed hosts and content from orcharhino Server and orcharhino Proxies. It uploads currently used repositories and installed packages to orcharhino. The katello-host-tools-tracer package signals orcharhino if services such as nginx have to be restarted or the managed host itself has to be rebooted after updating packages such as the Linux Kernel.

Procedure

  1. In the orcharhino management UI, navigate to Monitor > Jobs.

  2. Click Run Job.

  3. In the Job category drop down menu, select Commands.

  4. In the Job template drop down menu, select Run Command - SSH Default.

  5. In the Search Query field, filter your managed hosts, for example all hosts running Ubuntu:

    os = Ubuntu

    Alternatively, you can also filter for specific hosts using name = my-host.example.com.

  6. In the Command field, enter the command to install the katello-host-tools-tracer package:

    # apt install -y katello-host-tools-tracer

  7. Click Submit to install the package.

Creating compute profiles

You can use compute profiles to predefine virtual machine hardware details such as CPUs, memory, and storage. A default installation of orcharhino contains three predefined profiles:

  • 1-Small

  • 2-Medium

  • 3-Large

You can apply compute profiles to all supported compute resources:

Procedure

  1. In the orcharhino management UI, navigate to Infrastructure > Compute Profiles and click Create Compute Profile.

  2. In the Name field, enter a name for the profile.

  3. Click Submit. A new window opens with the name of the compute profile.

  4. In the new window, click the name of each compute resource and edit the attributes you want to set for this compute profile.

Setting a default encrypted root password for hosts

If you do not want to set a plain text default root password for the hosts that you provision, you can use a default encrypted password.

The default root password can be inherited by a host group and consequentially by hosts in that group.

If you change the password and reprovision the hosts in the group that inherits the password, the password will be overwritten on the hosts.

Procedure

  1. Generate an encrypted password:

    $ python3 -c 'import crypt,getpass;pw=getpass.getpass(); print(crypt.crypt(pw)) if (pw==getpass.getpass("Confirm: ")) else exit()'

  2. Copy the password for later use.

  3. In the orcharhino management UI, navigate to Administer > Settings.

  4. On the Settings page, select the Provisioning tab.

  5. In the Name column, navigate to Root password, and click Click to edit.

  6. Paste the encrypted password, and click Save.

Using noVNC to access virtual machines

You can use your browser to access the VNC console of VMs created by orcharhino.

orcharhino supports using noVNC on the following virtualization platforms:

  • VMware

  • Libvirt

  • oVirt

Prerequisites

  • You must have a virtual machine created by orcharhino.

  • For existing virtual machines, ensure that the Display type in the Compute Resource settings is VNC.

  • You must import the Katello root CA certificate into your orcharhino Server. Adding a security exception in the browser is not enough for using noVNC. For more information, see Installing the Katello Root CA Certificate in Administering orcharhino.

Procedure

  1. On your orcharhino Server, configure the firewall to allow VNC service on ports 5900 to 5930.

    # firewall-cmd --add-port=5900-5930/tcp
# firewall-cmd --add-port=5900-5930/tcp --permanent

  2. In the orcharhino management UI, navigate to Infrastructure > Compute Resources and select the name of a compute resource.

  3. In the Virtual Machines tab, select the name of your virtual machine. Ensure the machine is powered on and then select Console.

Provisioning Ubuntu 20.04.3+ Through orcharhino Proxies

Perform these steps to provision hosts running Ubuntu 20.04.3+ or Ubuntu 22.04.

Procedure

  1. On your orcharhino Proxy, ensure Smart Proxy HTTP forward is enabled:

    # grep "^:enabled: true$" /etc/foreman-proxy/settings.d/templates.yml

    Note that this is enabled by default.

  2. On your orcharhino Proxy, open the corresponding port for the Smart Proxy service:

    # firewall-cmd --permanent --zone=public --add-port=8000/tcp
# firewall-cmd --reload

  3. On your orcharhino Server, add your orcharhino Proxy to the list of trusted proxies:

    # orcharhino-installer --foreman-trusted-proxies "127.0.0.1" --foreman-trusted-proxies "::1" --foreman-trusted-proxies "Your_orcharhino_Proxy_IP"

  4. Provide the extracted ISO and ISO image itself on each orcharhino Proxy. Perform the procedure to create an installation medium for Ubuntu 22.04 on your orcharhino Proxy.

  5. Navigate to Hosts > Installation Media and create an installation medium. Set the Path to the extracted ISO image on your orcharhino Proxy.

  6. Navigate to Hosts > Operating Systems and assign the installation medium to your operating system entry for Ubuntu 22.04.

  7. Navigate to Configure > Host Groups, select the host group that you use to deploy Ubuntu 22.04 through an orcharhino Proxy, and set the installation medium entry accordingly.
