Deploying and Installing SUSE AI|Installing the Linux and Kubernetes distribution
Applies to SUSE AI 1.0

2 Installing the Linux and Kubernetes distribution

 

This procedure includes the steps to install the base Linux operating system and a Kubernetes distribution for users who start deploying on cluster nodes from scratch. If you already have Kubernetes cluster(s) installed and running, you can skip this procedure and continue with Section 4.1, “Installation procedure”.

  1. Install and register a supported Linux operating system on each cluster node. We recommend using one of the following operating systems:

  2. Install the NVIDIA GPU driver on cluster nodes with GPUs. Refer to Section 2.2, “Installing NVIDIA GPU drivers” for details.

  3. Install Kubernetes on cluster nodes.

    Important
    Important: Separate clusters for specific SUSE AI components

    For production deployments, we strongly recommended deploying Rancher, SUSE Observability, and workloads from the AI library to separate Kubernetes clusters.

    We recommend using the supported SUSE Rancher Prime: RKE2 distribution. Refer to Section 2.3, “Installing SUSE Rancher Prime: RKE2” for details. For a list of supported Kubernetes platforms, refer to https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/.

2.1 Installing SUSE Linux Enterprise Server

 

Use the following procedures to install SLES on all supported hardware platforms. They assume you have successfully booted into the installation system. For more detailed installation instructions and deployment strategies, refer to SUSE Linux Enterprise Server Deployment Guide.

2.1.1 The Unified Installer

 

Starting with SLES 15, the installation medium consists only of the Unified Installer, a minimal system for installing, updating and registering all SLE base products. During the installation, you can add functionality by selecting modules and extensions to be installed on top of the Unified Installer.

2.1.2 Installing offline or without registration

 

The default installation medium 15 SP6-Online-ARCH-GM-media1.iso is optimized for size and does not contain any modules and extensions. Therefore, the installation requires network access to register your product and retrieve repository data for the modules and extensions.

For installation without registering the system, use the 15 SP6-Full-ARCH-GM-media1.iso image from https://www.suse.com/download/sles/ and refer to Installing without registration.

Tip
Tip: Copying the installation media image to a removable flash disk

Use the following command to copy the contents of the installation image to a removable flash disk.

> sudo dd if=IMAGE of=FLASH_DISK bs=4M && sync

IMAGE needs to be replaced with the path to the 15 SP6-Online-ARCH-GM-media1.iso or 15 SP6-Full-ARCH-GM-media1.iso image file. FLASH_DISK needs to be replaced with the flash device. To identify the device, insert it and run:

# grep -Ff <(hwinfo --disk --short) <(hwinfo --usb --short)
disk:
  /dev/sdc             General USB Flash Disk

Make sure the size of the device is sufficient for the desired image. You can check the size of the device with:

# fdisk -l /dev/sdc | grep -e "^/dev"
     /dev/sdc1  *     2048 31490047 31488000  15G 83 Linux

In this example, the device has a capacity of 15 GB. The command to use for the 15 SP6-Full-ARCH-GM-media1.iso would be:

dd if=15 SP6-Full-ARCH-GM-media1.iso of=/dev/sdc bs=4M && sync

The device must not be mounted when running the dd command. Note that all data on the partition will be erased.

2.1.3 The installation procedure

 

To install SLES, boot or IPL into the installer from the Unified Installer medium and start the installation.

2.1.3.1 Language, keyboard and product selection

 
Language, keyboard and product selection screen
Figure 2.1: Language, keyboard and product selection
 

The Language and Keyboard Layout settings are initialized with the language you chose on the boot screen. If you do not change the default, it remains English (US). Change the settings here, if necessary. Use the Keyboard Test text box to test the layout.

Select SUSE Linux Enterprise Server 15 SP6 for installation. You need to have a registration code for the product. Proceed with Next.

Tip
Tip: Light and high-contrast themes

If you have difficulty reading the labels in the installer, you can change the widget colors and theme.

Click the Change the widget theme button or press Shift–F3 to open a theme selection dialog. Select a theme from the list and Close the dialog.

Shift–F4 switches to the color scheme for vision-impaired users. Press the buttons again to switch back to the default scheme.

2.1.3.2 License agreement

 
SLES License Agreement screen
Figure 2.2: License agreement
 

Read the License Agreement. It is presented in the language you have chosen on the boot screen. Translations are available via the License Language drop-down list. You need to accept the agreement by checking I Agree to the License Terms to install SLES. Proceed with Next.

2.1.3.3 Network settings

 
Network Settings screen
Figure 2.3: Network settings
 

A system analysis is performed, where the installer probes for storage devices and tries to find other installed systems. If the network was automatically configured via DHCP during the start of the installation, you are presented the registration step.

If the network is not yet configured, the Network Settings dialog opens. Choose a network interface from the list and configure it with Edit. Alternatively, Add an interface manually. See the sections on installer network settings and configuring a network connection with YaST for more information. If you prefer to do an installation without network access, skip this step without making any changes and proceed with Next.

2.1.3.4 Registration

 
Registration screen
Figure 2.4: Registration
 

To get technical support and product updates, you need to register and activate SLES with the SUSE Customer Center or a local registration server. Registering your product at this stage also grants you immediate access to the update repository. This enables you to install the system with the latest updates and patches available.

When registering, repositories and dependencies for modules and extensions are loaded from the registration server.

Register system at scc.suse.com

To register at the SUSE Customer Center, enter the E-mail Address associated with your SUSE Customer Center account and the Registration Code for SLES. Proceed with Next.

Register system via local RMT server

If your organization provides a local registration server, you may alternatively register to it. Activate Register System via local RMT Server and either choose a URL from the drop-down list or type in an address. Proceed with Next.

Skip registration

If you are offline or want to skip registration, activate Skip Registration. Accept the warning with OK and proceed with Next.

Important
Important: Skipping the registration

Your system and extensions need to be registered to retrieve updates and to be eligible for support. Skipping the registration is only possible when installing from the 15 SP6-Full-ARCH-GM-media1.iso image.

If you do not register during the installation, you can do so at any time later from the running system. To do so, run YaST › Product Registration or the command-line tool SUSEConnect.

Tip
Tip: Installing product patches at installation time

After SLES has been successfully registered, you are asked whether to install the latest available online updates during the installation. If choosing Yes, the system will be installed with the most current packages without having to apply the updates after installation. Activating this option is recommended.

Note
Note: Firewall settings for receiving updates

By default, the firewall on SUSE AI only blocks incoming connections. If your system is behind another firewall that blocks outgoing traffic, make sure to allow connections to https://scc.suse.com/ and https://updates.suse.com on ports 80 and 443 to receive updates.

2.1.3.5 Extension and module selection

 
Extension and Module Selection screen
Figure 2.5: Extension and module selection
 

After the system is successfully registered, the installer lists modules and extensions that are available for SLES. Modules are components that allow you to customize the product according to your needs. They are included in your SLES subscription. Extensions add functionality to your product. They must be purchased separately.

The availability of certain modules or extensions depends on the product selected in the first step of the installation. For a description of the modules and their lifecycles, select a module to see the accompanying text. More detailed information is available in the Modules and extensins quick start guide.

The selection of modules indirectly affects the scope of the installation, because it defines which software sources (repositories) are available for installation and in the running system.

The following modules and extensions are available for SUSE Linux Enterprise Server:

Basesystem Module

This module adds a basic system on top of the Unified Installer. It is required by all other modules and extensions.

If you have chosen an add-on product requiring a registration key, you will be asked to enter it before proceeding to the next step.

2.1.3.7 System role

 
System Role screen
Figure 2.7: System role
 

The availability of system roles depends on your selection of modules and extensions. System roles define, for example, the set of software patterns that are preselected for the installation. Refer to the description on the screen to make your choice. Select a role and proceed with Next. If from the enabled modules only one role or no role is suitable for the respective base product, the System Role dialog is omitted.

Tip
Tip: Release notes

From this point on, the Release Notes can be viewed from any screen during the installation process by selecting Release Notes.

2.1.3.8 Suggested partitioning

 
Suggested Partitioning screen
Figure 2.8: Suggested partitioning
 

Review the partition setup proposed by the system. If necessary, change it. You have the following options:

Guided setup

Starts a wizard that lets you refine the partitioning proposal. The options available here depend on your system setup. If it contains more than a single hard disk, you can choose which disk or disks to use and where to place the root partition. If the disks already contain partitions, decide whether to remove or resize them.

In subsequent steps, you may also add LVM support and disk encryption. You can change the file system for the root partition and decide whether or not to have a separate home partition.

Expert partitioner

Opens the Expert Partitioner. This gives you full control over the partitioning setup and lets you create a custom setup. This option is intended for experts. For details, see the Expert Partitioner chapter.

Warning
Warning: Disk space units

For partitioning purposes, disk space is measured in binary units rather than in decimal units. For example, if you enter sizes of 1GB, 1GiB or 1G, they all signify 1 GiB (Gibibyte), as opposed to 1 GB (Gigabyte).

Binary

1 GiB = 1,073,741,824 bytes.

Decimal

1 GB = 1,000,000,000 bytes.

Difference

1 GiB ≈ 1.07 GB.

To accept the proposed setup without any changes, choose Next to proceed.

2.1.3.9 Clock and time zone

 
Clock and Time Zone screen
Figure 2.9: Clock and time zone
 

Select the clock and time zone to use in your system. To manually adjust the time or to configure an NTP server for time synchronization, choose Other Settings. See the section on Clock and Time Zone for detailed information. Proceed with Next.

2.1.3.10 Local user

 
Local User screen
Figure 2.10: Local user creation
 

To create a local user, type the first and last name in the User’s Full Name field, the login name in the Username field, and the password in the Password field.

The password should be at least eight characters long and should contain both uppercase and lowercase letters and numbers. The maximum length for passwords is 72 characters, and passwords are case-sensitive.

For security reasons, it is also strongly recommended not to enable Automatic Login. You should also not Use this Password for the System Administrator but provide a separate root password in the next installation step.

If you install on a system where a previous Linux installation was found, you may Import User Data from a Previous Installation. Click Choose User for a list of available user accounts. Select one or more users.

In an environment where users are centrally managed (for example, by NIS or LDAP), you can skip the creation of local users. Select Skip User Creation in this case.

Proceed with Next.

2.1.3.11 Authentication for the system administrator root

 
Authentication for the system administrator 'root' screen
Figure 2.11: Password for the system administrator root
 

Type a password for the system administrator (called the root user) or provide a public SSH key. If you want, you can use both.

Because the root user is equipped with extensive permissions, the password should be chosen carefully. You should never forget the root password. After you entered it here, the password cannot be retrieved.

Tip
Tip: Passwords and keyboard layout

It is recommended to use only US ASCII characters. In the event of a system error or when you need to start your system in rescue mode, the keyboard may not be localized.

To access the system remotely via SSH using a public key, import a key from removable media or an existing partition. See the section on Authentication for the system administrator root for more information.

Proceed with Next.

2.1.3.12 Installation settings

Use the Installation Settings screen to review and—if necessary—change several proposed installation settings. The current configuration is listed for each setting. To change it, click the headline. Certain settings, such as firewall or SSH, can be changed directly by clicking the respective links.

Important
Important: Remote access

Changes you can make here can also be made later at any time from the installed system. However, if you need remote access right after the installation, you may need to open the SSH port in the Security settings.

Software

The scope of the installation is defined by the modules and extensions you have chosen for this installation. However, depending on your selection, not all packages available in a module are selected for installation.

Clicking Software opens the Software Selection and System Tasks screen, where you can change the software selection by selecting or deselecting patterns. Each pattern contains several software packages needed for specific functions (for example, KVM Host Server). For a more detailed selection based on software packages to install, select Details to switch to the YaST Software Manager. See Installing or removing software for more information.

Booting

This section shows the boot loader configuration. Changing the defaults is recommended only if really needed. Refer to The boot loader GRUB 2 for details.

Security

By default, the Firewall is enabled on all configured network interfaces. To disable firewalld, click disable (not recommended). Refer to the Masquerading and Firewalls chapter for configuration details.

Note
Note: Firewall settings for receiving updates

By default, the firewall on SUSE AI only blocks incoming connections. If your system is behind another firewall that blocks outgoing traffic, make sure to allow connections to https://scc.suse.com/ and https://updates.suse.com on ports 80 and 443 to receive updates.

The SSH service is enabled by default, but its port (22) is closed in the firewall. Click open to open the port or disable to disable the service. If SSH is disabled, remote logins will not be possible. Refer to Securing network operations with OpenSSH for more information.

The default Major Linux Security Module is AppArmor. To disable it, select None as the module in the Security settings.

Security Policies

Click to enable the Defense Information Systems Agency STIG security policy. If any installation settings are incompatible with the policy, you will be prompted to modify them accordingly. Certain settings can be adjusted automatically while others require user input.

Enabling a security profile enables a full SCAP remediation on first boot. You can also perform a scan only or do nothing and manually remediate the system later with OpenSCAP. For more information, refer to the section on Security Profiles.

Network configuration

Displays the current network configuration. By default, wicked is used for server installations and NetworkManager for desktop workloads. Click Network Configuration to change the settings. For details, see the section on Configuring a network connection with YaST.

Important
Important: Support for NetworkManager

SUSE only supports NetworkManager for desktop workloads with SLED or the Workstation extension. All server certifications are done with wicked as the network configuration tool, and using NetworkManager may invalidate them. NetworkManager is not supported by SUSE for server workloads.

Kdump

Kdump saves the memory image ("core dump") to the file system in case the kernel crashes. This enables you to find the cause of the crash by debugging the dump file. Kdump is preconfigured and enabled by default. See the Basic Kdump configuration for more information.

Default systemd target

If you have installed the desktop applications module, the system boots into the graphical target, with network, multi-user and display manager support. Switch to multi-user if you do not need to log in via a display manager.

2.2 Installing NVIDIA GPU drivers

 

This article demonstrates how to implement host-level NVIDIA GPU support via the open-driver. The `open-driver`is part of the core package repositories. Therefore, there is no need to compile it or download executable packages. This driver is built into the operating system rather than dynamically loaded by the NVIDIA GPU Operator. This configuration is desirable for customers who want to pre-build all artifacts required for deployment into the image, and where the dynamic selection of the driver version via Kubernetes is not a requirement.

2.2.1 Installing NVIDIA GPU drivers on SUSE Linux Enterprise Server

 

2.2.1.1 Requirements

 

If you are following this guide, it assumes that you have the following already available:

  • At least one host with SLES 15 SP6 installed, physical or virtual.

  • Your hosts are attached to a subscription as this is required for package access.

  • A compatible NVIDIA GPU installed or fully passed through to the virtual machine in which SLES is running.

  • Access to the root user—these instructions assume you are the root user, and not escalating your privileges via sudo.

2.2.1.2 Considerations before the installation

 
2.2.1.2.1 Select the driver generation
 

You must verify the driver generation for the NVIDIA GPU that your system has. For modern GPUs, the G06 driver is the most common choice. Find more details in the support database.

This section details the installation of the G06 generation of the driver.

2.2.1.2.2 Additional NVIDIA components
 

Besides the NVIDIA open-driver provided by SUSE as part of SLES, you might also need additional NVIDIA components. These could include OpenGL libraries, CUDA toolkits, command-line utilities such as nvidia-smi, and container-integration components such as nvidia-container-toolkit. Many of these components are not shipped by SUSE as they are proprietary NVIDIA software. This section describes how to configure additional repositories that give you access to these components and provides examples of using these tools to achieve a fully functional system.

2.2.1.3 The installation procedure

 

  1. Add a package repository from NVIDIA. This allows pulling in additional utilities, for example, nvidia-smi.

    For the AMD64/Intel 64 architecture, run:

    # zypper ar \
  https://developer.download.nvidia.com/compute/cuda/repos/sles15/x86_64/ \
  cuda-sle15
# zypper --gpg-auto-import-keys refresh

    For the Arm AArch64 architecture, run:

    # zypper ar \
  https://developer.download.nvidia.com/compute/cuda/repos/sles15/sbsa/ \
  cuda-sle15
transactional update # zypper --gpg-auto-import-keys refresh

  2. Install the Open Kernel driver KMP and detect the driver version.

    # zypper install -y --auto-agree-with-licenses \
  nv-prefer-signed-open-driver
# version=$(rpm -qa --queryformat '%{VERSION}\n' \
  nv-prefer-signed-open-driver | cut -d "_" -f1 | sort -u | tail -n 1)

  3. Install the nvidia-gl-G06 package along with the open driver on the GPU nodes if the application needs NVIDIA Vulkan capabilities.

    # zypper install -y --auto-agree-with-licenses \
nvidia-gl-G06=${version}

  4. You can then install the appropriate packages for additional utilities that are useful for testing purposes.

    # zypper install -y --auto-agree-with-licenses \
nvidia-compute-utils-G06=${version} \
nvidia-persistenced=${version}

  5. Reboot the host to make the changes effective.

    # reboot

  6. Log back in and run nvidia-smi command as root to ensure it correctly detects the GPU and displays the GPU details.

    # nvidia-smi

    The output of this command should show you something similar to the following output. In the example below, the system has one GPU.

2.2.2 Installing NVIDIA GPU drivers on SUSE Linux Enterprise Micro

 

2.2.2.1 Requirements

 

If you are following this guide, it assumes that you have the following already available:

  • At least one host with SUSE Linux Enterprise Micro 6.1 installed, physical or virtual.

  • Your hosts are attached to a subscription as this is required for package access.

  • A compatible NVIDIA GPU installed or fully passed through to the virtual machine in which SUSE Linux Enterprise Micro is running.

  • Access to the root user—these instructions assume you are the root user, and not escalating your privileges via sudo.

2.2.2.2 Considerations before the installation

 
2.2.2.2.1 Select the driver generation
 

You must verify the driver generation for the NVIDIA GPU that your system has. For modern GPUs, the G06 driver is the most common choice. Find more details in the support database.

This section details the installation of the G06 generation of the driver.

2.2.2.2.2 Additional NVIDIA components
 

Besides the NVIDIA open-driver provided by SUSE as part of SUSE Linux Enterprise Micro, you might also need additional NVIDIA components. These could include OpenGL libraries, CUDA toolkits, command-line utilities such as nvidia-smi, and container-integration components such as nvidia-container-toolkit. Many of these components are not shipped by SUSE as they are proprietary NVIDIA software. This section describes how to configure additional repositories that give you access to these components and provides examples of using these tools to achieve a fully functional system.

2.2.2.3 The installation procedure

 

  1. On each (local) GPU-enabled host, open up a transactional-update shell session to create a new read/write snapshot of the underlying operating system so that we can make changes to the immutable platform.

    # transactional-update shell

  2. When you are in the transactional-update shell session, add a package repository from NVIDIA. This allows pulling in additional utilities, for example, nvidia-smi.

    For the AMD64/Intel 64 architecture, run:

    transactional update # zypper ar \
  https://developer.download.nvidia.com/compute/cuda/repos/sles15/x86_64/ \
  cuda-sle15
transactional update # zypper --gpg-auto-import-keys refresh

    For the Arm AArch64 architecture, run:

    transactional update # zypper ar \
  https://developer.download.nvidia.com/compute/cuda/repos/sles15/sbsa/ \
  cuda-sle15
transactional update # zypper --gpg-auto-import-keys refresh

  3. Install the Open Kernel driver KMP and detect the driver version.

    transactional update # zypper install -y --auto-agree-with-licenses \
  nvidia-open-driver-G06-signed-cuda-kmp-default
transactional update # version=$(rpm -qa --queryformat '%{VERSION}\n' \
  nvidia-open-driver-G06-signed-cuda-kmp-default \
  | cut -d "_" -f1 | sort -u | tail -n 1)

  4. Install the nvidia-gl-G06 package along with the open driver on the GPU nodes if the application needs NVIDIA Vulkan capabilities.

    transactional update # zypper install -y --auto-agree-with-licenses \
nvidia-gl-G06=${version}

  5. You can then install the appropriate packages for additional utilities that are useful for testing purposes.

    transactional update # zypper install -y --auto-agree-with-licenses \
nvidia-compute-utils-G06=${version} \
nvidia-persistenced=${version}

  6. Exit the transactional-update session and reboot to the new snapshot that contains the changes you have made.

    transactional update # exit
# reboot

  7. After the system has rebooted, log back in and run nvidia-smi command as root to ensure it correctly detects the GPU and displays the GPU details.

    # nvidia-smi

    The output of this command should show you something similar to the following output. In the example below, the system has one GPU.

2.3 Installing SUSE Rancher Prime: RKE2

 

This guide will help you quickly launch a cluster with default options.

New to Kubernetes? The official Kubernetes docs already have some great tutorials outlining the basics here.

Important
Important

You can use any RKE2 Prime version listed on the Prime Artifacts URL for the assets mentioned in these steps. To learn more about the Prime Artifacts URL, see our Prime-only documentation. Authentication is required. Use your SUSE Customer Center (SCC) credentials to log in.

2.3.1 Prerequisites

 

  • Make sure your environment fulfills the requirements. If NetworkManager is installed and enabled on your hosts, ensure that it is configured to ignore CNI-managed interfaces.

  • If the host kernel supports AppArmor, the AppArmor tools (usually available via the apparmor-parser package) must also be present prior to installing RKE2.

  • The SUSE Rancher Prime: RKE2 installation process must be run as the root user or through sudo.

2.3.2 Server Node Installation

 

SUSE Rancher Prime: RKE2 provides an installation script that is a convenient way to install it as a service on systemd based systems. This script is available at https://get.rke2.io. To install SUSE Rancher Prime: RKE2 using this method do the following:

  1. Run the installer, where INSTALL_RKE2_ARTIFACT_URL is the Prime Artifacts URL and INSTALL_RKE2_CHANNEL is a release channel you can subscribe to and defaults to stable. In this example, INSTALL_RKE2_CHANNEL="latest" gives you the latest version of RKE2.

    curl -sfL https://get.rke2.io/ | sudo INSTALL_RKE2_ARTIFACT_URL=<PRIME-ARTIFACTS-URL>/rke2 INSTALL_RKE2_CHANNEL="latest" sh -

    If you want to specify a version, set the INSTALL_RKE2_VERSION environment variable.

    curl -sfL https://get.rke2.io/ | sudo INSTALL_RKE2_ARTIFACT_URL=<PRIME-ARTIFACTS-URL>/rke2 INSTALL_RKE2_VERSION="<VERSION>" sh -

    This will install the rke2-server service and the rke2 binary onto your machine. Due to its nature, it will fail unless it runs as the root user or through sudo.

  2. Enable the rke2-server service.

    systemctl enable rke2-server.service

  3. To pull images from the Rancher Prime registry, set the following value in etc/rancher/rke2/config.yaml:

    system-default-registry: registry.rancher.com

    This configuration tells RKE2 to use registry.rancher.com as the default location for all container images it needs to deploy within the cluster.

  4. Start the service.

    systemctl start rke2-server.service

  5. Follow the logs with the following command:

    journalctl -u rke2-server -f

After running this installation:

  • The rke2-server service will be installed. The rke2-server service will be configured to automatically restart after node reboots or if the process crashes or is killed.

  • Additional utilities will be installed at /var/lib/rancher/rke2/bin/. They include: kubectl, crictl, and ctr. Note that these are not on your path by default.

  • Two cleanup scripts, rke2-killall.sh and rke2-uninstall.sh, will be installed to the path at:

    • /usr/local/bin for regular file systems

    • /opt/rke2/bin for read-only and brtfs file systems

    • INSTALL_RKE2_TAR_PREFIX/bin if INSTALL_RKE2_TAR_PREFIX is set

  • A kubeconfig file will be written to /etc/rancher/rke2/rke2.yaml.

  • A token that can be used to register other server or agent nodes will be created at /var/lib/rancher/rke2/server/node-token.

Note
Note

If you are adding additional server nodes, you must have an odd number in total. An odd number is needed to maintain quorum. See the High Availability documentation for more details.

2.3.3 Linux Agent (Worker) Node Installation

 

The steps on this section requires root level access or sudo to work.

  1. Run the installer.

    curl -sfL https://get.rke2.io | INSTALL_RKE2_ARTIFACT_URL=<PRIME-ARTIFACTS-URL>/rke2 INSTALL_RKE2_CHANNEL="latest" INSTALL_RKE2_TYPE="agent" sh -

    If you want to specify a version, set the INSTALL_RKE2_VERSION environment variable.

    curl -sfL https://get.rke2.io/ | sudo INSTALL_RKE2_ARTIFACT_URL=<PRIME-ARTIFACTS-URL>/rke2 INSTALL_RKE2_VERSION="<VERSION>" INSTALL_RKE2_TYPE="agent" sh -

    This will install the rke2-agent service and the rke2 binary onto your machine. Due to its nature, it will fail unless it runs as the root user or through sudo.

  2. Enable the rke2-agent service.

    systemctl enable rke2-agent.service

  3. Configure the rke2-agent service.

    mkdir -p /etc/rancher/rke2/
vim /etc/rancher/rke2/config.yaml

    Content for config.yaml:

    server: https://<server>:9345
token: <token from server node>
    Note
    Note

    The rke2 server process listens on port 9345 for new nodes to register. The Kubernetes API is still served on port 6443, as normal.

  4. Start the service.

    systemctl start rke2-agent.service

  5. Follow the logs with the following command:

    journalctl -u rke2-agent -f
Note
Note

Each machine must have a unique host name. If your machines do not have unique host names, set the node-name parameter in the config.yaml file and provide a value with a valid and unique host name for each node. To learn more about the config.yaml file, refer to the Configuration Options documentation.

2.3.4 Windows Agent (Worker) Node Installation

 

Windows Support works with Calico or Flannel as the CNI for the RKE2 cluster.

  1. Prepare the Windows Agent Node.

    Note
    Note

    The Windows Server Containers feature needs to be enabled for the RKE2 agent to work.

    1. Open a new Powershell window with Administrator privileges.

      powershell -Command "Start-Process PowerShell -Verb RunAs"

    2. In the new Powershell window, run the following command to install the containers feature.

      Enable-WindowsOptionalFeature -Online -FeatureName containers –All

      This will require a reboot for the Containers feature to properly function.

  2. Download the install script.

    Invoke-WebRequest -Uri https://raw.githubusercontent.com/rancher/rke2/master/install.ps1 -Outfile install.ps1

    This script will download the rke2.exe Windows binary onto your machine.

  3. Configure the rke2-agent for Windows.

    New-Item -Type Directory c:/etc/rancher/rke2 -Force
Set-Content -Path c:/etc/rancher/rke2/config.yaml -Value @"
server: https://<server>:9345
token: <token from server node>
"@

    To learn more about the config.yaml file, refer to the Configuration Options documentation.

  4. Configure the PATH.

    $env:PATH+=";c:\var\lib\rancher\rke2\bin;c:\usr\local\bin"

[Environment]::SetEnvironmentVariable(
    "Path",
    [Environment]::GetEnvironmentVariable("Path", [EnvironmentVariableTarget]::Machine) + ";c:\var\lib\rancher\rke2\bin;c:\usr\local\bin",
    [EnvironmentVariableTarget]::Machine)

  5. Run the installer.

    ./install.ps1

  6. Start the Windows RKE2 Service.

    rke2.exe agent service --add
Note
Note

Each machine must have a unique host name.

Don’t forget to start the RKE2 service with:

Start-Service rke2

If you would prefer to use CLI parameters only instead, run the binary with the desired parameters.

rke2.exe agent --token <TOKEN> --server <SERVER_URL>
