In step 1, click Download pull secret . Paste the contents into the pull-secret.txt file and save the contents in the kni user's home directory. 2.2. Configuring the public subnet All of the OpenShift Container Platform cluster nodes must be on the public subnet. IBM Cloud(R) Bare Metal (Classic) does not provide a DHCP server on the subnet. Set it up separately on the provisioner node. You must reset the BASH variables defined when preparing the provisioner node. Rebooting the provisioner node after preparing it will delete the BASH variables previously set. Procedure Install dnsmasq : USD sudo dnf install dnsmasq Open the dnsmasq configuration file: USD sudo vi /etc/dnsmasq.conf Add the following configuration to the dnsmasq configuration file: interface=baremetal except-interface=lo bind-dynamic log-dhcp dhcp-range=<ip_addr>,<ip_addr>,<pub_cidr> 1 dhcp-option=baremetal,121,0.0.0.0/0,<pub_gateway>,<prvn_priv_ip>,<prvn_pub_ip> 2 dhcp-hostsfile=/var/lib/dnsmasq/dnsmasq.hostsfile 1 Set the DHCP range. Replace both instances of <ip_addr> with one unused IP address from the public subnet so that the dhcp-range for the baremetal network begins and ends with the same the IP address. Replace <pub_cidr> with the CIDR of the public subnet. 2 Set the DHCP option. Replace <pub_gateway> with the IP address of the gateway for the baremetal network. Replace <prvn_priv_ip> with the IP address of the provisioner node's private IP address on the provisioning network. Replace <prvn_pub_ip> with the IP address of the provisioner node's public IP address on the baremetal network. To retrieve the value for <pub_cidr> , execute: USD ibmcloud sl subnet detail <publicsubnetid> --output JSON | jq .cidr Replace <publicsubnetid> with the ID of the public subnet. To retrieve the value for <pub_gateway> , execute: USD ibmcloud sl subnet detail <publicsubnetid> --output JSON | jq .gateway -r Replace <publicsubnetid> with the ID of the public subnet. To retrieve the value for <prvn_priv_ip> , execute: USD ibmcloud sl hardware detail <id> --output JSON | \ jq .primaryBackendIpAddress -r Replace <id> with the ID of the provisioner node. To retrieve the value for <prvn_pub_ip> , execute: USD ibmcloud sl hardware detail <id> --output JSON | jq .primaryIpAddress -r Replace <id> with the ID of the provisioner node. Obtain the list of hardware for the cluster: USD ibmcloud sl hardware list Obtain the MAC addresses and IP addresses for each node: USD ibmcloud sl hardware detail <id> --output JSON | \ jq '.networkComponents[] | \ "\(.primaryIpAddress) \(.macAddress)"' | grep -v null Replace <id> with the ID of the node. Example output "10.196.130.144 00:e0:ed:6a:ca:b4" "141.125.65.215 00:e0:ed:6a:ca:b5" Make a note of the MAC address and IP address of the public network. Make a separate note of the MAC address of the private network, which you will use later in the install-config.yaml file. Repeat this procedure for each node until you have all the public MAC and IP addresses for the public baremetal network, and the MAC addresses of the private provisioning network. Add the MAC and IP address pair of the public baremetal network for each node into the dnsmasq.hostsfile file: USD sudo vim /var/lib/dnsmasq/dnsmasq.hostsfile Example input 00:e0:ed:6a:ca:b5,141.125.65.215,master-0 <mac>,<ip>,master-1 <mac>,<ip>,master-2 <mac>,<ip>,worker-0 <mac>,<ip>,worker-1 ... Replace <mac>,<ip> with the public MAC address and public IP address of the corresponding node name. Start dnsmasq : USD sudo systemctl start dnsmasq Enable dnsmasq so that it starts when booting the node: USD sudo systemctl enable dnsmasq Verify dnsmasq is running: USD sudo systemctl status dnsmasq Example output ● dnsmasq.service - DNS caching server. Loaded: loaded (/usr/lib/systemd/system/dnsmasq.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2021-10-05 05:04:14 CDT; 49s ago Main PID: 3101 (dnsmasq) Tasks: 1 (limit: 204038) Memory: 732.0K CGroup: /system.slice/dnsmasq.service └─3101 /usr/sbin/dnsmasq -k Open ports 53 and 67 with UDP protocol: USD sudo firewall-cmd --add-port 53/udp --permanent USD sudo firewall-cmd --add-port 67/udp --permanent Add provisioning to the external zone with masquerade: USD sudo firewall-cmd --change-zone=provisioning --zone=external --permanent This step ensures network address translation for IPMI calls to the management subnet. Reload the firewalld configuration: USD sudo firewall-cmd --reload 2.3. Retrieving the OpenShift Container Platform installer Use the stable-4.x version of the installation program and your selected architecture to deploy the generally available stable version of OpenShift Container Platform: USD export VERSION=stable-4.17 USD export RELEASE_ARCH=<architecture> USD export RELEASE_IMAGE=USD(curl -s https://mirror.openshift.com/pub/openshift-v4/USDRELEASE_ARCH/clients/ocp/USDVERSION/release.txt | grep 'Pull From: quay.io' | awk -F ' ' '{print USD3}') 2.4. Extracting the OpenShift Container Platform installer After retrieving the installer, the step is to extract it. Procedure Set the environment variables: USD export cmd=openshift-baremetal-install USD export pullsecret_file=~/pull-secret.txt USD export extract_dir=USD(pwd) Get the oc binary: USD curl -s https://mirror.openshift.com/pub/openshift-v4/clients/ocp/USDVERSION/openshift-client-linux.tar.gz | tar zxvf - oc Extract the installer: USD sudo cp oc /usr/local/bin USD oc adm release extract --registry-config "USD{pullsecret_file}" --command=USDcmd --to "USD{extract_dir}" USD{RELEASE_IMAGE} USD sudo cp openshift-baremetal-install /usr/local/bin 2.5. Configuring the install-config.yaml file The install-config.yaml file requires some additional details. Most of the information is teaching the installer and the resulting cluster enough about the available IBM Cloud(R) Bare Metal (Classic) hardware so that it is able to fully manage it. The material difference between installing on bare metal and installing on IBM Cloud(R) Bare Metal (Classic) is that you must explicitly set the privilege level for IPMI in the BMC section of the install-config.yaml file. Procedure Configure install-config.yaml . Change the appropriate variables to match the environment, including pullSecret and sshKey . apiVersion: v1 baseDomain: <domain> metadata: name: <cluster_name> networking: machineNetwork: - cidr: <public-cidr> networkType: OVNKubernetes compute: - name: worker replicas: 2 controlPlane: name: master replicas: 3 platform: baremetal: {} platform: baremetal: apiVIP: <api_ip> ingressVIP: <wildcard_ip> provisioningNetworkInterface: <NIC1> provisioningNetworkCIDR: <CIDR> hosts: - name: openshift-master-0 role: master bmc: address: ipmi://10.196.130.145?privilegelevel=OPERATOR 1 username: root password: <password> bootMACAddress: 00:e0:ed:6a:ca:b4 2 rootDeviceHints: deviceName: "/dev/sda" - name: openshift-worker-0 role: worker bmc: address: ipmi://<out-of-band-ip>?privilegelevel=OPERATOR 3 username: <user> password: <password> bootMACAddress: <NIC1_mac_address> 4 rootDeviceHints: deviceName: "/dev/sda" pullSecret: '<pull_secret>' sshKey: '<ssh_pub_key>' 1 3 The bmc.address provides a privilegelevel configuration setting with the value set to OPERATOR . This is required for IBM Cloud(R) Bare Metal (Classic) infrastructure. 2 4 Add the MAC address of the private provisioning network NIC for the corresponding node. Note You can use the ibmcloud command-line utility to retrieve the password. USD ibmcloud sl hardware detail <id> --output JSON | \ jq '"(.networkManagementIpAddress) (.remoteManagementAccounts[0].password)"' Replace <id> with the ID of the node. Create a directory to store the cluster configuration: USD mkdir ~/clusterconfigs Copy the install-config.yaml file into the directory: USD cp install-config.yaml ~/clusterconfigs Ensure all bare metal nodes are powered off prior to installing the OpenShift Container Platform cluster: USD ipmitool -I lanplus -U <user> -P <password> -H <management_server_ip> power off Remove old bootstrap resources if any are left over from a deployment attempt: for i in USD(sudo virsh list | tail -n +3 | grep bootstrap | awk {'print USD2'}); do sudo virsh destroy USDi; sudo virsh undefine USDi; sudo virsh vol-delete USDi --pool USDi; sudo virsh vol-delete USDi.ign --pool USDi; sudo virsh pool-destroy USDi; sudo virsh pool-undefine USDi; done 2.6. Additional install-config parameters See the following tables for the required parameters, the hosts parameter, and the bmc parameter for the install-config.yaml file. Table 2.1. Required parameters Parameters Default Description baseDomain The domain name for the cluster. For example, example.com . bootMode UEFI The boot mode for a node. Options are legacy , UEFI , and UEFISecureBoot . If bootMode is not set, Ironic sets it while inspecting the node. bootstrapExternalStaticDNS The static network DNS of the bootstrap node. You must set this value when deploying a cluster with static IP addresses when there is no Dynamic Host Configuration Protocol (DHCP) server on the bare-metal network. If you do not set this value, the installation program will use the value from bootstrapExternalStaticGateway , which causes problems when the IP address values of the gateway and DNS are different. bootstrapExternalStaticIP The static IP address for the bootstrap VM. You must set this value when deploying a cluster with static IP addresses when there is no DHCP server on the bare-metal network. bootstrapExternalStaticGateway The static IP address of the gateway for the bootstrap VM. You must set this value when deploying a cluster with static IP addresses when there is no DHCP server on the bare-metal network. sshKey The sshKey configuration setting contains the key in the ~/.ssh/id_rsa.pub file required to access the control plane nodes and compute nodes. Typically, this key is from the provisioner node. pullSecret The pullSecret configuration setting contains a copy of the pull secret downloaded from the Install OpenShift on Bare Metal page when preparing the provisioner node. The name to be given to the OpenShift Container Platform cluster. For example, openshift . The public CIDR (Classless Inter-Domain Routing) of the external network. For example, 10.0.0.0/24 . The OpenShift Container Platform cluster requires a name be provided for compute nodes even if there are zero nodes. Replicas sets the number of compute nodes in the OpenShift Container Platform cluster. The OpenShift Container Platform cluster requires a name for control plane nodes. Replicas sets the number of control plane nodes included as part of the OpenShift Container Platform cluster. provisioningNetworkInterface The name of the network interface on nodes connected to the provisioning network. For OpenShift Container Platform 4.9 and later releases, use the bootMACAddress configuration setting to enable Ironic to identify the IP address of the NIC instead of using the provisioningNetworkInterface configuration setting to identify the name of the NIC. defaultMachinePlatform The default configuration used for machine pools without a platform configuration. apiVIPs (Optional) The virtual IP address for Kubernetes API communication. This setting must either be provided in the install-config.yaml file as a reserved IP from the MachineNetwork or preconfigured in the DNS so that the default name resolves correctly. Use the virtual IP address and not the FQDN when adding a value to the apiVIPs configuration setting in the install-config.yaml file. The primary IP address must be from the IPv4 network when using dual stack networking. If not set, the installation program uses api.<cluster_name>.<base_domain> to derive the IP address from the DNS. Note Before OpenShift Container Platform 4.12, the cluster installation program only accepted an IPv4 address or an IPv6 address for the apiVIP configuration setting. From OpenShift Container Platform 4.12 or later, the apiVIP configuration setting is deprecated. Instead, use a list format for the apiVIPs configuration setting to specify an IPv4 address, an IPv6 address or both IP address formats. disableCertificateVerification False redfish and redfish-virtualmedia need this parameter to manage BMC addresses. The value should be True when using a self-signed certificate for BMC addresses. ingressVIPs (Optional) The virtual IP address for ingress traffic. This setting must either be provided in the install-config.yaml file as a reserved IP from the MachineNetwork or preconfigured in the DNS so that the default name resolves correctly. Use the virtual IP address and not the FQDN when adding a value to the ingressVIPs configuration setting in the install-config.yaml file. The primary IP address must be from the IPv4 network when using dual stack networking. If not set, the installation program uses test.apps.<cluster_name>.<base_domain> to derive the IP address from the DNS. Note Before OpenShift Container Platform 4.12, the cluster installation program only accepted an IPv4 address or an IPv6 address for the ingressVIP configuration setting. In OpenShift Container Platform 4.12 and later, the ingressVIP configuration setting is deprecated. Instead, use a list format for the ingressVIPs configuration setting to specify an IPv4 addresses, an IPv6 addresses or both IP address formats. Table 2.2. Optional Parameters Parameters Default Description provisioningDHCPRange 172.22.0.10,172.22.0.100 Defines the IP range for nodes on the provisioning network. provisioningNetworkCIDR 172.22.0.0/24 The CIDR for the network to use for provisioning. This option is required when not using the default address range on the provisioning network. clusterProvisioningIP The third IP address of the provisioningNetworkCIDR . The IP address within the cluster where the provisioning services run. Defaults to the third IP address of the provisioning subnet. For example, 172.22.0.3 . bootstrapProvisioningIP The second IP address of the provisioningNetworkCIDR . The IP address on the bootstrap VM where the provisioning services run while the installer is deploying the control plane (master) nodes. Defaults to the second IP address of the provisioning subnet. For example, 172.22.0.2 or 2620:52:0:1307::2 . externalBridge baremetal The name of the bare-metal bridge of the hypervisor attached to the bare-metal network. provisioningBridge provisioning The name of the provisioning bridge on the provisioner host attached to the provisioning network. architecture Defines the host architecture for your cluster. Valid values are amd64 or arm64 . defaultMachinePlatform The default configuration used for machine pools without a platform configuration. bootstrapOSImage A URL to override the default operating system image for the bootstrap node. The URL must contain a SHA-256 hash of the image. For example: https://mirror.openshift.com/rhcos-<version>-qemu.qcow2.gz?sha256=<uncompressed_sha256> . provisioningNetwork The provisioningNetwork configuration setting determines whether the cluster uses the provisioning network. If it does, the configuration setting also determines if the cluster manages the network. Disabled : Set this parameter to Disabled to disable the requirement for a provisioning network. When set to Disabled , you must only use virtual media based provisioning, or bring up the cluster using the assisted installer. If Disabled and using power management, BMCs must be accessible from the bare-metal network. If Disabled , you must provide two IP addresses on the bare-metal network that are used for the provisioning services. Managed : Set this parameter to Managed , which is the default, to fully manage the provisioning network, including DHCP, TFTP, and so on. Unmanaged : Set this parameter to Unmanaged to enable the provisioning network but take care of manual configuration of DHCP. Virtual media provisioning is recommended but PXE is still available if required. httpProxy Set this parameter to the appropriate HTTP proxy used within your environment. httpsProxy Set this parameter to the appropriate HTTPS proxy used within your environment. noProxy Set this parameter to the appropriate list of exclusions for proxy usage within your environment. Hosts The hosts parameter is a list of separate bare metal assets used to build the cluster. Table 2.3. Hosts Name Default Description name The name of the BareMetalHost resource to associate with the details. For example, openshift-master-0 . role The role of the bare metal node. Either master (control plane node) or worker (compute node). bmc Connection details for the baseboard management controller. See the BMC addressing section for additional details. bootMACAddress The MAC address of the NIC that the host uses for the provisioning network. Ironic retrieves the IP address using the bootMACAddress configuration setting. Then, it binds to the host. Note You must provide a valid MAC address from the host if you disabled the provisioning network. networkConfig Set this optional parameter to configure the network interface of a host. See "(Optional) Configuring host network interfaces" for additional details. 2.7. Root device hints The rootDeviceHints parameter enables the installer to provision the Red Hat Enterprise Linux CoreOS (RHCOS) image to a particular device. The installer examines the devices in the order it discovers them, and compares the discovered values with the hint values. The installer uses the first discovered device that matches the hint value. The configuration can combine multiple hints, but a device must match all hints for the installer to select it. Table 2.4. Subfields Subfield Description deviceName A string containing a Linux device name such as /dev/vda or /dev/disk/by-path/ . It is recommended to use the /dev/disk/by-path/<device_path> link to the storage location. The hint must match the actual value exactly. hctl A string containing a SCSI bus address like 0:0:0:0 . The hint must match the actual value exactly. model A string containing a vendor-specific device identifier. The hint can be a substring of the actual value. vendor A string containing the name of the vendor or manufacturer of the device. The hint can be a sub-string of the actual value. serialNumber A string containing the device serial number. The hint must match the actual value exactly. minSizeGigabytes An integer representing the minimum size of the device in gigabytes. wwn A string containing the unique storage identifier. The hint must match the actual value exactly. wwnWithExtension A string containing the unique storage identifier with the vendor extension appended. The hint must match the actual value exactly. wwnVendorExtension A string containing the unique vendor storage identifier. The hint must match the actual value exactly. rotational A boolean indicating whether the device should be a rotating disk (true) or not (false). Example usage - name: master-0 role: master bmc: address: ipmi://10.10.0.3:6203 username: admin password: redhat bootMACAddress: de:ad:be:ef:00:40 rootDeviceHints: deviceName: "/dev/sda" 2.8.
