Chapter 11. Deploying installer-provisioned clusters on IBM Cloud
11.1. Prerequisites
You can use installer-provisioned installation to install OpenShift Container Platform on IBM Cloud® nodes. This document describes the prerequisites and procedures when installing OpenShift Container Platform on IBM Cloud nodes.
Red Hat supports IPMI and PXE on the provisioning
network only. Red Hat has not tested Red Fish, virtual media, or other complementary technologies such as Secure Boot on IBM Cloud deployments. The provisioning
network is required.
Installer-provisioned installation of OpenShift Container Platform requires:
- One provisioner node with Red Hat Enterprise Linux CoreOS (RHCOS) 8.x installed
- Three control plane nodes
- One routable network
- One network for provisioning nodes
Before starting an installer-provisioned installation of OpenShift Container Platform on IBM Cloud, address the following prerequisites and requirements.
11.1.1. Setting up IBM Cloud infrastructure
To deploy an OpenShift Container Platform cluster on IBM Cloud®, you must first provision the IBM Cloud nodes.
Red Hat supports IPMI and PXE on the provisioning
network only. Red Hat has not tested Red Fish, virtual media, or other complementary technologies such as Secure Boot on IBM Cloud deployments. The provisioning
network is required.
You can customize IBM Cloud nodes using the IBM Cloud API. When creating IBM Cloud nodes, you must consider the following requirements.
Use one data center per cluster
All nodes in the OpenShift Container Platform cluster must run in the same IBM Cloud data center.
Create public and private VLANs
Create all nodes with a single public VLAN and a single private VLAN.
Ensure subnets have sufficient IP addresses
IBM Cloud public VLAN subnets use a /28
prefix by default, which provides 16 IP addresses. That is sufficient for a cluster consisting of three control plane nodes, four worker nodes, and two IP addresses for the API VIP and Ingress VIP on the baremetal
network. For larger clusters, you might need a smaller prefix.
IBM Cloud private VLAN subnets use a /26
prefix by default, which provides 64 IP addresses. IBM Cloud will use private network IP addresses to access the Baseboard Management Controller (BMC) of each node. OpenShift Container Platform creates an additional subnet for the provisioning
network. Network traffic for the provisioning
network subnet routes through the private VLAN. For larger clusters, you might need a smaller prefix.
IP addresses | Prefix |
---|---|
32 |
|
64 |
|
128 |
|
256 |
|
Configuring NICs
OpenShift Container Platform deploys with two networks:
-
provisioning
: Theprovisioning
network is a non-routable network used for provisioning the underlying operating system on each node that is a part of the OpenShift Container Platform cluster. -
baremetal
: Thebaremetal
network is a routable network. You can use any NIC order to interface with thebaremetal
network, provided it is not the NIC specified in theprovisioningNetworkInterface
configuration setting or the NIC associated to a node’sbootMACAddress
configuration setting for theprovisioning
network.
While the cluster nodes can contain more than two NICs, the installation process only focuses on the first two NICs. For example:
NIC | Network | VLAN |
---|---|---|
NIC1 |
| <provisioning_vlan> |
NIC2 |
| <baremetal_vlan> |
In the previous example, NIC1 on all control plane and worker nodes connects to the non-routable network (provisioning
) that is only used for the installation of the OpenShift Container Platform cluster. NIC2 on all control plane and worker nodes connects to the routable baremetal
network.
PXE | Boot order |
---|---|
NIC1 PXE-enabled | 1 |
NIC2 | 2 |
Ensure PXE is enabled on the NIC used for the provisioning
network and is disabled on all other NICs.
Configuring canonical names
Clients access the OpenShift Container Platform cluster nodes over the baremetal
network. Configure IBM Cloud subdomains or subzones where the canonical name extension is the cluster name.
<cluster_name>.<domain>
For example:
test-cluster.example.com
Creating DNS entries
You must create DNS A
record entries resolving to unused IP addresses on the public subnet for the following:
Usage | Host Name | IP |
---|---|---|
API | api.<cluster_name>.<domain> | <ip> |
Ingress LB (apps) | *.apps.<cluster_name>.<domain> | <ip> |
Control plane and worker nodes already have DNS entries after provisioning.
The following table provides an example of fully qualified domain names. The API and Nameserver addresses begin with canonical name extensions. The host names of the control plane and worker nodes are examples, so you can use any host naming convention you prefer.
Usage | Host Name | IP |
---|---|---|
API | api.<cluster_name>.<domain> | <ip> |
Ingress LB (apps) | *.apps.<cluster_name>.<domain> | <ip> |
Provisioner node | provisioner.<cluster_name>.<domain> | <ip> |
Master-0 | openshift-master-0.<cluster_name>.<domain> | <ip> |
Master-1 | openshift-master-1.<cluster_name>.<domain> | <ip> |
Master-2 | openshift-master-2.<cluster_name>.<domain> | <ip> |
Worker-0 | openshift-worker-0.<cluster_name>.<domain> | <ip> |
Worker-1 | openshift-worker-1.<cluster_name>.<domain> | <ip> |
Worker-n | openshift-worker-n.<cluster_name>.<domain> | <ip> |
OpenShift Container Platform includes functionality that uses cluster membership information to generate A
records. This resolves the node names to their IP addresses. After the nodes are registered with the API, the cluster can disperse node information without using CoreDNS-mDNS. This eliminates the network traffic associated with multicast DNS.
After provisioning the IBM Cloud nodes, you must create a DNS entry for the api.<cluster_name>.<domain>
domain name on the external DNS because removing CoreDNS causes the local entry to disappear. Failure to create a DNS record for the api.<cluster_name>.<domain>
domain name in the external DNS server prevents worker nodes from joining the cluster.
Network Time Protocol (NTP)
Each OpenShift Container Platform node in the cluster must have access to an NTP server. OpenShift Container Platform nodes use NTP to synchronize their clocks. For example, cluster nodes use SSL certificates that require validation, which might fail if the date and time between the nodes are not in sync.
Define a consistent clock date and time format in each cluster node’s BIOS settings, or installation might fail.
Configure a DHCP server
IBM Cloud does not run DHCP on the public or private VLANs. After provisioning IBM Cloud nodes, you must set up a DHCP server for the public VLAN, which corresponds to OpenShift Container Platform’s baremetal
network.
The IP addresses allocated to each node do not need to match the IP addresses allocated by the IBM Cloud provisioning system.
See the "Configuring the public subnet" section for details.
Ensure BMC access privileges
The "Remote management" page for each node on the dashboard contains the node’s intelligent platform management interface (IPMI) credentials. The default IPMI privileges prevent the user from making certain boot target changes. You must change the privilege level to OPERATOR
so that Ironic can make those changes.
In the install-config.yaml
file, add the privilegelevel
parameter to the URLs used to configure each BMC. See the "Configuring the install-config.yaml file" section for additional details. For example:
ipmi://<IP>:<port>?privilegelevel=OPERATOR
Alternatively, contact IBM Cloud support and request that they increase the IPMI privileges to ADMINISTRATOR
for each node.
Create bare metal servers
Create bare metal servers in the IBM Cloud dashboard by navigating to Create resource
Alternatively, you can create bare metal servers with the ibmcloud
CLI utility. For example:
$ ibmcloud sl hardware create --hostname <SERVERNAME> \ --domain <DOMAIN> \ --size <SIZE> \ --os <OS-TYPE> \ --datacenter <DC-NAME> \ --port-speed <SPEED> \ --billing <BILLING>
See Installing the stand-alone IBM Cloud CLI for details on installing the IBM Cloud CLI.
IBM Cloud servers might take 3-5 hours to become available.
11.2. Setting up the environment for an OpenShift Container Platform installation
11.2.1. Preparing the provisioner node for OpenShift Container Platform installation on IBM Cloud
Perform the following steps to prepare the provisioner node.
Procedure
-
Log in to the provisioner node via
ssh
. Create a non-root user (
kni
) and provide that user withsudo
privileges:# useradd kni
# passwd kni
# echo "kni ALL=(root) NOPASSWD:ALL" | tee -a /etc/sudoers.d/kni
# chmod 0440 /etc/sudoers.d/kni
Create an
ssh
key for the new user:# su - kni -c "ssh-keygen -f /home/kni/.ssh/id_rsa -N ''"
Log in as the new user on the provisioner node:
# su - kni
Use Red Hat Subscription Manager to register the provisioner node:
$ sudo subscription-manager register --username=<user> --password=<pass> --auto-attach
$ sudo subscription-manager repos --enable=rhel-8-for-x86_64-appstream-rpms \ --enable=rhel-8-for-x86_64-baseos-rpms
NoteFor more information about Red Hat Subscription Manager, see Using and Configuring Red Hat Subscription Manager.

Create a
pull-secret.txt
file:$ vim pull-secret.txt
In a web browser, navigate to Install on Bare Metal with user-provisioned infrastructure. In step 1, click Download pull secret. Paste the contents into the
pull-secret.txt
file and save the contents in thekni
user’s home directory.
11.2.2. Configuring the public subnet
All of the OpenShift Container Platform cluster nodes must be on the public subnet. IBM Cloud® 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
:$ sudo dnf install dnsmasq
Open the
dnsmasq
configuration file:$ 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 thedhcp-range
for thebaremetal
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 thebaremetal
network. Replace<prvn_priv_ip>
with the IP address of the provisioner node’s private IP address on theprovisioning
network. Replace<prvn_pub_ip>
with the IP address of the provisioner node’s public IP address on thebaremetal
network.
To retrieve the value for
<pub_cidr>
, execute:$ 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>

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 publicbaremetal
network, and the MAC addresses of the privateprovisioning
network.Add the MAC and IP address pair of the public
baremetal
network for each node into thednsmasq.hostsfile

11.2.3. Retrieving the OpenShift Container Platform installer
Use the stable-4.x
version of the installer to deploy the generally available stable version of OpenShift Container Platform:
$ export VERSION=stable-4.9 export RELEASE_IMAGE=$(curl -s https://mirror.openshift.com/pub/openshift-v4/clients/ocp/$VERSION/release.txt | grep 'Pull From: quay.io' | awk -F ' ' '{print $3}')
11.2.4. Extracting the OpenShift Container Platform installer
After retrieving the installer, the next step is to extract it.
Procedure
Set the environment variables:
$ export cmd=openshift-baremetal-install $ export pullsecret_file=~/pull-secret.txt $ export extract_dir=$(pwd)
Get the
oc
binary:$ curl -s https://mirror.openshift.com/pub/openshift-v4/clients/ocp/$VERSION/openshift-client-linux.tar.gz | tar zxvf - oc
Extract the installer:
$ sudo cp oc /usr/local/bin $ oc adm release extract --registry-config "${pullsecret_file}" --command=$cmd --to "${extract_dir}" ${RELEASE_IMAGE} $ sudo cp openshift-baremetal-install /usr/local/bin
11.2.5. 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® hardware so that it is able to fully manage it. The material difference between installing on bare metal and installing on IBM Cloud 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, includingpullSecret
andsshKey
.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>'
NoteYou can use the
ibmcloud
command-line utility to retrieve the password.$ 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:
$ mkdir ~/clusterconfigs
Copy the
install-config.yaml
file into the directory:$ cp install-config.yaml ~/clusterconfig
Ensure all bare metal nodes are powered off prior to installing the OpenShift Container Platform cluster:
$ ipmitool -I lanplus -U <user> -P <password> -H <management_server_ip> power off
Remove old bootstrap resources if any are left over from a previous deployment attempt:
for i in $(sudo virsh list | tail -n +3 | grep bootstrap | awk {'print $2'}); do sudo virsh destroy $i; sudo virsh undefine $i; sudo virsh vol-delete $i --pool $i; sudo virsh vol-delete $i.ign --pool $i; sudo virsh pool-destroy $i; sudo virsh pool-undefine $i; done
