2.5. Configuring the install-config.yaml file

Procedure

1. 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>'

   The bmc.address provides a privilegelevel configuration setting with the value set to OPERATOR. This is required for IBM Cloud® Bare Metal (Classic) infrastructure.

   Add the MAC address of the private provisioning network NIC for the corresponding node.

   참고

   You 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.

2. Create a directory to store the cluster configuration:

   $ mkdir ~/clusterconfigs

3. Copy the install-config.yaml file into the directory:

   $ cp install-config.yaml ~/clusterconfigs

4. 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

5. 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
