Add a bare metal host using CLI

Add a bare metal host using CLI

This section describes how to add bare metal hosts using the Container Cloud CLI during a managed cluster creation.

To add a bare metal host using API:

  1. Verify that you configured each bare metal host as follows:

    • Enable the boot NIC support for UEFI load. Usually, at least the built-in network interfaces support it.

    • Enable the UEFI-LAN-OPROM support in BIOS -> Advanced -> PCIPCIe.

    • Enable the IPv4-PXE stack.

    • Set the following boot order:

      1. UEFI-DISK

      2. UEFI-PXE

    • If your PXE network is not configured to use the first network interface, fix the UEFI-PXE boot order to speed up node discovering by selecting only one required network interface.

    • Power off all bare metal hosts.

    Warning

    Only one Ethernet port on a host must be connected to the Common/PXE network at any given time. The physical address (MAC) of this interface must be noted and used to configure the BareMetalHost object describing the host.

  2. Optional. Create a custom bare metal host profile depending on your needs as described in Create a custom bare metal host profile.

  3. Log in to the host where your management cluster kubeconfig is located and where kubectl is installed.

  4. Create a secret YAML file that describes the unique credentials of the new bare metal host.

    Example of the bare metal host secret:

    apiVersion: v1
    data:
      password: <credentials-password>
      username: <credentials-user-name>
    kind: Secret
    metadata:
      labels:
        kaas.mirantis.com/credentials: "true"
        kaas.mirantis.com/provider: baremetal
        kaas.mirantis.com/region: region-one
      name: <credentials-name>
      namespace: <managed-cluster-project-name>
    type: Opaque
    

    In the data section, add the IPMI user name and password in the base64 encoding to access the BMC. To obtain the base64-encoded credentials, you can use the following command in your Linux console:

    echo -n <username|password> | base64
    

    Caution

    Each bare metal host must have a unique Secret.

  5. Apply this secret YAML file to your deployment:

    kubectl apply -f ${<bmh-cred-file-name>}.yaml
    
  6. Create a YAML file that contains a description of the new bare metal host.

    Example of the bare metal host configuration file with the worker role:

    apiVersion: metal3.io/v1alpha1
    kind: BareMetalHost
    metadata:
      labels:
        kaas.mirantis.com/baremetalhost-id: <unique-bare-metal-host-hardware-node-id>
        hostlabel.bm.kaas.mirantis.com/worker: "true"
        kaas.mirantis.com/provider: baremetal
        kaas.mirantis.com/region: region-one
      name: <bare-metal-host-unique-name>
      namespace: <managed-cluster-project-name>
    spec:
      bmc:
        address: <ip_address_for-bmc-access>
        credentialsName: <credentials-name>
      bootMACAddress: <bare-metal-host-boot-mac-address>
      online: true
    

    For a detailed fields description, see BareMetalHost.

  7. Apply this configuration YAML file to your deployment:

    kubectl apply -f ${<bare-metal-host-config-file-name>}.yaml
    

Now, proceed with Create a managed cluster.
