Creating cluster with Anthos on bare metal

  • As mentioned in Solution Overview section, we can define four types of cluster with Anthos on bare metal - admin cluster, user cluster, hybrid cluster, and stand-alone cluster.

    This section provides instructions to create a hybrid cluster.

    Prerequisites

    1. Download and install bmctl tool on the Linux administration machine.
    1. The Linux administration machine running bmctl tool should have network connectivity to all the nodes of the target hybrid cluster as well as the control plane VIP.
    2. Root user SSH keys or SUDO user access on all nodes in the target hybrid cluster.

    Deployment

    To create the hybrid cluster, complete the following steps:

    1. SSH to the Linux administration machine and change to the bare metal directory created in Prepare Linux administration machine.
    1. Log in to gcloud as a user.

    gcloud auth application-default login
    1. Create the cluster configuration file.

    bmctl create config -c <HYBRID_CLUSTER_NAME>
    1. Modify the configuration file parameters to match your environment-specific variable. For detailed information, see Edit the cluster config file.
    2. Create the cluster.

    ./bmctl create cluster -c CLUSTER_NAME

    The bmctl command runs preflight checks on the cluster config file before it creates a cluster. If they are successful, the cluster is created. The bmctl logs, as well as the preflight check and node installation logs, are in the directory: baremetal/bmctl-workspace/<CLUSTER_NAME>/log.

    1. During cluster creation, the bmctl command writes a kubeconfig file which is written to bmctl-workspace/<CLUSTER_NAME>/<CLUSTER_NAME>-kubeconfig. Verify the successful creation of cluster.

    kubectl --kubeconfig bmctl-workspace/<CLUSTER_NAME>/<CLUSTER_NAME>-kubeconfig get nodes
