Creating a cluster with Anthos on bare metal

Creating a cluster with Anthos on bare metal

  • As described in Solution Overview, it is possible to define four types of clusters with Anthos on bare metal - admin cluster, user cluster, hybrid cluster, and stand-alone cluster.

    This section provides the steps to create a hybrid cluster.

    Prerequisites

    1. The bmctl tool is downloaded and installed on the Linux workstation machine.
    1. The Linux workstation that is running the bmctl tool has network connectivity to all the nodes of the target hybrid cluster and the control plane VIP.
    2. The root user has SSH keys or SUDO user access on all nodes in the target hybrid cluster.

    Deployment steps

    To create the hybrid cluster:

    1. SSH to the Linux workstation machine and change to the bare metal directory that you created in Prepare Linux workstation 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 more 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 the checks are successful, the cluster is created.

    The bmctl logs, the preflight check and the node installation logs, are in the baremetal/bmctl-workspace/<CLUSTER_NAME>/log directory:

    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 the cluster.

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