2.6.7. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

  • Configure an account with the cloud platform that hosts your cluster.
  • Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

  1. Run the installation program:

    $ ./openshift-install create cluster --dir=<installation_directory> \ 1
        --log-level=info 2
    1
    For <installation_directory>, specify the location of your customized ./install-config.yaml file.
    2
    To view different installation details, specify warn, debug, or error instead of info.
    注記

    If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.

    When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.

    重要

    The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.

    重要

    You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

  2. Optional: Remove or disable the AdministratorAccess policy from the IAM account that you used to install the cluster.
