Manually creating the installation configuration file

For installations of {product-title} that use user-provisioned infrastructure, you must manually generate your installation configuration file.

Prerequisites

  • Obtain the {product-title} installation program and the access token for your cluster.

Procedure

  1. Create an installation directory to store your required installation assets in:

    $ mkdir <installation_directory>
    Important

    You must create a directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier {product-title} version.

  2. Customize the following install-config.yaml file template and save it in the <installation_directory>.

    Note

    You must name this configuration file install-config.yaml.

  3. Back up the install-config.yaml file so that you can use it to install multiple clusters.

    Important

    The install-config.yaml file is consumed during the next step of the installation process. You must back it up now.
