第10章 Creating Kickstart files


You can create a Kickstart file by using the following different methods:

  • Use the online Kickstart configuration tool.
  • Copy the Kickstart file created as a result of installation.
  • Write the entire Kickstart file manually.
  • Convert the Red Hat Enterprise Linux 9 Kickstart file for Red Hat Enterprise Linux 10 installation.

    For more information about the conversion tool, see Kickstart generator lab.

  • In case of virtual and cloud environments, create a custom system image by using Image Builder.

Some highly specific installation options can be configured only by manual editing of the Kickstart file.

10.1. Creating a Kickstart file with the Kickstart configuration tool

Use the Red Hat Customer Portal Kickstart Generator to create automated installation files through a web-based interface. The Kickstart generator simplifies the creation of Kickstart files for automated RHEL deployments without requiring manual file editing or syntax knowledge.

Prerequisites

  • You have a Red Hat Customer Portal account and an active Red Hat subscription.

Procedure

  1. Open the Kickstart generator lab.
  2. Click the Go to Application button to the left of the heading and wait for the next page to load.
  3. Select Red Hat Enterprise Linux 10 in the drop-down menu and wait for the page to update.
  4. Describe the system to be installed by using the fields in the form.

    You can use the links on the left side of the form to quickly navigate between sections of the form.

  5. To download the generated Kickstart file, click the red Download button at the top of the page.

    Your web browser saves the file.

  6. Install the pykickstart package.

    # dnf install pykickstart
  7. Run ksvalidator on your Kickstart file.

    $ ksvalidator -v RHEL10 /path/to/kickstart.ks

    Replace /path/to/kickstart.ks with the path to the Kickstart file you want to verify.

    The validation tool cannot guarantee the installation will be successful. It ensures only that the syntax is correct and that the file does not include deprecated options. It does not attempt to validate the %pre, %post and %packages sections of the Kickstart file.
