Red Hat build of MicroShift

Create a Kickstart file to install MicroShift on image mode for RHEL

You can use the Kickstart file provided with MicroShift for an image mode for RHEL installation.

Prerequisites

You set up the MicroShift Kickstart file.
You have the information needed to set required and optional variables.

Procedure

Set the required BOOTC_IMAGE_URL variable value to point to an image used in the RHEL Kickstart file installation process by running the following command:
```
$ export BOOTC_IMAGE_URL=<myregistry>/<myorg>/<mypath>/microshift-image:tag
```
Replace <myregistry>, <myorg>, and <mypath> with your information.
- The BOOTC_IMAGE_URL variable contains a reference to the image that the ostreecontainer command installs. You can specify a z-stream release other than the latest by using the tag if required.
Optional. Add variables and values for registry authentication and configuration by using the following commands:
- Set the AUTH_CONFIG variable to authenticate access to the BOOTC_IMAGE_URL image by running the following command:
  $ export AUTH_CONFIG="$(cat ~/.quay-auth.json)"
  In this example, see the containers-auth.json(5) manual page for more information about this file format.
- Set the REGISTRY_CONFIG variable to configure access to the registry containing the BOOTC_IMAGE_URL image by running the following command:
  $ export REGISTRY_CONFIG="$(cat ~/.quay-config.conf)"
  In this example, see the containers-registries.conf(5) manual page for more information about this file format.

Create the kickstart.ks file to be used during the installation by running the following command:

envsubst < \
    /usr/share/microshift/kickstart/kickstart-bootc.ks.template > \
    "${HOME}/kickstart.ks"
