Chapter 9. Enabling FIPS mode with RHEL image builder

Procedure

1. Create a plain text file in the Tom’s Obvious, Minimal Language (TOML) format with the following content:

   name = "system-fips-mode-enabled"
   description = "blueprint with FIPS enabled"
   version = "0.0.1"
   
   [customizations]
   fips = true
   
   [[customizations.user]]
   name = "admin"
   password = "admin"
   groups = ["users", "wheel"]

2. Build the customized RHEL image:

   # image-builder build image-type --blueprint blueprint-name

Verification

1. Log in to the system image with the username and password that you configured in your blueprint.

2. Check if FIPS mode is enabled:

   $ cat /proc/sys/crypto/fips_enabled
