The 00-rhsm script is specific to RHEL6. If you use the REG\_ variables to

use with RHEL7, you do not need to set any DIB_RHSM variables. The scripts

named with "rhel-registration" have not been developed or tested for RHEL6.

Environment Variables for Module Selection during Image Creation
|
||||
----------------------------------------------------------------
|
||||
The following environment variable is used to select module streams to be
|
||||
enabled during an image build on RHEL8. Any existing stream for the given
|
||||
module is first disabled prior to enabling the specified stream.
|
||||
|
||||
#### DIB\_DNF\_MODULE\_STREAMS
|
||||
This is a space-separated list of module streams to enable prior to any
|
||||
RPMs being installed.

Image Build Module Selection Example
|
||||
------------------------------------
|
||||
When using Train on RHEL8.2, one must select the appropriate virt and
|
||||
container-tools module streams:

||||
|
||||
DIB_DNF_MODULE_STREAMS='virt:8.2 container-tools:2.0'
