|
|
|
Provide yum specific image building glue.
|
|
|
|
|
|
|
|
|
|
RHEL/Fedora/CentOS and other yum based distributions need specific yum
|
|
|
|
|
customizations.
|
|
|
|
|
|
|
|
|
|
Customizations include caching of downloaded yum packages outside of the build
|
|
|
|
|
chroot so that they can be reused by subsequent image builds. The cache
|
|
|
|
|
increases image building speed when building multiple images, especially on
|
|
|
|
|
slow connections. This is more effective than using an HTTP proxy as a yum
|
|
|
|
|
cache since the same rpm from different mirrors is often requested.

|
Custom yum repository configurations can also be applied by defining
|
|
|
|
|
`DIB_YUM_REPO_CONF` to a space separated list of repo configuration files. The
|
|
|
|
|
files will be copied to /etc/yum.repos.d/ during the image build, and then
|
|
|
|
|
removed at the end of the build. Each repo file should be named differently to
|
|
|
|
|
avoid a filename collision.

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:3.0'
