|
|
|
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.

|
The yum repository can also be configured by defining `DIB_YUM_REPO_PACKAGE` as
|
|
|
|
|
a yum available package or a URL to an rpm file. This package can install repo
|
|
|
|
|
files with any associated keys and certificates.
