Create a minimal image based on CentOS
Use of this element will require ‘yum’ and ‘yum-utils’ to be installed on Ubuntu and Debian. Nothing additional is needed on Fedora or CentOS.
By default this builds CentOS 7 images. Set
8-stream to explicitly select the release.
For CentOS 7, by default,
DIB_YUM_MINIMAL_CREATE_INTERFACES is set
to enable the creation of
/etc/sysconfig/network-scripts/ifcfg-eth[0|1] scripts to enable
DHCP on the
eth1 interfaces. If you do not have these
interfaces, or if you are using something else to setup the network
such as cloud-init, glean or network-manager, you would want to set
0. For CentOS 8 and CentOS 8 Stream, this is set to
default as the system uses NetworkManager by default.
