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 DIB_RELEASE
to 7
or 8
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 eth0
& 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
this to 0
. For CentOS 8, this is set to 0
by default as the
system uses NetworkManager by default.
