centos-minimal
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.
