centos-minimal

Create a minimal image based on CentOS 7.

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.

The DIB_OFFLINE or more specific DIB_YUMCHROOT_USE_CACHE variables can be set to prefer the use of a pre-cached root filesystem tarball.

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.
