The ubuntu-minimal
element uses debootstrap for generating a
minimal image. In contrast the ubuntu
element uses the cloud-image
as the initial base.
Note
You will need to install a working debootstrap for diskimage-builder. The version you install may not support all Debian and Ubuntu releases that you want to bootstrap. Consider using the zuul/nodepool-builder docker image instead as maximum compatibility is attempted there.
By default this element creates the latest LTS release. The exact setting can
be found in the ubuntu-common
element’s environment.d
directory in the variable DIB_RELEASE
. If a
different release of Ubuntu should be created, the variable DIB_RELEASE
can
be set appropriately.
Note that this element installs systemd-sysv
as the init system for
18.04+.
