CONTAINER-CREATE-DEBOOTSTRAP(1)
===============================
:doctype: manpage
:man manual: Open Infrastructure
:man source: container-tools
:man version: {revnumber}
NAME
----
container-create-debconf - Create an advanced Debian based container with debconf
SYNOPSIS
--------
*container create -s debconf* ['OPTIONS']
*container create -s debian* ['OPTIONS']
*container create -s progress-linux* ['OPTIONS']
DESCRIPTION
-----------
The debconf container creation script uses debconf(1) to automatically create a Debian based container.
SCOPE
~~~~~
Note that this container creation script can do a few things more than just automatically debootstrap based on a preseed file.
It also allows you to set a root password, configure the network, install certain packages and execute hooks.
But: this is *not* a replacement for a configuration management system (like ansible, puppet, etc.).
The intenion of this script is to create the initial container to that extend that a configuration managment system
can take over.
As an analogy, think of debian-installer: d-i sets up your system to make it ready to boot and connect to the network. Everything
after that is out of scope. Same goes for this script. (FIXME)
FUNCTIONS
~~~~~~~~~
This script performs the following configuration on top of a Debian based system:
* network
* root password
* apt repositories
* ...
MODES
~~~~~
This container creation script can be used under two different names: debian and progress-linux.
Alternative, calling it under the debconf name is equal to the debian mode.
INTERACTIVE/NONINTERACTIVE
~~~~~~~~~~~~~~~~~~~~~~~~~~
FIXME
PRESEEDING
~~~~~~~~~~
Hierarchy of Preseed Files
The debconf script can be fully preseeded. Such preseed files
can include one or more preseed files themselfs (currently, only one layer of
includes is supported, no nested or recursive includes).
The general rule of 'the later preseed file overwrites the earlier' applies.
The debconf script reads the main preseed file (specified either on command line or
by debconf selection/input dialog) after any included preseed files in there.
That means that debconf values after the include statement in the main preseed
file can overwrite any values specified in the included preseed files.
OPTIONS
-------
The following script options are available:
*-n, --name='NAME'*::
Specify container name.
*-p, --preseed-file='FILE'*::
Specify the preseed file.
EXAMPLES
--------
*Create a Debian based container:*::
sudo container create -s debian -n debian.example.net
*Create a Progress Linux container:*::
sudo container create -s progress-linux -n progress.example.net
