===========================

-------------------------------------------------------------------
Build a basic Debian based container with debootstrap or mmdebstrap
-------------------------------------------------------------------

:manual section: 1
:manual group: Open Infrastructure

Synopsis
========

| **container build -s debootstrap** ['OPTIONS']
| **cnt b -s debootstrap** ['OPTIONS']

| **container build -s mmdebstrap** ['OPTIONS']
| **cnt b -s mmdebstrap** ['OPTIONS']

Description
===========

The debootstrap container build script uses debootstrap(8) or mmdebstrap(1)
to build a Debian based container.

This script builds a pure Debian system with three modificiations:

  * apt cache of packages downloaded during debootstrap is cleaned
  * hostname is set (container name) in /etc/hostname
  * root password is set (user specified or 16 random characters)

Options
=======

The following script options are available:

-n, --name='NAME':
  Specify container name.

-a, --architecture='ARCHITECTURE':
  Specify the Debian architecture, defaults to the host systems architecture.

-d, --distribution='DISTRIBUTION':
  Specify the Debian distribution, defaults to 'bookworm'.

-m, --mirror='MIRROR':
  Specify the Debian mirror, defaults to 'https://deb.debian.org/debian'.

-p, --root-password='PASSWORD':
  Specify the root password, defaults to a random 16 character password.

Examples
========

Build a Debian 12 (bookworm) based container with same architecture as the host
system using debootstrap:

  sudo container build -s debootstrap -n bookworm.example.net

Build a Debian 12 (bookworm) based container with different architecture as the
host system using mmdebstrap:

  sudo container build -s mmdebstrap -n bookworm-i386.example.net -- -a i386
