CONTAINER-CREATE-CURL(1)
========================
:doctype: manpage
:man manual: Open Infrastructure
:man source: container-tools
:man version: {revnumber}


NAME
----
container-create-curl - Create a Debian based container by downloading a tarball over the network


SYNOPSIS
--------
*container create -s curl* ['OPTIONS']


DESCRIPTION
-----------
The curl container creation script uses curl(1) to download a tarball over the
network to create a Debian based container.

Depending on the tarball this script otherwise creates a pure Debian system with three modificiations:

  * hostname is set (container name) in /etc/hostname
  * systemd machine-id is generated in /etc/machine-id
  * 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 container architecture.

"--clean*::
	Remove downloaded tarball after successfull container creation.

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

*--server='SERVER'*::
	Specify the image server to download from, defaults to https://files.open-infrastructure.net/system/container/debian.

*--setup='SETUP'*::
	Specify the setup image name to download, defaults to the value specified through --system using the setup.tar.${COMPRESSION} suffix.

*--system='SYSTEM'*::
	Specify the system image name to download, defaults to debian-stretch-current_${ARCHITECTURE}.system.tar.${COMPRESSION} (where ${ARCHITECTURE} is the host systems architecture and ${COMPRESSION} either lz, xz, or gz depending on compressor availability on the host system).


EXAMPLES
--------
*Create a Debian 9 (stretch) based container with same architecture as the host system:*::
	sudo container create -s curl -n stretch.example.net

*Create a Debian 9 (stretch) based container with different architecture as the host system:*::
	sudo container create -s curl -n stretch-i386.example.net -- --system debian-stretch-current_i386.system.tar.xz

FILES
-----
The following files are used:

*/etc/container-tools/config*::
	Container configuration files.

*/usr/share/container-tools/scripts*::
	Container creation scripts.

*/usr/share/doc/container-tools*::
	Container documentation.

*/var/lib/machines*::
	Container directory.

*/var/cache/container-tools*::

CONTAINER IMAGES
----------------

container-tools will download tarballs from a server expecting that the images are tarballs with either gzip, lzip, xz, or no compression. See container-images.sh as an example on how to create your own container images.
