+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.
+
+*--image='IMAGE'*::
+	Specify the image name to download, defaults to debian-stretch-${ARCHITECTURE}.tar.xz (where ${ARCHITECTURE} is the host systems architecture).
+
+*--server='SERVER'*::
+	Specify the image server to download from, defaults to https://files.open-infrastructure.net/images/container-tools/current.
+
+*-p, --root-password='PASSWORD'*::
+	Specify the root password, defaults to a random 16 character password.
+
+
+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 -- --image debian-stretch-i386.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 cache directory.
+
+
+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.
