+
+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://get.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

+
+CONTAINER IMAGES
+----------------
+
+compute-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.
