SYNOPSIS

vztmpl-dl [ option ... ] template [template ...]
: vztmpl-dl

DESCRIPTION

The main purpose of this utility is to download a precreated container tarballs (also known as templates) from the OpenVZ download server. It can be used directly from the command line, and is also used by vzctl create.

Usually one or more template names are required, except if one of --update-all, --list*, --config or --help is used.

OPTIONS

--gpg-check: Check GPG signatures of downloaded files. By default, GPG check is performed if CHECK_TEMPLATE_SIG is set to yes in /etc/vz/download.conf file, gpg(1) tool is installed, and the OpenVZ public key is available in the gpg keyring. See EXAMPLES section below on how to install OpenVZ public key.
--no-gpg-check: Do not check GPG signatures.
--ignore-errors: Keep processing templates from the list and return 0 exit code, even if some template failed to download. Without this option, vztmpl-dl aborts upon first download failure.
--update: Update (re-download) existing templates.
--no-update: Do not try to update existing templates.

--quiet: Be less talkative (currently it only adds --quiet flag to wget(1) ).
--no-quiet: Be more talkative (this can be used to negate the effect of QUIET=yes in download.conf.
--update-all: Try to update all templates that are available locally. Note that there is no need to specify individual templates. This options implicitly assumes --update and --ignore-errors options.
--list-remote: Output list of templates available for download. This option is also used by vzctl(8) bash-completion script to complete --ostemplate option arguments.
--list-local: Output list of templates available locally.
--list-all: Output combined list of templates.
--list-orphans: Output list of local templates not available remotely. In trivial scenario this will give the list of old templates that are no longer officially supported.
--config: Output current configuration. The tool has built-in configuration which can be overwritten by options in /etc/vz/download.conf file.
--help: Output help.

UPDATE_TEMPLATE: Default is yes. Setting to no has the same effect as using --no-update option.

QUIET: Default is no. Setting to yes has the same effect as using --quiet option.
TMPL_REPO_PREFIX: URL repo prefix. Default is http://download.openvz.org/template/precreated. Setting this to location of your closest OpenVZ download mirror can speed up download. Current list of OpenVZ mirrors is available at http://openvz.org/Download_mirrors.
