cdist-type__download - Man Page

Download a file

Description

Destination ($__object_id) in target host must be persistent storage in order to calculate checksum and decide if file must be (re-)downloaded.

By default type will try to use wget, curl or fetch. If download happens in target (see --download) then type will fallback to (and install) wget.

If download happens in local machine, then environment variables like {http,https,ftp}_proxy etc can be used on cdist execution (http_proxy=foo cdist config ...).

Required Parameters

url

File's URL.

sum

Checksum of file going to be downloaded. By default output of cksum without filename is expected. Other hash formats supported with prefixes: md5:, sha1: and sha256:.

Optional Parameters

download

If local (default), then download file to local storage and copy it to target host. If remote, then download happens in target.

cmd-get

Command used for downloading. Command must output to stdout. Parameter will be used for printf and must include only one format specification %s which will become URL. For example: wget -O - '%s'.

cmd-sum

Command used for checksum calculation. Command output and --sum parameter must match. Parameter will be used for printf and must include only one format specification %s which will become destination. For example: md5sum '%s' | awk '{print $1}'.

onchange

Execute this command after download.
