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.
