16.47. cdist-type__download(7)¶

16.47.1. NAME¶

cdist-type__download - Download a file

16.47.2. 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 ...).

16.47.3. 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:.

16.47.4. 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.
