CDIST-TYPE__DOWNLOAD(7) cdist CDIST-TYPE__DOWNLOAD(7)

NAME

cdist-type__download - Download a file

DESCRIPTION

By default type will try to use curl, fetch or wget. 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 ...).

To change downloaded file's owner, group or permissions, use require='__download/path/to/file' __file ....

REQUIRED PARAMETERS

File's URL.

OPTIONAL PARAMETERS

Downloaded file's destination in target. If unset, $__object_id is used.
Supported formats: cksum output without file name, MD5, SHA1 and SHA256.

Type tries to detect hash format with regexes, but prefixes cksum:, md5:, sha1: and sha256: are also supported.

Checksum have two purposes - state check and post-download verification. In state check, if destination checksum mismatches, then content of URL will be downloaded to temporary file. If downloaded temporary file's checksum matches, then it will be moved to destination (overwritten).

For local downloads it is expected that usable utilities for checksum calculation exist in the system.

If local (default), then file is downloaded to local storage and copied to target host. If remote, then download happens in target.

For local downloads it is expected that usable utilities for downloading exist in the system. Type will try to use curl, fetch or wget.

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'.
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}'.
Execute this command after download.

__directory /opt/cpma
require='__directory/opt/cpma' \

        --url https://cdn.playmorepromode.com/files/cnq3/cnq3-1.51.zip \


        --sum 46da3021ca9eace277115ec9106c5b46
require='__download/opt/cpma/cnq3.zip' \


    __unpack /opt/cpma/cnq3.zip \
