# this is a virtual module that is entirely implemented server side
DOCUMENTATION = '''
---
module: fetch
short_description: Fetches a file from remote nodes
description:
- This module works like M(copy), but in reverse. It is used for fetching
files from remote machines and storing them locally in a file tree,
organized by hostname. Note that this module is written to transfer
log files that might not be present, so a missing remote file won't
be an error unless fail_on_missing is set to 'yes'.
version_added: "0.2"
options:
src:
description:
- The file on the remote system to fetch. This I(must) be a file, not a
directory. Recursive fetching may be supported in a later release.
required: true
default: null
aliases: []
dest:
description:
- A directory to save the file into. For example, if the I(dest)
directory is C(/backup) a I(src) file named C(/etc/profile) on host
C(host.example.com), would be saved into
C(/backup/host.example.com/etc/profile)
required: true
default: null
fail_on_missing:
version_added: "1.1"
description:
- Makes it fails when the source file is missing.
required: false
choices: [ "yes", "no" ]
default: "no"
validate_checksum:
version_added: "1.4"
description:
- Verify that the source and destination checksums match after the files are fetched.
required: false
choices: [ "yes", "no" ]
default: "yes"
aliases: [ "validate_md5" ]
flat:
version_added: "1.2"
description:
- Allows you to override the default behavior of prepending
hostname/path/to/file to the destination. If dest ends with '/', it
will use the basename of the source file, similar to the copy module.
Obviously this is only handy if the filenames are unique.
