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.
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:
- When set to 'yes', the task will fail if the remote file cannot be
read for any reason. Prior to Ansible-2.4, setting this would only fail
if the source file was missing.
- The default was changed to "yes" in Ansible-2.4.
required: false
choices: [ "yes", "no" ]
default: "yes"
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 appending
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.
requirements: []
author:
- "Ansible Core Team"
- "Michael DeHaan"
notes:
- When running fetch with C(become), the M(slurp) module will also be
used to fetch the contents of the file for determining the remote
checksum. This effectively doubles the transfer size, and
depending on the file size can consume all available memory on the
remote or local hosts causing a C(MemoryError). Due to this it is
advisable to run this module without C(become) whenever possible.
- Prior to Ansible-2.4 this module would not fail if reading the remote
file was impossible unless fail_on_missing was set. In Ansible-2.4+,
playbook authors are encouraged to use fail_when or ignore_errors to
get this ability. They may also explicitly set fail_on_missing to False
to get the non-failing behaviour.
