module: fetch
|
|
short_description: Fetch files from remote nodes
|
|
description:
|
|
- This module works like M(ansible.builtin.copy), but in reverse.
|
|
- It is used for fetching files from remote machines and storing them locally in a file tree, organized by hostname.
|
|
- Files that already exist at O(dest) will be overwritten if they are different than the O(src).
|
|
- This module is also supported for Windows targets.
|
|
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: yes
|
|
dest:
|
|
description:
|
|
- A directory to save the file into.
|
|
- For example, if the O(dest) directory is C(/backup) a O(src) file named C(/etc/profile) on host
|
|
C(host.example.com), would be saved into C(/backup/host.example.com/etc/profile).
|
|
The host name is based on the inventory name.
|
|
required: yes
|
|
fail_on_missing:
|
|
version_added: '1.1'
|
|
description:
|
|
- When set to V(true), the task will fail if the remote file cannot be read for any reason.
|
|
- Prior to Ansible 2.5, setting this would only fail if the source file was missing.
|
|
- The default was changed to V(true) in Ansible 2.5.
|
|
type: bool
|
|
default: yes
|
|
validate_checksum:
|
|
version_added: '1.4'
|
|
description:
|
|
- Verify that the source and destination checksums match after the files are fetched.
|
|
type: bool
|
|
default: yes
|

flat:
|
|
version_added: '1.2'
|
|
description:
|
|
- Allows you to override the default behavior of appending hostname/path/to/file to the destination.
|
|
- If O(dest) ends with '/', it will use the basename of the source file, similar to the copy module.
|
|
- This can be useful if working with a single host, or if retrieving files that are uniquely named per host.
|
|
- If using multiple hosts with the same filename, the file will be overwritten for each host.

|
notes:
|
|
- When running fetch with C(become), the M(ansible.builtin.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 2.5 this module would not fail if reading the remote
|
|
file was impossible unless O(fail_on_missing) was set.
|
|
- In Ansible 2.5 or later, playbook authors are encouraged to use
|
|
C(fail_when) or C(ignore_errors) to get this ability. They may
|
|
also explicitly set O(fail_on_missing) to V(false) to get the
|
|
non-failing behaviour.
