module: copy
version_added: "historical"
short_description: Copies files to remote locations.
description:
- The M(copy) module copies a file on the local box to remote locations.
options:
src:
description:
- Local path to a file to copy to the remote server; can be absolute or relative.
If path is a directory, it is copied recursively. In this case, if path ends
with "/", only inside contents of that directory are copied to destination.
Otherwise, if it does not end with "/", the directory itself with all contents
is copied. This behavior is similar to Rsync.
required: false
default: null
aliases: []
content:
version_added: "1.1"
description:
- When used instead of 'src', sets the contents of a file directly to the specified value.
required: false
default: null
dest:
description:
- Remote absolute path where the file should be copied to. If src is a directory,
this must be a directory too.
required: true
default: null
backup:
description:
- Create a backup file including the timestamp information so you can get
the original file back if you somehow clobbered it incorrectly.
version_added: "0.7"
required: false
choices: [ "yes", "no" ]
default: "no"
force:
description:
- the default is C(yes), which will replace the remote file when contents
are different than the source. If C(no), the file will only be transferred
if the destination does not exist.
version_added: "1.1"
required: false
choices: [ "yes", "no" ]
default: "yes"
aliases: [ "thirsty" ]
validate:
description:
- The validation command to run before copying into place. The path to the file to
validate is passed in via '%s' which must be present as in the visudo example below.
required: false
default: ""
version_added: "1.2"
others:
description:
- all arguments accepted by the M(file) module also work here
required: false
author: Michael DeHaan
notes:
- The "copy" module recursively copy facility does not scale to lots (>hundreds) of files.
For alternative, see "Delegation" section of the Advanced Playbooks documentation.

# Example from Ansible Playbooks
- copy: src=/srv/myfiles/foo.conf dest=/etc/foo.conf owner=foo group=foo mode=0644
