New in version 1.4.
synchronize
is a wrapper around rsync to make common tasks in your playbooks quick and easy. It is run and originates on the local host where Ansible is being run. Of course, you could just use the command
action to call rsync yourself, but you also have to add a fair number of boilerplate options and host facts. synchronize
is not intended to provide access to the full power of rsync, but does make the most common invocations easier to implement. You still
may need to call rsync directly via command
or shell
depending on your use case.parameter | required | default | choices | comments |
---|---|---|---|---|
archive | no | yes |
| Mirrors the rsync archive flag, enables recursive, links, perms, times, owner, group flags and -D. |
checksum (added in 1.6)
| no | no |
| Skip based on checksum, rather than mod-time & size; Note that that "archive" option is still enabled by default - the "checksum" option will not disable it. |
compress (added in 1.7)
| no | yes |
| Compress file data during the transfer. In most cases, leave this enabled unless it causes problems. |
copy_links | no | no |
| Copy symlinks as the item that they point to (the referent) is copied, rather than the symlink. |
delete | no | no |
| Delete files in dest that don't exist (after transfer, not before) in the src path. This option requires recursive=yes . |
dest | yes | Path on the destination host that will be synchronized from the source; The path can be absolute or relative. | ||
dest_port (added in 1.5)
| no | Value of ansible_ssh_port for this host, remote_port config setting, or the value from ssh client configuration if none of those are set | Port number for ssh on the destination host. Prior to ansible 2.0, the ansible_ssh_port inventory var took precedence over this value. | |
dirs | no | no |
| Transfer directories without recursing |
existing_only (added in 1.5)
| no | no |
| Skip creating new files on receiver. |
group | no | the value of the archive option |
| Preserve group |
links | no | the value of the archive option |
| Copy symlinks as symlinks. |
mode | no | push |
| Specify the direction of the synchronization. In push mode the localhost or delegate is the source; In pull mode the remote host in context is the source. |
owner | no | the value of the archive option |
| Preserve owner (super user only) |
partial (added in 2.0)
| no | Tells rsync to keep the partial file which should make a subsequent transfer of the rest of the file much faster. | ||
perms | no | the value of the archive option |
| Preserve permissions. |
recursive | no | the value of the archive option |
| Recurse into directories. |
rsync_opts (added in 1.6)
| no | Specify additional rsync options by passing in an array. | ||
rsync_path | no | Specify the rsync command to run on the remote host. See --rsync-path on the rsync man page. | ||
rsync_timeout | no | Specify a --timeout for the rsync command in seconds. | ||
set_remote_user | no | True | put user@ for the remote paths. If you have a custom ssh config to define the remote user for a host that does not match the inventory user, you should set this parameter to "no". | |
src | yes | Path on the source host that will be synchronized to the destination; The path can be absolute or relative. | ||
times | no | the value of the archive option |
| Preserve modification times |
use_ssh_args (added in 2.0)
| no | no |
| Use the ssh_args specified in ansible.cfg |
verify_host (added in 2.0)
| no | Verify destination host key. |

Note
synchronize
module, the “local host” is the host the synchronize task originates on
, and the “destination host” is the host synchronize is connecting to
.delegate_to
. This enables copying between two remote hosts or entirely on one remote machine.src
are those of the user running the Ansible task on the local host (or the remote_user for a delegate_to host when delegate_to is used).dest
are those of the remote_user
on the destination host or the become_user
if become=yes
is active..rsync-filter
files to the source directory.synchronize
module forces –delay-updates
to avoid leaving a destination in a broken in-between state if the underlying rsync process encounters an error. Those synchronizing large numbers of files that are willing to trade safety for performance should call rsync directly.This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
