Synopsis ¶

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.

Parameters ¶

Parameter	Choices/Defaults	Comments
archive boolean	Choices: no yes ←	Mirrors the rsync archive flag, enables recursive, links, perms, times, owner, group flags and -D.
checksum boolean added in 1.6	Choices: no ← yes	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 boolean added in 1.7	Choices: no yes ←	Compress file data during the transfer. In most cases, leave this enabled unless it causes problems.
copy_links boolean	Choices: no ← yes	Copy symlinks as the item that they point to (the referent) is copied, rather than the symlink.
delete boolean	Choices: no ← yes	Delete files in `dest` that don't exist (after transfer, not before) in the `src` path. This option requires `recursive=yes`.
dest - / required		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	Default: "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 boolean	Choices: no ← yes	Transfer directories without recursing
existing_only boolean added in 1.5	Choices: no ← yes	Skip creating new files on receiver.
group boolean	Choices: no yes Default: "the value of the archive option"	Preserve group
link_dest - added in 2.5	Default: null	add a destination to hard link against during the rsync.
links boolean	Choices: no yes Default: "the value of the archive option"	Copy symlinks as symlinks.
mode -	Choices: pull 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 boolean	Choices: no yes Default: "the value of the archive option"	Preserve owner (super user only)
partial boolean added in 2.0	Choices: no ← yes	Tells rsync to keep the partial file which should make a subsequent transfer of the rest of the file much faster.
perms boolean	Choices: no yes Default: "the value of the archive option"	Preserve permissions.
private_key - added in 1.6		Specify the private key to use for SSH-based rsync connections (e.g. `~/.ssh/id_rsa`)
recursive boolean	Choices: no yes Default: "the value of the archive option"	Recurse into directories.
rsync_opts - added in 1.6	Default: null	Specify additional rsync options by passing in an array.
rsync_path -		Specify the rsync command to run on the remote host. See `--rsync-path` on the rsync man page. To specify the rsync command to run on the local host, you need to set this your task var `ansible_rsync_path`.
rsync_timeout -	Default: 0	Specify a `--timeout` for the rsync command in seconds.
set_remote_user -	Default: "yes"	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 - / required		Path on the source host that will be synchronized to the destination; The path can be absolute or relative.
times boolean	Choices: no yes Default: "the value of the archive option"	Preserve modification times
use_ssh_args boolean added in 2.0	Choices: no ← yes	Use the ssh_args specified in ansible.cfg
verify_host boolean added in 2.0	Choices: no ← yes	Verify destination host key.

Notes ¶

Note

rsync must be installed on both the local and remote host.
For the synchronize module, the “local host” is the host the synchronize task originates on, and the “destination host” is the host synchronize is connecting to.
The “local host” can be changed to a different host by using delegate_to. This enables copying between two remote hosts or entirely on one remote machine.
The user and permissions for the synchronize 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).
The user and permissions for the synchronize dest are those of the remote_user on the destination host or the become_user if become=yes is active.
In 2.0.0.0 a bug in the synchronize module made become occur on the “local host”. This was fixed in 2.0.1.
Currently, synchronize is limited to elevating permissions via passwordless sudo. This is because rsync itself is connecting to the remote machine and rsync doesn’t give us a way to pass sudo credentials in.
Currently there are only a few connection types which support synchronize (ssh, paramiko, local, and docker) because a sync strategy has been determined for those connection types. Note that the connection for these must not need a password as rsync itself is making the connection and rsync does not provide us a way to pass a password to the connection.
Expect that dest=~/x will be ~<remote_user>/x even if using sudo.
Inspect the verbose output to validate the destination user/host/path are what was expected.
To exclude files and directories from being synchronized, you may add .rsync-filter files to the source directory.
rsync daemon must be up and running with correct permission when using rsync protocol in source or destination path.
The 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.
link_destination is subject to the same limitations as the underlaying rsync daemon. Hard links are only preserved if the relative subtrees of the source and destination are the same. Attempts to hardlink into a directory that is a subdirectory of the source will be prevented.
