module: synchronize
version_added: "1.4"
short_description: Uses rsync to make synchronizing file paths in your playbooks quick and easy.
description:
- This is a wrapper around rsync. 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. You still may need to call rsync directly via C(command) or C(shell) depending on your use case. The synchronize action is meant to do common things with C(rsync) easily. It does not provide access to the full power of rsync, but does make most invocations easier to follow.
options:
src:
description:
- Path on the source machine that will be synchronized to the destination; The path can be absolute or relative.
required: true
dest:
description:
- Path on the destination machine that will be synchronized from the source; The path can be absolute or relative.
required: true
dest_port:
description:
- Port number for ssh on the destination host. The ansible_ssh_port inventory var takes precedence over this value.
default: 22
version_added: "1.5"
mode:
description:
- Specify the direction of the synchroniztion. In push mode the localhost or delegate is the source; In pull mode the remote host in context is the source.
required: false
choices: [ 'push', 'pull' ]
default: 'push'
archive:
description:
- Mirrors the rsync archive flag, enables recursive, links, perms, times, owner, group flags and -D.
choices: [ 'yes', 'no' ]
default: 'yes'
required: false
existing_only:
description:
- Skip creating new files on receiver.
choices: [ 'yes', 'no' ]
default: 'no'
required: false
version_added: "1.5"
delete:
description:
- Delete files that don't exist (after transfer, not before) in the C(src) path.
choices: [ 'yes', 'no' ]
default: 'no'
required: false
dirs:
description:
- Transfer directories without recursing
choices: [ 'yes', 'no' ]
default: 'no'
required: false
recursive:
description:
- Recurse into directories.
choices: [ 'yes', 'no' ]
default: the value of the archive option
required: false
links:
description:
- Copy symlinks as symlinks.
choices: [ 'yes', 'no' ]
default: the value of the archive option
required: false
copy_links:
description:
- Copy symlinks as the item that they point to (the referent) is copied, rather than the symlink.
choices: [ 'yes', 'no' ]
default: 'no'
required: false
perms:
description:
- Preserve permissions.
choices: [ 'yes', 'no' ]
default: the value of the archive option
required: false
times:
description:
- Preserve modification times
choices: [ 'yes', 'no' ]
default: the value of the archive option
required: false
owner:
description:
- Preserve owner (super user only)
choices: [ 'yes', 'no' ]
default: the value of the archive option
required: false
group:
description:
- Preserve group
choices: [ 'yes', 'no' ]
default: the value of the archive option
required: false
rsync_path:
description:
- Specify the rsync command to run on the remote machine. See C(--rsync-path) on the rsync man page.
required: false
rsync_timeout:
description:
- Specify a --timeout for the rsync command in seconds.
default: 10
required: false
set_remote_user:
description:
- 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".
default: yes
required: false
notes:
- Inspect the verbose output to validate the destination user/host/path
are what was expected.
- The remote user for the dest path will always be the remote_user, not
the sudo_user.
- Expect that dest=~/x will be ~<remote_user>/x even if using sudo.
- To exclude files and directories from being synchronized, you may add
C(.rsync-filter) files to the source directory.
