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:
|

|
rsync_opts:
|
|
description:
|
|
- Specify additional rsync options by passing in an array.
|
|
default:
|
|
required: false
|
|
version_added: "1.6"
|
|
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.
