Recursive Copy In Ansible 1.5 And –diff

Posted by Jakub Holý on March 5, 2014

Ansible 1.5 has partial support for recursive copy of files:

  • the synchronize module, using rsync
    • cons: does not support group=, owner=
    • -C and –diff – it does not print diff of the files changed; when running ansible with -v, it will print output of rsync’s –itemize-changes, i.e., for each changed file/dir, something like “<…… conf/httpd.conf\n” (< = file uploaded, s = size changed, t = timestamp changed, . = this attribute has not been changed)
  • the copy module
    • -C –diff – it only reports “changed” without naming the changed files or showing diffs (unless there is only one changed file)
  • the local_action module, used to run rsync manually (essentially the same as synchronize but more control)
  • So the only way to do a kind of recursive copy with working diff is to use copy with with_fileglob for each directory and subdirectory😦

To check differences (without diff) manually:

rsync -e ssh -vrnc --itemize-changes source/dir myuser@myserver:/opt/dest/

where v= verbose, r = recursive, n = dry-run, c = check based on checksum, not timestamp+size; a typical output for a changed file is <fcsT...... httpd.conf (< = to be uploaded, f = it is a file, c = checksum differ, s = size differ, T = timestamp would be updated).

Sorry, the comment form is closed at this time.
